public LinearColorInterpolator(ColorSpace colorSpace)
interpolate
public Color interpolate(Color a,
Color b,
float mixing)
- Interpolates to a color between a and b
- Specified by:
interpolate
in interface ColorInterpolator
- Parameters:
a
- First colorb
- Second colormixing
- Mixing coefficient; the fraction of a in the result.
- Returns:
- The color between a and b
- Throws:
IllegalArgumentException
- if mixing is not between 0 and 1- See Also:
ColorInterpolator.interpolate(java.awt.Color, java.awt.Color, float)
setColorSpace
public void setColorSpace(ColorSpace colorSpace,
LinearColorInterpolator.InterpolationDirection[] dir)
- Sets the ColorSpace to use for interpolation.
The most common scheme for color spaces is to use linear components
between 0 and 1 (for instance red,green,blue). For such a component, a
linear interpolation between two colors is used.
Sometimes a component may be in cylindrical coordinates. In this case,
the component can be mapped in a number of ways. These are set by
InterpolationDirections.
- Parameters:
colorSpace
- The color space for interpolationinterpDirection
- An array of size colorSpace.getNumComponents()
giving the interpolation direction for each component.
