850311 - PDF Viewer in Firefox 19 does not preserve PDF's transparent qualities

Status: RESOLVED DUPLICATE of bug 843321

(Firefox :: Untriaged, defect)

Description

[sarah]

Attachment: PDF Viewer Comparison.doc

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0
Build ID: 20130307023931

Steps to reproduce:

Our organization (a land trust) has numerous PDF files available to the general public (trail guides, driving directions, brochures, etc).  However, in the new PDF Viewer in Firefox 19, specific formatting within the PDF (such as image transparency).  This is a problem because many of our PDFs contain background images that are slightly transparent with text overlaid.  Without the transparency, the text is unreadable.  This is a problem, as many of our members probably do not realize that the issue is Firefox based, and thus will probably not try to view the PDF any other way.

Here is a link to one of our PDF files: http://www.lclt.org/images/stories/ButternutHillGuide.pdf

If you open the above file in a different browser or in Adobe, the transparency should work.  If you open it in the Firefox PDF Viewer, the transparency won't work.


Actual results:

PDF transparency is not preserved in Firefox PDF Viewer.


Expected results:

Transparency should be preserved (formatting of PDFs should not be altered).

Sorry, I apparently didn't finish my thought: "However, in the new PDF Viewer in Firefox 19, specific formatting within the PDF (such as image transparency)is not preserved, changing the quality of the file, and in our case, making the file unreadable."
