Examples

Sync

import by.blooddy.crypto.PNG24Encoder;
var result:ByteArray = PNG24Encoder.encode( bytes, 100, 100, PNGFilter.NONE );

Async

import by.blooddy.crypto.PNG24Encoder;
import by.blooddy.crypto.events.ProcessEvent;

var png:PNG24Encoder = new PNG24Encoder();
png.encode( bytes, 100, 100, PNGFilter.NONE );
png.addEventListener( ProcessEvent.COMPLETE, function(event:ProcessEvent):void {
	var result:ByteArray = event.data;
	trace( result ); // async result
} );
png.addEventListener( ProcessEvent.ERROR, function(event:ProcessEvent):void {
	var error:Error = event.data;
	trace( error ); // async error
} );

Static Methods

Name	Description
`encode(image:BitmapData, filter:uint=0):ByteArray`	Creates a PNG-encoded byte sequence from the specified `BitmapData`. Used `BitmapData.encode()`, if posible.
`encodeBytes(bytes:ByteArray, width:uint, height:uint, filter:uint=0):ByteArray`	Creates a PNG-encoded byte sequence from the specified `ByteArray`.

Constructor

Name	Description
`PNG24Encoder()`	Creates a `PNG24Encoder` object.

Methods

Name	Description
`encode(image:BitmapData, filter:uint=0):ByteArray`	Asynchronously creates a PNG-encoded byte sequence from the specified `BitmapData`. Dispatched sequence of bytes in `ProcessEvent`.
`encodeBytes(bytes:ByteArray, width:uint, height:uint, filter:uint=0):ByteArray`	Asynchronously creates a PNG-encoded byte sequence from the specified `ByteArray`. Dispatched sequence of bytes in `ProcessEvent`.
