The
eRez application is an advanced Web application that uses the latest
Web technology. In order to get full use from the application and to
see pages displayed properly you should use a recent browser that
supports HTML 4.0. eRez uses advanced JavaScript for navigation.
Recommended browsers include Internet Explorer 5 or higher, Safari 1.1
or higher, Netscape 6 or higher as well as other Gecko based browsers
such as Mozilla. One of the reasons for targeting advanced browsers is
to provide a better interface and to build pages that meet World Wide
Web Consortium standards. In order to keep track of your session you
must have session-based Cookies enabled on your browser.
If you plan to use the Flash based FSI Viewer you need the Macromedia Flash Player version 6 or later
Log in to eRez
The
lowest access level in eRez is the anonymous user. If you omit typing a
name you login as an anonymous user. What you can do as an anonymous
user depends on what the server administrator allows you - usually not
that much.
To login as a named user eRez
requires a user name and a password. The user name and password is
assigned to you by the administrator of the eRez system you want to log
in to. Please notice that different security levels can be assigned to
individual user names, allowing users different access and editing
rights.
Check the "Use Flash" checkbox
to enable the FSI Viewer and FSI Showcase. If you have not obtained an
FSI Viewer license the viewer will run in evaluation mode.
You
are also offered the possibility of choosing the language of the eRez
browser. eRez automatically looks up the language settings of your
browser and determines if your preferred language is among the
languages eRez supports. If it is, it suggests your preferred language
to you. If your preferred language is not available, eRez looks up your
other language preferences, and if they are also unavailable it
suggests English. However, you may also choose a language from the
dropdown box when you log in.
Please contact your server administrator if you want your access rights changed.
eRez
can be set-up to allow all or part of the eRez folders accessible
without Log in. Folders accessible to all do not require any login.
If you are an administrator running on an eRez ASP version, you might want to taylor to add a &configuration=[sub-configuration name] to the URL you give to your users, as this will allow them to log in to the particular configuration.
Log In. If you are not logged into eRez,
click on this button in the top right corner to Login. Log in requires
a user name and a password. With a Log in you gain access to the shared
folders in eRez accessible by your user name. What you will typically
see when logged in is that the list of folders in the Tree view expands
with additional folders accessible to your user name.
Log Out. Log out. To log out, click on this button in the top right corner.
The eRez Browser
Tree View
The folder
tree gives you a hierarchical view of the folders accessible to you in
the eRez browser. Click on individual folder names to display their
content in the Content frame .
With
eRez 5 there is now both a Flash based Tree View and an Ajax based Tree
view. In the following we will describe the Ajax based Tree View,
however the Flash based tree view is very similar.
Reloads the list and collapses the tree
This Server is the top level of the tree and will show the name of your eRez server
Expands a level in the tree
Expands the level in the tree and updates the Content frame
Contracts the level in the tree
Updates the Content frame
Content frame
The
content frame displays images and subfolders in the current folder you
are viewing, the result of a search, a list of files ready for download
or the images you have selected.
When
displaying a folder in eRez you are viewing small thumbnails of the
images available in that folder. You can change the layout of the
content frame - the number of images displayed on a page – by adjusting
the size of thumbnails in the lower right corner. If you resize your
browser window the number of thumbnails in the content frame will also
change.
Scrolling through pages
eRez
shows the images in a given folder as pages. The number of pages
displayed depends on the amount of images and folders as well as the
layout selected. In the example below, page 8 is viewed, and there are
a total of 14 pages. You can scroll back and forth between pages by
clicking on the and buttons, or by selecting a specific page to view. The number of the current page viewed is displayed in bold.
List parent folder
To move up one level in the tree hierarchy click on the List parent folder. Both the content frame and content info is updated.
Selecting and viewing individual images
Move
your mouse over a thumbnail in the content frame and eRez makes a
slight zoom into the image. This feature makes it obvious what image
you are currently viewing. If you keep the mouse over the same image
for a few seconds, a larger version is also displayed in the content info frame.
