Using the PixelChooser
The PixelChooser offers different way to selectively filter images. Filters can be applied to a
section of an image by specifying a geometric region or by using the image’s luma or color
information, without necessarily applying the effect to the entire image.
You can also use the PixelChooser feature across tracks. Note that all PixelChooser
parameters are animatable.
Here are some examples with illustration showing various PixelChooser options:
• In this example, the PixelChooser selects pixels based on the image’s Red channel,
causing the Spray Paint Noise filter to be applied only to pixels whose Red value is
highest.
• In this example, the PixelChooser’s region controls are used to specify a rectangular
area in which to apply the filter.
• In this example, both the channel controls and region controls are used to select pixels.
When the PixelChooser is selecting pixels based on both their channel values and their
location on the screen, pixels are chosen only if they are fully meet both of the selection
criteria.
