dm_read — SYMBOL datacode2d op

使い方

画像から Data Matrix を読む: 位置決め → 標本化 → 復号、明暗を反転して再試行(table)。

Read a symbol from a grey image: locate + sample + decode, retrying on the inverted image (light-on-dark marks) — inverted reports which succeeded. The result holds every key of :func:dm_decode_modules plus homography (for the normalised grid), reflectance (normalised orientation), threshold, corners, module_px, locate_score, inverted, angle_deg (direction of the module +x axis in the image, degrees, atan2(d_row, d_col)) and image_mirrored (the symbol appears mirrored).
