<static> blendHardLight(a, b) → {integer}

Multiplies or screens the colors, depending on the source color value.

If the source color is lighter than 0.5, the backdrop is lightened, as if it were screened; this is useful for adding highlights to a scene.

If the source color is darker than 0.5, the backdrop is darkened, as if it were multiplied; this is useful for adding shadows to a scene.

The degree of lightening or darkening is proportional to the difference between the source color and 0.5; if it is equal to 0.5, the backdrop is unchanged.

Painting with pure black or white produces pure black or white. The effect is similar to shining a harsh spotlight on the backdrop.

Parameters:

Therefore, all blended pixels have red, green, and blue channel values of either 0 or 255. This changes all pixels to primary additive colors (red, green, or blue), white, or black.

Parameters:

Source - utils/Color.js, line 1094

<static> blendSoftLight(a, b) → {integer}

Darkens or lightens the colors, depending on the source color value.

If the source color is lighter than 0.5, the backdrop is lightened, as if it were dodged; this is useful for adding highlights to a scene.

If the source color is darker than 0.5, the backdrop is darkened, as if it were burned in. The degree of lightening or darkening is proportional to the difference between the source color and 0.5; if it is equal to 0.5, the backdrop is unchanged.

Painting with pure black or white produces a distinctly darker or lighter area, but does not result in pure black or white. The effect is similar to shining a diffused spotlight on the backdrop.

Parameters:

Name	Type	Description
`a`	integer	The source color to blend, in the range 1 to 255.
`b`	integer	The backdrop color to blend, in the range 1 to 255.

Source - utils/Color.js, line 1053

<static> blendVividLight(a, b) → {integer}

This blend mode combines Color Dodge and Color Burn (rescaled so that neutral colors become middle gray). Dodge applies when values in the top layer are lighter than middle gray, and burn to darker values. The middle gray is the neutral color. When color is lighter than this, this effectively moves the white point of the bottom layer down by twice the difference; when it is darker, the black point is moved up by twice the difference. The perceived contrast increases.

Parameters:

Name	Type	Description
`a`	integer	The source color to blend, in the range 1 to 255.
`b`	integer	The backdrop color to blend, in the range 1 to 255.

Returns:

<static> RGBtoString(r, g, b, a, prefix) → {string}

Converts the given color values into a string. If prefix was '#' it will be in the format #RRGGBB otherwise 0xAARRGGBB.

Parameters:

Name	Type	Argument	Default	Description
`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.
`prefix`	string	<optional>	'#'	The prefix used in the return string. If '#' it will return `#RRGGBB`, else `0xAARRGGBB`.

Returns:

string -

A string containing the color values. If prefix was '#' it will be in the format #RRGGBB otherwise 0xAARRGGBB.

Parameters:

Name	Type	Description
`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.

<static> unpackPixel(rgba, out, hsl, hsv) → {object}

Unpacks the r, g, b, a components into the specified color object, or a new object, for use with Int32Array. If little endian, then ABGR order is used when unpacking, otherwise, RGBA order is used. The resulting color object has the r, g, b, a properties which are unrelated to endianness.

Note that the integer is assumed to be packed in the correct endianness. On little-endian the format is 0xAABBGGRR and on big-endian the format is 0xRRGGBBAA. If you want a endian-independent method, use fromRGBA(rgba) and toRGBA(r, g, b, a).

Parameters:

Name	Type	Argument	Default	Description
`rgba`	number			The integer, packed in endian order by packPixel.
`out`	object	<optional>		An object into which 3 properties will be created: r, g and b. If not provided a new object will be created.
`hsl`	boolean	<optional>	false	Also convert the rgb values into hsl?
`hsv`	boolean	<optional>	false	Also convert the rgb values into hsv?

Returns:

object -

An object with the red, green and blue values set in the r, g and b properties.

<static> updateColor(out) → {number}

Takes a color object and updates the rgba property.

Parameters:

Name	Type	Description
`out`	object	The color object to update.

Returns:

number -

A native color value integer (format: 0xAARRGGBB).

<static> valueToColor(value, out) → {object}

Converts a value - a "hex" string, a "CSS 'web' string", or a number - into red, green, blue, and alpha components.

The value can be a string (see hexToColor and webToColor for the supported formats) or a packed integer (see getRGB).

An alpha channel is not supported when specifying a hex string.

Parameters:

Name	Type	Argument	Description
`value`	string \| number		The color expressed as a recognized string format or a packed integer.
`out`	object	<optional>	The object to use for the output. If not provided a new object will be created.

Returns:

object -

The (out) object with the red, green, blue, and alpha values set as the r/g/b/a properties.

Source - utils/Color.js, line 624

<static> webToColor(web, out) → {object}

Converts a CSS 'web' string into a Phaser Color object.

The web string can be in the format 'rgb(r,g,b)' or 'rgba(r,g,b,a)' where r/g/b are in the range [0..255] and a is in the range [0..1].

Parameters:

Name	Type	Argument	Description
`web`	string		The color string in CSS 'web' format.
`out`	object	<optional>	An object into which 4 properties will be created: r, g, b and a. If not provided a new object will be created.

Returns:

object -

An object with the red, green, blue and alpha values set in the r, g, b and a properties.
