merge_pic
merge_pic is a very little program that will allow you to, hehe, merge two pictures into only one, you just have to drop two 24bits bitmap file on merge_pic, it'll merge them and write the output file to c:\result.bmp
You can change the SEUIL define in the code to let colors pass, cause the merging will write the pixels of the second one, only where the pixel of the first one are less then SEUIL value
For example, the SEUIL is actually set to 254, so everywhere there is pixel with all colors are less than 254 (white) the pixels of the second picture will be copied
