1012700 - Blurred bar code image in PDF Boarding Pass

Status: RESOLVED DUPLICATE of bug 1722191

(Firefox :: PDF Viewer, defect, P3)

Description

[PALANI]

Attachment: FireFox issue for Barcode.docx

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

We are creating checkin application,

1. Complete check-in
2. Generate Boarding pass in Firefox browser
3. Boarding pass created in new firefox window but with blurred bar code image.
4. This is applicable for any online check-in application


Actual results:

Boarding pass created in new firefox window but with blurred bar code image.
But if we save the boarding pass as PDF and re-open it then it looks fine. So there is some issue in the default (Firefox) rendering functionality. 


Expected results:

The boarding pass should be generated with clear bar code image as other browsers (Chrome and IE). It is working fine even if we change the render from default one to Adobe PDF.

Could you attach a PDF with the bar code, please. We need a sample to test.
In addition, could you upload Firefox to the last version (29.0.1) and test again.

Example file as requested. A scan of the print showing the quality issue follows in a minute. This boarding pass is old (2013) to limit potential abuse, it looks virtually identical to the one I had a problem with today: The normal scanner at the entrance would not read it, an employee with a handheld scanner then let me in.

Removing the need-info request, I believe there are two different e-mail addresses for the same user.

Reproduced on latest Nightly 20140618030215 under Win 7 64-bit. Set as New.
