C# Class SharpMap.Rendering.Thematics.ColorBlend

Defines arrays of colors and positions used for interpolating color blending in a multicolor gradient.

Public Methods

Method	Description
ColorBlend ( System colors, float positions ) : System	Initializes a new instance of the ColorBlend class.
GetColor ( float pos ) : Color	Gets the color from the scale at position 'pos'. If the position is outside the scale [0..1] only the fractional part is used (in other words the scale restarts for each integer-part).
ThreeColors ( System fromColor, System middleColor, System toColor ) : ColorBlend	Creates a linear gradient scale from three colors
ToBrush ( Rectangle rectangle, float angle ) : LinearGradientBrush	Converts the color blend to a gradient brush
TwoColors ( System fromColor, System toColor ) : ColorBlend	Creates a linear gradient scale from two colors

Method	Description
ColorBlend ( ) : System

Initializes a new instance of the ColorBlend class.

public ColorBlend ( System colors, float positions ) : System
colors	System	An array of Color structures that represents the colors to use at corresponding positions along a gradient.
positions	float	An array of values that specify percentages of distance along the gradient line.
return	System

Gets the color from the scale at position 'pos'.

If the position is outside the scale [0..1] only the fractional part is used (in other words the scale restarts for each integer-part).

public GetColor ( float pos ) : Color
pos	float	Position on scale between 0.0f and 1.0f
return	System.Drawing.Color

Creates a linear gradient scale from three colors

public static ThreeColors ( System fromColor, System middleColor, System toColor ) : ColorBlend
fromColor	System
middleColor	System
toColor	System
return	ColorBlend

Converts the color blend to a gradient brush

public ToBrush ( Rectangle rectangle, float angle ) : LinearGradientBrush
rectangle	Rectangle
angle	float
return	System.Drawing.Drawing2D.LinearGradientBrush

Creates a linear gradient scale from two colors

public static TwoColors ( System fromColor, System toColor ) : ColorBlend
fromColor	System
toColor	System
return	ColorBlend
