@todd-richmond, you are talking about orientation detection: 0 / 90 / 180 / 270 degrees. @Balearica is talking about [a page with some parts that are skewed](https://tesseract-ocr.github.io/tessdoc/ImproveQuality.html#rotation--deskewing)

@Balearica, Did you try using `AnalyseLayout()`? https://github.com/tesseract-ocr/tesseract/blob/bf7c134ba6958f2efdaace2fbeba31cad91394ce/include/tesseract/baseapi.h#L433-L449

The training tools for the legacy OCR engine were broken since version 5.0. They were fixed recently. Try the latest code in the main branch of this repo, or wait...

The problem is that we don't know if there might be some cases where this patch will cause worst results. @stweil, @zdenop, maybe we can accept this addition if it...

We don't plan to support the HEIC format.
