Release ScanTailor OCR 1.0.6 · 2ndmax/scantailor-ocr

What's new

The panel "PDF compression" has a part for each kind of page: color and grayscale, posterized pages, and black and white.
JPEG 2000 for color, grayscale and posterized pages: better looking pictures at the same size, or smaller files at the same quality. At quality 100 it is lossless.
Lossless choices for every kind of page (Deflate, or no compression).
Replacing an existing PDF is always confirmed first.

New panel "TIFF compression" at the bottom of the Output step (moved from the settings window), built like the PDF compression: color and grayscale, posterized pages (new, separate setting), and black and white.
New: JPEG quality, and LZMA for the smallest lossless files (slow, and read by few other programs; ScanTailor OCR and its PDF export read it).
Smaller files without a setting: grayscale and color pages use the horizontal predictor with LZW, Deflate and LZMA, and posterized pages with up to 16 colors are stored with 4 bits per pixel.
After processing, the Output step shows the written file, so losses from JPEG are visible right away.

Each panel holds what its "Apply To ..." button applies; its parts have bold headings instead of nested collapsible boxes.
Split Pages: the page type is switched with Auto / Manual buttons in the panel. The apply dialog offers "Page type" and "Split line".
Output: resolution and dewarping are set directly in the panel.
All apply dialogs offer the same choices of pages and have distinct titles.

Changing the source DPI in the Margins panel takes effect right away (before, only after switching steps).
Thumbnails are updated again when their path is longer than 260 characters, as with pages renamed by the automatic import.
