MaxComponent()

int MaxComponent

(

const Color &

)

Remarks

Returns the index of the component with the maximum absolute value.

Parameters:

const Color&

The color to check.

Returns

The index of the component with the maximum absolute value. r=0, g=1, b=2.

MinComponent()

int MinComponent

(

const Color &

)

Remarks

Returns the index of the component with the minimum absolute value

Parameters:

const Color&

The color to check.

Returns

The index of the component with the minimum absolute value. r=0, g=1, b=2.

MaxVal()

float MaxVal

(

const Color &

)

Remarks

Returns the value of the component with the maximum absolute value.

Parameters:

const Color&

The color to check.

Returns

The value of the component with the maximum absolute value.

MinVal()

float MinVal

(

const Color &

)

Remarks

The value of the component with the minimum absolute value.

Parameters:

const Color&

The color to check.

Returns

Length()

float Length ( const Color &  v )

inline

Remarks

Returns the 'length' of the color, i.e.

return (float)sqrt(v.r*v.r+v.g*v.g+v.b*v.b);

Parameters:

const Color& v

The color to return the length of.

Returns

The length of the color.
