Picsel Image File Format Support

BMP 

Windows Bitmap (BMP) is a format used by MS Windows and other 
programs which value simplicity over economy. BMP files are almost 

always uncompressed and so very large. 
 

BMP can include 1, 4, 8 or 24 bits per pixel, allowing both indexed and 
full colour. Neither transparency nor animation are supported.
