Chapter 5: Painting And Image Editing
To use Blur and Blur More:
Blur slightly modifies an image. Blur More is about four times stronger than Blur. Both commands
work with all image modes except Black & White and Indexed.
1. Select one or more paint objects to blur. You can select an area in one image to blur the
selected area only.
2. Choose Image | Filter | Blur | Blur or Blur More.
Gaussian and Average blur
Create a softening effect by using the Gaussian Blur or Average blur filters. Their effects are similar,
but the Gaussian Blur filter creates a more diffused effect than the Average blur filter.
The Gaussian Blur filter changes the color value of each pixel by applying a weighted average based
on the color values of pixels within a specified distance. Color values at the edge of the specified
distance influence the final color value less than closer pixels.
The Average filter determines the new color value for each pixel by equally averaging all color values
within the specified radius.
To apply Gaussian Blur or Average blur:
1. Select one or more paint objects to blur. You can select an area in one image to blur the
selected area only.
2. Choose Image | Filter | Blur | Gaussian Blur or Average.
3. Specify a radius value from 0.1 to 250.0 in the Gaussian Blur dialog box, or 1 to 16 in the
Average dialog box. Smaller radius values produce more subtle effects than larger ones.
4. Click OK.
Depending on the size of the radius, applying a Gaussian or Average blur can take longer than other
Blur filters.
