Hi I'm using grx23 with djgpp and all goes fine but, with linux, I meet a problem The problem is that GrSetColor don't seem to work : - we define 1024x768x256 mode => pseudo color in 8 bits - next we set the colors : for (i=0;i<256;i++) GrSetColr(i,i,i,i); : we should have a gray-level color table from black (i=0) to white (i=255) but when I display an image of the gray-levels, I obtain colored colors (green red,blue yellow...) Can someone tell me what to do to obtain my gray-level color table using THIS WAY Thanks
