> Key: PDFBOX-2050
> URL: https://issues.apache.org/jira/browse/PDFBOX-2050
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.8.4, 1.8.5, 2.0.0
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Minor
> Labels: LZW
> Fix For: 1.8.6, 2.0.0
>
>
> According to the PDF spec "LZW and Flate Predictor Functions", both can have
> post processing with predictors. It is implemented for Flate but not for LZW.
> I am adding this by using the existing code from the Flate filter, which I
> will be moving into a helper class.
> While looking at the Flate filter, I noticed that its footprint is higher
> than needed, i.e. there is too much buffering. I will test this separately
> and commit only if I can measure an improvement.
