Dear all,
I open a bmp device by the bmp() function in the png package, but I
don't know how to write color pixel by pixel into the file? Any help or hint?
What I want to do is to create a 512*512 bmp file with certain dots
being red and others black. I have all the pixel coordinates for the red dots,
but I don't know how to draw the color on the device.
Please help me!
Sincerely yours,
Yingqi
