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.
