DescriptionThis sample shows how to build a custom single source effect component for QuickTime. This effect uses a single source as input, and renders that source in greyscale. It also allows for a brightness value which can range from -100...0...100. A value of 0 signifies no change in brightness. This is a very basic sample and a good place to start if you've never looked at QuickTime effect code before. This sample makes use of some code from the Dimmer2 Effect Framework and Dimmer2 Effect is a recommended companion to this sample. It is however more complex, using multiple sources, multiple pixel formats, non-Macintosh support, tweens etc. For developers who have asked for a quick and dirty single source filter sample, this one's for you eh? CodeWarrior and Project Builder projects are included: - The CodeWarrior targets build a traditional PPC code resource, Carbon CFM component and a Carbon Mach-O component. The last two for Mac OS X only. - The Project Builder target will build a Mach-O dylib for Mac OS X.
