Abstract

Generating a preview representative of a font is provided. A font typeface preview engine generates a preview font file comprising a plurality of font typeface preview elements, wherein each font typeface preview element is associated with a cloud-based font. The font typeface preview engine further generates 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. The preview font file and the mapping file are transmitted to a client application executing on a computing device for rendering the plurality of font typeface preview elements as representations of the fonts in a font selection menu. The size of the preview font file can be kept very low. Thus, the computing device is enabled to render the font typeface preview elements with high fidelity, while saving memory allocation for fonts and reducing processor load.

Claims

1. A computer-implemented method for generating a preview representative of a font comprising:

generating a preview font file at a font system, the preview font file comprising a plurality of font typeface preview elements, wherein each font typeface preview element is associated with a font;

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; and

transmitting 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 application does not include the fonts represented by the font typeface preview elements.

2. The computer-implemented method of claim 1, wherein generating the preview font file comprises:

loading a plurality of font files, each font file including a plurality of glyphs in a typeface of a font;

extracting a subset of glyphs from each font file;

for each subset of glyphs, generating a font typeface preview element, wherein the font typeface preview element is a representation of the font; and

packaging the font typeface preview elements in the preview font file.

3. The computer-implemented method of claim 2, wherein generating a font typeface preview element comprises combining the subset of glyphs into a single glyph.

4. The computer-implemented method of claim 2, wherein extracting the subset of glyphs from each font file comprises, for each font, extracting each glyph in a name of the font.

5. The computer-implemented method of claim 2, further comprising:

extracting character properties from each font file; and

for each subset of glyphs, generating the font typeface preview element according to the character properties.

6. The computer-implemented method of claim 5, wherein for each subset of glyphs, generating the font typeface preview element according to the character properties comprises at least one of:

spacing, shaping, positioning, and contextually reordering the glyphs in the subset of glyphs in accordance with the character properties.

7. The computer-implemented method of claim 1, further comprising providing the preview font file and the mapping file to a client application for rendering the plurality of font typeface preview elements as representations of the fonts in a font selection menu, wherein the client application does not include the fonts represented by the font typeface preview elements.

8. The computer-implemented method of claim 7, wherein providing the preview font file and the mapping file to a client application comprises transmitting the preview font file to the client application, wherein the client application is executing on a client computing device.

9. The computer-implemented method of claim 7, wherein providing the preview font file and the mapping file to a client application comprises providing the preview font file and the mapping file to the client application during build time.

10. The computer-implemented method of claim 7, further comprising:

receiving an indication of a selection of a font; and

transmitting a font file including a plurality of glyphs in a typeface of the selected font to the client application executing on a client computing device.

11. A system for generating a preview representative of a font, comprising:

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 operable to generate 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 wherein the font typeface preview engine comprises;

a mapping file generator operable to generate 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.

12. The system of claim 11, wherein the font typeface preview engine further comprises:

a font loader operable to load a plurality of font files, each font file including a plurality of glyphs in a typeface of a font type;

a glyph and property extractor operable to extract a subset of glyphs from each font file;

a preview font generator operable to generate a font typeface preview element for each subset of glyphs, wherein each font typeface preview element is a representation of a font type; and

a preview font package generator operable to package the font typeface preview elements in the preview font file.

13. The system of claim 12, wherein in generating a font typeface preview element, the preview font generator is operable to combine the subset of glyphs into a single glyph.

14. The system of claim 12, wherein in extracting the subset of glyphs from each font file, the glyph and property extractor is operable to, for each font type, extract each glyph in a name of the font type.

15. The system of claim 12, wherein the glyph and property extractor is further operable to extract character properties from each font file.

16. The system of claim 15, wherein, for each subset of glyphs, the preview font generator is further operable to generate the font typeface preview element according to the character properties.

17. The system of claim 15, wherein the font typeface preview engine further comprises a shaping engine operable to, for each subset of glyphs:

consult the character properties; and

space, shape, position, or contextually reorder the glyphs in the subset of glyphs in accordance with the character properties.

18. The system of claim 15, wherein the character properties include logic associated with at least one of:

spacing;

shaping;

positioning;

special behaviors; and

contextual reordering.

19. The system of claim 11, wherein the system further comprises:

an output engine operable to provide the preview font file and the mapping file to a client application for rendering the plurality of font typeface preview elements as representations of the fonts in a font selection menu, wherein the client application does not include the fonts represented by the font typeface preview elements; and

a font manager operable to;

receive an indication of a selection of a font; and

transmit a font file including a plurality of glyphs in a typeface of the font to the client application executing on a client computing device.

20. 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 a preview representative of a font, 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 wherein generating the preview font file comprises;
