Effect class (gdipluseffects.h)

The Effect class serves as a base class for eleven classes that you can use to apply effects and adjustments to bitmaps. The following classes descend from Effect.

• Blur
• Sharpen
• Tint
• RedEyeCorrection
• ColorMatrixEffect
• ColorLUT
• BrightnessContrast
• HueSaturationLightness
• ColorBalance
• Levels
• ColorCurve

To apply and effect to a bitmap, create an instance of one of the descendants of the Effect class, and pass the address of that descendant to the Graphics::DrawImage method or to the Bitmap::ApplyEffect method.

Methods

The Effect class has these methods.

Effect::Effect Creates an Effect object.
Effect::GetAuxData The Effect::GetAuxData gets a pointer to a set of lookup tables created by a previous call to the Bitmap::ApplyEffect method.
Effect::GetAuxDataSize The Effect::GetAuxDataSize method gets the size, in bytes, of the auxiliary data created by a previous call to the Bitmap::ApplyEffect method.
Effect::GetParameterSize The Effect::GetParameterSize method gets the total size, in bytes, of the parameters currently set for this Effect. The Effect::GetParameterSize method is usually called on an object that is an instance of a descendant of the Effect class.
Effect::UseAuxData The Effect::UseAuxData method sets or clears a flag that specifies whether the Bitmap::ApplyEffect method should return a pointer to the auxiliary data that it creates.
