> TIFF-Predictor with 16 bits per component not supported
> -------------------------------------------------------
>
>                 Key: PDFBOX-2549
>                 URL: https://issues.apache.org/jira/browse/PDFBOX-2549
>             Project: PDFBox
>          Issue Type: Bug
>          Components: Rendering
>    Affects Versions: 1.8.7, 1.8.8, 2.0.0
>            Reporter: Tilman Hausherr
>            Assignee: Tilman Hausherr

> The attached image GWG181_16Bit_CMYK_X4.pdf from the Ghent Workgroup test 
> suite is not displayed, PDFBox throws the mentioned exception. One open 
> source and one closed source product display an "X", but gswin renders the 
> image properly. 
> The upcoming patch handles the 16bit case. I won't implement 1, 2 or 4 bpc 
> because I don't have test images.
> I'll add my patch 1.8 after the cut.