If you check an image from the list it is added to your selections.
Great tip: If you hold down your SHIFT key and click on the
box beneath the thumbnail you automatically selects ALL images in that
folder. If you want to deselect all images hold down your SHIFT key
again and click on the .
For more information on selections, please go to The selection tab .
If
you click on an image you will be able to see the image and all the
information available about that image in the whole content frame.
In
this example we are viewing an image from a desert. If you would like
to see more details in the sand, you can click anywhere in the image to
zoom into it.
Hint:
If you want to view the image in the whole content frame – without all
the image information - please click on "view" icon in the navigator
top.
If you are running on a FSI Viewer supported eRez Server you will see the image in the FSI Viewer. Please refer to the FSI Viewer section for information about navigating in the FSI Viewer.
If you don't have FSI viewer enabled, you can reload the image click on the button underneath the image.
Click on the in the top left corner of the content frame to return to the list of thumbnails.
Clipping path info - if available - can be seen underneath the image.
A
camera or a scanner stores information about an image. eRez extracts
this information from the image and displays it to you when you are
viewing the image. Some information, such as File: Preview: and Image:
will always be there. Depending on information stored within the image,
other types of information will also be displayed. Such information can
be IPTC as described later or
EXIF data. EXIF stands for Exchangeable Image File Format, and is a
standard for storing interchange information in image files, especially
those using JPEG compression. Most digital cameras now use the EXIF
format.
If you want to know more about the information stored in images, please see the section on Edit Image Information .
Content Info frame
The
content info frame displays information about folders or images
depending on what is currently selected. If a folder is selected, eRez
can display certain types of information or even an image to symbolize
the folder. Typically eRez displays the name of the selected folder or associated notes .
If
you place your mouse over an image, eRez will display a preview of that
image after a few seconds delay. You can zoom into such a preview,
exactly the same way you can when viewing an individual image. This can
be quite handy for quickly browsing through images and perhaps looking
for special details in an image.
Searching
You can search for images by entering one or more words in the search
field and click on search. Searching refreshes the content frame, and
displays the matching images sorted by relevance. The search engine
within the eRez Server searches inside all image information and meta
information. The eRez Server can even be configured for searches inside
PDF documents. Special plug-ins can be developed for the eRez Server
that allows users to search inside other types of documents. This
however is special configuration and developments that varies from eRez
server to eRez server.
The searches
done by the eRez Server are very similar to the way search engines like
Google or Yahoo searches for and displays results.
Advanced Searching
Like
most of the advanced search engines you encounter on the Internet, the
eRez Server also enables advanced searching capable of qualifying your
search and results.
The words that you enter in the search field are called a "query". A query is broken up into terms and operators.
A term can be of two different types: Single Terms and Phrases. - Single Terms is a single word such as "marketing" or "product".
marketing
- Single Terms is a single word such as "marketing" or "product".
"please note"
You
can combine multiple terms with Boolean operators to form a more
complex query. A Boolean operator is a logical operator that tells the
eRez Servers search engine how terms and phrases should be combined to
a more complex query. Boolean operators must be ALL CAPS (capital
letters).
OR
The OR operator is the default conjunction operator. This means
that if there is no Boolean operator between two terms, the OR operator
is used. The OR operator links two terms and finds a matching document
if either of the terms exist in a document. This is equivalent to a
union using sets. The symbol || can be used in place of the word OR.
To search for documents that contain either "red flower" or just "carrot" use the query:
"red flower" carrot
or
"red car" OR carrot
AND
The AND operator matches documents where both terms exist anywhere
in the text of a single document. This is equivalent to an intersection
using sets. The symbol && can be used in place of the word AND.
