Last Revision:
Version 1.0.1, 2005-07-26
Updated to produce a universal binary. No code changes were required.
Build Requirements:
Xcode 2.1, Xcode 1.0 or later.
Runtime Requirements:
Mac OS X 10.4.x or Mac OS X 10.3 (Panther) or later with QuickTime 6.4 or later.

ThreadExporter demonstrates importing and exporting still images in different formats on separate threads. QuickTime 6.4 (on MacOS X 10.3 and later) introduces several new features that support execution of background tasks on multiple threads in a preemptive multitasking environment. This makes it possible to offload many tasks from your program's main thread to forestall blocking the user interface. For more information see "Threaded Programming and QuickTime": http://developer.apple.com/documentation/QuickTime/WhatsNewQT6_4/Chap1/chapter_1_section_7.html Note: Xcode 2.1 project builds universal binary. This sample will not run on Mac OS X 10.2.x (Jaguar) even with QuickTime 6.4 or later.
