Method Summary

void	begin()
void	defineColor(String nam, float r, float g, float b, float a)
void	defineColor(String nam, int R, int G, int B) In this defineColor implementation we're bad, because we ignore any colors that exceed our initial 128 colors limit. it would be fairly easy to use Vector for storage instead of fixed arrays, but well, there was no need for bigger color tables (yet).
void	drawArc(int x, int y, int width, int height, int startAngle, int arcAngle)
void	drawLine(int x1, int y1, int x2, int y2)
void	drawOval(int x, int y, int rx, int ry)
void	drawPolygon(int[] x, int[] y, int pts, boolean closed)
void	drawRect(int x1, int y1, int x2, int y2)
void	drawRoundRect(int x1, int y1, int x2, int y2, int dx, int dy)
void	drawString(String txt, int x, int y)
void	drawString(String txt, int x, int y, double ax, double ay) draw string with anchor point x,y where ax and ay translate the anchor relative to text extension.
void	drawString(String txt, int x, int y, double ax, double ay, double rot) addition: rot specifies rotation angle around the anchor. negative values additionally flip the text on the horizontal axis of the text.
void	drawString(String txt, int x, int y, int a) draw string with special attributes set (e.g. alignment etc.)
void	end()

PoGraSSgraphics

public PoGraSSgraphics(Graphics2D G,
                       int layer)

construct an instance of PoGraSS associated with a Graphics.

Parameters:

Method Detail

defineColor

public void defineColor(String nam,
                        int R,
                        int G,
                        int B)

In this defineColor implementation we're bad, because we ignore any colors that exceed our initial 128 colors limit. it would be fairly easy to use Vector for storage instead of fixed arrays, but well, there was no need for bigger color tables (yet).

Keep in mind, that the user can use any number of colors by using setColor(int,int,int). the defineColor principle is meant just to define a fixed set of few colors used frequently throughout the application.