To search for documents that contain "red car" and "green car" use the query:
"red car" AND "green car"
+
The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document. To search for documents that must contain "tomato" and may contain "green" use the query:
+tomato green
NOT
The NOT operator excludes documents that contain the term after
NOT. This is equivalent to a difference using sets. The symbol ! can be
used in place of the word NOT. To search for documents that contain "red car" but not "red carrot" use the query:
To search for documents that contain "red car" but not "red carrot" use the query:
"red car" NOT "red carrot"
-
The "-" or prohibit operator excludes documents that contain the term after the "-" symbol. To search for documents that contain "red car" but not "red carrot" use the query:
"red car" -"red carrot"
Grouping
You can use parentheses to group clauses to form sub queries. This
can be very useful if you want to control the boolean logic for a query. To search for either "red" or "car" and "website" use the query:
(red OR car) AND website
This eliminates any confusion and makes sure you that website must exist and either term red or car may exist.
It is also possible to qualify your search even more
Wildcard Searches
The term "wild card" originates from the card game of poker, where
a card such as the Joker may by agreement represent any other card in
the pack. A wildcard search uses a special symbol to allow you to
search simultaneously for several words with the same term.
You can use both single and multiple character wildcard searches.
?
To perform a single character wildcard search use the "?" symbol. It looks for terms that match that with the single character replaced.
te?t
*
To perform a multiple character wildcard search use the asterix "*" symbol.
a*d
Will find results such as "badger", "around" and "bandstand". Please note that the search engine doesn't allow you to start with "*". You can't search for *ing".
Proximity Searches ~
Finding words are a within a specific distance away is also
supported. To do a proximity search use the tilde, "~", symbol at the
end of a Phrase.
roam~
Will find terms like "foam" and "roams".
Fuzzy Searches ~
To do a fuzzy search use the tilde, "~", symbol at the end of a single word term. It finds spelling that is similar to the search term.
" european bison"~10
This search will find a "bison" and "european" within 10 words of each other.
Boosting a Term ^
The search engine provides the relevance level of matching
documents based on the terms found. To boost a term use the caret, "^",
symbol with a boost factor (a number) at the end of the term you are
searching. The higher the boost factor, the more relevant the term will be.
Boosting allows you to control the relevance of a
document by boosting its term. For example, if you are searching for
bison european
and you want the term "bison" to
be more relevant boost it using the ^ symbol along with the boost
factor next to the term. You would type:
bison ^4 european
Which will make images with the term bison appear more relevant?
You can also boost phrase terms:
" red car" ^4 " green car"
By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)
Escaping Special Characters
\
You can escape special characters that are part of the query syntax. The current list special characters are
+ - && || ! ( ) { } [ ] ^ " ~ * ? : \
To escape these character use the \ before the character. For example to search for (1+1):2 use the query:
\/1\+1)\:2
Navigator - actions in eRez
Navigator mode
The tabs on the Navigator bar at the top of the eRez browser displays different sets of actions.
"List"
tab displays the "File List", that is either the content of the last
folder or a search result you viewed. If you click on a folder in the
navigation tree the tab displayed will automatically be reset to "List".
The "File" tab remembers the last individual file you either
viewed or edited. If you are viewing or editing a file the tab
displayed will be the "File" tab.
The "Selected files" tab displays files you’ve selected by checking them
. You can consider the images in selected files tab as a kind of
"on-the-fly" folder, containing files you want to work with in some
way. However, the files in the selection need not be "lost" when you
log off. For more information please see selected files functions
Each
tab also enables different functions. Whether a function is enabled or
disabled depends on your previous actions and the privileges awarded
you by the eRez server administrator.
The List tab - List files functions
When you are
viewing the contents of folder eRez displays the List Navigator tab.
Some of the functions found here are identical to what you find in the
other tabs – however when in the List tab remember you are working at
folder level. If you click on the List tab, you get the last folder
viewed in the content frame.
The File tab - Individual file functions
The
File tab concerns functions dealing with individual files, be they
images or other file types such as Microsoft Word documents, PDF-files
etc. If you click on the File tab you will automatically get the last
file viewed in the content frame.
