    • Facilities are provided within an operating system for supporting deferred printing of print jobs. The process of spooling a print job and the process of despooling the print job are decoupled, such that a printer need not be available at the time of spooling. Print jobs are spooled in a device-independent format, such as the enhanced metafile format. The print jobs may be spooled without a printer driver being installed for a target printer or without the target printer being connected to the system. Later, when the target printer becomes available, the print job is despooled and printed. A configuration database holds different printer configurations that list available printers in different environments. For example, a user may have a different configuration for printers available when he uses his computer at home, at work and on the road, respectively. The configurations help the user to identify the printers that are currently available and those that are available in other settings. When a currently active machine configuration changes, the system checks for spooled jobs on printers that were previously unavailable and are now available and asks the user if the user wishes to start printing these spooled print jobs.
    • 在操作系统中提供设备,以支持打印作业的延期打印。 打印作业的后台处理和打印作业的分离过程被解耦,使得打印机在假脱机时不需要可用。 打印作业以与设备无关的格式假脱机,例如增强的图元文件格式。 无需为目标打印机安装打印机驱动程序,或者目标打印机未连接到系统,打印作业可能会被假脱机。 之后,当目标打印机变得可用时,打印作业被去除和打印。 配置数据库保存不同的打印机配置,列出不同环境中的可用打印机。 例如,当用户在家中,在工作中和在道路上分别使用他的计算机时,用户可能具有不同的可用打印机配置。 配置帮助用户识别当前可用的打印机以及其他设置中可用的打印机。 当当前活动的机器配置更改时,系统将检查以前不可用并且现在可用的打印机上的假脱机作业,并询问用户是否希望开始打印这些假脱机打印作业。

    • Hybrid image format techniques are described in which multiple resolution images are concatenated to a standard bitmap image to create a hybrid image file. The hybrid image file is created through combining a relatively low resolution image with the additional images in a multi-frame format having higher resolution. The hybrid image file may contain data detectable to signal that higher resolution images are available in the hybrid image file. A hybrid aware application may be configured to detect and output a higher resolution image from the hybrid image file based on detection of the data. A legacy application that is not configured to detect the data may be unaware of higher resolution images contained in the hybrid image file, and accordingly outputs the relatively low resolution image.
    • 描述混合图像格式技术,其中多个分辨率图像被连接到标准位图图像以创建混合图像文件。 通过将相对低分辨率的图像与具有更高分辨率的多帧格式的附加图像组合来创建混合图像文件。 混合图像文件可以包含可检测的数据,以指示混合图像文件中更高分辨率图像可用。 混合感知应用可以被配置为基于对数据的检测从混合图像文件检测和输出更高分辨率的图像。 未配置为检测数据的遗留应用程序可能不知道包含在混合图像文件中的更高分辨率图像,并且因此输出相对低分辨率的图像。

    • A method and system for applying an appropriate object ownership model is provided. In a preferred embodiment, an operating system selectively applies an object ownership model with which running programs are compatible. This permits programs designed to be used with operating systems that do not apply a rigorous object ownership model to be used with an operating system capable of applying a rigorous object ownership model. The method and system has both an automatic object deallocation phase and an object access control phase. In the automatic deallocation control phase, the method and system defers the automatic deallocation of objects owned by programs that are incompatible with automatic object deallocation until a later time at which no such programs are still running. Instead of immediately deallocating the objects owned by a terminating program, the method and system designates them for deferred deallocation. At a later time, the method and system checks to see whether any programs that are incompatible with automatic object deallocation are still running, and, if none are, the method and system deallocates all objects designated for deferred deallocation. In the object access control phase, the method and system allows special permissive access to objects owned by programs that are unable to authorize access to the object by other programs. Instead of denying access by a requesting program to an object owned by a program that is unable to authorize access to the object by other programs because it has not authorized any other programs to access the object, the method and system allows the requesting program to access the object.
    • 提供了一种应用适当对象所有权模型的方法和系统。 在优选实施例中,操作系统选择性地应用运行程序与之兼容的对象所有权模型。 这允许被设计为与不适用严格的对象所有权模型的操作系统一起使用的程序与能够应用严格的对象所有权模型的操作系统一起使用。 该方法和系统具有自动对象解除分配阶段和对象访问控制阶段。 在自动释放控制阶段,该方法和系统将自动释放与自动对象释放不兼容的程序所拥有的对象的自动释放,直到稍后的时间不再运行。 方法和系统不是立即释放终止程序所拥有的对象,而是将其指定为延迟释放。 在稍后的时间里,方法和系统会检查是否有任何与自动对象解除分配不兼容的程序仍在运行,如果没有,方法和系统将释放指定用于延迟释放的所有对象。 在对象访问控制阶段,方法和系统允许对由无法授权其他程序访问对象的程序所拥有的对象进行特殊的许可访问。 由于没有授权任何其他程序访问该对象,所以方法和系统允许请求程序访问由程序所拥有的对象,该程序无法授权其他程序访问对象,而不允许请求程序访问 物体。
