I created a Visual Studio Code extension that allows doing simple matrix manipulations on text. As you might have already guessed, this is really useful to manipulate images that are represented as text in makecode:
- Install this vscode extension: https://marketplace.visualstudio.com/items?itemName=ractive.textmatrix
- Then go to the javascript view in your project and copy the image as text
- paste it into vscode and perform one of the supported operations (like " Rotate text by 90 degrees")
- copy the modified text in vscode and paste it into makecode again
See here how this will look like: https://imgur.com/a/QTjgIzz
