Re: [sane-devel] Scan quality enhancements/processing (vs Windows with Fujitsu ScanSnap S1500)

I'm not sure on this question, but for semi-auto cropping, you'll likely need 
to 
perform something to the similar, for which I (obviously) haven't yet mastered:

# Acquire scanned image
$ scanimage --format=tiff --resolution=300 > /tmp/receipt.tif

# Two likely incorrect incantation of ImageMagick convert for cropping an image.
$ convert -trim -fuzz 55% /tmp/receipt.tif /tmp/receipt-cropped.tif

$ convert -verbose -border 10x10 -trim +repage -fuzz 75% /tmp/receipt.tiff 
/tmp/receipt-cropped.tiff

# OCR the tiff file
$ tesseract /tmp/receipt-cropped.tiff /tmp/receipt.pdf

# Search multiple PDF files for TEXT
$ find /tmp -name '*.pdf' -exec sh -c 'pdftotext "{}" - | grep --with-filename 
--label="{}" --color "SOME_TEXT_HERE"' \;


As you can see, I was performing something similar to what you're doing, but 
then had to migrate to other tasks due to a lack of time.

Had I completed the above, one would have to admit, the above steps would be 
far more quickly performed rather than relying upon even the best of today's 
GUI tools directly due to the load time of the GUI.

Re: [sane-devel] [janitorial] CI now builds snapshots with "funny" versions

[Olaf Meeuwissen]

Hi All,

I found it most unfair that sane-frontends didn't get the same snapshot
tarball treatment as sane-backends does so I set up a simple CI job over
on GitLab.com.  All it does is roll a source tarball.  Nothing more.  It
doesn't even try to compile the sources.  But!  We now have a

  sane-frontends-1.0.14-31-gc1b7785-dirty.tar.gz

on http://sane-project.org/snapshots/

Now I'm wondering if I should drop the daily git archives ...
# ... and update the SANE - Download web page[1].
# [1]: http://sane-project.org/source.html

For those of you running cron jobs against those git archives, perhaps
now is your chance to speak your mind (or change your cron job ;-)

Re: [sane-devel] Where is the define of SANE_I18N

[DanTan]

Hi Olaf,

I got it.
Thank you for your explain.

Hey guys,

I have working on the source code of sane-backends, I found the macro
SANE_I18N is used to sane’s localization. But I just found the follow
lines of it’s define

#ifndef SANE_I18N
#define SANE_I18N(text) text
#endif

The above lines, dose nothing. So I wonder how SANE_I18N translate
these backends?

The backends don't translate.  It's the responsibility of the *frontend*
to translate the strings.  The SANE_I18N macro is only the marker we use
to tell xgettext which strings should be translated.  These strings end
up in po/sane-backends.pot.

The reasoning behind making the frontend responsible for translation is
that the backend may be executing remotely (e.g. via saned).  You don't
want to get the translations suitable for a remotely executing process.
This process may execute under a different LANG setting than your local
SANE frontend.

Let's say you run your frontend with LANG=zh_CN and scan via the net
backend on a server that just happens to run saned with LANG=fr_FR.
Would you be happy with French messages?  Probably not ;-)

Hope this helps,
