Package net.paulhertz.pixelaudio

Class ImageTransform

java.lang.Object
net.paulhertz.pixelaudio.ImageTransform
public class ImageTransform extends Object
Deprecated.
THIS CLASS IS PROBABLY NOT GOING TO BE INCLUDED IN THE PixelAudio LIBRARY. USE BitmapTransform INSTEAD.

Provides static methods for rotating and reflecting Processing images of type PImage using a PGraphics instance. The PGraphics width and height affect scaling of the PImage. No-args constructor defaults to a 1024 x 1024 image size.

Most or all of the functionality required for the PixelAudo library is now in BitmapTransform. BitmapTransform's methods are faster and more generalized than those in ImageTransform, but they do not provide scaling or rotation by angles other than 90 degrees, nor do they tap into Processing's off-screen graphics environment.
