Abstract Classes:

PredictorAlgorithm   Implements different PNG predictor algorithms that is used in PDF files.  code | html

Classes:

Average   We can use raw on the right hand side of the decoding formula because it is already decoded.  code | html
None   The none algorithm.  code | html
Optimum   In an Uptimum encoded image, each line takes up width*bpp+1 bytes.  code | html
Paeth   From http://www.w3.org/TR/PNG-Filters.html: The Paeth filter computes a simple linear function of the three neighboring pixels (left, above, upper left), then chooses as predictor the neighboring pixel closest to the computed value.  code | html
Sub   The sub algorithm.  code | html
Up   The up algorithm.  code | html
