The image has no 'size' without DPI. So crop is broken when switching between resolutions. So only a message won't solve the problem. And the original size would still be 'random' depending on screen DPI. Will talking about DPI: 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 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</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
