Is there a way to get scale to work correctly on rotated objects?

[chris cummings]

If I create a rect() or even a path() object in the shape of a
rectangle, rotate it 45 degrees and then try to scale it, it scales as
you would expect *before* the rotation.

So, running:

var s1 = paper.rect(50, 50, 70, 70);
s1.rotate(45, 0, 0).scale(1, .7).translate(100, 0);

doesn't produce an isometric-like view(diamond shape) but instead just
a rectangle at an angle.

Here is image to better illustrate my problem:

Nothing? Really?

Apparently there's some new transformation stuff coming in 2.0,
which is a nearly-complete rewrite. Dmitry, can you tell us what
your plans are?

[chris cummings]

Any idea when 2.0 is supposed to drop? I didn't find anything on the
site or twitter feed about a release date.

[Dmitry Baranovskiy]

2.0 beta release should be in March. Final release should be in April–
May.

Due to a massive rewrite (over 60%) there are lots of testing.

It’s worth waiting…

Any hints on what exciting new functions will come with the new version?

To Dmitry...
That's all good.

I saw a Twitter message yesterday where you said anyone wanted something in it (2.0)
Tell us now. Just wanted to mention Radial Gradients for paths. I understand you have a new setup for VML?
----------------------------------
Anyway with respect to the person who stareted this subject, sorry this was off topic. Hope yiou found a work around.
Using getBBox to analyse and adjust might be an idea after the initial attempted transform?

Charles,

No, no solution yet. =/

Can you elaborate on your suggestion using getBBox?

[sittichok chartpongsree]

I'm sorry for my language. I'm thai.

This problem need skew transformation more detail in this http://www.propplan.com/#!/projects/propplan/raphaeljs/rotate-and-scale .

I need this transformation too but raphaeljs don't have. If you need skew transformation , please tell Dmitry.

getBBox return size of the object but it return not correct value if path have curve.

Here is an interactive example for getBBox
http://www.irunmywebsite.com/raphael/additionalhelp.php?q=getBBox

It worked on all path tests I did (so far)
If your scaleing then the app / Raphael is doing it on the shape? Which is probably to SVG spec?

You might have to write a bespoke solution for skewing and I would use path for that as the primitive equivalent will not be of use?

I sorry for "getBBox return size of the object but it return not correct value if path have curve"

Method getBBox return correct value. I don't use this method so far. Sorry.

For SVG only there is a solution using the group plugin (http://
2hats.net/_box/raphael/grouping.html).
Maybe someone has time to do it for VML too :)
