Pure Python bitmap decoder/encoder

This is just a little bitmap encoder/decoder I wrote to get a better understanding of the bitmap file format.

This is pretty inefficient but gets the job done. It can read and write bitmap files.

Current functionality:

• Read images
• Write images
• Convert to grayscale
• Center crop

Examples

import bmp
bitmap = bmp.BitmapReader('frame.bmp')
bitmap.grayscale()
bitmap.write('frame_gray.bmp')
