Constructor Detail

ScalingGraphics

public ScalingGraphics(java.awt.Graphics realGraphics)
Method Detail

setScale

public void setScale(double newScale)
Sets the scale to be used for any subsequent drawing operations. All coordinates are multiplied by this value in both x- and y-direction before drawing. Thus, a value of 1.0 means no scaling, smaller values shrink the picture, larger ones enlarge it.

getScale

public double getScale()
Returns the scale factor currently used for drawing operations.
