<td>
Creates a new PImage (the datatype for storing images). This provides a fresh buffer of pixels to play with. Set the size of the buffer with the <b>width</b> and <b>height</b> parameters. The <b>format</b> parameter defines how the pixels are stored. See the PImage reference for more information.
<br /> <br />
Be sure to include all three parameters, specifying only the width and height (but no format) will produce a strange error.
<br /> <br />
Advanced users please note that createImage() should be used instead of the syntax <tt>new PImage()</tt>.
