Status: RESOLVED WORKSFORME

(Firefox :: PDF Viewer, defect, P3)

Description

[Ward Vandewege]

Attachment: CDLS_2013_brochure.pdf

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0 Iceweasel/20.0 (Beta/Release)
Build ID: 20130402195902

Steps to reproduce:

Visit http://www.iofc.org/sites/all/files/CDLS_2013_brochure.pdf in firefox and compare with local rendering on evince, or another PDF reader.


Actual results:

The rendering of the PDF is very slow. The rendering of the PDF is incorrect: backgrounds are missing/shifted from where they should be.

Page 1: Kevin Rudd's picture is covered by part of a background square that is incorrectly offset. Luc Gnacadja's picture is covered by another dark gray square that shouldn't be there.

Page 2: image at the top left of the page is incorrectly rendered; it appears to be compressed horizontally. Background overlays on the rest of the page are incomplete. 

Page 3: gradient background at 'Experts workshops' is not rendered correctly.

Page 2: 


Expected results:

The PDF should have rendered much more quickly and without all these artefacts.

Smask issue was fixed by https://github.com/mozilla/pdf.js/pull/4161

I can confirm that the output from pdf.js looks identical to the output from evince. Performance is reasonable, taking a few seconds in pdf.js to render.
