Constructor & Destructor Documentation

FMColor::FMColor (   )  [inline]

Creates an empty FMColor. The default values are non deterministic.

FMColor::FMColor (  uint8  _r, uint8  _g, uint8  _b, uint8  _a = 255 )  [inline]

Creates the FMColor with the coordinates values. The first three coordinates are taken from the FMVector3, where the first one is the x value, the second is that y, and the third is the z. The forth value is the float specified. Parameters: _r  The red value. _g  The green value. _b  The blue value. _a  The alpha value.

FMColor::FMColor (  uint32  hex  )  [inline]

Creates the FMColor from a color encoded into a uint32. The most significant byte makes up the red value. The second most significant makes up the green value, the third the blue, and the forth the alpha. Parameters: hex  The uint to decode the color values from.

FMColor::FMColor (  const float *  components, uint32  componentCount )

Creates the FMColor from a list of floats. It creates the FMColor with the values specified in the floats, which range from 0.0f to 1.0f. componentCount is used to determined how many values to take from the float array. If there are insufficient values, then it will give the remaining values default values. The default values are 0 for the colors and 255 for the alpha. It fills in the values in this order: red, green, blue, alpha. Parameters: components  The float array to get values from. componentCount  The amount of float to take from the array.

FMColor::FMColor (  const FMVector3 &  v  )

Creates a color value from a 3D vector. The alpha value of the color is set to the default of 255 (1.0f). Parameters: v  The 3D vector representing the color value.

FMColor::FMColor (  const FMVector4 &  v  )

Creates a color value from a 4D vector. Parameters: v  The 4D vector representing the color value.

Member Function Documentation

uint8 FMColor::ComponentAverage (   )  [inline]

Get the average of the three color values of this FMColor. Returns: The averages of the three colors values of this FMColor.

FMColor::operator uint8 * (   )  [inline]

Get this FMColor as an array of uint8s. Returns: The uint8 array.

void FMColor::ToFloats (  float *  components, uint32  componentCount )

Get this FMColor as an array of floats. It fills the first componentCount elements (max 4) of components with the red, green, blue, alpha values of this FMColor in that order. Parameters: components  The float array to fill. componentCount  The amount of float to fill into the array.
