Chris Rolliston has a post up on the Embarcadero forum with a sample function for saving a Delphi XE5 Firemonkey TEffect to file. The trick looks like the ProcessEffect function of a TEffect which actually applies the effect to a bitmap which you can then save. The function relies on an effect being a child of the component you want to save the effect for but you can easily customize it to suite your own needs.

procedure SaveBitmapWithEffect(const Image: TImage; const FileName: string); var Child: TFmxObject; Effect: TEffect; R: TRectF; Temp: TBitmap; begin Effect := nil; for Child in Image.Children do if (Child is TEffect) and TEffect(Child).Enabled then begin Effect := TEffect(Child); Break; end; R := RectF(0, 0, Image.Bitmap.Width, Image.Bitmap.Height); Temp := TBitmap.Create(Image.Bitmap.Width, Image.Bitmap.Height); try Temp.Canvas.DrawBitmap(Image.Bitmap, R, R, 1); if Effect <> nil then Effect.ProcessEffect(Temp.Canvas, Temp, 1); Temp.SaveToFile(FileName); finally Temp.Free; end; end; |
