ImageEffects lets you apply visual effects to images. It is designed specifically for web server use which means it is both multithreaded and exceptionally fast.
ImageEffects has been engineered to mesh perfectly with ImageGlue. However you don t have to be using ImageGlue to take advantage of ImageEffects. As long as your ASP imaging component allows access to an HDC or HBITMAP you can use ImageEffects. 
ImageEffects supports the following effects. 
Median 
Sharpen 
Convolution 
Gaussian Blur 
Laplacian 
Unsharp Mask 
Despeckle 
Brightness 
Equalize 
Contrast 
Levels
