Blur edges by feathering
Feathering blurs the edges of a pixel selection and helps to blend the selected area with the surrounding pixels.
Feathering is useful when you copy a selection and paste it onto another background.
1
Import the image that you want to feather on the canvas using File > Import.
2
Select the part of the image that you want to feather using any of the selection tools.
3
Select Select > Inverse.
4
Select Select > Feather. Alternatively, you can select the option from the Edge menu in the Properties panel.
5
In the Feather Selection dialog box, type a feather radius value. The default value of 10 is good for most practical
purposes. Alternatively select a value for the feather radius in the Edge menu.
6
Press Delete.
Adjust bitmap color and tone
For more information, see “
Control how a document redraws on the screen
” on page
29.
Use color- and tone-adjustment filters to improve and enhance the colors in your bitmap images.
To apply filters that are removable, editable, and that do not permanently alter pixels, use Live Filters. Adobe
recommends using filters as Live Filters whenever possible.
Note:
Although Live Filters are more flexible, large numbers of Live Filters in a document can slow down Fireworks'
performance.
To apply filters in an irreversible, permanent way, select them from the Filters menu.
You can't apply Live Filters from the Filters menu to pixel selections. You can define an area of a bitmap and create
a separate bitmap from it, and then apply a Live Filter to it.
If you apply a filter to a selected vector object using the Filters menu, Fireworks converts the selection to a bitmap.
Apply a Live Filter to an area defined by a bitmap selection marquee
1
Select a bitmap selection tool and draw a selection marquee.
2
Select Edit
> Cut.
3
Select Edit
> Paste.
Fireworks pastes the selection exactly where the pixels were originally located, but the selection is now a separate
bitmap object.
