Let me first introduce myself as it's the very first post on the forum -- my name is Lukasz, 33, Warsaw in Poland. It's been few months I've been tinkering with Processing; it's a great piece of software. Each day I catch myself thinking that human creativity has literally no boundaries.
The question follows.
There is a generated image, a noise map, for example, of size X vs Y. The size of the canvas is x vs y, where y<Y and x=X (the more generic question would be when x<X but it's not the case here).
The image is generated, row by row, from the very top, downwards, successively filling the canvas. What I would like to achieve is to scroll the image, moving up the top rows, so that the rows which are about to be created at the bottom of the canvas, would fill in the empty space. On a keypress, however, the system should save the *whole* image to the disk -- the image, mind you, would be of height greater that the height of the canvas.
