Namespace: FMX.RS.SVG

Parameters
aMatrix
Type: System.Void
cumulative transformations from the Parent element (and its Parents) to apply when drawing the element.
Canvas
Type: System.Void
Canvas to draw on
aRect
Type: System.Void
Rectangle to draw within
Overrides
TSVGGraphicElement.Draw(TSVGMatrix,TSVGCanvas,TSVGRect)
The TSVGDocument can be drawn to any TCanvas (though with a printer in VCL, you need to draw to an offscreen bitmap/png and then draw that to the printer.canvas). The following code paints to a TPaintBox.Canvas (FMX): Delphi |
procedure TForm20.PaintBox1Paint(Sender: TObject; Canvas: TCanvas); |
The VCL code is only slightly more complicated:
Delphi
uses
RSSVGTypes, RSGraphics;
procedure TForm1.PaintBox1Paint(Sender: TObject);
var
aCanvas: TSVGCanvas;
begin
aCanvas := TSVGCanvas.Create(PaintBox1.Canvas);
try
Doc.Draw(aCanvas, RectToRSRect(PaintBox1.ClientRect));
finally
aCanvas.Free;
end;
end;
