The conversion of a document of a first format that supports a set of raster operations into a document of a second format that does not support one or more unhandled raster operations of the set of raster operations is disclosed. For example, one disclosed embodiment comprises locating a region in the document of the first format that contains an unhandled raster operation, rasterizing the region in the document of the first format that contains the unhandled raster operation to form a rasterized region, and incorporating the rasterized region into the document of the second format.

Handling unhandled raster operations in a document conversion

Techniques are provided for performing font subsetting. One or more font subsetting parameters are received. The one or more font subsetting parameters indicate a granularity level for which font subsetting is performed for portions of a data container. The font subsetting parameters indicate a font subsetting granularity level other than an entire document associated with the data container. A first portion of the data container is determined in accordance with the font subsetting granularity level. A subset of font data for at least one font family is determined in accordance with what font data for the at least one font family is actually used by the first portion. The subset of font data is embedded in an output for a consumer.

Techniques for granular font subsetting for efficient document consumption

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.

In one embodiment, methods and architectures are provided that heuristically analyze an incoming vector path data stream over multiple DDI calls, and merge the path data strips into a single gradient element. This single gradient element can then be processed, as by being serialized into XAML, so that it can be somewhat more efficiently consumed by a consuming device. Merging of the vector path data can eliminate or at least reduce noticeable seams, conserve parsing time and reduce memory consumption.

Vector path merging into gradient elements

In one embodiment, image data that corresponds to a single image, received through multiple DDI calls, is analyzed and merged or otherwise combined into a single image element. This single image element can then be processed, as by being serialized into XAML, so that it can be somewhat more efficiently consumed by a consuming device. Merging of the image data can eliminate or at least reduce noticeable seams, conserve parsing time and reduce memory consumption.
