Content-Aware Slicing A source sprite sheet on a transparent background, before any cuts, with the sprites sitting at uneven spacing rather than on a regular grid. https://imagemint.net/assets/images/tutorials/example_1_after.webp Individual Sprites After Content-Aware Slicing The same sheet after slicing, each sprite extracted as its own file and trimmed to its own bounding box, so the files differ in size where the original cells did not line up. https://imagemint.net/assets/images/tutorials/example_2_fisrt_after.webp Detection Sensitivity Set Too Low A slicing run that produced far fewer files than the sheet contains, because neighbouring sprites were treated as one — the signature of a sensitivity setting that is too low. https://imagemint.net/assets/images/tutorials/example_2_second_after.webp The Same Sheet With Sensitivity Raised The same region re-sliced with higher detection sensitivity, separating the sprites that had previously been grouped into a single file. https://imagemint.net/creative 2026-08-13 https://imagemint.net/og-image.jpg ImageMint Creative Applications Use cases for the ImageMint tools: extracting sprites from a sheet, cutting a tileset, cleaning up flat backgrounds, packing a CSS sprite sheet, sizing images for Instagram and Open Graph, upscaling pixel art without blurring, and moving between PDF and image formats. https://imagemint.net/tutorials/slice-uneven-ai-sprite-sheet 2026-08-13 https://imagemint.net/assets/images/tutorials/sample-sheet-uneven.webp Uneven AI-Generated
