Rendering source content for display

Abstract

A method for rendering source content for display in a destination figure is provided. The method may include receiving the source content of the file, replicating the source content in a region surrounding the source content, such that replicated source content is aligned with the source content, extracting an axis-aligned rectangular tile containing the source content from the region, and rendering the axis-aligned rectangular tile onto the destination figure.

1 . A method for rendering source content for display in a destination figure comprising:
 receiving source content in a file;   identifying multiple drawing operations in the file to print the source content;   upon identifying the drawing operations, selecting one or more predefined rendering calls for a specified rendering engine, wherein at least some of the predefined rendering calls are selected to include a plurality of the drawing operations; and   rendering the source content to the destination figure utilizing the selected predefined rendering calls via the specified rendering engine.

         8 . The method of  claim 7 , wherein the fixed document file is a XML Paper Specification (XPS) file. 
     
     
         9 . The method of  claim 8 , wherein the rendering engine is a graphics device interface (GDI) rendering engine of an XPS rendering system. 
     
     
         10 . The method of  claim 9 , wherein receiving, identifying, and selecting are performed by a XPS-to-GDI conversion module of the XPS rendering system. 
     
     
         11 . A computing system comprising:
 a processing subsystem; and   a data storage device holding instructions that when executed by the processing subsystem:   receive source content in a file;   identify multiple drawing operations in the file to print the source content;   upon identifying the drawing operations, select one or more predefined rendering calls for a specified rendering engine, wherein at least some of the predefined rendering calls are selected to include a plurality of the drawing operations; and   render the source content to a destination figure utilizing the selected predefined rendering calls via the specified rendering engine.   
     
     
         12 . The computing system of  claim 11 , wherein the drawing operations include associated rendering primitives.

         14 . The computing system of  claim 11 , wherein identifying the drawing operations includes identifying all of the drawing operations to print the source content; and
 wherein selecting is performed upon identifying all of the drawing operations, and the predefined rendering calls are selected to include a plurality of the drawing operations when possible.   
     
     
         15 . The computing system of  claim 11 , wherein the predefined rendering calls include geometric figures or collections of geometric figures.

         17 . The computing system of  claim 11 , wherein the file is a fixed document file. 
     
     
         18 . The computing system of  claim 17 , wherein the fixed document file is a XML Paper Specification (XPS) file, and wherein the rendering engine is a graphics device interface (GDI) rendering engine of an XPS rendering system. 
     
     
         19 . A method for rendering source content for display in a destination figure comprising:
 receiving source content in a file;   identifying multiple drawing operations to print the source content;   upon identifying a number of drawing operations greater than a threshold number, selecting one or more predefined rendering calls for a specified rendering engine, wherein at least some of the predefined rendering calls are selected to include a plurality of the drawing operations, and wherein the threshold number of drawing operations is sufficiently large enough to enable selection of the predefined rendering calls; and   rendering the source content to the destination figure utilizing the selected predefined rendering calls via the specified rendering engine.   
     
     
         20 . The method of  claim 19 , wherein the threshold number of drawing operations is the total number of drawing operations for printing the source content.
