(In reply to Telesto from comment #20)
In case the user changes the resolution, this resolution has to be written to
the image. In case the user does not touch that field, the image should not
change in that respect, which means would still be empty for the "cat"-image.

> Save image
> 1. Right click an image -> Save -> Choose file name & PNG & Press save
> 2. PNG options dialog popups up.. also having an resolution setting
> 3. Save the file -> open it with Irfan view -> DPI Resolution isn't written
I can confirm that. Please write a bug report. It works in Draw, if you use
File>Export instead.

> Compress image
> 1. Right click an image & choose compress
> 2. Pick a resolution: 300 DPI and an image size
> 3. Press compress
> 4. Save the file
> 5. Rename the ODT to zip & and extract the image
> 6. A DPI resolution is written.. but not my pick. 72 x 71 (really 71) DPI
I can confirm that. Please write a bug report.

There might be an error in the way LibreOffice has implemented "crop". I will
look, how it is specified in the standard.
