- or if requested oversamples the images before OCRing so as to get
better results
- When possible, inserts OCR information as a "lossless" operation without transcoding
images or rendering vector information

New features
------------
- Lossless reconstruction: when possible, OCRmyPDF will inject text layers without transcoding
images or otherwise manipulating the content and layout of a PDF page. The overall PDF is still reconstructed.
- Lossless reconstruction: when possible, OCRmyPDF will inject text layers without
otherwise manipulating the content and layout of a PDF page. For example, a PDF containing a mix
of vector and raster content would see the vector content preserved. Images may still be transcoded
during PDF/A conversion. (``--deskew`` and ``--clean-final`` disable this mode, necessarily.)
- New argument ``--tesseract-pagesegmode`` allows you to pass page segmentation arguments to Tesseract OCR.
This helps for two column text and other situations that confuse Tesseract.
- Added a new "polyglot" version of the Docker image, that generates Tesseract with all languages packs installed,
for the polyglots among us. It is much larger.
Changes
-------
- JPEG transcoding quality is now 95 instead of the default 75. Bigger file sizes for less degradation.
