Systems and methods are presented that process documents, identify fonts being used to reproduce the documents, and identify conflicts based on the identified fonts. The systems and methods may identify a font associated with a document, identify a conflict between the font and another font, determine a substitute font for the document, and then modify information of the substitute font and the document based on the conflict to prevent the identified conflict from causing the document to be incorrectly processed. The systems and methods may then allow the document to be further processed based on the modified information.

Accurate font activation

Documents that are created using a particular font often do not include all glyphs defined for the font. Accordingly, to reduce the amount of bandwidth needed to obtain the font used to create the document over a network, a font file may be created that includes a reduced set of glyphs. In one or more examples, the font file might only include the glyphs used in the document being viewed. Reduced glyph font files may be generated on-the-fly and/or cached for quick retrieval at a later time.

Reduced glyph font files

To resolve compatibility issues between font file formats and user agents such as web browsers, a font repository may determine a compatible font file format upon receiving a request from the user agent for a font. The determination may be made based on the type of user agent making the request. In one or more arrangements, if a font file in the compatible font file format is not available at the repository, a request may be transmitted to another repository. A font reference in a style sheet or code defining the network document may be unique to the font, but common to all font files corresponding to the font. An application for facilitating the generation of a network document may thus automatically generate such a code in response to a user selecting a desired font.

Serving font files in varying formats based on user agent type

Fonts may be activated based on the applications that are launched or operating on a computing device. Accordingly, if an application needs a particular set of fonts, the fonts may be activated upon launching of that application. Fonts may further be deactivated when they are no longer necessary or needed by the application (e.g., when the application is terminated). If supported by an operating system, instead of activating and deactivating the fonts, fonts may be pre-activated and then hidden from the operating system. The pre-activated fonts may be revealed when needed for the applications and then hidden again when the applications terminate.

Activation of fonts using font sets

Methods, computer readable media, and apparatuses for preventing unauthorized font linking are presented. A request for a font file may be received. It may be determined whether the request is valid, and this determination may be based on a security token and/or a referrer string. If the request is determined to be valid, a first watermark may be embedded in the font file, and the first watermark may be based on the security token. The first watermark may include at least one point in at least one glyph contained in the font file. A second watermark may be embedded in the font file, and the second watermark may include at least one table that identifies a customer. The font file then may be served to the requestor.

Preventing unauthorized font linking

Text may be contextually previewed in various fonts using preview panes with a level of transparency. Fonts or font groups may then be applied to a document using the preview panes. In one example, text to be inserted may be previewed in different fonts against the document in which the text is to be added. Once a user has selected a desirable font, the user may choose to insert the text into the document using the preview pane. Alternatively, a user may apply a font to existing text from the preview pane. Text in fonts of different types and/or sizes may be previewed in a variety of formats in a single preview area and/or with individual font preview panes.

Contextually previewing fonts

A system, method and computer program product are provided for communicating over a network without a direct connection to the network. A process is first initiated on a first computer without a direct connection to a network. In response to the process, a second computer coupled to the first computer with a direct connection to the network is automatically identified. Data is then communicated between the first computer and a server computer over the network via the direct connection of the second computer.

Network connection-independent updating system and method

A method, system, and computer program product reports malware events in real-time and does not cause network congestion that adversely affects the usability of the network. A method of reporting malware events comprises the steps of detecting a malware event, determining a level of the detected malware event, comparing the level of the detected malware event to an event trigger threshold, and transmitting a notification of the detected malware event, based on the comparison of the level of the detected malware event to the event trigger threshold.
