Subject: tif file not comressing and when faxed have gray background

Hi

I have downloaded the demo 1.1 for Delphi 5. I can scan into the ImageScrollBox ok and save the tif but it is not compressed. Also if I then fax the image using any windows fax software it has a gray background and takes about 10 minutes to fax. Winfax, MS Fax, APro Fax.

This is how I do it. (Code Below)
Most is copied from the help file.

Thanks

Andy Dyble

procedure TfmSitePlan.Acquire( const DibHandle : THandle;
const XDpi : Word;
const YDpi : Word;
const CallBackData : LongInt );
var

Graphic : TTiffGraphic;
ImageFormat : TImageFormat;
TiffCompression : TTiffCompression;

begin

Graphic := TTiffGraphic.Create;
try
ImageFormat := ifGray16 ;
TiffCompression := tcGroup3_1d ;
Graphic.AssignFromDibHandle(DibHandle);
Graphic.XDotsPerInch := XDpi;
Graphic.YDotsPerInch := YDpi;



Graphic.SaveToFile('\\toshiba\c\winapps\winida\scans\scan.tif');
ImageScrollBox1.LoadFromFile('\\toshiba\c\winapps\winida\scans\scan.tif',0);

finally
Graphic.Free;

end;
