Mouse to draw. Space to erase all, R for random color. Anti-aliasing set to 1 is normal pen. Setting it to 0 is the cool part! Let me explain: Normally, if you draw a line on a grid of pixels and only paint with the EXACT color you are drawing with, the line will have harsh jagged edges because of the pixel edges. This is aliasing. Scratch usually smooths out these edges by fading between your color and transparent along the line's edge. This is called anti-aliasing, because it gets rid of the harsh jagged edges for the most part. Disabling anti-aliasing causes the lines to be aliased again; with harsh jagged edges. Unfortunately this project doesn’t support transparency, but that’s probably fine if you’re using it for technical reasons. (Subtle foreshadowing...)
