Support for tesseract 5.4 #2241

Closed aberenguel closed 3 weeks ago

aberenguel commented 3 weeks ago

I've upgraded the tesseract of my machine (Detected tesseract version 5.4.0-rc2-17-g3469).

When testing with maven, some tests failed (output log set to ERROR):

I think it is a bug in tesseract. Running the command in shell:

Estimating resolution as 234

Just reverted tesseract to version 5.3.4. Now it is working again.
