COREL PROFESSIONAL PHOTOS CD-ROM
UNIX INSTALLATION GUIDE
PHOTOS CD-ROM SCREEN SAVER FOR SOLARIS.
This chapter describes how to install the Corel Professional Photos Screen
Saver application and provides details about how to use the Screen Saver.
INSTALLING THE SCREEN SAVER.
1. Insert the Corel Professional Photos disk into your CD-ROM drive.
2. If the CD-ROM is not mounted automatically, please mount it at the
unix prompt.
*** If you have problems mounting the CD-ROM, please contact your ***
*** local system administrator. ***
3. Create an install directory on your hard disk to which the Corel
Screen Saver binaries will be copied. Please ensure that you have
read/write access and at least 55 Megs of free disk space.
i.e. Syntax: mkdir <install_dir>
4. CD into that directory.
5. From the <install_dir>, run the "ss_inst" executable found on the
CD_ROM in order to install the Corel Screen Saver. Please note
that the "ss_inst" file is situated in a subdirectory called unix.
i.e. Syntax: #/<cdrom_mount_point>/unix/ss_inst
6. The install program will then prompt you for the cdrom installation
directory. Please specify the "/<cdrom_mount_point>/unix". The
install program will then proceed to tar off the required files into
your current directory. The installation program should report a
successful installation.
7. Once the installation is complete, you can remove the "sstar" file
which was copied to the <install_dir> directory. This file is not
required to run the screen saver and by removing it, you will free
up disk space.
8. There are two variables to set prior to running the Corel Screen
Saver: the PATH and the LD_LIBRARY_PATH.
Please append the "<install_dir>/bin" directory to your current PATH.
i.e. Syntax: #setenv path=($path <install_dir>/bin)
(for C-shell)
Please append the "<install_dir>/lib" directory to your current
shared libraries path.
i.e. Syntax: #setenv LD_LIBRARY_PATH=($LD_LIBRARY_PATH <install_dir>/lib)
(for C-shell)
*** For other shells, please contact your local system administrator. ***
You may then proceed to configuring your screen saver.
USING THE COREL SCREEN SAVER FOR SOLARIS
The Corel Screen Saver application is a two process set of applications.
There is a configuration application that allows a user to create a screen
saver configuration file, and a runtime application that uses the
configuration file and displays a number of images that consume the entire
desktop screen.
The configuration application is written using the Motif toolkit for X
windows servers. The runtime application is written in the Kodak Photo CD
access tookit and X11 intrinsics. The runtime application does not currently
have password protection, to this end the Corel Screen Saver will not secure
your workstation from other users.
If you choose to include sound files with your screen saver configuration;
remember that the Solaris version of Corel Screen Saver will only deal with
Sun audio sound files. Refer to the man pages for audiotool(1) for more
information.
Due to the runtime processing of Kodak Photo CD images the following rules
of thumb should be considered when choosing a runtime screen saver
configuration:
Each Screen Saver image is approximately 1200 by 1100 pixels wide.
Each pixel is configured with 8 bits of colour.
Each image is converted into an X11 compatible image using the Kodak
Photo CD access toolkit. Therefore, each image will permanently
consume a large amount of memory while the runtime application is
alive.
If you are using an X terminal or a diskless workstation then the runtime
application will use a server somewhere on the network to service swap space.
If your configuration uses many images then the applications' data will be
swapped between the server and the desktop that is using the Corel Screen
saver application.
The Photo CD images are read once from the CD-ROM that contains their files.
For as long as the runtime application is alive there is no need to retain
the CD-ROM disk in the CD-ROM drive. If for some reason the screen saver
runtime application stops the CD-ROM disk must be in the Caddy when it
restarts, especially if the computer is an X terminal or diskless workstation.
Each time a Photo CD image is read and transformed into an X image the size
of your workstation display the time required to perform the operation is
approximately 5 minutes per image. This time is considerable due to the
fact that the image resides on the CD-ROM in one resolution( 512 by 256
pixels ) and has to be transformed to an image to fit the desktop screen
height and width.
The sizes and times should be taken into consideration when initiating a
runtime instance of the screen saver and deciding which images you would
like in your screen saver configuration.
The screen saver configuration application's main screen is invoked by
running the corel_config_app executable found in the <install_dir>/bin
directory. There are 4 items on the application menu bar. The first is
the 'File' option menu. The second is the 'View" option menu. The third
is the 'Option' option menu. The fourth is the 'Help' option menu.
The 'File' option menu contains these items:
New: Allows the user to start a new screen saver configuration.
The user is prompted for information in two stages. The first
stage is to prompt the user for a file name that will contain
the runtime screen saver information. The second stage is to
prompt the user for the location of screen saver files.
The image file selection dialogue is a standard Motif File
Selection Dialogue. The Filter directory name is the user's
path when the configuration application was started. The user
can double click on items in the directory list box to change
the Filter directory selection. When the Filter selection area
contains the name of the of the appropriate directory the user
may begin selecting file names from the File Item list.
Selections can occur by double clicking on file name of selecting
the file with a single mouse click and pressing the 'Ok' button
of the dialogue box. Each selected file will be copied to a list
box behind the selection dialogue as a reminder of which image
files where selected. When the file selection is completed,
please click on the cancel button. At this point, both
dialogue boxes will disappear and your current settings will be
written to your configuration file. If you wish to further
customize your screen saver settings, please see "Options"
menu below.
Open:Allows a current configuration to opened and it's images to be
viewed. The user is prompted for the configuration file name in
the same manner as above.
Save:Allows a configuration to be saved using the name specified in
the New configuration file dialogue.
Save As:Allows for a different file name to be used than that which
was specified in the New configuration file dialogue.
Exit: Will exit the application.
The 'View' menu has three items called: 1) 'Configuration'. 2) Page Up.
3) Page Down .When image files have been selected this option may be
instituted to view the images found in the image file selection list.
They are shown large enough for the user to judge if the image is
appropriate or not( this is larger than thumbnail size as some darker
photos tend to look almost black in a thumbnail resolution ). Page Up
an be used to scroll through images in the configuration in the up
direction. Page Down can be used to scroll through images in the
configuration in the down direction( these configuration images may not
fit on the screen depending on the number of images in the configuration.
If there are more images than can fit on the screen the Page Up and Page
Down actions scroll through the list of images in the configuration ).
The 'Option' menu contains 4 items. 1) Delay Time. 2) Change Rate
3)Sound Repitition. 4) Scale The Delay time is specified in minutes
and controls the amount of time the screen saver remains inactive,
monitoring the desktop, before starting. The change rate is the rate at
which multiple images are switched between each other. Sound Repitiion
will repeat the sound files <Repitition> times before stopping. The Scale
option allows for the images to be reduced in size during runtime if the
default image size is larger than your monitor size.
The 'Help' menu contains items to display text about various functions or
attributes of the screen saver configuration application.
The screen saver application name is: 'corel_config_app' and can be found
in $<install_dir>/bin.
The runtime application is named corel_ss and takes one typed parameter: -f.
The file name to supply as the argument to -f is the name of the
configuration file specified in the configuration utility.
If you are running on a machine( X terminal, diskless workstation ) you may
experience problems with the runtime application. In the event of an error
specifying a resource problem or problems dealing with the Kodak Photo CD
toolkit, remove one or more images from your configuration file. You can
use your favourite editor to delete the lines of image file names at your
discretion.
