# InterpolationMethod - AS3

Package | flash.display
Class | public final class InterpolationMethod
Inheritance | InterpolationMethod Object

Language Version: | ActionScript 3.0

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.

Constant Detail

### 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:

`InterpolationMethod.LINEAR_RGB` | `InterpolationMethod.RGB`
