Korf's paper: Optimal Rectangle Packing: Initial Results. The basic algorithm for packing rectangles into an enclosing rectangle of minimum size is described in, for example, Richard E. So the rest of this article focuses on a solution that does minimize wasted space when the rectangles are of varying width and height, and that is also reasonably fast and simple. However, these solutions leave a lot of wasted space when the rectangles are of varying width and height. This is also very simple and fast, and would actually be optimal if all rectangles had the same width.

There are a few trivial solutions on how to pack rectangles into an enclosing rectangle:

Full instructions are provided on the form. You'll see a form with various parameters - it's easiest to run it with the default values first and then experiment a bit.

Software interface to the rectangle packer.Placing rectangles in a given enclosing rectangle without overlapping other rectangles.That way I know people appreciate my work. Oh, by the way, if you like this article, please vote for it. Note that it isn't guaranteed to generate the absolute best enclosing rectangle every time, because that would take a lot longer. The rectangle packing algorithm described in this article is designed to do this relatively quickly so it can be used to generate sprites on the fly, and to do a reasonable job of finding the smallest enclosing rectangle. It than becomes a matter of finding the enclosing rectangle with the smallest area (width x height) in which you can pack all the rectangles. To simplify things a bit, you can think of the images as rectangles, and of the sprite as an enclosing rectangle. However, that means you want a fast algorithm to generate the sprite, even if you cache the result for subsequent page loads.Īdditionally, you want the algorithm to pack the images in the sprite in a way that minimizes the overall size of the sprite - the smaller the size, the less time it takes the browser to load the sprite and the less bandwidth you incur: Much better to have the sprite generated automatically, ideally on the fly when the page loads. But then each time you add or remove an image, you have to manually redo the sprite. It would definitely be possible to combine the images manually with a graphics program.

This technique is further described in chapter 12 of my book ASP.NET Site Performance Secrets. Using some CSS, you can make the individual images contained within the sprite appear on the page individually. This way, you prevent the overhead of the browser having to request each individual image from the server one by one, which can be significant when loading lots of small images. With this technique, instead of loading all images on the page one by one, you combine them into a single larger image - called a sprite - and load that in one go. Having an algorithm like this is important when generating CSS Sprites, which are used to speed up image loading when loading a web page. An implementation of the algorithm is in the download, along with a web site that graphically shows step by step how the algorithm arrives at the optimal enclosing rectangle.

This article describes a fast algorithm to pack a series of rectangles of varying widths and heights into a single enclosing rectangle, with no overlap and in a way that minimizes the amount of wasted space in the enclosing rectangle.
