output pdf

[fiddlededee]

Thank you for the project. Stable and fast. The only problem is, I needed to have pdf, not png. So, I came to this solution.

pdf-diff before.pdf after.pdf | docker run -i dpokidov/imagemagick png:- -crop 294:207 -border 1x%  +repage pdf:- > comparison_output.pdf

or without docker

pdf-diff before.pdf after.pdf | convert png:- -crop 294:207 -border 1x%  +repage pdf:- > comparison_output.pdf

The rationale for docker is that relative crop is supported only in ImageMagic 7x.
