alfresco-simple-ocr error on macOS

ebrenessdev

Hello,

I have installed the addon alfresco-simple-ocr by keensoft and all its dependencies (ocrmypdf, tesseract, imagemagick). When I tried to OCR a pdf it throws me this error

Exception in thread "defaultAsyncAction1" java.lang.RuntimeException: java.lang.RuntimeException: org.alfresco.service.cmr.repository.ContentIOException: 01190024 Failed to perform OCR transformation:

If I tried to run the next command manually in my terminal it works without any issue

/usr/local/bin/ocrmypdf --verbose 1 --force-ocr -l spa+eng+fra --output-type pdf /Users/erickbrenes/Documents/dev/alfresco526/alfresco/tomcat/temp/Alfresco/OCRTransformWorker_source_7618353995588703757.pdf /Users/erickbrenes/Documents/dev/alfresco526/alfresco/tomcat/temp/Alfresco/OCRTransformWorker_source_7618353995588703757_ocr.pdf

does this addon works on macOS?

The log above point to this file

I have fixed this issue, I had to add the correct image magick properties in alfresco-global.properties

### ImageMagick Config ###
img.root=/usr/local/Cellar/imagemagick/7.0.9-23
#  ----> I had this property wrong, 'img.dyn' <----
img.dyn=${img.root}/lib
img.exe=${img.root}/bin/convert
img.gslib=/usr/local/Cellar/ghostscript/9.50/lib
#img.coders=${img.root}/modules/coders
#img.config=${img.root}/config

#GS executable
ghostscript.exe=gs

#Tesseract executable
tesseract.exe=tesseract

# OCRmyPDF

# running 'which ocrmypdf' returns '/usr/local/bin/ocrmypdf', I think this value could be used as well

I'd suggest you to use the dockerized version that can be produced with:
