Package: gscan2pdf Version: 0.9.25-1 Severity: important
When I import a tiff file created by scanimage, it can be "OCRised" by tesseract. But if I crop the image (it's necessary with multi-columns text), I got the next message in the console from where I've loaded gscan2pdf: Tesseract Open Source OCR Engine check_legal_image_size:Error:Only 1,2,4,5,6,8 bpp are supported:16 *** unhandled exception in callback: *** Error: cannot open /tmp/NLA9Ssq5aV/DWUea9s5Xc.txt *** ignoring at /usr/bin/gscan2pdf line 1114. The same cropped image saved as a tiff file gives such information with tiffinfo: g...@fantasio:~$ tiffinfo texte3.tif TIFF Directory at offset 0xec7f8 (968696) Image Width: 961 Image Length: 504 Resolution: 300, 300 pixels/inch Position: 0.01, 1.04333 Bits/Sample: 16 Compression Scheme: None Photometric Interpretation: min-is-black FillOrder: msb-to-lsb Orientation: row 0 top, col 0 lhs Samples/Pixel: 1 Rows/Strip: 4 Planar Configuration: single image plane DocumentName: /tmp/NLA9Ssq5aV/8SVdkwLXUI.tif ImageDescription: SANE data follows Of course, she can't be treated by tesseract separatly. The choice of a mode of compression (of none) doesn't affect tesseract. Once cropped, the image can't be treated by unpaper. Error message on the console: Avertissement : Format d'image non reconnu at /usr/bin/gscan2pdf line 1394. *** unhandled exception in callback: *** `' is not of type Gtk2::Gdk::Pixbuf at /usr/share/perl5/Gtk2/Ex/Simple /TiedCommon.pm line 65. *** ignoring at /usr/bin/gscan2pdf line 1114. I've not tested other features of gscan2pdf, my needs was only to find a simple guy to proceed the OCR with tesseract.
