摘要： A method and apparatus are provided for embedding a font subset in an electronic document. The method in one form includes analyzing a document having characters of a font set where characters may have different forms depending on the location of the character in a word or one or more ligatures represent a combination of characters. A font subset is created corresponding to only the character forms present in the document and the font subset is associated with the document. Advantageously, the embedded font subset only contains the font characters which are used in the document and not all characters which may be present in a complete font set for all font sets referenced in the document.

摘要： Provided is a method for font data streaming for time-based video/audio presentations where content is transmitted in small increments and transmission continues while a previously transmitted portion is viewed or played. Different subsets of characters of the same font are assembled together on a device and previously sent characters are reused for rendering subsequent text strings. Font subsets are created to provide only a minimal number of glyphs for the character set coverage, thereby reducing the redundancy of font data transmission and reducing the total number of characters transmitted.

摘要： A method for enhancing a digital image for printing or display on a high resolution device is described. The method includes receiving a digital source image and selecting a block of source pixels from the image. An edge array is generated from edges detected in the block of source pixels and processed with a set of logic operations to detect one of a set of edge patterns. The source coordinate system is transformed into a second coordinate system in response to the detected edge pattern and a transformed source location for the output pixel is determined. A modified transformed source location is determined by applying a modifier function. The modifier function is selected from a set of functions in response to the detected edge pattern. An effective source location is generated by applying a reverse transformation. The value of the output pixel is interpolated from the values of the block of source pixels based on the effective source location.

摘要： At least two different pixel clock frequencies or pixel pitches are used when generating an image. They are used with periodic halftone patterns in a color scanning printing process. By using different clock frequencies for the different color separations, more options for screen geometry are available, and therefore new screen sets with desirable moiré behavior are possible. This is especially important on low resolution devices, such as 1200 dpi and below. Here there are a limited number of rational tangent screen geometries that are available and moiré canceling or moiré averting combinations are scarce. The different pixel clock frequency are used when writing at least two color channels in order to provide otherwise unavailable halftone geometries.
摘要翻译：当生成图像时，至少使用两个不同的像素时钟频率或像素间距。它们与彩色扫描打印过程中的定期半色调图案一起使用。通过为不同的色彩分色使用不同的时钟频率，可以使用更多的屏幕几何选项，因此可以使用具有令人满意的莫尔行为的新屏幕。这对于低分辨率设备尤其重要，如1200 dpi及以下。这里有一些有限数量的合理切线几何可用，并且波纹消除或莫尔条纹组合很少。在写入至少两个颜色通道时使用不同的像素时钟频率，以提供否则不可用的半色调几何。

摘要： A method of recovering a pixel clock for generating a digital image from an analog video signal is presented. The on and off-transition times for the active video portion of a digital image and the image size defined in a video standard are used to generate a pixel clock. The analog video signal is digitized according to the pixel clock and the image size of the resulting digital image is compared with the image size defined in the video standard. The pixel clock frequency is adjusted in response to the image size comparison. The optimum phase of the pixel clock relative to the analog video signal is determined through a repetitive phase adjustment technique. A first image coordinate is determined for a pixel clock at one phase and a subsequent image coordinate is determined for a pixel clock after decrementing the phase of the pixel clock. The first image coordinate and the subsequent image are compared. If the coordinates are not equal, the steps of decrementing the phase of the pixel clock and determining a corresponding image coordinate are repeated until equal coordinates are determined. The phase of the pixel clock is then adjusted by a predetermined value to yield an optimum phase.
摘要翻译：提出了从模拟视频信号中恢复生成数字图像的像素时钟的方法。使用数字图像的活动视频部分的开和关转换时间以及视频标准中定义的图像大小来生成像素时钟。根据像素时钟将模拟视频信号数字化，并将所得数字图像的图像大小与视频标准中定义的图像大小进行比较。响应于图像尺寸比较来调整像素时钟频率。通过重复相位调整技术确定像素时钟相对于模拟视频信号的最佳相位。对于一个相位的像素时钟确定第一图像坐标，并且在递减像素时钟的相位之后为像素时钟确定后续图像坐标。比较第一图像坐标和后续图像。如果坐标不相等，则重复降低像素时钟的相位并确定对应的图像坐标的步骤，直到确定相等的坐标。然后将像素时钟的相位调整预定值以产生最佳相位。
