copy(source, x, y, width, height, tx, ty, newWidth, newHeight, rotate, anchorX, anchorY, scaleX, scaleY, alpha, blendMode, roundPx) → {Phaser.BitmapData}

Copies a rectangular area from the source object to this BitmapData. If you give null as the source it will copy from itself. You can optionally resize, translate, rotate, scale, alpha or blend as it's drawn. All rotation, scaling and drawing takes place around the regions center point by default, but can be changed with the anchor parameters. Note that the source image can also be this BitmapData, which can create some interesting effects.

This method has a lot of parameters for maximum control. You can use the more friendly methods like copyRect and draw to avoid having to remember them all.

Parameters:

Name	Type	Argument	Default	Description
source	Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapData | Image | HTMLCanvasElement | string	<optional>		The source to copy from. If you give a string it will try and find the Image in the Game.Cache first. This is quite expensive so try to provide the image itself.

extract(destination, r, g, b, a, resize, r2, g2, b2) → {Phaser.BitmapData}

Scans this BitmapData for all pixels matching the given r,g,b values and then draws them into the given destination BitmapData. The original BitmapData remains unchanged. The destination BitmapData must be large enough to receive all of the pixels that are scanned unless the 'resize' parameter is true. Although the destination BitmapData is returned from this method, it's actually modified directly in place, meaning this call is perfectly valid: picture.extract(mask, r, g, b) You can specify optional r2, g2, b2 color values. If given the pixel written to the destination bitmap will be of the r2, g2, b2 color. If not given it will be written as the same color it was extracted. You can provide one or more alternative colors, allowing you to tint the color during extraction.

Parameters:

Name	Type	Argument	Default	Description
destination	Phaser.BitmapData			The BitmapData that the extracted pixels will be drawn to.
r	number			The red color component, in the range 0 - 255.
g	number			The green color component, in the range 0 - 255.
b	number			The blue color component, in the range 0 - 255.
a	number	<optional>	255	The alpha color component, in the range 0 - 255 that the new pixel will be drawn at.
resize	boolean	<optional>	false	Should the destination BitmapData be resized to match this one before the pixels are copied?
r2	number	<optional>		An alternative red color component to be written to the destination, in the range 0 - 255.
g2	number	<optional>		An alternative green color component to be written to the destination, in the range 0 - 255.
b2	number	<optional>		An alternative blue color component to be written to the destination, in the range 0 - 255.

The direction parameter controls from which direction it should start the scan:

0 = top to bottom 1 = bottom to top 2 = left to right 3 = right to left

load(source) → {Phaser.BitmapData}

Takes the given Game Object, resizes this BitmapData to match it and then draws it into this BitmapDatas canvas, ready for further processing. The source game object is not modified by this operation. If the source object uses a texture as part of a Texture Atlas or Sprite Sheet, only the current frame will be used for sizing. If a string is given it will assume it's a cache key and look in Phaser.Cache for an image key matching the string.

Parameters:

Name	Type	Description
source	Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapData | Image | HTMLCanvasElement | string	The object that will be used to populate this BitmapData. If you give a string it will try and find the Image in the Game.Cache first.

Returns:

Source - gameobjects/BitmapData.js, line 234

processPixel(callback, callbackContext, x, y, width, height) → {Phaser.BitmapData}

Scans through the area specified in this BitmapData and sends the color for every pixel to the given callback along with its x and y coordinates. Whatever value the callback returns is set as the new color for that pixel, unless it returns the same color, in which case it's skipped. Note that the format of the color received will be different depending on if the system is big or little endian. It is expected that your callback will deal with endianess. If you'd rather Phaser did it then use processPixelRGB instead. The callback will also be sent the pixels x and y coordinates respectively.

Parameters:

Name	Type	Argument	Default	Description
callback	function			The callback that will be sent each pixel color to be processed.
callbackContext	object			The context under which the callback will be called.
x	number	<optional>	0	The x coordinate of the top-left of the region to process from.
y	number	<optional>	0	The y coordinate of the top-left of the region to process from.
width	number	<optional>		The width of the region to process.
height	number	<optional>		The height of the region to process.

Returns:

Phaser.BitmapData -

This BitmapData object for method chaining.

Source - gameobjects/BitmapData.js, line 451

processPixelRGB(callback, callbackContext, x, y, width, height) → {Phaser.BitmapData}

Scans through the area specified in this BitmapData and sends a color object for every pixel to the given callback. The callback will be sent a color object with 6 properties: { r: number, g: number, b: number, a: number, color: number, rgba: string }. Where r, g, b and a are integers between 0 and 255 representing the color component values for red, green, blue and alpha. The color property is an Int32 of the full color. Note the endianess of this will change per system. The rgba property is a CSS style rgba() string which can be used with context.fillStyle calls, among others. The callback will also be sent the pixels x and y coordinates respectively. The callback must return either false, in which case no change will be made to the pixel, or a new color object. If a new color object is returned the pixel will be set to the r, g, b and a color values given within it.

Parameters:

Name	Type	Argument	Default	Description
callback	function			The callback that will be sent each pixel color object to be processed.

render() → {Phaser.BitmapData}

If the game is running in WebGL this will push the texture up to the GPU if it's dirty. This is called automatically if the BitmapData is being used by a Sprite, otherwise you need to remember to call it in your render function. If you wish to suppress this functionality set BitmapData.disableTextureUpload to true.

shadow(color, blur, x, y) → {Phaser.BitmapData}

Sets the shadow properties of this BitmapDatas context which will affect all draw operations made to it. You can cancel an existing shadow by calling this method and passing no parameters. Note: At the time of writing (October 2014) Chrome still doesn't support shadowBlur used with drawImage.

Parameters:

Name	Type	Argument	Default	Description
color	string			The color of the shadow, given in a CSS format, i.e. #000000 or rgba(0,0,0,1). If null or undefined the shadow will be reset.
blur	number	<optional>	5	The amount the shadow will be blurred by. Low values = a crisp shadow, high values = a softer shadow.
x	number	<optional>	10	The horizontal offset of the shadow in pixels.
y	number	<optional>	10	The vertical offset of the shadow in pixels.

shiftHSL(h, s, l, region) → {Phaser.BitmapData}

Shifts any or all of the hue, saturation and lightness values on every pixel in the given region, or the whole BitmapData if no region was specified. Shifting will add the given value onto the current h, s and l values, not replace them. The hue is wrapped to keep it within the range 0 to 1. Saturation and lightness are clamped to not exceed 1.

Parameters:

Name	Type	Argument	Default	Description
h	number	<optional>	null	The amount to shift the hue by.
s	number	<optional>	null	The amount to shift the saturation by.
l	number	<optional>	null	The amount to shift the lightness by.
region	Phaser.Rectangle	<optional>		The area to perform the operation on. If not given it will run over the whole BitmapData.

image	string | Image			The key of an image in the Phaser.Cache to use as the texture for this line, or an actual Image.
repeat	string	<optional>	'repeat-x'	The pattern repeat mode to use when drawing the line. Either repeat, repeat-x or no-repeat.
