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

I have uploaded three files to demonstrate the problem (the PNG shows the graph
as I want it to appear):


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

The PDF shows a white border on the bottom and right edges of the image and

Expected results:

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.
