Method Detail

adjustBrightness

()

method

public static function adjustBrightness(rgb:uint, brite:Number):uint

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Performs a linear brightness adjustment of an RGB color.

The same amount is added to the red, green, and blue channels of an RGB color. Each color channel is limited to the range 0 through 255.

Parameters

	`rgb:uint` — Original RGB color.

	`brite:Number` — Amount to be added to each color channel. The range for this parameter is -255 to 255; -255 produces black while 255 produces white. If this parameter is 0, the RGB color returned is the same as the original color.

Returns

uint — New RGB color.

adjustBrightness2

()

method

public static function adjustBrightness2(rgb:uint, brite:Number):uint

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Performs a scaled brightness adjustment of an RGB color.

Parameters

	`rgb:uint` — Original RGB color.

	`brite:Number` — The percentage to brighten or darken the original color. If positive, the original color is brightened toward white by this percentage. If negative, it is darkened toward black by this percentage. The range for this parameter is -100 to 100; -100 produces black while 100 produces white. If this parameter is 0, the RGB color returned is the same as the original color.

Returns

uint — New RGB color.

rgbMultiply

()

method

public static function rgbMultiply(rgb1:uint, rgb2:uint):uint

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Performs an RGB multiplication of two RGB colors.

This always results in a darker number than either original color unless one of them is white, in which case the other color is returned.

Parameters

	`rgb1:uint` — First RGB color.

	`rgb2:uint` — Second RGB color.

Returns

uint — RGB multiplication of the two colors.
