Runtime Versions: AIR 1.0 Flash Player 9

The InterpolationMethod class provides values for the interpolationMethod parameter in the Graphics.beginGradientFill() and Graphics.lineGradientStyle() methods. This parameter determines the RGB space to use when rendering the gradient.

LINEAR_RGB

Constant
public static const LINEAR_RGB:String = "linearRGB"

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Specifies that the linear RGB interpolation method should be used. This means that an RGB color space based on a linear RGB color model is used.

RGB

Constant 
public static const RGB:String = "rgb"

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Specifies that the RGB interpolation method should be used. This means that the gradient is rendered with exponential sRGB (standard RGB) space. The sRGB space is a W3C-endorsed standard that defines a non-linear conversion between red, green, and blue component values and the actual intensity of the visible component color.

For example, consider a simple linear gradient between two colors (with the spreadMethod parameter set to SpreadMethod.REFLECT). The different interpolation methods affect the appearance as follows:

linear gradient with InterpolationMethod.LINEAR_RGBlinear gradient with InterpolationMethod.RGB
InterpolationMethod.LINEAR_RGBInterpolationMethod.RGB
