## CONSTRUCTOR & DESTRUCTOR DOCUMENTATION

### SDLmm::ColorRGBA::ColorRGBA ()` [inline]`

Default constructor which creates an empty **ColorRGBA** (rgb variables set to zero).

### SDLmm::ColorRGBA::ColorRGBA (const ColorRGBA & color)` [inline]`

This is the copy constructor. Simply initializes the value of an **ColorRGBA** to that of another **ColorRGBA**.

**Parameters:**

- *color*

  *an existing* **ColorRGBA** *object.*

### SDLmm::ColorRGBA::ColorRGBA (Uint8 nr, Uint8 ng, Uint8 nb, Uint8 na)` [inline]`

*Constructor which initializes the class from integer values.*

**Parameters:**

- *nr, red*

  *component*

- *ng, green*

  *component*

- *nb, blue*

  *component*

- *na, alpha*

  *component*

## MEMBER FUNCTION DOCUMENTATION

### ColorRGBA & SDLmm::ColorRGBA::operator= (const ColorRGBA & color)` [inline]`

*Set the value of an* **ColorRGBA** *to that of an existing* **ColorRGBA***.*

### bool SDLmm::ColorRGBA::operator== (const ColorRGBA & color) const` [inline]`

*Compare two colors for equality.*

**Returns:**  *true if coordinates are identical in both colors.*
