Emboss

procedure Emboss(img: TImage32; radius: Integer = 1; depth: Integer = 10; luminance: Integer = 75; preserveColor: Boolean = false);

Smaller radius is sharper, greater depth increases edge contrast and luminance changes grayscale balance (unless preserveColor = true)

Example 1

uses Img32, Img32.Extra, Img32.Fmt.PNG;
...
img := TImage32.Create;
img.LoadFromFile('fruit.png');
Emboss(img, 1,10);
img.SaveToFile('fruit_emboss.png');
img.Free;
