TAgg2D.TransformImagePath(bitmap, dstX1, dstY1, dstX2, dstY2)

Description

Draws a TBitmap image as an interior of currently defined path at image size defined by target surface rectangle.

Parameters

bitmap: TBitmap

Reference to non empty pf32bit TBitmap (or descendant).

dstX1: double

X coordinate of target surface rectangle Top Left corner, relative to the Top Left bounding box of currently defined path to be filled with image [in subpixels].

dstY1: double

Y coordinate of target surface rectangle Top Left corner, relative to the Top Left bounding box of currently defined path to be filled with image [in subpixels].

dstX2: double

X coordinate of target surface rectangle Bottom Right corner, relative to the Top Left bounding box of currently defined path to be filled with image [in subpixels].

dstY2: double

Y coordinate of target surface rectangle Bottom Right corner, relative to the Top Left bounding box of currently defined path to be filled with image [in subpixels].

Example

// Cut and paste this into the tagg2d_example08.zip

if VG.Attach(Image1.Picture.Bitmap) then begin

  VG.ClearAll(255, 255, 255, 0);

  // Setting master parameters
  VG.MasterAlpha(TrackBar2.Position / 255);
  VG.AntiAliasGamma(TrackBar3.Position / 10);
  VG.BlendMode(BM);
  VG.FillEvenOdd(true);

  // Rotate path with Lena image around own axis
  VG.Translate(30, 30);
  VG.Scale(1.5, 1.5);

  VG.Translate(-(50 + Image2.Picture.Bitmap.Width / 2),
   -(150 + Image2.Picture.Bitmap.Height / 2));
  VG.Rotate(Deg2Rad(TrackBar1.Position));
  VG.Translate((50 + Image2.Picture.Bitmap.Width / 2),
   (150 + Image2.Picture.Bitmap.Height / 2));
