PDF files are read by PDFBox library. You may want to look into that area 
as well.

[tesseract-ocr] Re: Tess4j failing near load of shared library tesseract-ocr-5.2 in Java 11 and 17, succeeds in Java 8

[Quan Nguyen]

The source of tess4j is available; you can trace through the code to see 
what threw the exception.

Nevertheless, "throwable while reading PDF" seems to point to the part of 
code that reads in PDF file. Was that something you wrote, or from tess4j 
itself?

Re: [tesseract-ocr] Re: ErrorInInitializerError - zip file closed out of tess4j.util.LoadLibs.getTesseractLibName

[Quan Nguyen]

You try the suggested program to see if the same exception occurs. If it 
does not, then it's possible that something in your code is not right. 
VietOCR is open source; you can browse through the code to see how it works.

Another suggestion: try to use the alternate Tesseract1 API.

[tesseract-ocr] Re: how to combine (merge) trained data of Tesseract files

[Quan Nguyen]

Merging two traindeddata files is not possible nor supported. What you can 
do is rename your custom language pack to, say, eng1.traindeddata and then 
specify -l eng+eng1 when running the tesseract executable.

[Quan Nguyen]

Not about training, but you should use the latest version of tess4j that 
corresponds to the latest Tesseract releases.

https://github.com/nguyenq/tess4j

Hope it will produce better results for you.

The command line imposes a limit on the command length. You can group 
images of same fonts in a multi-page TIFF to cut down the number of files 
and then conduct training on it.

I don't think Tesseract supports this. You may want to try to generate a

You may need to scale the image to 300 DPI for better results. This is 
especially true for screenshots, where the resolution is typically at 72 or 
96 DPI.

It looks like the datapath is set incorrectly. It should be set to tessdata

[tesseract-ocr] Re: Missing Characters

[Quan Nguyen]

It looks like Times New Romon font does not have the glyphs for the

Btw, that application is jTessBoxEditor, not VietOCR.

I tested your sample image and confirmed the error. It looks like a bug in

[tesseract-ocr] Re: Tesseract API to output PDF with txt layer

[Quan Nguyen]

Yes, the PDF functionality is exposed in C-API 
 
interface, which Tess4J  fully 
supports.

[tesseract-ocr] Re: java.lang.UnsatisfiedLinkError in tess4j

I've found the unit tests completed successfully with JDK 10 as well. So 
make sure you install the appropriate VC++ runtime.

That was old posts for older versions. You need VC++ 2015 at this time.

Btw, we haven't tested it with Java 10 yet. Will do that soon.

You need a much larger sample, in the range of hundreds or at least several 
dozens, so that even though some symbols could experience "Couldn't find a 
matching blob" errors, other samples would get picked up.

[Quan Nguyen]

The error message indicated Tesseract was looking for osa.traineddata file 
under C:\Program Files (x86)\Tesseract-OCR folder. You need to correctly 
specify the path to tessdata folder. Your oem value seems to be incorrect 
too.

Run at the command prompt for full instructions:

[tesseract-ocr] Re: Error in executing new .traineddata file

[Quan Nguyen]

Sounds like you've trained using Tesseract 3.05, so it could run with 
Tesseract of that version or newer and is not backward compatible with 
older version 3.02.

[tesseract-ocr] Re: How can JTessBoxEditor generate lstm files ?

[Quan Nguyen]

As of today, it supports only legacy training (i.e., 3.0x version).

Training for 4.0x is described in the Training Wiki 
.

[tesseract-ocr] Re: Tesseract max pages while ocring?

[Quan Nguyen]

The GhostScript-based PDF module in Tess4J sets the limit to 999 since it 
was thought that the users would never attempt to go beyond that since 
loading only a few hundreds of 300-DPI full-size image pages into memory 
would already cause out-of-memory exceptions.

It depends on your needs. There are also fast traineddata:

It looks that many languages are represented.

[tesseract-ocr] Re: Tesseract on Bitmap images giving error - Error: "Failed to create pix, this normally occurs because...

[Quan Nguyen]

Leptonica provides many different methods for creating Pix object. You can 
read from file, memory buffer, etc. So you may need to write your bitmap to 
such intermediate formats and read back as Pix.

pixRead
pixReadMem
pixReadMemPng

Check its API doc:

[tesseract-ocr] Re: use jTesseractEdit training but box edit is empty

[Quan Nguyen]

I don't see any box file, but from the appearance of the image, Tesseract 
probably had problems recognizing it, therefore, producing an empty box 
file. You'll need to perform some image processing first to make the image 
more amenable to Tesseract.

Either merge them into a single multi-page TIFF before sending to Tesseract

jTessBoxEditor 2.0 beta versions bundle the latest Tesseract 4.00alpha 
training executable. The training process for 4.00, however, has not been 
integrated to the program. The 3.0x training process is still supported.

Check out the two videos that depict the 3.0x training process:

You can try download the source and compile. Then
