strokewidthtransform container craches using PDF and "stroke-width-transform" #127

Open cbleek opened 4 years ago

cbleek commented 4 years ago

convert-pdf still not work.

I've started the container via run.sh un ubuntu 18.04

Executing the following leads to a crashing strokewidthtransform_1 container.

cbleek@xenon:~$ curl -X POST -H "Content-Type: application/json" -d '{"img_url":"https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf","engine":"tesseract", "preprocessors":["stroke-width-transform"]}' http://ocr.cross-solution.de:9292/ocr
