convert: Option '-resample' requires an argument or argument is malformed

[tonyblue2]

Hello,

please excuse my bad english - but I am not a native Speaker.

I installed pmOCR on a Ubuntu 20.04.4 LTS. But if I try to start it in batch-mode I got the error Message "convert: Option '-resample' requires an argument or argument is malformed.".

These were my Steps:

I added the /etc/pmocr/default.conf

What is wrong?

Thank you

Hello Tony,

I found that I mistyped some arguments for the intermediary PDF transformation which is required to make searchable PDFs from existing ones.
In the meantime, I re-evaluated those arguments in order to make quicker preprocessing.
I've updated current master. Could you give it a spin ?

Please update your default.conf with the one on git too.
Don't forget to tweak the settings in default.conf for your language (guess -l deu ?) and other options. The optional image preprocessor for tesseract is quite CPU hungry, but needed if your scans are skewed / noisy.
speeding up can be achieved by lowering resolution to your scanner resolution (I leave 600dpi as default in order to never loose quality, but most people don't scan with 600dpi).

Mfg.

Hello deajan,

thank you for your message and your help.

I rolled back my machine und installed it again.

No I got this errormessage:

Well that's bad, looks like the command line for imagemagick isn't recognized on your system.
Can you give me the output of convert --version ?
On my test machine I got the following which works well

[tonyblue2]

I saw that you installed "ImageMagick 6.9.10-86 Q16". I have installed GraphicsMagick 1.3.35 2020-02-23 Q16.

So Now I tried to install

apt-get install -f imagemagick-6.q16

So now it looks like your post:

I looked for a solution for the "not allowed" an found: https://forum.ubuntuusers.de/topic/imagemagick-funktioniert-nicht-2/

in

[deajan]

Hell I hate distro compile differences. I'll have to spin up an Ubuntu to check that. I'll report back.
In the meantime, could you remove the 'sharpen' argument in default.conf for testing ?

[deajan]

Well, I actually made a mistake placing the -compress lzw argument.
Made another commit that should fix the conversion arguments, among a couple of other improvements.
Can you update both pmocr.sh and default.conf from current master and try again ?

[deajan]

@tonyblue2 Can you confirm that pmOCR works on your system now ?

So far so good, it seems that the intermediary transformation is fixed, but the tesseract OCR engine isn't working.
Would you mind checking for more output in /var/log/pmOCR_MyOCRServer.log ?
If no more output is in that log file, could you run with export _DEBUG=true before running your command ?

[deajan]

@tonyblue2 Would you mind posting the logs?
