Apple Inc., formerly Apple Computer, Inc., is an American multinational corporation headquartered in Cupertino, California, that designs, develops, and sells consumer electronics, computer software and personal computers.
In image processing, a technique for processing the alpha channel of a pixel. Instead of performing the alpha blend for each pixel, the alpha value is premultiplied to each of the other colour channel values for that pixel. The pixel can then be interpreted as is from then on because all of the colour channel values have been appropriately changed to reflect the alpha component.
Industry:Software; Computer
A window without an offscreen buffer for screen pixel values.
Industry:Software; Computer
In Mach, a message that contains either a reference to a port or a pointer to data. Compare simple message.
Industry:Software; Computer
A fill rule that determines when to paint a pixel. The outcome depends on the direction that path segments are drawn. Compare with even-odd rule.
Industry:Software; Computer
A programmatic mechanism for alerting interested recipients (observers) that some event has occurred during programme execution. The observers can be users, other processes, or even the same process that originates the notification. In Mac OS X, the term is used to identify specific mechanisms that are variations of the basic meaning. In the kernel environment, notification is sometimes used to identify a message sent via IPC from kernel space to user space. Distributed notifications provide a way for a process to broadcast an alert (along with additional data) to any other process that makes itself an observer of that notification. Finally, the Notification Manager (a Carbon manager) lets background programmes notify users—through blinking icons in the menu bar, by sounds, or by dialogs—that their intercession is required. In Enterprise Objects, it’s a mechanism that provides an asynchronous communication infrastructure between objects.
Industry:Software; Computer
A special Mach port that is part of a task. A task’s notify port receives messages from the kernel advising the task of changes in port access rights and of the status of messages it has sent.
Industry:Software; Computer
WebObjects class that encapsulates format properties for an NSXMLOutputStream object.
Industry:Software; Computer
WebObjects class that serialises objects and data into XML documents.
Industry:Software; Computer
An I/O Kit object that represents a detected, controllable entity such as a device or logical service. A nub may represent a bus, disk, graphics adaptor, or any number of similar entities. A nub supports dynamic configuration by providing a bridge between two drivers (and, by extension, between two families). A nub can also provide services to code running in user space through a device interface. See also device, driver
