Resizing the image leads to a raster artifact across the entire image. If you look closely, you should see it in the screenshot. If I just convert to png (or jpg for that matter) without resizing, the artifacts don't appear so I believe it has to do with the resizing. ``` $ git rev-parse HEAD 86e82282664169dfaa004a85ac5bc75c2bc95c40 $ cargo run -- ~/Pictures/372CANON/IMG_9863.JPG -resize 3240x2160 ~/Downloads/raster.jpg ``` <img width="859" height="622" alt="Image" src="https://github.com/user-attachments/assets/bac9707c-8529-4740-baba-4844b848f7bf" /> This doesn't happen with `magick`. ``` $ magick ~/Pictures/372CANON/IMG_9863.JPG -resize 3240x2160 ~/Downloads/raster-magick.jpg ``` <img width="371" height="405" alt="Image" src="https://github.com/user-attachments/assets/cc666f45-d1eb-4881-889e-002376d2f3f8" />
