method
public function encodeByteArray(byteArray:ByteArray, width:int, height:int, transparent:Boolean = true):ByteArray
Language Version :
ActionScript 3.0
Product Version :
Flex 3
Runtime Versions :
Flash Player 9, AIR 1.1
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.
Parameters
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) — If false, alpha channel information
is ignored but you still must represent each pixel
as four bytes in ARGB format.
Returns
ByteArray — Returns a ByteArray object containing PNG-encoded image data.
