498 Printing
Example: Scaling, cropping, and
responding
In some cases, you may want adjust the size (or other properties) of a display object when
printing it to accommodate differences between the way it appears on screen and the way it
appears printed on paper. When you adjust the properties of a display object before printing
(for example, by using the
scaleX and scaleY properties), be aware that if the object scales
larger than the defined rectangle for the print area, the object will be cropped. You will also
probably want to reset the properties after the pages have been printed.
The following code scales the dimensions of the
txt display object (but not the green box
background), and the text field ends up being cropped by the dimensions of the specified
rectangle. After printing, the text field is returned to its original size for display on screen. If
the user cancels the print job from the operating system’s Print dialog box, the content in the
Flash Player changes to alert the user that the job has been canceled.
