US 2017/0249286 A1 · Acquisition of a Font Portion Using a Compression Mechanism

Abstract

Acquisition of a font portion using a compression mechanism is described. In certain embodiments, an end-user device determines multiple characters to be displayed but are missing from a local font. The end-user device computes a compressed representation of the multiple characters based on multiple code points corresponding to the multiple characters. The end-user device transmits a font request including the compressed representation to a font repository. The font request may be implemented as a uniform resource locator (URL). The font repository, such as a server, decodes the compressed representation to identify at least the multiple code points encoded by the end-user device. The font repository prepares a font description including glyph data corresponding to the multiple code points and returns the font description. The end-user device produces a local font that includes at least multiple glyphs corresponding to the multiple requested characters. The local font production may include font augmentation.

Dependent claims

At least one computing device operative in a digital medium environment to enable acquisition of a font portion that is specified in real-time using a compression mechanism that facilitates lossless identification of enumerated characters, the computing device configured to perform operations comprising:

determining multiple characters that comprise a portion of a font definition;
ascertaining multiple code points that respectively correspond to the multiple characters;
computing a compressed representation of at least the multiple characters based on the multiple code points;
communicating to a font repository a font request including the compressed representation;
receiving from the font repository a font description that corresponds to the compressed representation;
and
producing a local font that includes multiple glyphs that correspond to the multiple characters using the font description, the local font comprising a version of the font definition.
