Distribute a slide show on a CD

PolyView slide shows can easily be distributed on a CD so that they can be viewed on a machine that does not have PolyView installed. The following paragraphs describe the operations you must perform to prepare the CD slide show for distribution.

Create a relative slide show script

The important thing to remember about running a CD slide show on another person's computer is that the drive letter on the CD may be different from that on which the CD was originally prepared. For this reason PolyView provides a method to create a slide show script with file names that are not dependent on an absolute drive letter but instead depend only on the locations of the files relative to the slide show script file (.PVS file) that calls them out.

To save a slide show script with relative file naming, click the Save button on the Slide Show Creation Window, then choose PVS-Relative Script from the Save as type list before naming and saving the script file.

Add your images and script to the CD

If you create a relative slide show script on your computer's hard drive and then transfer it and the associated image files to a CD it is important that the locations on the CD correspond to the original locations on the hard drive. As an example consider the case where the slide show script is stored in C:\Pictures and all the image files are stored in C:\Pictures\Vacation. One possible storage setup on a CD would be to store the slide show script in the root folder of the CD, and the image files in a subfolder of the root folder named Vacation.

Add PolyView to the CD

In accordance with the PolyView License Agreement, you can place PolyView on your CD and distribute it to an unlimited number of users as long as the PolyView distribution files are included on the CD. This includes all the following files:

inetwh32.dll
License.txt
PolyView.cnt
PolyView.exe
PolyView.hlp
PolyImagePro.dll
Readme.txt
Roboex32.dll

Make an "autostart" CD

You can make a CD that automatically plays a slide show by including a file named autorun.inf in its base folder. This file must contain the instruction for starting PolyView, including the path to the slide show script that is to be run.

The contents of an autorun.inf file look something like:

[autorun]
OPEN=

For example, suppose you have created a CD with polyview.exe stored in a folder named PolyView, and your image files and a script named the_show.pvs stored in the root folder. Your autorun.inf file should then contain the following two lines:

[autorun]
OPEN=.\PolyView\polyview.exe .\the_show.pvs

PolyView does not have to be installed on the end user's machine for this to work - it will run correctly from the CD. Be sure, however, to store the slide show script as a Relative script.

Frequently Asked Questions - PolyView

Why do some images appear distorted when I view them?
There are a number of graphics cards whose drivers have problems with some of the high performance bit block transfer routines that PolyView uses to display images. The visible symptom of this problem can be seen as image areas that are painted with random colors. This is a particular problem when large images are being "shrunk" to fit within the available display space. PolyView supports a lower performance technique that solves this problem in many instances. The Limit Transfer Size option on the General tab of the Properties dialog (Options menu) forces PolyView to use this lower performance technique. You may notice some degradation in panning and scrolling speed with this option selected.
Why do the JPEG files I downloaded from the AOL browser not open in PolyView?
America OnLine uses a proprietary compression scheme when it downloads images from the Internet. When this compression is turned on it renders the image unreadable by nearly all image viewers. If you turn it off through the WWW preferences in the Member Preferences area of the AOL program, images will be downloaded in industry standard formats.
