Summary0007602: Image downsampling on PDF export may be wrong when the same image is used several times
Descriptionsee "Steps To Reproduce"
Steps To ReproduceCreate an image frame and insert a picture; set the resolution to a high value (e.g. 1000 dpi). Then create a second image frame and insert *the same picture*; set the resolution to a low value (e.g. 100 dpi).
Export as PDF, setting Maximum Image Resolution to, say, 150 dpi.
The PDF exporter will resample the image based on the first occurrence, but still use the same XObject for the second occurrence of the image. This results in the first image frame being exported as 150 dpi, the second one however has only 15 dpi ( = 150 / 1000 * 100 ).
TagsNo tags attached.

Well, what's the problem? Maximum image resolution is really 150dpi ;)
Confirmed!

Don't make me file a second issue with swapped frame creation order :-)

On a side note: Why not crop the image to the maximally needed rectangle (at least when resampling it anyway)? That would decrease file sizes.

Currently the way we read and write images does not allow to do that easily. We have already discussed about doing that, that will come at a point.
