There's a better version of this project! https://scratch.mit.edu/projects/163440219/ You can still use this one, and the images from this project are fully compatible with the new version, but the new version is less buggy and has more features, so I'd recommend using it! - Turbo mode (shift+click the green flag) is recommended. - Press.... • N for a new image (an image with width greater than 78 and/or height greater than 52 won't work!) • Click the color circle to change the color • Click a variable's label to change the variable • C to switch to color picker • P to switch to paintbrush • B to switch to bucket fill • H to hide the saved image or color selector • S to save an image code, which can be used to load the image back into this project (double-click the text to select it, then copy it somewhere) • L to load an image from an image code • X to save as an XPM image, which can be loaded by some other programs, but not by this project. When you press X, it will give you some text. You may not be able to see all of it. If you can't, click on it, then do Control+A, or Command+A on a Mac, to select all of it. Then copy it into a plain text file and change the extension to .xpm. • O to save as BBCode. Copy this the same way that you'd copy an XPM (see above), and then you can use post it in the forums. (On this thread, maybe: http://scratch.mit.edu/discuss/topic/82194/) NOTE: Bigger images won't work as BBCode, because of the character limit on the "join" block. I'll have to add a slightly more complicated way of saving bigger images...
I have some pages about the image format used in this project at https://zatnik.github.io/zatnik-images/ Also maybe check out https://scratch.mit.edu/projects/158350887/ where you can turn 16x16 images from this project into Minecraft-style blocks The equation for turning RGB values into a pen color was made by JTxt, and the RGB to HSV conversion came from rapidtables.com.
