Class Summary
Average | We can use raw on the right hand side of the decoding formula because it is already decoded.
None | The none algorithm.
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.
PredictorAlgorithm | Implements different PNG predictor algorithms that is used in PDF files.
Sub | The sub algorithm.
Up | The up algorithm.
Uptimum | In an Uptimum encoded image, each line takes up width*bpp+1 bytes.
