Summary: low resolution graphic appears smoothed
Product: poppler
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: major
Priority: medium
Component: cairo backend
AssignedTo: poppler-bugs at lists.freedesktop.org
ReportedBy: carlosgc at gnome.org

I have a graphic showing a low resolution image with graph axes superimposed,
saved as both EPS and PDF. When I view either file with Evince, the graphic
appears smoothed. When I view the PDF with Acroread, I can see the individual
pixels.
I have uploaded three files to demonstrate the problem (the PNG shows the graph
as I want it to appear):
http://www.magres.nottingham.ac.uk/~magill/pixels/pixels.png
http://www.magres.nottingham.ac.uk/~magill/pixels/pixels.pdf
http://www.magres.nottingham.ac.uk/~magill/pixels/pixels.eps
I am using Gentoo Linux, fluxbox, evince 0.5.0, poppler-0.5.0-r5 (cairo)
Steps to reproduce:
1. open pixels.eps
2. open pixels.pdf
3. compare to pixels.png
Actual results:
The image appears as a smooth gradient.
The PDF shows a white border on the bottom and right edges of the image and
colourbar.
Expected results:
see pixels.png - I expect to see individual pixels in the image, and no white
border on the PDF. The PDF file displays as expected in Acroread. The EPS file
appears correct if displayed with xv.
I can confirm this is only reproducible with cairo backend.
