Reveal Image of the Masking

[mnse]

Hi @Judy,.

There are several ways to do what you want …

Made also a masking example for another topic…

Painting/revealing a layer

Hi @bringmeflowers, better use the mask function for this … check out… PGraphics maskimg; PImage underlyingimg; void setup() { size(800,800,P2D); underlyingimg = loadImage("image.jpg"); // create mask (should be same as the underlying image size) maskimg = createGraphics(underlyingimg.width,underlyingimg.height,P2D); // initialize the whole mask with black (everything hidden) maskimg.beginDraw(); maskimg.background(0); maskimg.noStroke(); maskimg.fill(255); maskimg.endDr…

Try both a mask and a pixel version. It’s fun and a good exercise.

Cheers
