I removed the restriction with the command

sudo sed -i 's/rights="none" pattern="PDF"/rights="read|write" pattern="PDF"/g' /etc/ImageMagick-6/policy.xml

but know the image is blank [43]. Also the convert doesn't work if the density is not given.

    const pdfImage = new PDFImage(file, {
      combinedImage: true,
      convertOptions: {
        '-resize': '200x200',
        '-quality': '75',
        '-density': '800',
      },
    });

I am also having this issue. Any luck?

This isn't an issue with this tool, rather an issue with the environment where it's being run.

As far as the image being blank, i would need a replicable test case to investigate.

[VassilisPallas]

It runs inside a docker image which is using ubuntu as base image. The pdf file is just a file inside /tmp. I have already provided to you the code I'm using. In saveTemp you can use fs to store the file.

[toddself]

Sorry, the code above does not run, nor is there a Dockerfile to build it. If you'd like help with this, I'd be happy to help, but I need a fully replicable test case first.

sudo sed -i 's/rights="none" pattern="PDF"/rights="read|write" pattern="PDF"/g' /etc/ImageMagick-6/policy.xml

This fixed my problem, thanks alot
