bmpinfo = bmp.GetInfo() bmpInt = bmp.GetBitmapBits(False)
GetBitmapBits(False) returns an integer for each R G and B value of each pixel. So:
14, 16, 17, -1
represents R:14, G:16, B:17, and -1 for the alpha channel. The negative numbers are actually offsets from 255, so -112 above would be equivalent to 255 - 112, or 143.
