摘要： An extended colorspace which has a higher accuracy and a wider gamut than sRGB color space is disclosed. The extended color space includes an alpha channel which defines the translucency of the color image. The alpha channel is different from known alpha channels in that the inventive alpha channel can represent “super transparent” and “super opaque” values by allowing the alpha parameter (α) to be greater than 1 and less than 0. A data structure for storing the extended colorspace information has three fields, a sign field, an integer field and a decimal field. The sign field defines whether an integer is negative or positive. The integer field defines the integer, wherein the integer defines the super or under saturated values for color and alpha components. The decimal field defines the fine detailed information for the value of the color and alpha components.

摘要： The present invention provides a method, apparatus and computer-readable medium for providing high quality substantially visually error-free conversion of color images. The method maps the color values to an expanded colorspace to represent substantially all colors without perceptible visual error and labels an image determined by the mapped color values as an expanded colorspace image. Thus, the present invention may be utilized to provide a linear color management system. In a 16 bit color data value system, transparency/opaqueness information may be stored, and premultiplied or premultiplied and normalized values may be used for blending.

摘要： A system and method for processing color objects provides optimal processing quality by supporting both a perceptual-based color space and a physical-based color space and utilizing both color spaces for color processing in an integrated manner transparent to the end user. The graphics engine of the system includes a module for converting a color object being processed between the perceptual-base color space and the physical-based color space. During color processing that may involve various perceptual-based and physical-based operations, the graphics engine automatically converts the color object from one of the perceptual-based and physical-based color spaces to the other depending on the color processing operation to be performed. The graphics engine may also perform conversions on input graphic data from an input device to one of the dual color spaces for processing and converting a processed class object into the color space of an output device for displaying or printing.

摘要： A system and method of providing a transformable region that may be used on graphics devices having different resolutions. The original path and geometric data of the region, as well as all operations performed on the data, are preserved when generating the region. The device-independent region can be described by a hierarchical tree, wherein the leaf nodes contain path or rectangle, ellipse, pie, and polygon data and the branch nodes contain the operations to be performed on the regions. As the tree is traversed and regions are used, they are converted to a device resolution-specific from such that the operations are performed on device resolution-specific regions. Matrix transformation operations (e.g., translate, scale, skew and rotate) can be applied because the original path information is preserved and if the region is to be used in a device having a different resolution or a subsequent matrix operation is to be applied to the region, the tree can be re-traversed.

摘要： The present invention provides a method and apparatus for rendering images on a computer screen. Under the invention, a portion of a base image is described using a path. The path is then transformed using a non-affine transform to produce a transformed path. The transformed path is then rendered onto the computer screen. Another aspect of the present invention is a method and apparatus for rendering curves of any order and any dimension. In particular, the present invention provides a means for converting a function of any order and any dimension that describes one segment of a curve into a function that describes a different sized segment or an adjoining segment.

摘要： An image storage and processing method constructs, clips, fills, and combines arbitrary 2-dimensional shapes in an advanced graphics system. The method supports processing of anti-aliased images by compressing the image into a novel AlphaRegion data structure. AlphaRegion encodes into the data structure both the partially transparent as well as the fully opaque alpha values of an image according to rectangular bands. A band is a contiguous series of scan lines that have the same pattern of alpha values in a single direction. AlphaRegion encoding results in a more compact representation than possible in a conventional bitmap, but without losing the anti-aliasing features. AlphaRegion can be constructed either by supersampling sub-scan lines of an image, from the scan lines of a gray-scale image, from an existing conventional 1-bit Region or alpha mask buffer, or directly from a scan-line conversion of a geometric shape. AlphaRegion stores image data into three arrays, yInfo, xInfo and alphaData. Methods provided with AlphaRegion include rendering methods for filling or clipping the area on the drawing surface and methods for combining two AlphaRegions using boolean combination operators OR, AND, XOR, SUBTRACT, or SUBTRACT_FROM.

摘要： An image passthrough extension structure and method facilitating the transfer of compressed data image files from a software application to a device via the computer system operating system. The application determines whether the device is capable of decoding the specific compressed data file by polling the device driver. If the driver returns a “no support” message, the application processes the compressed data file in a conventional manner. If the driver returns a “support” message, the application transfers the compressed data file, along with the additional processing information, to the device driver utilizing the conventional file transfer operating system data structures modified to incorporate the compressed data file passthrough function. By allowing an application to transfer a compressed image file directly to a device driver, the present invention improves image fidelity and improves overall computer system efficiency by reducing the size of data files transferred between the application, the operating system and the hardware device.
摘要翻译： 图像直通扩展结构和方法，便于通过计算机系统操作系统将压缩数据图像文件从软件应用传输到设备。 该应用程序通过轮询设备驱动程序来确定设备是否能够解码特定的压缩数据文件。 如果驱动程序返回“不支持”消息，则应用程序以常规方式处理压缩数据文件。 如果驱动程序返回“支持”消息，则应用程序将压缩数据文件连同附加的处理信息一起传送到设备驱动程序，利用修改为包含压缩数据文件直通功能的常规文件传输操作系统数据结构。 通过允许应用将压缩图像文件直接传送到设备驱动器，本发明通过减小应用程序，操作系统和硬件设备之间传输的数据文件的大小来提高图像保真度并提高整体计算机系统效率。
