I'm still have Problems with Setting the Papersize for the scanning. In Twain there is the possibility to set Papersize with TwainParams.StandardSize.CurrentValue:=ieTW_Size. For WIA I didn't find such way.
I thougt i can Set the Acquisition Frame in case of Wia or by Twain if setting TwainParams.StandardSize.CurrentValue doesn't work.
For Testing I used AllAquire Demo. I have different Scanner to test. For WIA-Scanner the AllAcquire Demo doesn't support the Setting of the Acquisition Frame. This is only supportet for Twain-Scanner.
Code i found in the AllAcquire Demo: if AcquireParams.SelectedSource.API = ieaWIA then chkFrameEnabled.Enabled := False;
Does that mean, that a setting of Frame in case of WIA isn't supported?
