Subject: Acquire with ShowUI=true

Hello Michel,

how can I get information about ImageFormat and XYResolution with ShowUI=true? I need it to select the best image filetype and compression.

If user acquires a bw image, my app shall save it automatically as tif fax g4, if he scans truecolor, my app shall save it as jpeg. Please have a look at the following source. Can I do so or what goes wrong?

procedure TXImageFrame.Acquire(const DibHandle: THandle; const XDpi,
YDpi: Word; const CallBackData: Integer);
var Graphic: TDibGraphic;
Graphic := TDibGraphic.Create;
Graphic.XDotsPerInch := XDpi;
Graphic.YDotsPerInch := YDpi;
case Graphic.ImageFormat of
ifBlackWhite: with TTiffGraphic(Graphic) do begin
Compression := tcGroup4;
ifTrueColor: TJpegGraphic(Graphic).SaveToFile('c:\temp\test.jpg');

Thank you very much and regards from germany
