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;
