TImageEnProc.BumpMapping

Declaration

procedure BumpMapping(LightX, LightY, LampX, LampY, pcf: Integer; Color: TRGB);

Description

Apply a bump mapping effect to the current image.
Bump mapping is a technique to apply bumps and wrinkles to the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface.

Note:
◼ A UI for this is available to your users in the Image Processing dialog
◼ If the image PixelFormat is not ie24RGB, it will be converted

Parameter	Description
LightX/LightY	Source light position
LampX/LampY	Width and height of the source light
pcf	Percentage of the effect to apply to the original image (0 to 100)
Color	Source light color

Examples

ImageEnView1.Proc.BumpMapping( 100, 100, 50, 50, 10, CreateRGB(255, 255, 255) );

// Load test image
ImageEnView1.IO.LoadFromFile( 'D:\TestImage.jpg' );

// Apply a bump mapping effect to the image
ImageEnView1.Proc.BumpMapping( ImageEnView1.IEBitmap.Width div 2,
                               ImageEnView1.IEBitmap.Height div 2,
                               50, 50,
                               10, CreateRGB(255, 255, 255) );
