struct PCXheader
{
        char pcxID;
        char version;
        char rleEncoding;
        char bitsPerPixel;
        int x1,y1;		
        int x2,y2;
        int hRes;
        int vRes;
        unsigned char palette[48];
        char reserved;
        char colorPlanes;
        int bytesPerLine;
        int paletteType;
        char unused[58];
};

  width = x2- x1 +1;
  height = y2 - y1 +1;

  I can send you the rest of my source code if you need it.  Now if
someone has a jpeg reader, that's impressive <grin>.  

  I wonder if anyone out there knows the structure to windows font
files... I've been looking for them for awhile now.
