Now let’s make it a little bit less pixelated. It’s not a cure-all method, but blurring it up a little with a bilinear filter helps a lot…
Then I apply the code below which applies a cool colormap to the pixel values. I’ll provide cleaner code for this later (I have a really cool way of generating colormaps and saving them as arrays of RGB tuples). Then I go through and plot some random sin wavs on top of it. Sweet! Here are 6 images generated from the program run 6 times. Notice the randomness of the sine wavs!
__A different image is generated every time the script runs, __and it requires no external files (bitmaps or fonts) and should work well on all operating systems.
