coetool is a cli or gui program to convert from .coe files (memory map for a ROM in an FPGA) to image files and the other way around, load an image and generate .coe file. Original author: http://jqm.io/files/coetool/
changed some places to fit my requirements：convert an image to .coe file in RGB888, not the original RGB332.
