Parameters

startPoint  PointF

The starting point of the gradient.

endPoint  PointF

The end point of the gradient.

startColor  ColorF

The starting color of the gradient.

endColor  ColorF

The end color of the gradient.

wrapMode  GradientWrapMode  (Optional)

Determines how the gradient is treated outside the gradient area. This parameter is optional.
Default value: Stop.

workingColorSpace  WorkingColorSpace  (Optional)

Determines the color space in which the gradient is calculated. This parameter is optional.
Default value: Default, which means Linear for this overload.

Return Value

This overload creates a gradient with fix coordinates. To automatically apply the gradient to the bounds of each Path, use the overloads with an angle parameter, such as the CreateLinearGradient(Single, Color32, Color32, WorkingColorSpace) overload.

The workingColorSpace parameter affects only the color interpolation, not the blending with the background, which is determined by the color space of the target bitmap data (or by DrawingOptions.Quantizer, if specified).

In this overload the default value of workingColorSpace maps to WorkingColorSpace.Linear, because the ColorF type represents a color in the linear color space. When creating a monochromatic gradient, specifying Srgb can be better, because then the perceived mid-tone brightness will be at the middle of the gradient. Otherwise, using Linear may be more appropriate, so the transition between the colors will seem more "natural".
