circle_crop

act imperative

Crop one raster into a circular transparent PNG in the browser. Pass image { mime, base64 } (max 12 MiB decoded). size is the output square edge (16–4096, default 512). zoom 1–8 and offsetX/offsetY pan in output pixels; omitted zoom/offsets mean cover-centered. Variant URLs are not a second machine Tool — pass size explicitly for discord (512) or twitter (400). Do not upload.
