Various embodiments provide an ability to load documents and access page content associated with documents while the documents are still being loaded. In at least some embodiments, while a document's structure is being processed in the background, individual pages can be requested. The same can be said for individual documents that comprise a part of a package that contains multiple documents. In at least some embodiments, multiple threads are utilized to enable a document's structure to be built and to enable a user to access portions of the document while the document is being built or loaded.

Progressive page loading

Subject matter described herein is directed to providing font-rendering information (e.g., XPS file) that is usable to print a document. For example, a font file is received that defines a font type included in the document. A determination is made that a quantity of pages of the document does not exceed a subsetting-optimization threshold. When the quantity of pages does not exceed the threshold, a subsetted font file of the font type is generated. The subsetted file is provided, such as via the spool file, to a print subsystem.

Optimized font subsetting for a print path

Technology described herein is directed to converting display-rendering instructions (e.g., DIRECT2D) into print-rendering instructions (e.g., EMF, WMF, XPS, and SVG). For example, a request to print an item (e.g., document) is received, the item being displayable on an output device when display-rendering instructions are executed. A print render target is created that includes an instructions converter. The display-rendering instructions are routed to the print render target. The instructions converter maps the display-rendering instructions to the print-rendering instructions, which are usable to print the item.

Printing DIRECT2D-rendered items

Various technologies described herein pertain to filling a fill area of a canvas with a source visual object and/or a supplemental visual object to emulate a result of clamping the source visual object onto the fill area of the canvas. A source sub-region of a canvas is filled with the source visual object. Moreover, an extension sub-region of the canvas, which includes at least a part of the fill area outside the source sub-region, is formed based on the source sub-region of the canvas. Further, a supplemental visual object is generated by using a tiling clip on the source visual object and repeated within the extension sub-region of the canvas. The tiling clip specifies a size of the portion of the source visual object used as the supplemental visual object.

Clamp mode emulation

Various embodiments can be used to process packages or documents that contain markup language describing one or more documents. Markup language descriptions can be processed to identify certain objects that reoccur or are repeated in the markup language description. If a re-occurring or repeating object is encountered in the markup language description, a resource dictionary can be used to catalog such objects and, an associated object model can include, from the resource dictionary, references to a re-occurring or repeating object. By using the resource dictionary as such, memory resources can be conserved when an in-memory representation of the object model is built.

Load-time memory optimization

Systems, methods, and/or techniques ('tools') for determining Unicode points from glyph elements are provided. The tools may receive indications of commands that relate to text containing glyphs. Responding to the commands, the tools may convert the glyphs to corresponding Unicode representations. The tools may also provide glyph substitution tables that include Unicode fields for storing Unicode representations of characters, along with first and second glyph fields for storing glyphs of the characters. The glyph substitution tables may include links pointing from the second glyph fields to the first glyph fields, and may also include links pointing from the first glyph fields to the Unicode fields. The tools may provide character mapping tables that include Unicode fields for storing Unicode representations of characters. The character mapping tables may also include glyph fields for storing glyphs of the characters, and may include links pointing from the glyph fields to the Unicode fields.

Determination of unicode points from glyph elements

Semantic objects are created that provide a structure for markup language representations of documents. The semantic objects include text runs that are produced from the markup language representation and that are placed into semantic blocks that group text runs according to how text is logically structured in the document being represented. The text runs of each semantic block are ordered to correspond to the logical order of the document being represented. The semantic blocks corresponding to each page of the document being represented are ordered to correspond to the logical order of the document being represented. The ordered semantic blocks including the ordered text runs are saved as a semantic object which can they be utilized to make use of the logical structure of the document being represented by the markup language.

Creation of semantic objects for providing logical structure to markup language representations of documents

Various technologies and techniques detect lists in vector graphics based documents and use them in meaningful ways. The system detects at least one list in a vector graphics based document using a set of rules. Pattern detection logic identifies characters, symbols, numbers, letters, and/or images that may start a list. Additional pattern detection logic determines if a list exists. The system can identify and parse bulleted lists, numbered or lettered lists, and nested lists that are any combination of both. Once identified, the content is translated into a modified format. The content can be output to a destination application in the modified format that is more suitable for output or use by the destination application.

Finally, the tools may provide character mapping tables that include Unicode fields for storing Unicode representations of characters. The character mapping tables may also include glyph fields for storing glyphs of the characters, and may include links pointing from the glyph fields to the Unicode fields.

Techniques relating to story tracking for fixed layout markup documents are described. In one instance, a process identifies stories contained in a fixed layout markup document. The process also determines which portions of the fixed layout markup document relate to an individual story.

Story tracking for fixed layout markup documents

Various technologies and techniques detect tables in vector graphics based documents and use them in meaningful ways. The system detects at least one table in a vector graphics based document using a set of rules. The rules include analyzing a set of content representing horizontal and vertical lines to find intersections and identifying table cells based on the intersections. Once identified, the table content is translated into a modified format. The content can be output to a destination application in the modified format that is more suitable for output or use by the destination application.

Analyzing lines to detect tables in documents

Techniques relating to structural context for fixed layout markup documents are described. In one instance, a process defines content and associated positional information of a document with a set of content markup. The process also specifies a structural configuration for the document relative to at least some of the content markup, such that the structural configuration is separate from the content markup.

Structural context for fixed layout markup documents

Systems, methods, and/or techniques ('tools') for improved search techniques for page-based document layouts are described herein. The tools may analyze markup elements defined for pages within source documents, and may determine whether the markup elements for the page may include at least part of a search string.
