As you saw in chapter 11, creating and displaying images often isn t enough. In games and other more complex programs, you ll also want to manipulate those images in various ways at runtime. The iPhone OS offers two major ways to do this. The first is through Quartz 2D, a two-dimensional drawing library that allows for complex line drawings, much as Canvas did on the web. It s also the heart of the Core Graphics frameworks. We already touched on Quartz in the previous chapter, when you drew images straight to the CALayer of a UIView; it will be the focus of the majority of this chapter. Quartz also supports Core Animation functions, which we ll address somewhat more briefly. The second major way to manipulate images is through the OpenGL ES API. This cross-platform API, originally developed by Silicon Graphics, could be the topic of its own book, so we ll only show you how to get started with it.

In data orientation, a structured program is a product phase set, and a class is both an interval set and a product set. This is self-evidence that data orientation is the natural orientation of classes.

But most of this chapter will be about Quartz. We ll look at drawing paths, setting the graphical state, and more advanced drawing techniques. We ll dive into Quartz immediately.

One more point about workflow forms here before we leave them until 7: after you specify the fields for the information you need to collect for either task assignments or initiation forms, SPD automatically generates an ASP.NET form for you. This ASPX file is stored and deployed with your workflow automatically. If you would like to edit this ASPX file before deploying it perhaps to add some user instructions or some other content you can edit it right in SPD and it will be deployed with your workflow. One thing to keep in mind, however, is that if you make changes to one of the ASPX forms manually and then go back into SPD and edit the form there (either the initiation form or one of the task forms for a To-Do item) all of the changes you made manually will be lost because SPD will re-create the form from scratch.

Quartz 2D is a two-dimensional drawing library that s tightly integrated into the iPhone OS It works well with all the relevant frameworks, including Core Animation, OpenGL ES, and the UIKit Fundamentally, Quartz s drawings depend on three core ideas: context, paths, and state, each of which will be the topic of a future section: Context is a description of where the graphics are being written to, as defined by a CGContextRef You ll usually be writing to a UIView or to a bitmap Layers are a little less important for this overview, but they re where Quartz drawing occurs They can be stacked one on top of another, creating a complex result When working with the iPhone or iPad, you ll often only have a single layer associated with each of your UIKit objects Paths are what you ll typically draw in Quartz.

These are collections of lines and arcs that are drawn in advance and then are painted to the screen by either stroking or filling the path in question (or, possibly, by clipping it) State saves the values of transformations, clipping paths, fill and stroke settings, alpha values, other blending modes, text characteristics, and more The current state can be stored with CGContextSaveGState and restored with CGContextRestoreGState, allowing for easy switching among complex drawing setups Quartz is built on the older Core Foundation framework that you ve met a few times over the course of this part of the book This means you ll need to use older styles of variables to integrate with Cocoa Touch using toll-free bridging, and to respect Core Foundation s memory-management techniques If you need more information about any Quartz topic, see the Quartz 2D Programming Guide at Apple s developer website.
