| CPUCoreCount (Inherited) | Returns number of detected CPU cores on the running machine. |
| ErrorCode (Inherited) | Returns error code after applying the effect. This value is a Constant defined in the PictureEffectsError module. |
| MultiprocessingHint (Inherited) | Use this property to fine tune CPU usage for this algorithm. By default this property is set to zero (Automatic). This property accepts all constants that are defined in PictureEffectsCPUUsage. |
| ProgressHandler (Inherited) | Use this property to use a progress class to get progress feedback from this function. This class must be a class that Implements the IProgressHandler Interface which is defined in this plugin. |
Methods
 Apply | Applies the effect on a given 32 bit source image with a given 32 bit mask and returns the result to a new image. |
| Apply | Applies the effect on a given 32 bit source image with parameters that have been set on the class instance. |
| Apply (Inherited) | Applies the effect on a given source image with a given mask. |
| ApplyInPlace | Applies the effect in place on a given 32 bit source image with a given 32 bit mask. |
| ApplyInPlace | Applies the effect in place on a given 32 bit source image with parameters that have been set on the class instance. |
| ApplyInPlace (Inherited) | Applies the effect on a given source image with a given mask without creating a new image, the result is written into the source image. Very Important read the remarks. |
