This class represents the flate parameters. This is definitively detailed in:.

The Flate decode parameters dictionary configures the FlateDecode filter, which uses the zlib/deflate compression algorithm. FlateDecode is the standard general-purpose compression filter in PDF 1.2 and later.

The Predictor entry enables a pre-compression transformation that can significantly improve the compression ratio for certain data types, particularly image data with horizontal correlation between adjacent samples.

Predictor value 1 means no prediction. Values 2 through 15 select TIFF predictors; value 2 is the only TIFF predictor commonly used. Values 10 through 15 select PNG predictors, with 12 (PNG Up) and 15 (PNG Optimum) being the most effective for general data.

When a predictor is used, the Colors, BitsPerComponent, and Columns entries describe the sample structure of the data so the predictor can operate correctly row by row.
