Using filters to create animated effects
You can use Auto Filter to create dramatic animated effects with bitmap filters. Auto Filter applies
a filter incrementally to a series of cast members. You can use it either to change a range of
selected cast members or to generate a series of new filtered cast members based on a single image.
When you define a beginning and ending setting for the filter, Auto Filter applies an intermediate
filter value to each cast member.
You can tween a bitmap filter with Auto Filter.
Note: Although most filters do not support auto-filtering, the Auto Filter dialog box lists only those filters that
support it.
To use Auto Filter:
1
Select a bitmap cast member or a range of cast members, and select Xtras > Auto Filter.
If you want to change only a portion of a bitmap cast member, use the Marquee or the Lasso
tool in the Paint window to select the part you want to change.
2
In the Auto Filter dialog box, select a filter.
3
Click Set Starting Values, and use the filter controls to enter filter settings for the first cast
member in the sequence.
When you finish working with the filter controls, the Auto Filter dialog box reappears.
4
Click Set Ending Values, and use the filter controls to enter filter settings for the last cast
member in the sequence.
5
Enter the number of new cast members you want to create. The text box is not available if you
selected a range of cast members.
6
Click Filter to begin the filtering.
A message appears to show the progress. Some filters are complex and require extra time for
computing.
Auto Filter generates new cast members and places them in empty cast positions following the
selected cast member. If you selected a range of cast members, no new cast members appear,
but the cast members in the range you selected are changed incrementally.