The selection tab - Selected files functions
The
selection tab is a very special tool. When you are browsing through
files on the eRez server you can mark individual files for selection by
checking them underneath their thumbnails in the checkbox ( ). Files you have selected can be viewed in the selection tab.
If you hold down your SHIFT key and click on the box beneath the thumbnail you automatically selects ALL images in that folder. If you want to deselect all images hold down your SHIFT key again and click on the . When you are viewing files in your selection you can therefore deselect them all this way.
Your
selection of files can be considered as a kind of “on-the-fly” folder,
where you collect all the files you want to do something with.
When
you log off the selection is reset, however it need not be lost! A
selection is actually saved on the eRez server with a special number.
This means that it can be retrieved from the server again. One example
of how access a selection is to send an email with a link to Selected
Files. Another is to Publish Selection to Web . The html code you generate will retrieve the selection when you call that code.
As the selection behaves like a folder, many of the functions are similar to what you find in the List tab.
Hint for the very advanced user:
In the html code generated when you publish to web the name of the
query is stored as an item in the URL you call eRez with to retrieve
your selection. This name can be extracted from the html code.
Depending on whether you published as a slideshow, a FSI showcase etc.
the keyname is called something with “query=”. The item after the key
starting with a ~ and a long name is actually the name of the
selection. Examples:
query=~a5e165514b9b0284de5b0f7dd3a2f82d
showcase_query=~a5e165514b9b0284de5b0f7dd3a2f82d
If
you extract the ~a5e165514b9b0284de5b0f7dd3a2f82d you can later search
for the selection with that name with the search function.
Start Slideshow
Start Slideshow. eRez offers you a very practical way of browsing through images in a folder or a selection
- and in a format that makes viewing and evaluating images a breeze.
The Slideshow runs through all images in a folder or a selection and
displays them for roughly 10 seconds and then fade in the next image.
Slideshow without flash viewer
The content info frame
also changes and displays some very handy slideshow navigation buttons.
The left button takes you back to the previous image, the middle button
pauses the slideshow and the right button forwards you to the next
image. To view the slideshow in full screen mode, just click on
the current image displayed in the slideshow. To return from full
screen mode to the eRez browser, again just click on the image. If you want to return to viewing folder content, click on the
List tab .
Slideshow with flash viewer
If you are running on an eRez system with flash enabled you will have
slideshow navigation buttons within the slideshow. Move your mouse onto
the upper left corner of the image being viewed, and the navigation bar
appears.
Restarts the slideshow from the first image
Takes you on image back in the slideshow
Pauses the slideshow
Forwards you to the next image in the slideshow
Is the counter. You are now viewing image number 3 out of 21 images.
The small blue dot within the counter lights yellow whenever the
slideshow is ready with a new image for you to view.
Just click on the image being displayed in the slideshow to select and view the individual it. This also stops the slideshow.
Upload New Images
Publish Files to Web. If you are assigned
upload privilege in the current folder you can add new images by
"uploading them". You can also choose to create a new folder where new
images will be placed.
If
you are not privileged to upload to a folder the upload icon is
"dimmed". If your session has timed out, you will see the following
warning:
ACCESS DENIED
You do not have permission to perform the selected operation in this folder.
In this example, the current folder is called "Upload here - unrestricted" and you are about to upload images to that folder.
You can specify up to 5 uploads for each upload session.
You can opt to receive an Email receipt to a specified e-mail address here called me@mySystem.com.
You can opt to create a new folder,
which automatically becomes a sub-folder to the current one. eRez will
automatically place the files you specify to upload in this new folder.
Please remember to check the "create new folder" option, and remember
to specify the name of the new folder.
If you upload zip files:
Unpack Files. If you upload a ZIP archive, eRez will extract all the files and unpack it it the folder you upload to.
Unpack Files and Folders.
If you upload a ZIP archive, eRez will unpack the files and folder
structure and place it relative to the folder you are in. This means
that if you have a folder structure, eRez can recreate it for you!
