Most of the programs worked and almost all with the patches, still some problems with xcursor and xkey.
You should modify your program to work with real RGB color values instead of a color lookuptable:
First call
GrSetRGBcolorMode();and use
GrColor GrBuildRGBcolorT(int r,int g,int b); GrColor GrBuildRGBcolorR(int r,int g,int b); /* ...R Limits r,g,b to 0..255; ...T doesnŽt */
or
GrColor GrAllocColor(int r,int g,int b);
to calculate the color value from rgb values.
Hope this helps,
Yes, thanks. I was able to modify my old DOS programs to work under Linux When I compile, I still have a warning that I can't get rid of:
passing arg 4 of `GrBuildPixmap' from incompatible pointer type
GrColor color_tab[256]; // initialize color_tab GrBuildPixmap(pixels,w,h,color_tab);
should work. (Note: untested !)
whatever I give as the type of the color table (GrColorTableP, long, unsigned long...) but it seems to work.
Thanks again.
