Functionsยง

encode_debug_image
generate_marked_image
Convert a GrayImage to a Base64 JPEG with a quadrilateral and optional anchors drawn on it. If transform is provided, anchors are projected from template space (relative to width=100) to image space.
to_png_bytes
warp_perspective
Apply perspective transform to the entire image. Maps src_img to a destination image of size width x height using the transform pt (which maps Src -> Dst). We iterate Dst pixels, map backwards to Src using transform_inverse (coeff_inv), and sample.
