Ralf	Posted - Apr 27 2017 : 06:32:26 Hallo, 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? Thanks Ralf

xequte	Posted - Apr 30 2017 : 00:33:51 Hi Ralf Setting paper size in WIA is not supported. You would need to use the X and Y Resolution properties. Also, setting Twain params has no effect on WIA acquisition Nigel Xequte Software www.xequte.com nigel@xequte.com
