Comment 12 for bug 1891682

Thierry, thanks for the update. That is good news and so we know that the eSCL protocol is well investigated by you and Alex and so we can improve the support for it more and more. So I hope also that Alex will take you newest additions as base to complete the eSCL part of sane-airscan, to make it a universal backend making all AirScan scanners fully working. AFAIR sane-airscan does not have all of Brightness, Threshold, Sharpen, and Contrast yet.
For the devices which require PDF to work, do they work with current sane-escl and/or sane-airscan? For Scanner Applications we will be able to convert forth and back between PDF and raster formats as I have made library functions out of all CUPS filters.
