public function encode(bitmapData:BitmapData):ByteArray
Converts the pixels of a BitmapData object to a PNG-encoded ByteArray object.
Parâmetros
bitmapData:BitmapData — The input BitmapData object.
|

| encodeByteArray | () | método |
public function encodeByteArray(byteArray:ByteArray, width:int, height:int, transparent:Boolean = true):ByteArray
Converts a ByteArray object containing raw pixels in 32-bit ARGB (Alpha, Red, Green, Blue) format to a new PNG-encoded ByteArray object. The original ByteArray is left unchanged.
Parâmetros
byteArray:ByteArray — The input ByteArray object containing raw pixels.
This ByteArray should contain
4 width height bytes.
Each pixel is represented by 4 bytes, in the order ARGB.
The first four bytes represent the top-left pixel of the image.
The next four bytes represent the pixel to its right, etc.
Each row follows the previous one without any padding.
|
|
width:int — The width of the input image, in pixels.
|
|
height:int — The height of the input image, in pixels.
|
|
transparent:Boolean (default = true)false, alpha channel information
is ignored but you still must represent each pixel
as four bytes in ARGB format.
