Howdy Rastislav, Howdy List,

thank you very much for the nice feedback. Hearing stuff like that is 
very motivating.

i was very busy the last couple of days :). Not sure if you know, there 
was a small tool named OCRPDF born out of the OCRdesktop code. its for 
quick OCR Image and PDF files. this broke as well. So i decide to 
reunion the code bases. I also did a lot of improvements and cleanups 
while doing that.
you can now OCR files like images, PDFs (also with multiple pages) with 
OCRdesktop. For this, its also quite optional now having a UI. because 
OCRdesktop can pipe the result to STDOUT.

See here for the complete story:

there is also some goodie information about OCR the clipboard content in 
my blog you might be interested in.

if you like my work you can support me on patreon if you want 8).

i have some other ideas i wanna bring in next couple of weeks:

- multiprocessing for OCR PDF files for performance speedup
- something essential as a loading bar while OCR process (lol)
- i have an idea for a while, tesseract creates some noise when OCR 
widgets. i.e. a checkbox is detected as a Q. i want to suggest this 
common pattern at details page.

i would say, we set then OCRdesktop on steroids 8-), i will return to 
migrate Orca to an plugin driven architecture.

cheers chrys
