Well assuming that int is 4 bytes, and each pixel takes 3 bytes, then the pixel data is all confused, and you have more work to extract the information.

Here's what 4 pixels looks like spread over 3 int's.
RR GG BB RR : GG BB RR GG : BB RR GG BB


If you have a buff of 240000 chars, and not 80000 ints, then you might get somewhere.

But then, is the raw file 240000 bytes or 320000 bytes?
Because that would tell you whether it used 4-byte pixels with every 4th byte being zero.
