This class is extended to support different output devices (e.g. to a display window or PostScript file). Creating higher level graphics classes that utilize UCdriver methods enables the graphics output to be rendered on multiple output devices.
The input coordinates to the graphics routines are assumed to be in the "normalized" drawing range [0,1]x[0,1].

| UCdriver::UCdriver | ( | const char * | s = 0 |
) | [inline] |
Constructor, implements appropriate low level initialization for the graphics system.
The character string argument allows one to pass a name (such as a file name) to the initialization routines. There is a default definition for this constructor i.e. it is not a virtual function.
| s | A character string to be passed to initialization routine (e.g. a file name). |

| virtual UCdriver::~UCdriver | ( | ) | [inline, virtual] |
Destructor, shuts down, or cleans up, the graphics system.

| RGB | a three element double array with values between 0 and 255 specifying the red, green and blue components of the color. This parameter is only used if color == USER_RGB. |

| rotation | The rotation of the string about the reference point in a counterclockwise direction. The angle is specified in degrees. | |
| horiz_just | The horizontal alignment of the string about the reference point. A values of 0 causes the string to be horizontally centered about the reference point. A value of -1 causes the left edge of the string to be lined up with the reference point, a value of 1 lines up the right edge, and any other value the interpolation of these. For example, -0.5 causes the reference point to be located a forth of the string from the left edge of the string. Alignment is performed before any rotation. | |

For example, -0.5 causes the reference point to be located a forth of the string from the top edge of the string. Alignment is performed before any rotation. | |
