scale

public void scale(double scale)

Symmetrically scales an image.

• If scale is less than 1 then the image will be reduced.
• If scale is 1, then nothing noticeable should happen to the image.
• If scale is more than 1 then the image will be bigger.

Parameters:

scale - scale quotient

scale

public void scale(double sx,
                  double sy)

Scales an image.

• If scaleX/Y is less than 1 then the image will be reduced.
• If scaleX/Y is 1, then nothing noticeable should happen to the image.
• If scaleX/Y is more than 1 then the image will be bigger.

Note: Scaling is not accumulative, it always refer to the original image.

Parameters:

sx - Horizontal scale

sy - Vertical scale
