Hi there!

I think have a small problem with my pcx decoding routine or with
dosmemput(). Since the picture looks like being rasterized heavily.

First: my doublebuffer is defined like this

unsigned char *doublebuffer = (unsigned char *)malloc(320*200);

i hope its ok. Then the decoding code is like this: i have a feeling the
error is here but i cant find out what it is. Thanks to anyone who has the
time to help me out. By the way while im at it, is .bmp file encoded with
RLE as .pcx image is?.  I know that .tga doesnt seem to be at least thats
what the tutorials  i've read say..

Thanks alot everyone!
Peter.

int total_bytes,total,totalb; /* should this be long? */
unsigned long count,data; */ or char ? */
totalb = image.width * image.heigth (1 image.ymax - image.ymin);

while(count<=totalb)
{
 data = getc(Data);
 if(data>=192 && data<=255)
  {
  total_bytes = data-192;
  data = getc(Data);
  while(total_bytes-->0)
   {
   doublebuffer[count++] = data;
   }
 }
 else
  {
  doublebuffer[count++] = data;
  }
}
