46996 - [RFE] XUL Lense

Status: VERIFIED WONTFIX

(SeaMonkey :: UI Design, enhancement, P3)

Description

[rbs]

Certain viewers offer the ability to "zoom" in a particular area of the
current window. For example, with xdvi, when right-clicking in a particular
position of the window, a small popup appears containing an enlarged rendering
of the content surrounding the position of the cursor. The enlarged content of 
the popup is kept in sync as the cursor moves around while pressing the
right button.

Mozilla already zooms with "View -> Engarge Text Size" but unfortunately, 
this applies to the *whole* document.

This bug reports is a request for a lense widget in XUL, to allow the
zoom process to be confined in small section (like in the xdvi example
mentioned above).

A possible implementation could be to open the popup with an appropriate
zoom factor for the rendering context, and pass a suitable DOM fragment
(or something) to Gecko to display the portion of interest.

Interesting feature.
However; This could be considered an os function. Windows 2000 comes w/ a 
magnifier application, which works pretty well.

Don, feel free to assign to nobody.

good idea, we need to get to 1.0 before doing stuff like this.
Throwing out to the nobody hounds.

I really think this should be WONTFIX. This would be better done by the OS and
at least two operating systems that I have used come with such a feature as
standard, including Windows which has most of the market.

[Blake Ross]

Agreed.

Ok, VERIFIED. Use the Windows 2000 Magnifier or equivalent accessibility tool on
your platform.

[RFE] is deprecated in favor of severity: enhancement.  They have the same meaning.
