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.

I'm closing this due to lack of response, assuming that updating
ImageMagick fixed things. Please reopen if you can still reproduce it.