Leave as ZIP files. eRez will not unpack the ZIP file, but leave it as it is in the folder you upload to.
Finally you can add IPTC caption and keywords to your files. Caption is a textual description of the image. Keywords are used to indicate specific information retrieval words. Each keyword is separated by a line break.
Caution! Please be careful, if you check the box "Overwrite IPTC values" you will overwrite all IPTC information
in your uploaded files, even IPTC information not included by the eRez
server administrator in the upload menu. This is the same as clearing
or deleting IPTC fields within the images not included in the upload
menu.
What kind of files can be uploaded?
You can upload:
TIFF
FPX (FlashPix images)
PSD (Native Photoshop Images)
JPEG
GIF
EPS
PDF
AI (Adobe Illustrator Drawings)
SVG
CAD (DWG, DXF and DWF – AutoCad formats)
Plus additional formats which have been configured by the eRez server administrator.
A ZIP archive containing one or more of the above formats.
...Plus
an additonal 500+ file formats. eRez will not be able to let you view
or zoom into them, but you can store them on eRez. When viewing them in
the content frame, or list tab you will see an icon representing the
file format.
If you upload GIF,
JPEG images or (TIFF images with no pyramid extensions) they are
automatically optimized and converted by the eRez server to a TIFF
image file with pyramid extensions. TIFF images with pyramid extensions
as well as FlashPix images are not converted.
PSD
files must be stored with “maximum compatibility” checked in order to
be used with eRez. Since PSD files only contain a single resolution,
eRez will automatically create the missing resolutions and store them
in a hidden preview file. Until this process has been completed the
image may temporarily show up as a grey box.
EPS,
PDF and Adobe Illustrator files normally contain vector based graphics
or line art used in logos and such. eRez will automatically try to
create a preview of the first page for your EPS, PDF and Adobe
Illustrator files if your server administrator has installed Ghostscript
and configured eRez to use it. Otherwise if a TIFF preview exists
inside an EPS file it will be shown as a thumbnail or when viewing a
file. Otherwise a generic icon will be shown instead of the thumbnail
for EPS, PDF and Illustrator files.
In
SVG and the other vector based formats such as DWG, DXF and DWF eRez
saves the original files but creates SVG based previous for when you
view the files as thumbnails.
Trick!
You can upload more than 5 files at a time by zipping them into an
archive and then uploading it. Please notice that paths defined in the
ZIP archive are ignored by the eRez server. All supported image files
in the ZIP archive will be placed in the current folder or the
specified new folder. Please note that the names of the individual
files in a ZIP file must be ASCII characters only (no special
characters such as the Æ , Ø and Å).
When you have specified files to upload, click on the Send Files. The following message will appear in the upload window:
Uploading your files.
Please do not close this window until the transfer is complete.
As noted in the window it is important that you do not close the window! Otherwise your upload transfer is disrupted and no files are transferred.
As
noted in the window it is important that you do not close the window!
Otherwise your upload transfer is disrupted and no files are
transferred.
The files you uploaded do
not become visible in the tree view and content frame before you
refresh the windows. To refresh, click on the File list tab
in the Navigator frame. If you upload many images that need to be
converted they will not appear until after the server conversion
process has finished.
Why use TIFF images?
TIFF
is an open standard and by far the most versatile, reliable, and widely
supported image format in use. eRez utilizes the multi-resolution
information standard created by Adobe in 1996 to build so called
pyramid TIFF files. The most important characteristic of this format is
that the image file is organized in a way that makes it possible to
read parts of the image at various resolution levels very fast.
The
pyramid TIFF format has been designed to be backwards compatible with
other software packages. Although these packages might not be able to
take advantage of the multi-resolution image data they will still be
able to read the image at the full resolution. Even Adobe Photoshop
itself is unable to take advantage of the sub-resolutions and will
always read the full resolution.
