To the site administrator: This file and GraphicsWorkshop.tar should
replace the previos version, GraphicsWorkshop.tar.Z. PS. sorry about
the number of copies, but after the number of install complaints, I
felt this version warranted a new copy. It should also go into the
2.0 sources directory.
This program is a set of generic tools for loading and saveing bitmaps in
various forms. It has a simple program for demonstrating the features of the
object. Currently, the objects are under going Beta testing and should be final
sometime in mid spring. At this time, the protocol spoken is not stabalized,
so if you wish to program with the objects at this time, expect that some-
things could change between now and final release, however, things will
likely remain the same.
The bitmaps support are the following:
Type Long Name Reading Writing Multiple
--------- ------------------------------------- ------- ------- --------
gif(1)(2) Graphics Interchange Format Y Y N
jpg Joint Photographic Extention Group Y N N
pbm Portable Bitmap Y Y N
pgm Portable Graymap Y Y N
ppm Portable Pixmap Y Y N
tiff Tagging Image File Format Y Y Y
xbm X11 Bitmap Y Y N
(1) Gif does not handle gif89a files, and may not work with some custom
header extensions.
(2) Be careful when saving to gif, since it requires color quantitization, you
may experience color banding. Saving works best on images with losts of
colors.
Installing:
Installing is easier than ever. Take the following steps:
o untar the package, tar -xvf GraphicsWorkshop.tar
o Double click on the appropiate package.
o GraphicsWorkshop.pkg is the main executable
o Converters.pkg are the converters
o GRSource is all the source.
o Have fun and report bugs to alex@data.ACS.CalPoly.EDU.
Note: you need the first two to run the program, you can delete
the last if you're not interesting in programming converters
or playing with the source.
PS: To previous users, the install script is still there, and you
can still use it, but the above method should be easier.
If things don't work, and you have the developement enviroment, try building
everything in debug mode, so you can send me a snap shot of the console
window. This will help me find the problem quickly and easily. If you can't
compile, just try and send me the best description you can of the problem.
Also, if the problem involves a particular bitmap, please NeXTmail be that
bitmap along with the problem description. (Don't worry about picture
content, I'm not easily offended.) Anyways, I can be reached at the address
below.
