![]() ![]() You can create a sticker effect by putting a stroked white outline around each element. The result of marching squares is an array of x/y coordinates that form the outside outline of the element You can again use the “marching squares” algorithm to do edge detection. ![]() Also erase that discrete element from the main canvas (so it's not processed again).ĭetect the outline-path of each discrete element. Put each discrete element on its own canvas for further processing. You can find discrete pixel groups using an edge detection algorithm like "marching squares". For example, each individual sprite on a spritesheet would be a discrete element. Start by drawing your original image to the main canvas.ĭecompose the image into “discrete elements”.ĭiscrete elements consist of groups of pixels that are connected to each other but not connected to other elementss. ![]() Here's one way to add a "sticker effect" on your image. ![]()
