ImageSnapshot

패키지	mx.graphics
클래스	public dynamic class ImageSnapshot
상속	ImageSnapshot Object

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

A helper class used to capture a snapshot of any Flash component that implements flash.display.IBitmapDrawable, including Flex UIComponents.

An instance of this class can be sent as a RemoteObject to Adobe's LiveCycle Data Services to generate a PDF file of a client-side image. If you need to specify additional properties of the image beyond its contentType, width, and height properties, you should set name/value pairs on the properties object.

In earlier versions of Flex, you set these additional properties on the ImageSnapshot instance itself. This class is still dynamic in order to allow that, but in a future version of Flex it might no longer be dynamic.

An Object containing name/value pairs specifying additional properties of the image.

You generally supply such information only when sending an ImageSnapshot instance to Adobe's LiveCycle Data Services in order to generate a PDF file. You can either set the entire object or set individual name/value pairs on the pre-existing empty Object.

생성자

public function ImageSnapshot(width:int = 0, height:int = 0, data:ByteArray = null, contentType:String = null)

언어 버전:

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

Constructor.

매개 변수

	`width:int` (default = `0`) — Width of the image.

	`height:int` (default = `0`) — Height of the image.

	`data:ByteArray` (default = `null`) — A byte array to contain the image.

	`contentType:String` (default = `null`) — The encoder format type for the image, either PNGEncoder or JPEGEncoder.

captureBitmapData

()

메서드

 public static function captureBitmapData(source:IBitmapDrawable, matrix:Matrix = null, colorTransform:flash.geom:ColorTransform = null, blendMode:String = null, clipRect:Rectangle = null, smoothing:Boolean = false):BitmapData

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

A utility method to grab a raw snapshot of a UI component as BitmapData.

매개 변수

	`source:IBitmapDrawable` — An object that implements the `flash.display.IBitmapDrawable` interface.

	`matrix:Matrix` (default = `null`) — A Matrix object used to scale, rotate, or translate the coordinates of the captured bitmap. If you do not want to apply a matrix transformation to the image, set this parameter to an identity matrix, created with the default new Matrix() constructor, or pass a null value.

	`colorTransform:flash.geom:ColorTransform` (default = `null`) — A ColorTransform object that you use to adjust the color values of the bitmap. If no object is supplied, the bitmap image's colors are not transformed. If you must pass this parameter but you do not want to transform the image, set this parameter to a ColorTransform object created with the default new ColorTransform() constructor.

	`blendMode:String` (default = `null`) — A string value, from the flash.display.BlendMode class, specifying the blend mode to be applied to the resulting bitmap.

	`clipRect:Rectangle` (default = `null`) — A Rectangle object that defines the area of the source object to draw. If you do not supply this value, no clipping occurs and the entire source object is drawn.

	`smoothing:Boolean` (default = `false`) — A Boolean value that determines whether a BitmapData object is smoothed when scaled.

반환값

BitmapData — A BitmapData object representing the captured snapshot or null if the source has no visible bounds.

captureImage

()

메서드

 public static function captureImage(source:IBitmapDrawable, dpi:Number = 0, encoder:IImageEncoder = null, scaleLimited:Boolean = true):ImageSnapshot

언어 버전:

ActionScript 3.0

제품 버전:

Flex 3

런타임 버전:

Flash Player 9, AIR 1.1

A utility method to grab a snapshot of a component, scaled to a specific resolution (in dpi) and encoded into a specific image format.

매개 변수

	`source:IBitmapDrawable` — An object that implements the `flash.display.IBitmapDrawable` interface.

	`dpi:Number` (default = `0`) — The resolution in dots per inch. If a resolution is not provided, the current on-screen resolution is used by default.

	`encoder:IImageEncoder` (default = `null`) — The image format used to encode the raw bitmap. The two encoders are PNGEncoder and JPEGEncoder. If an encoder is not provided, the default is PNGEncoder.

	`scaleLimited:Boolean` (default = `true`) — The maximum width or height of a bitmap in Flash is 2880 pixels - if scaleLimited is set to true the resolution will be reduced proportionately to fit within 2880 pixels, otherwise, if scaleLimited is false, smaller snapshot windows will be taken and stitched together to capture a larger image. The default is true.
