If a
matrixType
function fails if any of them are missing. This matrix scales, translates, rotates, and skews the
unit gradient, which is defined at (-1,-1) and (1,1).
•
,
matrixType
The properties indicate the following:
position relative to the registration point of the parent clip for the upper left corner of the
gradient, is the vertical position relative to the registration point of the parent clip for the
y
upper left corner of the gradient,
and is the rotation in radians of the gradient.
r
The following example uses a
an object with these properties.
this.createEmptyMovieClip("gradient_mc", 1);
with (gradient_mc) {
colors = [0xFF0000, 0x0000FF];
alphas = [100, 100];
ratios = [0, 0xFF];
matrix = {matrixType:"box", x:100, y:100, w:200, h:200, r:(45/
180)*Math.PI};
beginGradientFill("linear", colors, alphas, ratios, matrix);
moveTo(100, 100);
lineTo(100, 300);
lineTo(300, 300);
lineTo(300, 100);
lineTo(100, 100);
endFill();
}
