TGaussianBlurEffect is a class for creating an effect that blurs the texture of visible objects using a Gaussian blur algorithm.

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

You can change the blur amount of the effect using the BlurAmount property.

The following table shows the result and differences between blur effects on a .png picture (with transparent background) placed on a form (using a TImage object).
