Abstract: Digital image editing techniques are described as implemented by a depth-aware system of a computing device. The depth-aware system employs a depth-aware grid that defines constraints for depth-aware editing of digital images involving perspective. These techniques support automated editing in which changes to directional spacing, perspective arrangement, perspective movement, object redistribution, and so on are implemented in real time, which is not possible in conventional techniques involving object distortion. As such, these techniques improve operation of the computing device that implements these techniques as well as user efficiency in interacting with the computing device to perform digital image editing that involves perspective.

Abstract: In implementations of application-based font previewing, a font preview system of a computing device receives a font file corresponding to a font of a font repository via a network. The font preview system encrypts font tables of the font file and the font preview system writes the encrypted font tables to a font disk cache of the computing device. The font preview system writes metadata describing the font tables to a font memory cache of the computing device. In response to receiving a request to preview the font from an application of the computing device, the font preview system uses the metadata to identify and decrypt a particular font table of the encrypted font tables, and the application renders glyphs of the font in a user interface using the decrypted particular font table.

Abstract: In implementations of glyph weight modification, a glyph modification system represents an outline of an unmodified glyph as segments having start points and endpoints. The segments have directions based on the start points and the endpoints such that an endpoint of a segment is a start point of another segment. The system identifies features of the unmodified glyph based on the segment directions. A property of the unmodified glyph can be modified by changing coordinates of points of the segments based on the identified features. The glyph modification system generates a modified glyph having the modified property using the points of the segments with the changed coordinates.

Abstract: Systems, methods, and non-transitory computer-readable media are disclosed for determining a glyph and a font from a vector outline by applying various combinations of hash-based querying, path-descriptor matching, or anchor-point matching. For example, the disclosed systems can select a subset of candidate glyphs for a vector outline based on (i) comparing hash keys of candidate glyphs with a point-order-agnostic hash key corresponding to the vector outline and (ii) comparing a path descriptor for a primary path of the vector outline to path descriptors corresponding to candidate glyphs. By further comparing anchor points between the vector outline and the subset of candidate glyphs, the disclosed systems can select both a glyph and a font matching the vector outline.

Abstract: Techniques described herein take character glyphs as input and generate a text-on-a-path text object that includes the character glyphs arranged in a determined order along a path. For instance, a method described herein includes accessing character glyphs in input data. The method further includes determining an order for the character glyphs based on relative positions and orientations of the character glyphs in the input data. The method further includes generating a path for the character glyphs, based on the order, and associating the path with the character glyphs. Further, the method includes generating a text object that includes the set of character glyphs arranged in the order along the path.

Abstract: Digital image object anchor point techniques are described that increase user efficiency in interacting with a user interface to create digital images. This is achieved through use of anchor points by the digital image editing system that are defined with respect to an actual geometry of the object. Further, filtering and prioritization techniques are also leveraged to promote real world utility and efficiency of these techniques as a balance between having too many and two few anchor points.

Abstract: In implementations of systems for simultaneously modifying multiple variable fonts, a computing device implements a modification system to identify a first range of values of a glyph attribute that are adjustable by changing values of a particular design axis of a first variable font that is common to the first variable font and a second variable font. The modification system identifies a second range of values of the glyph attribute that are adjustable by changing values of the particular design axis of the second variable font. An overlapping range of values of the glyph attribute is determined between the first range of values and the second range of values. The modification system generates an additional instance of the first variable font and an additional instance of the second variable font for display in a user interface based on the overlapping range of values of the glyph attribute.

Abstract: Methods, systems, and non-transitory computer readable storage media are disclosed for selectively modifying live digital vector glyphs. For example, the disclosed system can use a vector description of a live vector glyph having a plurality of regions defined by a plurality of paths to determine a vector document object model including style information for the paths. The disclosed system can extract a color for a selected region from the style information for the paths (e.g., from a stylesheet) and then change the extracted color to a selected color. After modifying the color, the disclosed system can then generate an updated vector description with the modified region color and render the updated live vector glyph at a client device. The disclosed system thus updates the live vector glyph while maintaining the glyph as a live glyph.

Abstract: In implementations of systems for generating instances of variable fonts, a computing device implements a similarity system to receive input data describing attribute values of glyphs of an input font. The similarity system generates a custom instance of a variable font by modifying a value of a registered design axis of the variable font based on the attribute values. A similarity score is determined that describes a visual similarity between the custom instance of the variable font and the input font. The similarity system identifies an additional design axis of the variable font based on the similarity score and generates an instance of the variable font that is visually similar to the input font by modifying a value of the additional design axis.

Abstract: An object is coupled to a glyph in a text segment, while maintaining the text segment as editable. The text segment includes glyphs, which are graphical representations of characters. Each glyph is defined internally in the form of path information, which includes one or more points corresponding to the outline of the glyph. The path information for the text segment is determined and utilized in order to facilitate the coupling of an object with the text segment. The text segment remains editable as text subsequent to such coupling.
