Matrix object

var mat = fl.getDocumentDOM().selection[0].matrix;

mat.a = 0.5;

mat.b = 0.8;

mat.c = 0.8*(-1);

mat.d = 0.5;

fl.getDocumentDOM().selection[0].matrix = mat;

You can set a = d = 1 and c = b = 0 to reset the object back to its original shape.

matrix.b

Availability

Flash MX 2004.

Usage

matrix.b

Description

Property; a floating-point value that specifies the (0,1) element in the matrix. This value represents the vertical skew

of a shape; it causes Flash to move the shape’s right edge along the vertical axis.

The matrix.b and matrix.c properties in a matrix represent skewing (see matrix.c).

Example

In the following example, you can set b and c to -1 and 0, respectively; these settings skew the object at a 45º vertical

angle:

var mat = fl.getDocumentDOM().selection[0].matrix;

mat.b = -1;

mat.c = 0;

fl.getDocumentDOM().selection[0].matrix = mat;

To skew the object back to its original shape, you can set b and c to 0.
