Different strategies for loading images in my Zatnik image format; the project lets you choose a method (which I may add more of at some point), load and render an image code, and see how long the loading took. For more info about Zatnik images (including other Scratch projects that use them, as well as a web page that can convert PNG images to Zatnik images), you can go here: https://arctenik.github.io/zatnik-images/
I only recently noticed that this project, which can work with Zatnik images, existed: https://scratch.mit.edu/projects/383699069/ ....and since I saw it was using my scripts for loading them, and that those scripts can be *really* slow for images of the size that that project uses, I decided that it would be cool to try and improve the loading speed. Turns out you can use costumes to map characters to numbers, and get constant-time access to pixel colors, instead of the linear time you get by searching through the list of colors to find the one that matches.
