view/edit current transform decomposed into rotation/scale/.

Originator: NO

Isn't the Matrix tab of Transform dialog what you are requesting?

Hi buliabyak.
The Matrix Tab lets you edit the same matrix values that you can edit
directly through the xml editor (or that are created if your input in the
xml editor includes rotation() or scale()):
you edit the transformation matrix elements, but this values are not
friendly... you cannot see what they mean without the mathematics involved
(or can you and i don't know how???):
For example. If you draw a rectangle or a circle, you get this matrix
values:
A: 1,0 B:0,0 C:0,0 D:1,0 E:0,0 F:0,0
If afterwards you rotate it 15 degrees, the matrix would show:
A: 0,966 B: -0.259 C: 0.259 D: 0.966 E: 0 F: 0
The idea would be to have a dialog where you can see the 15 degrees (after
rotating) and reset them to 0, while the scale remained 100% all the
time... do i explain myself?
Thanks for your answer!

Maybe a possibility would be to add a checkbox to each of the other tabs
of the transform tab similar to "edit current matrix" in the matrix tab...

I saw that inkscape doesn't write the changes in "scale" or "translation"
to the transformation matrix, but writes them as height/width or x/y values
(except for certain objects like stars, where it keeps also translation
values)...
So inkscape's trasform matrix use isn't standard for all objects...
...I also took a look in the svg specification and saw that it's not so
easy to decompose the matrix (if that is actually possible because
rotation, skewness and scale values are all product of multiplications...)
Have you thought about keeping a history of changes in
scale/rotation/skewness somewhere else? what I intended with this request
was to ask for a way to be able to change current rotation or scale
values...

It's controlled by the preference: store transforms embedded (default) or
separate
