Hej

Jeg er ved, at afprøve en procedure PrintImage
og vil havde den til, at kunne print Image billedde ud.
DrawImage står der sidst i proceduren her opstår der en fejl.
Har du en ide ti denne linje?

procedure PrintImage(Image: TImage; ZoomPercent: Integer);
// if ZoomPercent=100, Image will be printed across the whole page
var
relHeight, relWidth: integer;
begin
Screen.Cursor := crHourglass;
Printer.BeginDoc;
with Image.Picture.Bitmap do
begin
if ((Width / Height) > (Printer.PageWidth / Printer.PageHeight)) then
begin
// Stretch Bitmap to width of PrinterPage
relWidth := Printer.PageWidth;
relHeight := MulDiv(Height, Printer.PageWidth, Width);
end
else
begin
// Stretch Bitmap to height of PrinterPage
relWidth := MulDiv(Width, Printer.PageHeight, Height);
relHeight := Printer.PageHeight;
end;
relWidth := Round(relWidth * ZoomPercent / 100);
relHeight := Round(relHeight * ZoomPercent / 100);


Her ønsker / mener jeg der skal Image1 osv

DrawImage(Printer.Canvas, Rect(0, 0, relWidth, relHeight),
Image.Picture.Bitmap);


end;
Printer.EndDoc;
Screen.cursor := crDefault;
end;

// Example Call:

procedure TForm1.Button1Click(Sender: TObject);
begin
// Print image at 40% zoom:
PrintImage(Image1, 40);
end;



Mvh
