Encodes image data using JPEG compression algorithm.

Name	Value
Package	`by.blooddy.crypto.image`
Name	`final class JPEGEncoder`
Inheritance	`JPEGEncoder` → Process → `EventDispatcher` → `Object`

Examples

Sync

import by.blooddy.crypto.Base64;
var result:ByteArray = Base64.decode( 'ZWFzdXJlLg==' );

Async

import by.blooddy.crypto.JPEGEncoder;
import by.blooddy.crypto.events.ProcessEvent;

var jpeg:JPEGEncoder= new JPEGEncoder();
jpeg.decode( bytes );
jpeg.addEventListener( ProcessEvent.COMPLETE, function(event:ProcessEvent):void {
	var result:ByteArray = event.data;
	trace( result ); // async result
} );
jpeg.addEventListener( ProcessEvent.ERROR, function(event:ProcessEvent):void {
	var error:Error = event.data;
	trace( error ); // async error
} );

Static Methods

Name	Description
`encode(image:BitmapData, quality:uint=60):ByteArray`	Creates a JPEG image from the specified `BitmapData`. Used `BitmapData.encode()`, if posible.
`encodeBytes(bytes:ByteArray, width:uint, height:uint, quality:uint=60):ByteArray`	Creates a JPEG image from the specified `ByteArray`.

Name	Description
`function JPEGEncoder()`	Creates a `JPEGEncoder` object.

Methods

Name	Description
`encode(image:BitmapData, quality:uint=60):ByteArray`	Asynchronously creates a JPEG image from the specified `BitmapData`. Dispatched sequence of bytes in `ProcessEvent`.
`encodeBytes(bytes:ByteArray, width:uint, height:uint, quality:uint=60):ByteArray`	Asynchronously creates a JPEG image from the specified `ByteArray`. Dispatched sequence of bytes in `ProcessEvent`.
