The present disclosure includes, among other things, systems, methods and program products for pre-computing image manipulations.

Pre-computing image manipulations

A computer-implemented graphics program that correctly adapts images being printed to the physical capabilities of a printer. A published virtual paper is scaled to a physical paper, taking into account the virtual paper's size, geometry bounds for an image from the virtual paper being printed, balanced geometry bounds calculated from the geometry bounds, the physical paper's size and a printable area of the physical paper, so that the image being printed fits within a printable area of the physical paper.

Using geometry bounds to enable scale printing of virtual paper onto physical paper when using a printer with a differing printable area

A computer implemented system, method, and article of manufacture provide access to a drawing. A server computer has one or more server component applications. One or more drawing files are created by a first drawing application and stored on the server computer. A search server component application executes on the server computer and provides a query engine that allows queries of the one or more drawing files to locate data. A conversion server component application executes on the server computer and dynamically convert the drawing files into a drawing file format viewable by a client application executing on a client compute. The server component applications are further configured to provide the one or more drawing files that have been dynamically converted to the client computer.

Method and apparatus for providing access to drawing information

A method, apparatus, and article of manufacture for automating the finding and serving of CAD design data is disclosed. One or more embodiments of the invention increase the level of access and automation possible with design data. One or more embodiments of the invention provide a server comprised of various components including an information extraction component, a search component, and a conversion component. The various components provide users with enhanced access to drawing and design data. One or more embodiments of the invention also provide programmable, scriptable components that can query, filter, manipulate, merge, and translate design drawing data using the Web browser interface. Further, Web site administrators can use the present invention to dynamically index and publish design drawing data.

The present invention discloses an apparatus, method, and article of manufacture for generating graphic images. In accordance with the present invention, an application program receives commands from a computer user via an input device and provides an output command stream to a plurality of renderer programs. The renderer programs selectively modify the output command stream and transmit the output command stream to a graphics peripheral device or to one or more of the other renderer programs.

Immediate mode drawing interface for the construction of graphics

The present invention discloses a method, apparatus, and article of manufacture for compressing vector data. The vector data is normalized to create normalized vector data. A history buffer is searched for a longest matching vector data that matches the normalized vector data. The longest matching vector data is encoded by assigning a substitution code. The vector data is normalized by translating the vector data to an origin and scaling the vector data to a unit square. The substitution code includes a denormalization function, which converts the normalized vector data to vector data.
