Class SPV_graphics.SPVGrint

java.lang.Object
   |
   +----SPV_graphics.SPVGrint

public class SPVGrint

extends Object

This class initializes the graphics process.

SPVGrint(int, int)

box(Graphics, double, double, double, double)

DrawRect that uses world coordinates rather than pixel coordinates.

ph2wh(int)

pixel height to world coordinate height

pw2ww(int)

pixel width to world coordinate width

setdiff(double, double)

This method sets the width and height of the world coordinate system.

setMarkerSize(double)

setdiff must be called before setMarkerSize.

setmin(double, double)

This method sets the minimum x and y values for the world coordinate system.

spvDrawLine(Graphics, double, double, double, double)

DrawLine that uses world coordinates rather than pixel coordinates.

wh2ph(double)

world height to pixel height

ww2pw(double)

world width to pixel width

xp2xw(int)

x pixel coordinates to world coordinates

xw2xp(double)

x world coordinates to pixel coordinates

yp2yw(int)

y pixel coordinates to world coordinates

yw2yp(double)

y world coordinates to pixel coordinates

 public SPVGrint(int width,
                 int height)

Parameters:

width - Width of the graphics component in pixels

height - Height of the graphics component in pixels

 public void setmin(double xmin,
                    double ymin)

This method sets the minimum x and y values for the world coordinate system. (xmin,ymin) is the lower left point in the world coordinate system.

Parameters:

xmin - Minimum x value in the world coordinate system

ymin - Minimum y value in the world coordinate system.

 public void setdiff(double xdiff,
                     double ydiff)

This method sets the width and height of the world coordinate system. (xmin+xdiff,ymin+ydiff) is the upper right point in the world coordinate system.

Parameters:

xdiff - Difference between the maximum and minimum x values in the world coordinate system

ydiff - Difference between the maximum and minimum y values in the world coordinate system

 public void setMarkerSize(double size)

setdiff must be called before setMarkerSize.

 public int xw2xp(double xwc)

x world coordinates to pixel coordinates

 public double xp2xw(int xpc)

x pixel coordinates to world coordinates

 public int yw2yp(double ywc)

y world coordinates to pixel coordinates

 public double yp2yw(int ypc)

y pixel coordinates to world coordinates

 public int ww2pw(double ww)

world width to pixel width

 public int wh2ph(double wh)

world height to pixel height

 public double pw2ww(int pw)

pixel width to world coordinate width

 public double ph2wh(int ph)

pixel height to world coordinate height

 public void spvDrawLine(Graphics g,
                         double x1,
                         double y1,
                         double x2,
                         double y2)

DrawLine that uses world coordinates rather than pixel coordinates.

Parameters:

g - The graphics context

x1 - The (world) x coordinate of the starting point

y1 - The (world) y coordinate of the starting point

x2 - The (world) x coordinate of the ending point

y2 - The (world) y coordinate of the ending point

 public void box(Graphics g,
                 double xmin,
                 double ymin,
                 double xmax,
                 double ymax)

DrawRect that uses world coordinates rather than pixel coordinates.

Parameters:

g - Graphics context

xmin - x coordinate of lower left corner

ymin - y coordinate of lower left corner

xmax - x coordinate of upper right corner

ymax - y coordinate of upper right corner
