Can not ocr pdf files as input #167

Closed FadeFx closed 1 year ago

FadeFx commented 1 year ago

Hi, i was playing a while ad could not find out what is my issue, workflow_ocr did not seem to work. My only trigger was a collaborative tag (ocrme). However, when I tried to use a file created and mimetype pdf i found out that pdf was not allowed, so i created a jpg from one pdf and added my tag. That moment my server began to ocr the file and saved it as a pdf. My question is, why is it not possible to handle PFD files? Am I holding it wrong? ;-)

What do you mean by "PDF was not allowed"? Aren't you able to setup a workflow like described here: https://github.com/R0Wi/workflow_ocr#trigger-ocr-if-file-was-created-or-updated ?

Yes, i can set it up, but if I tag a pdf file it will not be processed, however jpg files will be. If I try to add a filter for specific mime type pdf i can not save the workflow the save button turns orange saying the configuration is invalid and an additional error message that the regular expression is invalid Screenshot_20221204-202117_1

Sorry screenshot is German and from phone...

Could be you're hiting https://github.com/nextcloud/server/issues/23666#issuecomment-785647870. Please try "is" instead of "matches" before the mimetype PDF setting

That works and now pdfs get ocr'd thank you... Strange that it did not do this without any mime type filter ...

Glad to help. Hope this will be fixed in NC workflowengine soon 👍
