Bug#443782: evince renders transparent color in PDF incorrectly

Mon Sep 24 03:21:23 UTC 2007

Package: evince
Version: 0.4.0-5
Severity: normal

A very simple drawing was generated with OOO Draw
(2.0.4) and exported as PDF.  The drawing contains two
elements: 1) a background rectangle of solid color,
and 
2) a foreground ellipse set to 85% transparent.

The mixed color of the semitransparent foreground is
as expected in the original OOO, as well as in the
exported PDFs when viewed with xpdf (3.0.1) and 
acroread (8.1.1).  Evince, however, renders the
foreground color incorrectly.

Test files attached.
