    摘要： A computer graphics system includes display logic (92) comprising a destination bit map (11) containing a plurality of image bits which map to a plurality of pixels for presenting an image, an auxiliary bit map (1) containing a plurality of area boundary bits representing pixels defining an area boundary line which encloses an area of the image, area filling logic (7) for operating upon those image bits enclosed by the area boundary line in order to fill the area with a particular pattern and color, characterized in that the display logic further comprises area boundary drawing logic (5) having line segmentation means to resolve the specified boundary line into a plurality of intersecting two pixel line segments which can, from that time forward, be operated upon separately to define the area boundary bits in accordance with conventional area boundary drawing rules.

    摘要： In a line generator and a method for determining the individual pixels to be plotted for a line to be drawn in a display system, coded representations of a plurality of lines are stored in a line definition table. The coded representation of each individual line is a string of data items representing the transitions between adjacent pixels to be plotted for drawing the individual line. Preferably, only coded representations of lines up to a predetermined size (i.e. the length of the line in the case of a straight line) are stored in the line definition table. Strings of data items for representing the pixels to be plotted for longer lines to be drawn are still calculated as in the prior art. In this case, control logic determines whether there are coded representations of a line to be drawn in the line definition table, or not, and passes control to appropriate processing logic for determining the pixels to be plotted. In a preferred embodiment, the string of data items forming the coded representation of a line to be drawn is a string of binary digits and the value of each bit in the string represents a transition in one of two directions. This provides a very compact representation of the line.

    摘要： It is known to obtain from a sinterable powder (e.g., of silicon nitride+metallic oxide sintering aid) a shaped article with at least 95% theoretical density, by the hot isostatic pressing of a preshaped body of the powder while that body is encapsulated in a gas-impermeable capsule which is plastic at the temperature of the hot gas by which the isostatic pressure is applied. Until now, a pressure of the order of 100 MPa has been treated as the practical minimum necessary for hot isostatic pressing. By the invention, a pressure less than 20 MPa is used, in conjunction with a degassing of the preshaped body, carried out prior to encapsulation, as in a vacuum whose pressure is no more than a few mm of mercury, and preferably less than 1 mm (approximately equal to 0.15 kPa).

    摘要： An apparatus and a method provide a solution for a computer system. The apparatus may include a package containing or referencing a plurality of software components of the solution and containing a solution definition defining in logical terms the topology requirements of the solution. The plurality of software components may be packaged as installable units which comprise a descriptor providing requirements of a target hosting environment for the software component and the software component to be installed. The solution definition of the package may include target hosting environments of the software components of a solution being defined in terms of requirements each software component has on its own target hosting environment and requirements the solution imposes on the target hosting environments.

    摘要： Stored data for two different images superimposed on one another can be accessed simply and efficiently from the same VRAM. The SAM of the VRAM is divided into multiple-independent portions, each of which respond to its own independently controlled address counter. By loading the image data access into respective SAM portions, and switching data access between SAM portions at the SAM address rate, superimposed data of two different images can be displayed from the same VRAM.
