Constructor summary
Method summary
Signature Description
Matrix([a:Number],
[b:Number],
[c:Number],
[d:Number],
[tx:Number],
[ty:Number])
Creates a new Matrix object with the specified parameters.
Modifiers Signature Description
clone() : Matrix Returns a new Matrix object that is a clone of this
matrix, with an exact copy of the contained object.
concat(m:Matrix) :
Void
Concatenates a matrix with the current matrix,
effectively combining the geometric effects of the two.
createBox(scaleX:Num
ber, scaleY:Number,
[rotation:Number],
[tx:Number],
[ty:Number]) : Void
Includes parameters for scaling, rotation, and
translation.
createGradientBox(wi
dth:Number,
height:Number,
[rotation:Number],
[tx:Number],
[ty:Number]) : Void
Creates the specific style of matrix expected by the
MovieClip.beginGradientFill() method.
deltaTransformPoint(
pt:Point) : Point
Given a point in the pretransform coordinate space,
returns the coordinates of that point after the
transformation occurs.
identity() : Void Sets each matrix property to a value that cause a
transformed movie clip or geometric construct to be
identical to the original.
invert() : Void Performs the opposite transformation of the original
matrix.
rotate(angle:Number)
: Void
Sets the values in the current matrix so that the matrix
can be used to apply a rotation transformation.
scale(sx:Number,
sy:Number) : Void
Modifies a matrix so that its effect, when applied, is to
resize an image.
