Thanks, I’m glad the tool is useful.
I don’t think I properly understood your question though. I’ll try answering it anyways:
If you are talking about the before/after animations, these are videos I created and rendered as GIFs. I can add the ability to export images as such animations to SLK_img2pixel if needed.
If you are talking about exporting upscaled versions of the output images, that’s currently not possible, but I can add that.
If you are talking about creating images larger than 256x256, that’s possible by selecting the relative tab in the general section. By using this, the image gets divided by the factor specified.
If I completely missed the meaning of your question, please try to rephrase it. I’m trying to provide the best user experience possible and good feedback is the basis for that. :)
