Could you explain what's the difference between ''Magnification lens'' and ''Fish-eye lens''? --[[User:Pajarico|Pajarico]] 01:38, 10 July 2008 (UTC) | |||

Summary
I try to bring lens effects to vectorial objects in a way the user can experiment playing with settings like focal distance, diameter and position of the lens over the object (meaning the user can apply the effect over a part of the object, like a magnifying glass).
Synfig has a similar tool (example here).
Scribus also has this implemented in 1.3.5svn version --Prokoudine 11:31, 8 July 2008 (UTC)

Release Note
Rationale
Lens effects are really hard to achieve manually. The specs brings the possibility to create these effects easily with the non-destructive approach of LivePath effects.
Design
UI
The dialog has to do these things:
Usage
SVG representation
TODO
Discussion
I need ideas about which settings should appear so it has some correlation with a real lens system, like:
- f number.
- focal lenght (distance between lens and film).
Or maybe is better to make the UI in layman terms (like the Scribus example above). Other random ideas:
- Lens flares (Maybe several forms or an object from the clipboard, like this).
- Clip option: clips the object to the circumferenced helper.
