Ok this is what is happening. The library works now which is awsome.
When I create the bitmap through just grabbing it through
wingetbitmap() function I get a nicely sized image but the colors are
messed at 320x320.
Then if I create the bitmap through using wincreatebitmapwindow()
function, creating a window wrapper around the bitmap, then copying
the screen over using wincopyrectangle I get a smaller image with all
the right colours. I try creating the bitmap with higher height and
width but that does not change the size of the image. The size of
these images are 160x160. I have tried using a version3 bitmap and
changing the density but that doesn't seem to change anything.
Any ideas?
