Hi,
I am revisiting what the ISO says about predictors and found... that
predictors are not considered by the PDF as a filter, they are an
internal part of the LZWDecode and FlateDecode filters as stated in the
7.4.4.3 section.
I think that it is still usefull for correct decoupling that the
predictors are implemented as a separate filter. Then, it is the
pdf_stm_filter_install() function who must test for [LZW,Flate]Decode
filters wheter they should be "predicted" first and create the predictor
filter in that case.
What do you think?
JP
