document.viewMatrix

Availability
Flash MX 2004.

Usage

document.viewMatrix

Description
Read-only property; a Matrix object. The

viewMatrix

is used to transform from object space to document space when

the document is in edit mode. The mouse location, as a tool receives it, is relative to the object that is currently being
edited. See

Matrix object

.

For example, if you create a symbol, double-click to edit it, and draw with the PolyStar tool, the point (0,0) will be at
the registration point of the symbol. However, the drawingLayer object expects values in document space, so if you
draw a line from (0,0) using the drawingLayer, it will start at the upper left corner of the Stage. The

viewMatrix

property provides a way to transform from the space of the object being edited to document space.

Example
The following example gets the value of the

viewMatrix

property:

var mat = fl.getDocumentDOM().viewMatrix;

document.width

Availability

Usage

document.width

Description
Property; an integer that specifies the width of the document (Stage) in pixels.

Example
The following example sets the width of the Stage to 400 pixels.

fl.getDocumentDOM().width= 400;
