The predictor package contains code for different PNG predictor algorithms that
are present in PDF documents. These classes are used internally by PDFBox.
|
Java Source File Name | Type | Comment |
Average.java | Class | We can use raw on the right hand side of
the decoding formula because it is already decoded. |
None.java | Class | The none algorithm. |
Paeth.java | Class | 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.java | Class | Implements different PNG predictor algorithms that is used in PDF files. |
Sub.java | Class | The sub algorithm. |
Up.java | Class | The up algorithm. |
Uptimum.java | Class | In an Uptimum encoded image, each line takes up width*bpp+1 bytes. |
