Patent Application
20170091155
A cloud-based font delivery/streaming service enables applications to download fonts on demand, thereby reducing application package size and disk footprint. Typically, applications provide a font selection menu comprising a list of fonts available to the application from which a user can select a desired font. To provide hints to the user as to what the fonts look like prior to committing to a font, it is desirable for the application to render previews of the font names (or other representations of the fonts) in their own typefaces. When a font file of a given font is stored on the cloud (i.e., not locally), rendering a high fidelity preview of the font in its own typography can be difficult.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description section. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter. Aspects are directed to an automated system, method, and device for generating an independent preview font file for presenting font typeface preview elements representative of cloud-based fonts in a font selection menu.
In some examples, a font system includes one or more processors for executing programmed instructions, memory coupled to the one or more processors for storing program instruction steps for execution by the computer processor, a font typeface preview engine for: generating a preview font file, the preview font file comprising a plurality of font typeface preview elements, wherein each font typeface preview element is associated with a font; and generating a mapping file comprising location data mapping each font to a storage location of its associated font typeface preview element in the preview font file.
In some examples, a method for generating an independent preview font file for presenting font typeface preview elements representative of cloud-based fonts in a font selection menu includes: generating a preview font file, the preview font file comprising a plurality of font typeface preview elements, wherein each font typeface preview element is associated with a font; and generating a mapping file comprising location data mapping each font to a storage location of its associated font typeface preview element in the preview font file.
In some examples, one or more computer storage media storing computer-usable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform a method for: generating an independent preview font file for presenting font typeface preview elements representative of cloud-based fonts in a font selection menu, the method comprising: generating a preview font file, the preview font file comprising a plurality of font typeface preview elements, wherein each font typeface preview element is associated with a font; and generating a mapping file comprising location data mapping each font to a storage location of its associated font typeface preview element in the preview font file.
In some examples, the font system provides the preview font file and the mapping file to a client application executing on a client computing device for rendering the plurality of font typeface preview elements as representations of the fonts in a font selection menu, wherein the client computing device does not include the fonts. In some examples, the font system receives an indication of a selection of font, and transmits a font file including a plurality of glyphs in the typeface of the selected font to the client application executing on the client computing device.
By generating a plurality of font typeface preview elements, wherein each element is representative of an available cloud-based font and comprised of a subset of glyphs of the font, and packaging and providing the plurality of font typeface preview elements in a preview font file, the size of the preview font file can be kept very low. Thus, a computing device receiving the preview font file is enabled to render the plurality of font typeface preview elements in a font selection menu with high fidelity, while advantageously saving local memory allocation for fonts, minimizing the disk footprint, and reducing processor load. For example, the computing device is enabled to render the plurality of font typeface preview elements rather than downloading all of the available fonts to the client computing device or loading and rendering each glyph of each font name (or other representations of the fonts), which requires a lot of memory allocation and processing.
Rendering the plurality of font typeface preview elements in a font selection menu provides an intuitive user interface for users. For example, displaying representations of fonts that are not locally stored on a computing device in the fonts' own typefaces provides users with a high fidelity visual clue of the fonts and typefaces available, thus improving usability of the font selection menu.
Examples are implemented as a computer process, a computing system, or as an article of manufacture such as a computer program product or computer readable media. According to an aspect, the computer program product is a computer storage media readable by a computer system and encoding a computer program of instructions for executing a computer process.

In one example, the font database 106 is a single device at a single location, for example, on a single server. In another example, the font database 106 includes a plurality of storage devices that are distributed among different locations, for example, on a plurality of distributed servers. In some examples, the font typeface preview engine 110, the font manager 104, and the font database 106 are located on a single computing device or server. In other examples, the font typeface preview engine 110, the font manager 104, and the font database 106 are distributed across a network on multiple computing devices, servers, or data stores.
