[Inkscape-user] Export as PDF with embedded bitmap: resoltion of export in dpi not used, JPEG exported a PNG?

Hi,

I want to use some bitmaps (PNG or JPEG file) in Inkscape.

If I export the file as PDF and set a resolution in DPI it is ignored. I can change it to 2 dpi and the image still look the same and the file size also does not change.

If I use a JPEG file as import bitmap the file size rises. It seem that it is saved as PNG in the exported PDF file.

Can you help me with a proper pdf export that reuses the imported file type and the resolution in the export file dialogue.

TIA Martin
