Method Details

isInterpolationInPremul

public boolean isInterpolationInPremul()

See Also:

• setInterpolationInPremul(boolean)

setInterpolationInPremul

public GradientShader.Builder setInterpolationInPremul(boolean interpolationInPremul)

If false, gradients will interpolate their colors in unpremul space and then premultiply each of the results. If true, gradients will premultiply their colors first, and then interpolate between them.

Interpolating colors using the premultiplied representations tends to produce more attractive transitions than the non-premultiplied representations, particularly when transitioning from a fully opaque color to fully transparent.

The default is true to match CSS requirements.

Parameters:

interpolationInPremul - whether interpolate colors in premul space

getInterpolationColorSpace

@NonNull
public GradientShader.InterpolationColorSpace getInterpolationColorSpace()

See Also:

• setInterpolationColorSpace(InterpolationColorSpace)

setInterpolationColorSpace

public GradientShader.Builder setInterpolationColorSpace(@NonNull
 GradientShader.InterpolationColorSpace interpolationColorSpace)

Set the color space for interpolation.

The default is GradientShader.InterpolationColorSpace.DESTINATION.

getHueInterpolationMethod

@NonNull
public GradientShader.HueInterpolationMethod getHueInterpolationMethod()

See Also:

• setHueInterpolationMethod(HueInterpolationMethod)

setHueInterpolationMethod

public GradientShader.Builder setHueInterpolationMethod(@NonNull
 GradientShader.HueInterpolationMethod hueInterpolationMethod)

For color functions with a hue angle (LCH, HSL, HWB etc.), this specifies a way to interpolate hue values.

The default is GradientShader.HueInterpolationMethod.SHORTER.
