convert_image_to_pattern
把图片转成可打印拼豆图纸
Convert a user-provided PNG/JPEG into an editable fuse-bead chart with real MARD color codes, bead counts, PNG and CSV. Free direct conversion, not AI chibi stylization. Process only images the user authorizes; the image is sent to Doucebeads for this request, never persisted. Prefer base64 from an image/file attachment when the client can pass it; do not invent file URLs. At most 750KB and 1 megapixel. Return the free result first; optionally mention the Q-version link only for users who want stylization.