Because
JPEG files are single resolution files they should not be used with the
eRez Imaging Server if they contain more than a few megabytes of
uncompressed image data (low resolution files at screen resolution).
Using higher resolution JPEG images will slow down the eRez Imaging
Server considerably.
FlashPix is
another multi-resolution format created by KODAK, HP and Microsoft.
Some of the advantages of pyramid TIFF compared to FlashPix are the
support for CMYK and ciLAB color spaces, support for 16-bit per channel
data as well as support for embedded ICC profiles, transparency,
Photoshop layers, clipping paths, IPTC and EXIF metadata. In addition
pyramid TIFF supports lossless compression by means of LZW and ZIP.
A Pyramid TIFF file contains image data at multiple resolutions.
Edit Folder Information
Edit Folder. You can edit information about
the current folder by clicking on the "Edit Folder Information" button
in the Navigator frame. This assumes that you are privileged to edit
the folder information. All first level folders – those directly
underneath the root, can only be edited by the eRez administrator.
If you are not privileged to edit folder information, a warning is issued, telling you that access is denied.
Info for Folder:Samples/mirror image test pages:
Folder Name:
Mirror image test pages
Notes:
This folder contains low resolution variations of the same image in various color spaces.
Demonstrates how colors are converted on-the-fly using ICC profiles.
As you
can see you can edit the name of the folder, and additional notes to be
displayed in the Content Info Frame. You can also create a new folder
here.
The folder Notes are inherited by all the sub-folders. However, if
you insert a new folder note for a sub-level folder, it of course, will
take precedence.
Click
on “Move Folder” in the lower left corner to move the folder and all
its content to a new location. This will bring up a new page with a
list of target folders. Click on a folder to complete the move.
If you are accesing
eRez with Flash enabled, you will see a flash based Move Folder
component. Select your target folder and click on:
Move Folder. To begin moving the folder
Cancel. To cancel and go back to list view.
Delete Folder
Delete FolderIf you are privileged to do it,
you can delete an entire folder and all of it's sub-folders. So if
sub-folders to the folder you want to delete exist, you'll also delete
all the sub-folders
Are you sure you want to delete folder "Test" and all its content?
This can not be undone
Email FolderWhen you e-mail a folder to
someone you actually send them an e-mail with a link to the folder. In
this example reinhard@yawah.com is sending a link to MImages to
bisp@voldsomvolvo.com. The e-mail will contain the message and a
hyperlink to the folder on the eRez server.
Please notice! If the folder is not accessible for all: Remember to include access information to the folder in your e-mail message.
Otherwise the recipient of your e-mail will be very frustrated when he
or she is asked for username and password of which they have no
knowledge.
Image Information
Show File InformationWhen you click on an image thumbnail in the content frame , the content frame will display the image and Image Information.
Download Image
is a powerful feature that lets you define what part of the image to
retrieve from the eRez server as well as the format and quality of the
downloaded image.
In the top left corner you can select part or the entire image to download. To "crop" an image simply drag the handles in the image using the mouse to select the area that you want to download.
Drag the handles to resize the selection without altering the center.
To move the entire selection click on the inside of the select frame.
Additionally
you can zoom in and out for a more precise selection using the buttons
below the crop image. By pressing one of the mouse mode buttons (zoom,
pan, rotate) you can choose the mouse function outside the selection.
Note:
If your Browser does not support Flash you will get a simpler interface
without the possibility to zoom, pan and rotate the selection.
If you want to download the whole image without cropping it, just leave the handles be.
eRez
can create an endless number of derived variations from a single source
image. Depending on how you are going to use an image you will need the
image prepared with a size, resolution, format, sharpening and color
definition that meets the requirement of the target medium and context.
To avoid having to deal with all these details every time an image is
downloaded eRez uses predefined templates with information
about all the technical details for a specific medium. These templates
can be added and modified by the server administrator.
When
eRez is first installed the download page will give you the choice of
about 30 standard templates divided into 3 categories:
Desktop Presentation (72 DPI) - for display on a computer screen, i.e. in a Microsoft PowerPoint presentation.
