Mode Default for Insert Media Into Writer

I submitted a bug report 104000 before I discovered what was going wrong.

Using insert-> image-> scan-> select source-> scan mode-> mode the default is lineart. How do I change the default to gray or color? Selecting color or gray works for one cycle only. There is no "Save" button.

Today when I again tried to scan, the choices of gray and color had disappeared and lineart is the only available choice in the mode dropdown. Recycling the selection process a second time revealed the gray and color choice.

Also, to get to the mode window takes several seconds for the scan mode window to appear so the internal coding must be very convoluted.

I am using LibreOffice 5.2.3.3 on Ubuntu 16.10 64 bit.

I'm using LibreOffice 5.1.3 (a bit old now) on Windows Vista. After selecting a source, nothing happens for me; probably something broken in my setup. However, the "Select Source" dialog looks identical to one used in GIMP, which does work and opens an external application to operate the scanner (either "Windows Image Acquisition" wizard or an application from the scanner manufacturer, depending which "source" I select).

Assuming it's similar on Linux, I'd guess that the actual dialog where you select the scan mode is some other application not directly under LibreOffice's control which defaults to a particular set of options. You may need to figure out what that application is (maybe XSane?), and see if it has any options for saving presets etc. If it's opening a separate application, that may also account for the delay opening the scanner options, which you previously mentioned.

Sorry I can't be much more help; perhaps someone else using Linux might be able to confirm some of the details.

Thanks for the suggestion. I will delve into it, and publish any finding.
Merry Christmas.
Blessings, Joe
