[w h format]
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 width and height parameters. The format parameter defines how the pixels are stored. See the PImage reference for more information. Possible formats: :rgb, :argb, :alpha (grayscale alpha channel) Prefer using create-image over initialising new PImage instances directly.

[img w h]
Resize the image to a new width and height. To make the image scale proportionally, use 0 as the value for the wide or high parameter. For instance, to make the width of an image 150 pixels, and change the height using the same proportion, use resize(150, 0). Even though a PGraphics is technically a PImage, it is not possible to rescale the image data found in a PGraphics. (It's simply not possible to do this consistently across renderers: technically infeasible with P3D, or what would it even do with PDF?) If you want to resize PGraphics content, first get a copy of its image data using the get() method, and call resize() on the PImage that is returned.