Desktop Printing (144 DPI) - for printing on an office inkjet or laser printer.
Professional Printing (300 DPI) - for printing on professional 4 color printing presses.
The
eRez server administrator may have configured your eRez server
differently to better match the specific needs or your organization.
The formats available on the standard download page should be
configured to meet the day-to-day requirements. If you find that a
particular format you need on a regular basis isn't available on the
standard download page you should ask your server administrator to add
it.
Choosing the right resolution:
DPI is short for "Dots Per Inch" and defines the number of dots - or
pixels - needed for each inch of paper or screen in order to get a good
result. An image file at 300 DPI is roughly 18 times larger than an
image with the same dimensions at 72 DPI and 4 times larger than an
image with the same dimensions at 144 DPI.
Nothing is gained by working with an image with a resolution too high
for the purpose. So pick the right resolution and save download time
and storage space.
Download PDF files
If you download PDF files you will not see all these options. Downloading a PDF file gives you three options:
Download OriginalAdds the PDF file to the Download manager , where eRez prepares the makes a ZIP file containing the PDF file as well as a ZIP file with all your selected downloads.
Open OriginalLets
you open the original PDF in your browser. If you have a PDF viewer
installed the PDF viewer will open the PDF file, otherwise you are
prompted to save the PDF file to your disk.
Advanced Options
You
may need to enter the "Advanced Options" in situations where you need a
slightly larger preview for more accurate cropping, need to rotate an
image or want to override one or more of the settings for a particular
template. In addition to cropping and rotation the "Advanced Options"
allows you to choose an existing template and override the settings for
ICC color profile, image file format, width, height and resolution.
Base Template:Approx.
30 different base templates come pre-installed with the eRez server.
The server administrator may however decide to make new ones available
or delete some.
ICC Profile:eRez follows the color management conventions developed by the
International Color Consortium (ICC). An ICC profile systematically
describes how color numbers map to a particular color space, usually
that of a device such as a scanner, printer, or monitor. From the ICC
profile drop down menu you can choose between all of the ICC profiles
available on the server. The professional printing standards used in
Europe, USA and Asia all use different inks and different printing
processes such as offset or gravure and therefore requires different
ICC profiles as well.
eRez comes with
the 3 generic profiles and 4 profiles CMYK offset printing as listed
below. Chances are good that your server administrator has already
added additional ICC profiles that match the CMYK printing standards
used by your organization.
The generic profiles are:
Generic CMYK
- a generic \"one-size-fits-all\" CMYK profile. Should only be used
when no other ICC profile is available for professional printing.
Greyscale - a standard \"black & white\" profile for use with greyscale printers or a standard computer monitor.
sRGB - a standard RGB profile for use with a standard computer monitor.
The profiles for CMYK offset printing are:
ISO Coated - for offset printing on glossy or matte coated paper.
ISO Uncoated Yellowish - for offset printing on yellowish uncoated paper.
ISO Uncoated - for offset printing on white uncoated paper.

Rendering Intent:The
rendering intent determines how eRez handles the ICC color conversion.
The rendering intent you choose depends on whether colors are critical
in an image and on your preference of what the overall color appearance
of an image should be.
You may choose from the following rendering intents:
Perceptual
- Aims to preserve the visual relationship between colors so it''s
perceived as natural to the human eye, even though the color values
themselves may change. This intent is suitable for photographic images
with lots of out-of-gamut colors.
Saturation-
Tries to produce vivid colors in an image at the expense of color
accuracy. This rendering intent is suitable for business graphics like
graphs or charts, where bright saturated colors are more important than
the exact relationship between colors (such as in a photographic image).
Relative Colorimetric-
Compares the extreme highlight of the source color space to that of the
destination color space and shifts all colors accordingly. Out-of-gamut
colors are shifted to the closest reproducible color in the destination
color space. Relative colorimetric preserves more of the original
colors in an image than perceptual.