According to an aspect, for each font file 108, the font typeface preview engine 110 is operable to load the font file 108 from the font database 106, extract a subset of glyphs and character properties from the font file 108, and generate a single-glyph font typeface preview element 124a-n (collectively, 124) representative of the font. In some examples, the subset of glyphs includes the glyphs in the font's name and in the typeface of the font. For example, the preview font for the font “Arial” includes the glyphs “A,” “r,” “i,” “a,” and “I” combined into a single glyph in the Arial typeface. The font typeface preview engine 110 is further operable to package each generated font typeface preview element 124 into a preview font file 112, and generate a mapping table file 116 for mapping the name of each font to the storage location of the font typeface preview element 124 in the preview font file 112.
According to an aspect, the font system 102 is operable to provide the preview font file 112 comprising the generated font typeface preview elements 124 and the mapping file 116 to one or more applications 118 executing on a client computing device 114. In some examples, an application 118 executing on the client computing device 114 downloads the preview font file 112 from the font system 102. The font system 102 is operable to transport the preview font file 112 and the mapping file 116 to the client computing device 114 over a distributed computing network 120, such as the Internet or an intranet. In other examples, the font system 102 provides the preview font file 112 for packaging with a client application 118 at build time of the client application 118.
Although illustrated as a tablet computing device in

According to examples, the glyph and property extractor 210 is illustrative of a software module, system, or device operable to determine a subset of glyphs to extract from each font file 108, and to extract the subsets of glyphs. In some examples, the glyph and property extractor 210 extracts the glyphs that comprise the name of the font. For example and with reference to
Referring back to
According to one aspect, the preview font generator 212 is in communication with a shaping engine 220. According to another aspect, the preview font generator 212 includes a shaping engine 220. The shaping engine 220 is operable to consult the character properties extracted by the glyph and property extractor 210, and space, shape, position, and contextually reorder the glyphs 304 in the subset of glyphs 302 in accordance with the character properties. For example, the character properties include logic associated with spacing, shaping, positioning, special behaviors, or contextual reordering. In some examples, the character properties further include logic associated with language-specific properties. The preview font generator 212, in conjunction with the shaping engine 220, generates a plurality of single-glyph font typeface preview elements 124 that are accurate representations of the fonts in the font files 108 stored in the font database 106.
With reference again to
According to examples, the mapping file generator 216 is illustrative of a software module, system, or device operable to generate a mapping file 116 that maps each font to the location of its associated font typeface preview element 124 in the preview font file 112. For example, the mapping file 116 is a mapping table.
According to examples, the output engine 218 is illustrative of a software module, system, or device operable to provide the preview font file 112 comprising the generated font typeface preview elements 124 and the mapping file 116 to one or more client applications 118. In some examples, the output engine 218 is operable to transmit the preview font file 112 to a client application 118 executing on a client computing device 114 over a distributed computing network 120, such as the Internet or an intranet. Accordingly, the client computing device 114 is operable to receive the preview font file 112 and the mapping file 116 (e.g., download the preview font file 112 and mapping file 116), and store the preview font file 112 and the mapping file 116 in a local data repository 122 such that the font typeface preview elements 124 and the mapping file 116 are available for use by the one or more applications 118 executing on the client computing device 114.
In other examples, the output engine 218 is operable to provide the preview font file 112 and the mapping file 116 for packaging the preview font file 112 and the mapping file 116 with a client application 118 at build time.
For example and with reference to
With reference now to
After the font typeface preview engine 110 generates a plurality of font typeface preview elements 124, packages the plurality of font typeface preview elements 124 in a preview font file 112, and generates a mapping file 116 including location data 402 that maps each of the font to the locations of the font typeface preview elements 124 in the preview font file 112, the font typeface preview engine 110 outputs the preview font file 112 and the mapping file 116 to a client application 118 executing on a client computing device 114. The client computing device 114 then stores the preview font file 112 and the mapping file 116 in a data repository 122 associated with the client computing device 114.
When an indication of a selection to view a listing of fonts available to a client application 118 is received, the client application 118 reads the location data 402 in the mapping file 116 for the locations of the font typeface preview elements 124 for the fonts available to the client application 118. The client application 118 then retrieves the font typeface preview elements 124 from the preview font file 112 for displaying the font typeface preview elements 124 in a font selection menu 126.
