Created attachment 155620 [details] Optimize Images Presets If you would like to compress images in LibO the default settings are: compress single image --------------------- JPEG Quality: 90 PNG Compression: 9 Resolution: 96 DPI If you use the default settings for Presentation minimizer the default settings are: Impress minimize ----------------- JPEG Quality: 75 Resolution: 150 DPI Gimp Defaults JPEG Quality: 90 PNG Quality: 6 Krita Defaults JPEG Quality: 80 PNG Quality: 7 Compress single Image ===================== was used in writer, calc, ... everywhere the goal should be the print, cause if it work on print, it will work on the screen to. -> JPEG Quality: 90 don't compress them very much -> PNG Compression: 9 mean no compression at all -> Resolution: 96 mean optimized for the screen -> conclusion less use of JPEG/PNG compression feature but lowest useful resolution. My proposal: - JPEG Quality Default: 80 - PNG Compression Default: 7 - Resolution Default: 300 DPI for single image compression (default is optimizes for printout) 150 DPI for impress
Please make the request more specific. What module and dialog do you have in mind?
Created attachment 157005 [details] Image Compression default's Study how different settings will look like. Solution for Compress Image will be: - jpeg quality default = 80 - png compression default = 6 - resolution default = 300 DPI the patch for the default change. https://gerrit.libreoffice.org/c/core/+/86431 an additional patch could be to deactivate Reduce image resolution by default.
Created attachment 157006 [details] Powerpoint Image optimization Dialog Powerpoint has the following Resolution settings: - High Fidelity = Default (Reduce image resolution not set) - HD 330 ppi - Print 220 ppi - Web 150 ppi - E-Mail 96 ppi
The patch for impress presentation optimizer https://gerrit.libreoffice.org/c/core/+/86436 I use similar settings than Powerpoint - E-Mail 96 DPI JPG 70 - Web 150 DPI JPG 75 - Print 300 DPI JPG 80 - High Fidelity (Reduce image resolution not set)
Sounds like a good plan
