Please disregard my question below. I've determined that the source was from a problem with my image in memory. It turned out that I wasn't readjusting for the image size and hence, was missing a few lines.

I have an image in memory (decoded as a 160 x120 pixel image) and using the following sequence to display it. It appears that the data is being interpreted as a 32 bit instead of 16 resulting in a larget image with visible horizontal lines.
Anyone have any idea how to fix this?
GrArea(pmap, c_gc, 0, 0, 160, 120, (void *)c_data, MWPF_TRUECOLOR555);
GrCopyArea(c_image, c_gc, 0, 0, 160, 120, pmap, 0, 0, MWROP_USE_GC_MODE);
c_data is actually a u16 * (unsigned short).
Thanks.
