My picture was refused. What do the messages mean?
- "No clear shape in this picture: it needs one dark shape on a light background.": the picture is too faint, or has no single dark shape. Use a black silhouette on white.
- "This looks like a line drawing or a very thin shape: a maze needs a solid, filled silhouette.": an outline drawing has no inside for the paths. Fill the shape, or draw it with AI.
- "The shape is too long and narrow to hold a maze: choose a rounder subject.": a pencil, a snake or a sword seen from the side is too thin.
- "The shape is too thin and spread out to hold a maze: choose a chunkier subject.": a spider or a tree with bare branches leaves too little room.
- "That picture could not be read. Try a PNG or JPEG.": save it again as PNG or JPEG.
- "Choose a PNG, JPEG, WebP or SVG picture." or "That picture is larger than 15 MB: choose a smaller one.": convert or shrink the file (phone photos in HEIC must be converted to JPEG first).
