Chapter 14, Problem 8AW

Explanation of Solution

setScaleX method:

• The “setScaleX” method scales a node in its X dimension.
• It can be used to scale any node in scene graph.
• A “double” argument is passed to the method that denotes scaling factor.
• To retain node into original manner, both X and Y dimensions should be scaled same.
• If different values are used for X and Y dimensions then node will seem stretched.

Example:

The example for “setScaleX” method is given below:

Rectangle bx = new Rectangle(X, Y, W, H);

bx.setScaleX(0.5);

Here, “bx” denotes an object of “Rectangle” class. The values “X” and “Y” denotes coordinates of rectangle and “W” and “H” denotes width as well as height of rectangle respectively. The given code generates a rectangle with given dimensions and scales the rectangle at particular scale factor specified.

setScaleY method:

• The “setScaleY” method scales a node in its Y dimension.
• It can be used to scale any node in scene graph...
