processing for images and scenes. Several kinds
ofimagefiltersareprovided,seelistbelow.For
example, the Negative filter inverts the colors of
an image and the Fade filter fades an image in or
out over time.
An Image Filter event is usually a parent event with
a single child (which can itself be a parent with
children), for example, a Scene event, an Image
Input event, a Layer event that contains Scene or
Image Input events, or a Filter event that contains
Scene or Image Input events. You can also add
an Image Filter without a chi ld event, in w hich
case the Image Filter processes the result of the
previous events in the queue.
