738524 - Override Firefox page zoom in/out so that pdf text gets re-scaled when needed.

Status: RESOLVED WORKSFORME

(Firefox :: PDF Viewer, defect)

Description

[Olli Pettay [:smaug][[e-mail]]]

Currently zooming in using ctrl++ or ctrl+mousewheel makes the
text to look ugly. pdf.js could override FF's normal zoom in/out and
apply the zoom level to pdf area only.

Also currently zooming in using ctrl++ or ctrl+mousewheel also magnify the GUI of the PDF Viewer which is weird

What's the expected usability for this? Should performing a zoom-action zoom the entire page if the user doesn't checked View->Zoom->"Zoom Text Only" or just the pages of the PDF Viewer (= change the zoom level on top).

Is there some zoom-event we can hook into? How would you overwrite the zoom in/out?

It should zoom the zoom level of the PDF FIle, since this is the content.

In the latest nightly (18.0a 2012-09-26)  this is solved for me.

Definitely the UI should not be zoomed. And also the result should not be blurry. Or no more blurry than without zoom.
