1136674 - Text selection broken in a PDF document

Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect, P3)

Description

[Martin Mitáš]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150222232811

Steps to reproduce:

Using FF36 on Mac OS X 10.8.5.

1. Go to http://www.ifoapplestore.com/stores/apple_stores.pdf
2. Select part of a text in a middle of the table (not first column). E.g. "Zhengzhou" (2nd table line on page 8).
3. Copy the selected (Apple+C or "Copy" in pop-up menu)
4. Paste it anywhere in FF (e.g. search box) or into other application (e.g. text editor).




Actual results:

Different text from the PDF document was pasted. In case of the "Zhengzhou", it pasted "anuary 10, 2015", i.e. part of text from different column in the table.

Different problem, possible different symptom of the same bug, is a problem to select a single word by double clicking. Often, the selected rectangle does not match boundaries of the word under the mouse.


Expected results:

I expect that exactly the selected text gets copied.

Looks like something is wrong with our heuristic here. If the pdf debugging tools are enabled you can see this with #textLayer=shadow.
