|
* A BitmapData object contains a Canvas element to which you can draw anything you like via normal Canvas context operations.
|
|
* A single BitmapData can be used as the texture for one or many Images / Sprites.
|
|
* So if you need to dynamically create a Sprite texture then they are a good choice.
|
|
*
|
|
* Important note: Every BitmapData creates its own Canvas element. Because BitmapData's are now Game Objects themselves, and don't
|
|
* live on the display list, they are NOT automatically cleared when you change State. Therefore you _must_ call BitmapData.destroy
|
|
* in your State's shutdown method if you wish to free-up the resources the BitmapData used, it will not happen for you.

|
|
* @param {number} [x=0] - The x coordinate representing the top-left of the region to copy from the source image.
|
|
* @param {number} [y=0] - The y coordinate representing the top-left of the region to copy from the source image.
|
|
* @param {number} [width] - The width of the region to copy from the source image. If not specified it will use the full source image width.
|
|
* @param {number} [height] - The height of the region to copy from the source image. If not specified it will use the full source image height.
|
|
* @param {number} [tx] - The x coordinate to translate to before drawing. If not specified it will default to the `x` parameter. If `null` and `source` is a Display Object, it will default to `source.x`.
|
|
* @param {number} [ty] - The y coordinate to translate to before drawing. If not specified it will default to the `y` parameter. If `null` and `source` is a Display Object, it will default to `source.y`.
|
|
* @param {number} [newWidth] - The new width of the block being copied. If not specified it will default to the `width` parameter.
|
|
* @param {number} [newHeight] - The new height of the block being copied. If not specified it will default to the `height` parameter.
|
|
* @param {number} [rotate=0] - The angle in radians to rotate the block to before drawing. Rotation takes place around the center by default, but can be changed with the `anchor` parameters.
|
|
* @param {number} [anchorX=0] - The anchor point around which the block is rotated and scaled. A value between 0 and 1, where 0 is the top-left and 1 is bottom-right.
|
|
* @param {number} [anchorY=0] - The anchor point around which the block is rotated and scaled. A value between 0 and 1, where 0 is the top-left and 1 is bottom-right.
|
|
* @param {number} [scaleX=1] - The horizontal scale factor of the block. A value of 1 means no scaling. 2 would be twice the size, and so on.
|
|
* @param {number} [scaleY=1] - The vertical scale factor of the block. A value of 1 means no scaling. 2 would be twice the size, and so on.
|
|
* @param {number} [alpha=1] - The alpha that will be set on the context before drawing. A value between 0 (fully transparent) and 1, opaque.
|
|
* @param {string} [blendMode=null] - The composite blend mode that will be used when drawing. The default is no blend mode at all. This is a Canvas globalCompositeOperation value such as 'lighter' or 'xor'.
|
|
* @param {boolean} [roundPx=false] - Should the x and y values be rounded to integers before drawing? This prevents anti-aliasing in some instances.
