; Pic-2-Data by Prof - Include images in your source as DATA statements
;
; Only use for small images like sprites / icons etc.
;
; WARNING! - Even though this program converts each pixel and stores it
; as a shortened Hex ARGB value, (i.e. $0000FF00 is stored as $FF00),
; the file size can still be very large.
;
; The program also gives you an option to save the decoder in the
; source code as well.
