In sample.tex, the option "azure" in the line:
\documentclass[pdf,azure,slideColor,colorBG]{prosper}
loads Prosper's azure style. Replacing that line with:
\documentclass[pdf,gyom,slideColor,colorBG]{prosper}
and keeping everything else the same, will load the gyom style and produce the following slide:
Compare this with the previous output and note the drastic changes, including the fancy "bullets" in the itemized list, brought about by the change of a single keyword!
The following standard Prosper styles are available. I have provided sample images for those styles which I think are more interesting than others. Also see the gallery for a wider variety of samples.
Experiment to see which one is more to your liking.
\documentclass[pdf,alcatel-fixed,slideColor,colorBG]{prosper}
In addition to the standard styles listed above, a few locally defined styles files are also available. These are named umbc1, umbc2, umbc3, umbc4. You can use these just as you would use the standard styles. For example:
\documentclass[pdf,umbc3,slideColor,colorBG]{prosper}
results in the following slide:
/usr/local/TeX/inputs/prosper
Files in that directory whose names begin with PPR, are Prosper style files. The gyom style, for instance, is defined in the file PPRgyom.sty.
Locally-defined UMBC style files are in the directory
/usr/local/TeX/inputs/prosper-umbc
If you have a department account, you don't need to do anything special to use the UMBC styles -- they are already installed. If you don't have a department account, you can download the UMBC style files and use them in the same way that you would use Prosper's own style files.
The options slideColor, slideBW, colorBG, nocolorBG, have no effect on UMBC styles.
