Unable to process pdfs - Windows

[fraserpage]

I'm seeing the following on Windows 10. You assistance would be greatly appreciated.

Syntax Warning: Bad annotation destination
Syntax Warning: Bad annotation destination

I see about 30 lines of the above when using trying to process a pdf with pypdfocr filename.pdf.
I see the below with any usage.

Hi @fraserpage

I've had the same issue. In my case, the code for parsing the version string used by tesseract does not work as intended by the author. In particular, my version string was 3.05.00dev which caused the same error as you when the script tried to parse it and determine whether it was correct.

As a workaround, you can add the following bold lines to the file pypdfocr_tesseract.py found in python27\Lib\site-packages\pypdfocr:

for line in ret_output.splitlines():
            if 'tesseract' in line:
                ver_str = line.split(' ')[1]
                **if ver_str.endswith('dev'):
                    ver_str = ver_str[:-3]**

Hope this helps,

Florian

Thanks very much @flothesof! That got it working for me.

I'm still seeing the warning about imagemagick. Any clues on that one?

Hey there!

The warning is normal, the program is just telling us it would like to do
some additional checks before adding ocr. I've found no problems with the
default resolution while using it.

Best regards
Florian

Got it. Thanks for your help!

Going to reopen and fix this in source for next release. Thanks for pointing this out, folks!

Hi - can the exe be fixed with this same patch?

@flothesof: The warning message is actually not normal, but is reporting an error on Windows. This has been fixed in #54

I'm still running into this problem with the word alpha in Version 0.9.1
My added fix for this (based on flothesof's answer):

checkFileEndings = ['dev', 'alpha']
for line in ret_output.splitlines():
    if 'tesseract' in line:
        ver_str = line.split(' ')[1]
        for fileEnding in checkFileEndings:
            if ver_str.endswith(fileEnding):
                ver_str = ver_str[:-len(fileEnding)]
