Filling selections with color
The Fill command lets you quickly and uniformly fill a selection with the foreground or background
color, black, white, or gray. In addition, select an opacity level and transfer mode for application of
the color.
To fill a selection with a color:
1. With an area of an image selected, choose Image | Filter | Other | Fill or use the Filter menu
in the Properties bar.
2. In the Fill dialog box, choose a fill option from the Use pop-up menu. To make the color
appear transparent, set the Opacity level to less than 100%. To use a mode effect, choose an
option in the Mode pop-up menu.
3. Click OK to fill the selection.
Creating custom image filters
You can create your own special-effect and image-correcting filters using the Custom command. You
can also save custom filters and use them in future Canvas documents.
Filters work with an image one pixel at a time. Using a mathematical formula and the color values of
pixels within a specified radius, filters assign each pixel a new color value. In a custom filter, you
supply the numbers the filter uses to calculate the new color values.
The same filter can produce different effects in other images. To get the most out of custom filters,
spend time experimenting.
