> Thomas on stackoverflow has very simple 16 bit PNG image into PDF code that
> displays fine on Adobe Reader in 2.0.8 but no longer since 2.0.12. It
> displays on all other viewers I've tried: PDFBox, GS, PDF.js and Chrome. It
> works again when disabling the predictor logic in LosslessFactory.java.
> Thomas and I narrowed the problem last evening and now he has a non
> confidential file for us and also a workaround on his side.
> cc [~rototor]
> the "bad" file has imageType custom, colorspace with getNumComponents = 1, 8
> bpc, data buffer TYPE_BYTE
