Compression? artifacts

[charlie59876]

padding and unpadding isn't perfect and often leaves some kind of artifacts. padding once etc isn't too bad but if you repeatedly pad and unpad multiple times which i do to test things the image can degrade more and more

You should use always the original source file for processing. If you add padding, then export, then remove padding, then export artifacts can happen if you use JPEG for example. Never do that!

Use a source file for work. You should always save your changes to that file, and that file should use a pixel precise save method (PNG, PSD, XCF and so on). When you want to use it in your level, export it to PNG, then do the padding.

i made a file with the artifacts shown, they were much worse but i fixed them up. sadly i don't have the original image with the artifacts sorry. the right image the tiles overlap as well
