Uses of PredictorAlgorithm in org.apache.pdfbox.pdmodel.graphics.predictor
Subclasses of PredictorAlgorithm in org.apache.pdfbox.pdmodel.graphics.predictor Modifier and Type Class Description class
Average
We can use raw on the right hand side of the decoding formula because it is already decoded.class
None
The none algorithm.class
Optimum
In an Uptimum encoded image, each line takes up width*bpp+1 bytes.class
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.class
Sub
