Re: Image Formats

[Evan Marchant <evan@achaia.dircon.co.uk>]

What about, 
char * buf; /* If buf points to vd mem */
FILE * pout;
int ctr;

fout=fopen("bitmap.raw", "wb");

for(ctr=0;ctr<(320*200);c++)
{
	fwrite( (buf+ctr), 1, sizeof(char), fout );
	//Can't remeber exeact order of params */
}

fclose(fout);

file, is that it doesn't include anything like the resolution of the file,
and colors, and everything, it automatically assumes that it's 320x200x256
and uses a predetermined palette (which I already created in a file called
'palette.dat', and written a routine to set it up). All it should contain
is the exact data that should be sent to the video card. The first byte of
the file should be the start of the video memory at a000:0000. If anybody
knows of a better way to do this, I would appreciate it.

since I no almost nothing about bitmaps - except that you can use GIMP to
create them, etc. :-)
