1. GIF89a and licence (to Mike and others)

Hi Mike (and whom this might interest),
I checked the license problem you pointed to at CompuServe. Under:

http://websearch.cs.com/cs/results/cssearch-frameset.adp?type=I&first=1&dfirst=1&sTerm=GIF87a&type=I&brand=CSI&tabs=Y&serviceType=CServe&uType=5049181&dateRange=0&channel=&gfirst=0&hit_url=http%3a%2f%2fwww%2edanbbs%2edk%2f%7edino%2fwhirlgif%2fgif87%2ehtml&rUrl=http%3a%2f%2fwww%2edanbbs%2edk%2f%7edino%2fwhirlgif%2fgif87%2ehtml

I found the following remarkable sentence:

The Graphics Interchange Format(c) is the copyright property of
CompuServe Incorporated. Only CompuServe Incorporated is authorized to
define, redefine,
enhance, alter, modify or change in any way the definition of the
format. 

CompuServe Incorporated hereby grants a limited, non-exclusive,
royalty-free license for the use of the Graphics Interchange Format(sm)
in computer software;
computer software utilizing GIF(sm) must acknowledge ownership of the
Graphics Interchange Format and its Service Mark by CompuServe
Incorporated, in User
and Technical Documentation. Computer software utilizing GIF, which is
distributed or may be distributed without User or Technical
Documentation must display to
the screen or printer a message acknowledging ownership of the Graphics
Interchange Format and the Service Mark by CompuServe Incorporated; in
this case, the
acknowledgement may be displayed in an opening screen or leading banner,
or a closing screen or trailing banner. A message such as the following
may be used: 

    "The Graphics Interchange Format(c) is the Copyright property of
    CompuServe Incorporated. GIF(sm) is a Service Mark property of
    CompuServe Incorporated."

Do I understand this right? What is your opinion?

Have a nice day, Rolf

Hi Brian,

thanks for pointing to the PNG format. But 

1. there is no legal restriction to use the GIF format, and
2. there is the 'save_pic.zip' package from Christopher Street in
   the Euphoria archive which seem to contain just those routines
   I need.

Although ''save_pic.zip' is declared to be for DOS32, the routines I
need will run under Win32. The enhanced capabilities of PNG format is
not really useful for my demands, and there is no EUphoria library for
PNG right now.

Thanks again, and have a nice day, Rolf
