Hello people, I'm writing a Bitmap parser for study purposes, however when I parse a bitmap file and when I paint that file in a window, the script take to much time.
1. You turned constants into static methods called for every line, adding attribute lookup and function call time. 2. You read the image a line at a time and break each line into separate pixel objects.
3. You paint each pixel by drawing and filling a 1-pixel rectangle.
How can I optimize my script loops to be faster ?
Don't do any of the above. Look at how other programs such as PIL or pygame read, store, and paint images.
