方法詳細資訊

getSnapshot

()

方法

 public static function getSnapshot(target:IUIComponent, visibleBounds:Rectangle = null, propagateColorTransform:Boolean = false):BitmapData

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

Creates a BitmapData representation of the target object.

參數

	`target:IUIComponent` — The object to capture in the resulting BitmapData

	`visibleBounds:Rectangle` (default = `null`) — If non-null, this Rectangle will be populated with the visible bounds of the object, relative to the object itself.

	`propagateColorTransform:Boolean` (default = `false`) — If true, the target's color transform will be applied to the bitmap capture operation.

傳回值

BitmapData — A BitmapData object containing the image.

擲回值

SecurityError — The target object and all of its child objects do not come from the same domain as the caller, or are not in a content that is accessible to the caller by having called the Security.allowDomain() method.

getSnapshotWithPadding

()

方法

 public static function getSnapshotWithPadding(target:IUIComponent, padding:int = 4, propagateColorTransform:Boolean = false, bounds:Rectangle = null):BitmapData

語言版本:

ActionScript 3.0

產品版本:

Flex 4

執行階段版本:

Flash Player 10, AIR 1.5

Creates a BitmapData representation of the target object.

參數

	`target:IUIComponent` — The object to capture in the resulting BitmapData

	`padding:int` (default = `4`) — Padding, in pixels, around to target to be included in the bitmap.

	`propagateColorTransform:Boolean` (default = `false`) — If true, the target's color transform will be applied to the bitmap capture operation.

	`bounds:Rectangle` (default = `null`) — If non-null, this Rectangle will be populated with the visible bounds of the object, relative to the object itself.

傳回值

BitmapData — A BitmapData object containing the image.
