Quartz Composer


Quartz provides essential design services for applications in two primary parts: the Quartz 2D images API and the Quartz Extreme windowing environment. Quartz 2D’s abundant graphics capabilities derive from the Portable Doc Format (PDF) and provide professional-strength 2D graphics features such as Bezier curves, gradients and transformations. Acting as an advanced “visual mixing plank,” Quartz Extreme manages an application’s onscreen presentation and gives active, GPU-accelerated windows compositing with full support for transparency.
