I need to draw visible lines on pictures with wxPython. That means I can't simply use, for instance, a black line since it wont be visible on a black or dark picture.
Painting applications like the GIMP accomplish this by altering the colour of the line based on the colour of the pixel it covers, but the only way I can think of doing that is getting each pixel, transforming the colour then painting it on the screen, which seems like a horribly inefficient way do it. I could use alternating colour on the lines, but I don't think that will be good enough for my taste. I think I will use a partially transparent bitmap with a hole in the appropriate place and move the hole as needed. I realized the last solution as I was writing this and I think it will work fairly well, but I'm still wondering if there is another, better solution i might have missed. /Odalrick -- http://mail.python.org/mailman/listinfo/python-list
