optimization of images with /Metadata or /SMask references #136

Closed rbrito closed 1 year ago

rbrito commented 4 years ago

Hi, @pts.

First of all, this is a different bug from #133, despite having similar symptoms.

I just discovered that if a CCITT image has a dictionary with a /Metadata key in it, then pdfsizeopt doesn't optimize such image.

I'm attaching here some PDF files that show this issue. If you could help with this, it would be awesome.

Thanks,

Rogério Brito.

I just discovered the issue with pdfsizeopt skipping those images (the metadata was indirect and pdfsizeopt was skipping anything with an indirect information after doing the basics with images).

I wrote a fix to this situation here: https://github.com/rbrito/pdfsizeopt/commit/a742cf286c77ec8ed2902f01c000417f74a35531

If you would like me to send a pull request, please let me know (this would be my first contribution to pdfsizeopt).

Thanks,

Rogério Brito.