When an indication of a selection of a font typeface preview element 124 in the font selection menu 126 is received, the client application 118 sends a request 404 to the font manager 104 for the font file 108 associated with the font represented by the selected font typeface preview element 124. For example, if the user selects font typeface preview element 124c, which is representative of the Algerian font, the client application 118 sends a request 404 to the font manager 104 for the font file 108c for the Algerian font. The font manager 104 retrieves the font file 108c residing in the font database 106, and transports the font file 108c to the client application 118.
Having described an operating environment, a data flow example, and various aspects with respect to
The method 500 continues to an extraction operation 515, where the glyph and property extractor 210 determines which glyphs 304 to extract from the font files 108, and extracts the determined subsets of glyphs 302 and character properties from each font file 108. According to an aspect, the determination of which glyphs 304 to extract from a font file 108 is made according to the representation of the font that is desired. For example, if the name of a font is the desired representation of the font, the glyph and property extractor 210 extracts the glyphs 304 that comprise the name of the font (e.g., the “A,” “r,” “i,” “a,” and “I” glyphs 304a-e are extracted from the Arial font file 108). According to another aspect, the determination of which glyphs 304 to extract from a font file 108 is made according to a particular language or location. For example, for a particular region or language, certain fonts may be available. Additionally, it may be desired for the fonts to be represented in a particular language using glyphs 304 of the particular language (e.g., Japanese characters).
The method 500 continues to a preview element generation operation 520, where, for each subset of glyphs 302, the preview font generator 212 combines the glyphs 304 into a single-glyph font typeface preview element 124. According to an example, the preview font generator 212 employs a shaping engine 220 to consult the character properties associated with spacing, shaping, positioning, special behaviors, or contextual reordering, and space, shape, position, or reorder the glyphs 304 in the subset of glyphs 302, or apply special behavior to the glyphs 304 in the subset of glyphs 302 in accordance with the character properties.
The method 500 continues to a packaging operation 525, where the preview font package generator 214 collects the plurality of font typeface preview elements 124 generated by the preview font generator 212, and packages the plurality of font typeface preview elements 124 into a preview font file 112.
The method 500 continues to a mapping file generation operation 530, where the mapping file generator 216 generates a mapping file 116 that maps each font of the plurality of font files 108 to the location of its associated font typeface preview element 124 in the preview font file 112.
The method 500 continues to a transmission operation 535, where the output engine 218 provides the preview font file 112 to a client application 118. In some examples, the output engine 218 transmits the preview font file 112 and the mapping file 116 to a client application 118 executing on a client computing device 114 over a distributed computing network 120 in response to receiving a request for the client application 118 to download the preview font file 112 and the mapping file 116. In other examples, the output engine 218 provides the preview font file 112 and the mapping file 116 to a font manager 104 for packaging the preview font file 112 and the mapping file 116 with a client application 118 at build time. Accordingly, a client application 118 executing on the client computing device 114 is enabled to access the plurality of font typeface preview elements 124 in the preview font file 112 for displaying font typeface preview elements 124 in a font selection menu 126.
For example, the client application 118 reads the mapping file 116 for finding the storage locations of the font typeface preview elements 124 associated with the fonts that are available to the client application 118, pulls the associated font typeface preview elements 124 from the preview font file 112, and renders the font typeface preview elements 124 in the font selection menu 126. Accordingly, the fonts are represented in their own typographies. A user of the client application 118 is enabled to see an accurate representation of the available fonts.
The method 500 ends at OPERATION 540.
The method 545 begins at start operation 550 and proceeds to a selection operation 555, where an indication of a selection of a font is received. According to examples, the indication of the selection of the font is in response to a selection made by a user of a font typeface preview element 124 in a font selection menu 126, wherein the font typeface preview element 124 is associated with the font. According to examples, the indication of the selection is communicated to the font manager 104 via a client application 118 executing on a client computing device 114.
The method 545 continues to a transmission operation 560, where the font file 108 including the glyphs 304 and character properties of the selected font are transmitted to the client application 118 executing on the client computing device 114. Accordingly, the client application 118 is enabled to utilize the selected font for rendering glyphs and characters in the typeface of the font.
The method 545 ends at OPERATION 565.
