jit.path & gl.path setscale

I’m using a jit.path for building and moving a 3d form generated with a jit.gl.path.
My problem is that i can’t use the setscale in the gl.path cause the jit.path is immediately overruling it!
so i thought jit.path is setting the scale of each point… but it actually doesn’t.
I took a look to the matrix that comes out from the jit.path and it’s double of cells! so if i have 30 points i have a matrix of 30×2.
So there is a second row of pixels but it is completely zeroed and it does nothing apparently.
Does somebody knows something about it?

hello. the second row in the path matrix contain the handle/tangent values for each point in the path.
however, if your @interpmode is still the default value of “linear”, these values will be 0 (linear interpolation does not use tangents).

post a patch showing your problem with the scale values, and i’ll be happy to take a look.

check out the “Discussion” section of the jit.path reference file, for more information on the matrix output.
