Abstract: Using LIDAR technology, terabytes of data are generated which form massive point clouds. Such rich data is a blessing for signal processing and analysis but also is a blight, making computation, transmission, and storage prohibitive. The disclosed subject matter includes a technique to convert a point cloud into a form that is susceptible to wavelet transformation permitting compression that is nearly lossless.

Abstract: 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.

Abstract: A method, system, and architecture for a font service and a software development kit (SDK) to provide developers with the means to design user-interfaces and content using a wide variety of font typefaces. The SDK may download a font from a font service as needed and activate the font to be rendered in the software application's user interface or other textual content within the application. A subscription service may be provided which comprises user account information or other data relating to permissions for one or more client devices to access one or more font files located in a font library. Further, one or more font files may be optimized according to an operating system in which the target application is operating and/or a screen resolution of a client device on which the target application is operating.

Abstract: 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.

Abstract: Methods, computer readable media, and apparatuses for enabling non-system fonts are presented. A listing of a plurality of non-system fonts may be provided within an application. Responsive to a selection of one of the plurality of non-system fonts by a user of the application, the one of the plurality of non-system fonts may be enabled within the application.

Abstract: 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.

Abstract: Methods, computer readable media, and apparatuses for font matching are presented. A glyph may be received and processed. The processing of the received glyph may include reducing the glyph, computing bounds associated with the glyph, and normalizing the glyph. The processed glyph may be compared to a repository of image prototypes. The comparison may include determining a distance of the processed glyph from one or more the image prototypes, sorting the determined distances, and selecting one or more of the image prototypes based on the determined distances. Additional techniques may be used to enhance the resolution or accuracy associated with the various methods and algorithms.

Abstract: 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.

Abstract: 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.

Abstract: Using LIDAR technology, terabytes of data are generated which form massive point clouds. Such rich data is a blessing for signal processing and analysis but is also a blight, making computation, transmission, and storage prohibitive. The disclosed subject matter includes a technique to convert a point cloud into a triangular network permitting users to query spatial distance between points at different levels while facilitating compression that is nearly lossless.

Abstract: Systems and methods for activating and/or managing fonts allow users to selectively activate individual fonts from inside a multi-font suitcase by separating the individual fonts from a multi-font suitcase file. The separated font may then be saved in a font management “vault” or file that activates only the fonts desired and selected by the user. In this manner, individual fonts can be activated from a font suitcase file without requiring that the entire suitcase's set of fonts be activated and/or added to the font management vault. Users may designate and select different fonts, including different fonts from different foundries (and included in different multi-font suitcases) for a single electronic document (e.g., different fonts for different typeface types, etc.) or use in an application program. These features provide repeatability and predictability in electronic document rendering processes.

Abstract: A method of generating a sequence of matrix factors for a transformation matrix having a plurality of rows and columns using a computer, wherein the transformation matrix stores data values representing a wavelet transform. In a first aspect, at least one plurality of row reduction operations are applied to the transformation matrix. The sequence of matrix factors is generated from the reduced transformation matrix and the row reduction operations. A scaling factor may be removed from the transformation matrix before applying the row reduction operations, wherein the scaled transformation matrix has a determinant with a coefficient equal to 1 or ?1. In yet another aspect, the transformation matrix may have a nonzero monomial determinant and the sequence of matrix factors further includes a scaling matrix. The method may include further alternative features described herein.

Abstract: Method and system aspects are described for ensuring accurate font matching in exchanged documents. The aspects include forming a database of font specifications. The aspects further include accessing the database when saving and opening documents to ensure usage of proper fonts.
