Another "convert: no images defined" error

[Nutria]

Hi,

Code: Select all

$ convert output.pdf foo.jpg
convert: not authorized `output.pdf' @ error/constitute.c/ReadImage/412.
convert: no images defined `foo.jpg' @ error/convert.c/ConvertImageCommand/3210.

Code: Select all

$ convert -version

$ gs --version

This is Xubuntu 16.04.

https://www.imagemagick.org/discourse-s ... hp?t=32267 seems to be a similar problem, and a respondent asks if ghostscript is installed. I do have gs installed.

Is there some other library that I'm missing?

Thanks.

Always read the first error message.

not authorized `output.pdf'

That means you are not authorized to rasterize PDF files. I suggest you edit your policy.xml.

Thanks. Based on one of the comments, in /etc/ImageMagick-6/policy.xml I changed this:

<policy domain="coder" rights="none" pattern="PS" />
<policy domain="coder" rights="none" pattern="EPS" />
<policy domain="coder" rights="none" pattern="PDF" />
<policy domain="coder" rights="none" pattern="XPS" />

to this:

<policy domain="coder" rights="read|write" pattern="PS" />
<policy domain="coder" rights="read|write" pattern="EPS" />
<policy domain="coder" rights="read|write" pattern="PDF" />
<policy domain="coder" rights="read|write" pattern="XPS" />

That should be correct.
