How i can determine the x,y start and the x,y end of scanning using the Delphi twain library ?
Also How i can set dpi for scan a document.
Thanks.
AFAIK, for setting a region to be scanned, you can use TTwainSource.SetImageLayoutFramework
method. TDelphiTwain.Source
returns available Twain sources.
For DPI, I guess you should first set CapUnits to tuInches using TTwainSource.SetICapUnits
method. Then you can set DPI by calling TTwainSource.SetIXResolution
and TTwainSource.SetIYResolution
methods.
