Classpublic class ImageLoader
InheritanceImageLoader Inheritance FeathersControl Inheritance starling.display.Sprite

Displays an image, either from an existing Texture object or from an image file loaded with its URL. Supported image files include ATF format and any bitmap formats that may be loaded by flash.display.Loader, including JPG, GIF, and PNG.

The following example passes a URL to an image loader and listens for its complete event:

     var loader:ImageLoader = new ImageLoader();
     loader.source = "http://example.com/example.png";
     loader.addEventListener( Event.COMPLETE, loader_completeHandler );
     this.addChild( loader );

The following example passes an existing texture to an image loader:

     var loader:ImageLoader = new ImageLoader();
     loader.source = Texture.fromBitmap( bitmap );
     this.addChild( loader );

Property Detail
colorproperty

delayTextureCreationproperty 
delayTextureCreation:Boolean

Determines if a loaded bitmap may be converted to a texture immediately after loading. If true, the loaded bitmap will be saved until this property is set to false, and only then it will be used to create the texture.

This property is intended to be used while a parent container, such as a List, is scrolling in order to keep scrolling as smooth as possible. Creating textures is expensive and performance can be affected by it. Set this property to true when the List dispatches FeathersEventType.SCROLL_START and set back to false when the List dispatches FeathersEventType.SCROLL_COMPLETE. You may also need to set to false if the isScrolling property of the List is true before you listen to those events.

In the following example, the image loader's texture creation is delayed:

         loader.delayTextureCreation = true;

The default value is false.


Implementation
    public function get delayTextureCreation():Boolean
    public function set delayTextureCreation(value:Boolean):void

Method Detail
autoSizeIfNeeded()method
protected function autoSizeIfNeeded():Boolean

If the component's dimensions have not been set explicitly, it will measure its content and determine an ideal size for itself. If the explicitWidth or explicitHeight member variables are set, those value will be used without additional measurement. If one is set, but not the other, the dimension with the explicit value will not be measured, but the other non-explicit dimension will still need measurement.

Calls setSizeInternal() to set up the actualWidth and actualHeight member variables used for layout.

Meant for internal use, and subclasses may override this function with a custom implementation.

Returns
Boolean
Event Detail