Absolute ColorimetricAbsolute
Colorimetric - Leaves colors that fall inside the destination gamut
unchanged. Out of gamut colors are clipped. No scaling of colors to
destination white point is performed. This intent aims to maintain
color accuracy at the expense of preserving relationships between
colors and is suitable for proofing to simulate the output of a
particular device.
If you
leave the value blank, the rendering intent specified in the template
or the ICC profiles default rendering intent will be used.
Please note that some ICC profiles produce the same result regardless of the requested rendering intent.
Black Point Compensation:Black
Point Compensation (BPC) is a technique used in digital photography
printing. It ensures that the shadow detail in the image is preserved
by simulating the full dynamic range of the output device - essentially
making black more black. BPC can be used when transforming files using
ICC profiles form CMYK to RGB.
As
black is not always totally black in CMYK, it will be mapped to
something not completely black in RGB, essentially making the RGB image
more "grey". Using BPC is enabled by default.
With black point compensation
Without black point compensation
Format:Format describes the image file format. You may choose between these 4 formats:
jpeg
- A good general purpose format supported by most applications. JPEG
offers efficient compression by removing \"hard to see\" details from
the image.
eps - Encapsulated PostScript files used for page layout by graphics arts professionals.
pdf
- PDF files can be viewed on most systems using the Adobe Acrobat
Reader and can also be used for page layout by graphics arts
professionals.
tiff - A good general purpose format
supported by most applications. Because TIFF supports lossless
compression it is a good starting point if you need to work on the
image in an image editing application like Adobe Photoshop.
Rotate:The Rotate function lets you rotate the image. Rotation is
measured in degrees. Click in another input field or hit the tab key on
your keyboard to update the preview after you have entered a new value.
Here are some examples of rotation:
Width, Height:Specify
the width and height of the image in pixels. You don't need to specify
both. If for example you only specify width, eRez will adjust the
height accordingly and constrain proportions.
If
you specify both, width and height, the selection will be locked to the
aspect ratio given by the width and height value. Press SHIFT while
resizing the selection to ignore the aspect ratio. Note: If your
Browser does not support Flash the aspect ratio will not be locked.
DPI:Specifies
the DPI (Dots per Inch) associated with the image. Changing this value
does not affect the number of pixels in the image or the size of the
file. It is merely used to describe the physical dimensions of the
image when placed in a page layout application or similar.
Crop top,left:You
can use the cropper handles in the image displayed to select minor
parts of it. You can also set the numbers manually for a left crop,
that is from the top left corner. The number specified is the x,y
values (top value, left value). The range of the values goes from 0 to
1 so that:
Crop top,left: , actually means crop 10% from left and 10% from the top
Crop bottom,right:Similar
to the crop mentioned above, but here you crop from the bottom right
corner. The values 1,1 means that the bottom right corner goes to 100%
button and 100% right of the image.
Filename prefix, postfix:A
prefix is a text string added before the filename and a postfix is a
text string added after the filename (but not the file extension). This
feature is useful for discriminating between different variations of
downloaded images.
Example: The postfix ”_300_DPI” will change the filename car.tiff to car_300_DPI.tiff.
If you download several variations of the same image, but with
different specifications, you can use this feature to distinguish
between downloads of the same source image with different
specifications.

How to open ZIP files
In
order to minimize the time it takes to transfer the image and to avoid
that your browser tries to display the file instead of saving it, the
image files are always compressed and delivered as ZIP files.
Some
operating systems such as Mac OS X and Windows XP come with the
software necessary to open and extract images from ZIP files. Users of
other earlier of Microsoft Windows can use the WinZIP utility and Macintosh users can use StuffIt to open the files.
Download Original
Downloads
the original image file to your computer. Please notice that eRez first
packs the image into a zip file. When that process is finished eRez
tells you: Your image is ready! and prompts you for a place on your
computer to download the image to.
