Hi, i want to offer our customer a array of possible DPI-Sizes for Scanning. To see witch size is possible i use TWainParams.XResolution.RangeMax. This work good with our Fujitsu. With the Brother the value=0.
Here you can see the Twain and Driver version:
Here you can see the Configuration:
as you see the ICAP_XNATIVERESOLUTION is 600.
For getting this information i used a software from twain.org. Called twainapp.win64.installer.msi
The Question is why the XResolution.RangeMax is 0 and not 600.
I now do a couple of different tests to get information withch DPI-Sizes are Supported. 1. TwainParams.XResolution.count>0 2. TWainParams.XResolution.RangeMax>0 3. if 1 and 2 have no success i use the actual XResolution Thats not very nice. Best Regards
