I used Ephesoft Community Edition and there are Tesseract 3.01 but only eng files.
I need to find tessdata for French Language but impossible to find it.
I tried to used 3.02 tessdata files but tesseract crashed.
Thank you in advance for your answer.
The language packs for the old versions can be found at https://sourceforge.net/projects/tesseract-ocr-alt/files/.

First of all, I have to make clear that I need the zip version because I will use it on Win 64 in the business and there we have no admin privileges on notebook.
I looked out over web but I wasn't able to find where I can get the VSCode v1.25(.1). I only found .EXE versions or source code archive.
Why I need this? VSCode 1.26 and greater (and many others electron based applications) are very slow in Win 64. Thank God I use Linux at home! Please, see this issue: https://github.com/microsoft/vscode-docs/issues/4609
Ok, after report it as an issue on github vscode repository, somebody gave me the provisory link and previous archives (zip) versions will be put available asap issue come to be solved.
VSCode 1.25.1 archive (zip) Win64 link: https://vscode-update.azurewebsites.net/1.25.1/win32-x64-archive/stable
Go to https://code.visualstudio.com/docs/supporting/faq#_previous-release-versions.
The URLs to each download are provided there.
I am new to tesseract and am a bit confused with the different directories in the github page.
The tesserac-ocr code base is what I installed. That installed a tessdata directory in /usr/local/share/tessdata/
So now while training tesseract I run the following command -
# tesseract img.tif img box.train
I get the following error
Tesseract Open Source OCR Engine v3.03 with Leptonica
Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
Could not initialize tesseract.
Obviously its not able to find the tessdata folder.
So now I obtained the tessdata directory from github (https://github.com/tesseract-ocr/tessdata). Then pointed the TESSDATA_PREFIX to the downloaded tessdata from github. Does not change anything. I get the following error -
Tesseract Open Source OCR Engine v3.03 with Leptonica
read_params_file: Can't open box.train
So my question is what should the tessdata be pointed to? Where does tesseract obtain the box.train from in the training command?
One of most stupid things you can do as novice is try to train tesseract ;-)
Next: 3.03 version is not in official github.com repo (btw: 3.03 was never official released... it was just Ubuntu that made that release.)
Next: if you installed tesseract correctly (from source) box.train is installed. You you installed from Ubuntu packages/repo (I do not think so, because in that case tesseract would not used /usr/local/... ) than you should contact packager how (s)he packaged tesseract.
I was trying to add PNG support to my Emacs installation to display png files. Though I found the following and some other links online, I'm still not able to view png files.
Emacs under Windows and PNG files
I have copied libpng and zlib1 dll files in my emacs/bin directory and have made sure that they are not outdated but the
(image-type-available-p 'png)
returns nil. I would like to know if I'm missing something.
I am using Emacs 24.4 on Windows 8.1 64-bit.
Any help is appreciated. Thanks.
From https://ftp.gnu.org/gnu/emacs/windows/
Emacs can also support some other image formats with appropriate libraries. These libraries are all available on the following sites:
http://sourceforge.net/projects/ezwinports/files/
-- leaner, more up-to-date builds, only for 32-bit Emacs
http://www.gtk.org/download/win32.php
http://www.gtk.org/download/win64.php
-- the GTK project site; offers much fatter builds, but includes
64-bit DLLs (from the 2nd URL)
Can anyone please help me in finding the mongofiles.exe for windows 32bit because it is missing from my bin folder. for 64 bit it is there but its showing compatibilty issues. Please help

I have a question regarding the tesseract training.
I am currently using Tess4J in order to integrate tesseract within my java program.
Reading on the tesseract wiki page on tesseract training (http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3), one is able to train tesseract using training images with various combinations and fonts.
Is it possible for me to have just a "normal" tesseract 3.02 (windows or unix) installation constructing these lang.traineddata files, and afterwards just include this in my tessdata folder utilized by my Tess4J wrapper from my java program. Or is the Tess4J limitied to the included language data for English, and sample images that are bundled with the program?
If so, is it possible to include these in to my Tess4J build in some other way?
As it is just a wrapper of Tesseract OCR engine, it accepts any standard issue or custom traineddata files. You can find the standard traineddata at https://github.com/tesseract-ocr/tessdata.
