Chapter 4 Working with Effects and Filters
190
The PixelChooser performs the same basic operations in most filters. After examining each
pixel in the image, it decides how to process each pixel based on its location and/or the
channel values in that pixel or the corresponding pixel in the PixelChooser Track.
• If it decides that a pixel not does meet the selection criteria, the source pixel is copied to
the output and left unfiltered. Unfiltered pixels are black in the mask.
• If it decides that a pixel fully meets the selection criteria, the filtered pixel replaces the
source pixel in the output. Filtered pixels are white in the mask.
• If it decides that a pixel partially meets the selection criteria, a mix of the source pixel
and filtered pixel appears in the output. Partially filtered pixels are gray in the mask.
