Extending Flash - Flash JavaScript Question

Question

This is probably not the place to post this, however I don't
know where to post it.
I'm attempting to use .jsfl to add a gradient to a shape. The
gradient fills fine with one problem, I can't rotate the gradient,
so instead of going from left to right to up and down:
var doc = fl.getDocumentDOM();
var fill = doc.getCustomFill();
fill.style = "linearGradient";
fill.colorArray = [ 0x000000, 0xffffff ];
fill.posArray = [0, 255];
var mat = fill.matrix;
mat.a = 0;
mat.b = 1;
mat.c = -1;
mat.d = 0;
fill.matrix = mat;
doc.setCustomFill(fill);
I would assume that the matrix object would affect this
however I cannot get it to work.
Thank you

Answer 1

After a lot of trial and error I managed to figure it out.
The key problem here is that once a gradient is applied to an shape
it is difficult to modify it. I found that if I first fill the
shape with a flat color, then apply the gradient it works.
I was able to rotate the gradient 90 degrees and 45 degrees,
the code below rotates the gradient 90 degrees. To rotate the
gradient 45 degrees change matrix.a and matrix.b to 1. matrix.tx
and matrix.ty appear to do nothing.
var doc = fl.getDocumentDOM();
var fill = doc.getCustomFill();
fill.style = "solid";
fill.color = 0xffffff;
doc.setCustomFill(fill);
fill.style = "linearGradient";
fill.linearRGB = false;
fill.colorArray = [ 0x000000, 0xffffff ];
fill.posArray = [0, 255];
var mat = fill.matrix;
mat.a = 0;
mat.b = 1;
mat.c = 0;
mat.d = 0;
fill.matrix = mat;
doc.setCustomFill(fill);
