a1e3150bd7 Add new parameter "document_title" to set the title in OCR output files 
The title can be set for hOCR and PDF output.

Currently it is also used for ALTO, so setting the title can be used
as a workaround for issue #2700.

The constant unknown_title_ is no longer needed and therefore removed.

Merge pull request #2686 from stweil/boxfilename 
Extend function BoxFileName to handle more common image names
 2019-10-05 16:53:34 +02:00
Stefan Weil
7a7704bc94 Extend function BoxFileName to handle more common image names 
The function derives the file name for the .box file from an image name.

For training from existing line images, it is useful to directly support
the image names which are commonly used.

While generated images for Tesseract training typically use the name
pattern NAME.tif, other ground truth sets use NAME.bin.png for binarized
or NAME.nrm.png for grayscale images.

BoxFileName is also now a local function as it is only used locally.

1e84a6f225 Don't create OCR result files when training data is created 
The configuration file lstm.train causes Tesseract to generate
training data for training of an LSTM line recognizer.

In this mode, no other files with OCR results should be written.
Without this patch, Tesseract writes a small text file.
