Blur Filter

Accurate Image Manipulation for Desktops

# Blur Filter, 8th Aug 1999

# Description

> Weighted Mean and Average blurring over 3x3 kernel.

> This is a very delicate filter, the maximum amount 100 equals to radius of only 0.6 in the Gaussian Blur of Photoshop. This filter allows to apply a final touch-up blurring far more accurately (100 steps) than the Gaussian Blur that only has 5 steps over the effective range of this blur filter.

# Selection Dropdown

> Weighted Mean, uses 1,2,4 type gaussian mean over the 3x3 kernel.
> Average, computes the average of the 3x3 kernel.

# Check Boxes

> 0/255 Inv

> > This is a preview function. When enabled it will give visual feedback for pixels that have channel value 0 or 255. This greatly helps in setting the black-point and white-point accurately. Slowly enable/disable the 0/255 Inv check-box to see the effect.
