AS3 Scale9 Bitmap


General:

AS3 Scale9 Bitmap is helper class that lets you create scale9 sprites with bitmap data fill - originally this was not possible in Flash 9. The helper class creates a "fake" scale 9 sprite containing 9 shapes that scale according to user-defined scaling matrix. Extremely useful for user interface work (creating buttons, scalable UI elements etc.).

Contents:

  • Scale9SimpleStateButton - class for creating resizing 1, 3 or 3 state buttons from bitmap data (skins);
  • Scale9SimpleBitmapSprite - class for creating static resizing UI elements from bitmap data (skins);
  • Example code (Flex Builder 3 project);

Requirements:

Actionscript 3

Demonstration 1:

Scale9SimpleStateButton (top left), Scale9SimpleBitmapSprite (top right) and original skin files (bottom row)

Demonstration 2:

UI elements created from a stylesheet using AS3 Scale9 Bitmap class, see this blog post for details.

Example Syntax:

PLAIN TEXT
Actionscript:
  1. var scale9_example:Rectangle = new Rectangle(6,6,105,20);
  2.            
  3. /* Initialize the button with all 3 states (normal, hover, down) using 3 different bitmaps */   
  4. var button_example:Scale9SimpleStateButton = new Scale9SimpleStateButton(
  5.     scale9_example,
  6.     button_skin_normal.bitmapData,
  7.     button_skin_hover.bitmapData,
  8.     button_skin_down.bitmapData
  9. );
  10.  
  11. /*
  12.   * Scale the button using "width" and "scaleY" properties
  13.   * (in general you can use "width", "height", "scaleY", "scaleX" properties for scaling)
  14.   */
  15.                 
  16. button_example.width = 300;
  17. button_example.scaleY = 2;
