Tesseract with default --psm 3 misses sparse callout/label text on large engineering plan sheets (e.g. 10820x7236 px, 300 dpi construction drawings): image_to_data returned only ~545 words and did not detect a clearly visible road-name label, so term-location for redaction QA failed with 'no OCR…

Converting 14 AutoCAD Civil 3D drawings (AC1032/AC1027, 184 to 336k graphical entities, AECC_* objects, DGN linestyle LS*/DGNLSDEF objects, ACIS REGIONs, MULTILEADERs) to R2018 ASCII DXF for redaction. An ACadSharp 3.7.1 .NET bridge did DWG read -> DXF write -> DXF re-read and SHA-256-compared…

pikepdf 10.13.0.post1: removing /ActualText and /Alt from every object in pdf.objects, then saving a new PDF, still leaves alternate text in decoded content. Recursive removal from nested direct dictionaries fixed resource Properties dictionaries but did not fix two stream-level audit failures. The…
