Constructor Detail

PlayFieldGraphic

public PlayFieldGraphic()

Method Detail

setScale

public static void setScale(double newScale)

Set the zooming factor of the graphics to be drawn

Parameters:

newScale - New scale

getScale

public static double getScale()

Returns the currently used scaling factor

Returns:

The scaling factor

draw

public abstract void draw(java.awt.Graphics2D g2)

Draws the graphic component to the graphics context g2

Parameters:

g2 - The context to draw the graphics to

scale

public static int scale(double value)

Scales the value according to current zoom level

Parameters:

value - Value to scale

Returns:

Scaled value bit-truncated (casted) to an integer

scale

public static int scale(int value)

Scales the value according to current zoom level

Parameters:

value - Value to scale

Returns:

Scaled value bit-truncated (casted) to an integer

invScale

public static double invScale(double value)

Performs an inverse of the scaling procedure with current scale. NOTE: invScale(scale(value)) != value because of rounding to integer at scale() -methods

Parameters:

value - The value to inverse-scale

Returns:

Inverse-scaled value
