Is it possible to set the bleed and trim box values?

Please be more specific about what you request.

Hi Josch,

Currently we can set the pagesize e.g.

img2pdf --pagesize 1224.57ptx875.91pt ...

We are preparing files to go to print and need to specify the trim box and bleed box. It would be really handy to be able to pass these on the command line as well - maybe something like:

img2pdf --pagesize 1224.57ptx875.91pt bleedbox "top,left,width,height" trimbox "top,left,width,height" ...

An examaple output that we'd get from one of our pfds with everything set correctly:

Ah cool! Could you send me an example document implementing that?

I added the correct boxes using podofobox

I was not ware of the podofo tools. Thanks!

I'm wondering how to best implement this feature.

I don't like the idea to let the user freely specify these boxes because img2pdf is supposed to be just for the use-case of converting images to pdf and not a fully fledged pdf editor. If one wants to set the boxes precisely, then there is podofobox.

So I'm thinking about implementing this feature in the same way as the --border option was implemented. So instead of giving all four corners, one just gives the relative horizontal and vertical distance between the MediaBox. This would then also play nice with images of different sizes where each pdf page would have a different size.

Would that satisfy your use-case or do you need precise control of each coordinate of the boxes? If yes, why?

By Chris G on 2019-03-09T09:15:58.389Z

That would definitely satisfy my use case and would be ideal.

I'm sure there will be people out there who do need to control each coordinate, but I can't think of any obvious reason to do that and as you say if that's what you want then using podofobox is probably the right solution.

Mentioned in issue #61

Hi, could you test the version from git? Commit ed6187d5 should implement the feature you need. Try using the new --crop-border, --bleed-border, --trim-border and --art-border options.

This should be fixed in version 0.3.4
