images are not reduced in PDF export

[Michal Hlavaty]

If I put some high-resolution images in my drawing and then save as PDF. Inkscape doesn't reduce the resolution of these images (according to Resolution for rasterization (dpi)), but instead of that, it puts image in its native resolution, so PDF file is needlessly large. Method of inserting image (link, embed) doesn't affect this issue.

It's necessary to count image resolution manually and link resized image. Size of PDF was reduced from 20 to 3 MB at 300DPI in my drawing.

The dpi export option only affects the rasterization of objects styled with SVG filter effects [1], not embedded or linked bitmap images.

Yes, it's duplicate of Bug #246677.

Thanks for link, but [1] is useless for me. Images in my drawings don't have any filtres.

Bug #171774 I am not sure.
Bug #672135 yes.

Sorry for duplicate.
