Description

TFilterDirectionalBlur is a wrapper for TDirectionalBlurEffect.

FMX.Filter.Effects.TFilterDirectionalBlur inherits from FMX.Filter.Effects.TDirectionalBlurEffect. All content below this line refers to FMX.Filter.Effects.TDirectionalBlurEffect.

TDirectionalBlurEffect is a class for creating an effect that blurs, using a directional blur algorithm, the texture of visible objects.

For further information, go to TImageFXEffect and FireMonkey Image Effects.

The direction of the blur can be changed using the Angle property, and the blur amount of the effect can be changed using the BlurAmount property.

The following table shows the results of and differences between blur effects on a .png picture (with transparent background) placed on a form (using a TImage object). For TDirectionalBlurEffect, in the following example, the Angle is set to 45 degrees.

No effect (original picture)	TBlurEffect | Softness=0.3	TRadialBlurEffect | BlurAmount=3
	TGaussianBlurEffect | BlurAmount=0.3	TBoxBlurEffect | BlurAmount=3
	TDirectionalBlurEffect | BlurAmount=3 Angle=45	TBlurTransitionEffect | Progress=30
