Class TGenericUniversalBitmap

Creates an image of dimensions AWidth and AHeight and fills it with Color

Creates a brush texture with a specified style, pattern color, background color, dimensions, and pen width.

Example using a diagonal cross texture to fill shapes on a form:

procedure TForm1.FormPaint(Sender: TObject);
var
  image,tex: TBGRABitmap;
  c: TBGRAPixel;
  x,y,rx,ry: single;

begin
    image := TBGRABitmap.Create(ClientWidth,ClientHeight,ColorToBGRA(ColorToRGB(clBtnFace)));
    c := ColorToBGRA(ColorToRGB(clWindowText));

    //ellipse coordinates
    x := 150;
    y := 100;
    rx := 100;
    ry := 50;

    //loads a "diagcross" brush with white pattern and orange background
    tex := image.CreateBrushTexture(bsDiagCross,BGRAWhite,BGRA(255,192,0)) as TBGRABitmap;

    image.FillEllipseAntialias(x,y,rx-0.5,ry-0.5,tex);
    image.EllipseAntialias(x,y,rx,ry,c,1); //draw outline

    image.RoundRectAntialias(x-rx-10,y-ry-10,x+rx+10,y+ry+10,20,20,c,11);
    image.RoundRectAntialias(x-rx-10,y-ry-10,x+rx+10,y+ry+10,20,20,tex,9);

    tex.Free;

    image.Draw(Canvas,0,0,True);
    image.free;
end;

These functions use the current pen style/cap/join. The parameter APenWidth specifies the width of the line and the base unit for dashes. See coordinate system.

• The coordinates are pixel-centered by default, so that when filling a rectangle, if the supplied values are integers, the border will be half transparent. If you want the border to be completely filled, you can subtract/add 0.5 to the coordinates to include the remaining thin border. See coordinate system.
