void swri_image_util::JetColorMap(unsigned char &r, unsigned char &g, unsigned char &b, float value, float min, float max)

Map a scalar value to a color gradient.

Return a color gradient RGB value by mapping an input value to a specified scale.

Parameters:

• r – [out] Red channel of the output gradient color.

• g – [out] Green channel of the output gradient color.

• b – [out] Blue channel of the output gradient color.

• value – [in] The input value to be mapped to a color.

• min – [in] The minimum value on the gradient scale.

• max – [in] The maximum value on the gradient scale.
