Picture PrintPreview and Printing

VCL TMS VCL UI Pack

Hello,

i have a Picture inserted in an cell with AddPicture. The quality of the picture inside the grid is nice.
PrintPreview generated a bad graphic, but the print is OK.
Is the bad picture quality normal for the preview or how can i reached a better quality?

Best regards
Marco.

What exactly are you using for the print preview?
Is what you see a result of stretching? Most likely the image needs to be stretched for the preview on display.

If so, there is not really a built-in possibility to have a better stretching in the preview.

Hello Mr. Fierens,

procedure TForm1.Button2Click(Sender: TObject);
var
  aPicture: TPicture;
begin
  aPicture := TPicture.Create;
  aPicture.LoadFromFile('IMG_1958.JPG');
  Grid2.RowHeights[1] := 400;
  Grid2.AddPicture(0,1,aPicture ,False,Stretch,0,haCenter,vaCenter);
  AdvPreviewDialog1.Execute;
end;

Equal, what TStretchMode i use (also nostretch), the preview is bad.
