evince interpolates image by mistake

[Dominik Holler]

Binary package hint: libpoppler0

feistys evince 0.8.1 (poppler 0.5.4 cairo) shows images interpolated, if the pdf does not say "/Interpolate true".
If the pdf not says "/Interpolate true", evince should show the image not interpolated.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.
 We have instructions on debugging some types of problems. http://wiki.ubuntu.com/DebuggingProcedures
At a minimum, we need:
1. the specific steps or actions you took that caused you to encounter the problem,
2. the behavior you expected, and
3. the behavior you actually encountered (in as much detail as possible).
Thanks!

Sorry, I wrote very detailed and assumed the reader is familar with the pdf file format.

1. download
  http://png2pdf.sourceforge.net/png2pdf.pdf
  and look at "Figure 7: Image without interpolation"
2. "Figure 7: Image without interpolation" should be shown different from "Figure 8: Interpolated image"
3. but evince shows the "Figure 7: Image without interpolation" interpolated, so Fig. 7 looks like "Figure 8: Interpolated image"

harydy's evince 2.22.1.1 [poppler 0.6.4 (cairo)] is also effected
