Bug Description

This is a feature request.

Currently the selection tool cycles between scaling and rotating the selected object, rather like Corel Draw.

The requested feature is this: add one more mode to the cycle, which allows all 4 corners to be freely placed.

Or, simply allow unconstrained movement of all 4 corners in the first mode, if both ctrl and shift are pressed together.

This would give us the often-requested "perspective" tool, in an intuitive and hopefully real-time-interactive way, and it should be relatively trivial to implement since the scaling tool already does 90% or more of what this would have to do.

The Effects->Modify Path->Perspective tool does the same thing, but in a terribly unintuitive way. The one thing going for it is reproducibility, which is often difficult with analog interfaces as I'm suggesting.

To help make the results reproducible, I suggest that the context tools offer height:height and width:width ratios so that they can be manually entered.

I'd also love to see the clone facility work with stepped ratios (as above), and possibly a jitter factor for each ratio. That would be quite the texture tool.

This is extremely important! I'm surprised that it's not at least in the beta builds already. It would be nice if all of the wishlist entries/blueprints got merged with this entry.

I don't mean to be grumpy but there's no point to go into details. If you're not familiar with possible applications of perspective tools you should read about it in Adobe Illustrator documentation or tutorials. Currently working with perspective in Inkscape is like creating svg's in XML editor with a preview window...

Just recall the entire [u]Inkscape perspective procedure[/u] (that alone, that it's a [u]procedure[/u], makes it a miss) and look at the simple figure I've done http://www.inkscapeforum.com/download/file.php?id=592. I won't even go into details how the workflow looked like because it would surely sound like a rant. Long story short lack of proper perspective tool that can be used on objects (not converted to paths) and object groups made me spend [b]4 times the amount of time I'd spend working with a proper perspective / free transform tool.[/b]

In Illustrator it's done in a [i]no questions asked[/i] manner i.e. you just do it.

A question:
Is there a build with the initial implementation of the tool available somewhere?
The "LPE perspective tool in SVN" or, preferably, some more recent work.

I would like to add my vote to this issue. I would particularly like it when I import a photo.

 I frequently need to correct photos for perspective before including them in an Inkscape drawing. Currently the easiest way to do this is in Gimp: I can drag the corners around until the image is corrected. then I import into Inkscape.

 It would be so great to do this in Inkscape. Imagine being able to select an image - or any other object or group for that matter - and then just dragging each corner independently until the desired effect was achieved.
