Hi,

Using 6.3.9 CE version

I am seeing multiple tesseract errors in log:

2021-01-21 13:23:34,850 [Thread-16] [] WARN  com.openkm.util.ExecutionUtils - Abnormal program termination: 1
2021-01-21 13:23:34,850 [Thread-16] [] WARN  com.openkm.util.ExecutionUtils - CommandLine: [C:\Program, Files\Tesseract-OCR\tesseract.exe, C:\tomcat-8.5.34\temp\okm2629366693785316603-0009.pbm, C:\tomcat-8.5.34\temp\okm7056446360890699995]

Error in findFileFormatStream: truncated file
Error in fopenReadStream: file not found
Error in pixRead: image file not found: P4
Image file P4 cannot be read!
Error during processing.

When I look at the .pbm files under temp, they just have 1KB of size and if I open them with notepad the content is:
P4
1 1

Any suggestions / ideas?

Thanks,
Felipe.

I suggest using stable version either alpha ( tesseract version 4.X maybe is a bug ).

Also I suggest check tesseract directly from terminal, usually in this manner maybe you'll get more information about what's happening.

Thanks,

So you don't think is the process that generates that .pbm file?
is that file supposed to be a text file or a graphics file...I thought pbm stands for portable bit map?

First step should be discover what document is raising this issue. Then using Administration > Tools > Check text extraction can execute the process manually to debug what happens. At the end the objective is trying to reproduce from the command line.

If it is a PDF file, maybe the images into have some issue. Or a local library with a bug what raises this exception with these images.
