#X text 259 73 of.Image is a convenient object that lets you both draw
images to the screen and manipulate their pixel data. The ofImage allows
you to load/save an image from/to disk \, \, manipulate the pixels
\, and create an OpenGL texture that you can display on any shape with
texture coordinate. Loading a file into the ofImage allocates an ofPixels
object and creates the ofTexture to display the pixels. ofImage uses
a library called "freeImage" under the hood.;
