Description Alan Braslau 2008-03-23 12:33:11 UTC 
Version:           0.6.2 (using KDE 4.0.2)
Installed from:    Debian testing/unstable Packages

16-bit/color RGB images included in a PDF file are not rendered correctly in okular, (as for kpdf and xpdf), yet display correctly using acroread.

Note that the original 16-bit/color (png or tiff) image files ARE correctly displayed by okular (and kpdf).

Note also that the PDF file must indeed contain 16-bit images, as many programs (such as pdflatex, imagemagick, ...) simply silently convert to 8-bit depth, whereas others (ConTeXt) do respect the full color depth.

Hello,

unline KPDF, Okular does no rendering on its own. All the loading and rendering for PDFs is done using the Poppler library.
Please report the issue to the Poppler bug tracker (see http://poppler.freedesktop.org).

Thanks for your understanding.
