Abstract

Glyph aware snapping is described. A content processing system receives a selection input to select a glyph from text content presented via a user interface of a content editing application. Responsive to this, the content processing system generates and presents snapping guidelines in relation to the glyph while preserving an ability of the glyph to be editable using text editing tools. These snapping guidelines correspond to an identified subset of linear segments of the glyph and enable the content processing system to snap a focus (e.g., a cursor) of a graphics editing tool from a position proximate the snapping guidelines to a position on the snapping guidelines. This enables the content processing system to generate graphical content that aligns with the snapping guidelines and can be attached to the glyph based on the alignment—without destroying the ability of the text content to be editable using text editing tools.

Claims

1. In a digital medium environment to aid graphical design in relation to text content included as part of digital visual content, a method implemented by at least one computing device, the method comprising:

receiving, by the at least one computing device, user input via a graphics editing tool for editing digital visual content that includes text content, the user input indicating an alignment of graphical content with a guideline presented in relation to a glyph included as part of the text content;

generating, by the at least one computing device, updated digital visual content by aligning the graphical content with the glyph via the guideline independent of converting the glyph to an outline; and

presenting, by the at least one computing device and via a user interface, the updated digital visual content, each glyph of the text content as included in the updated visual content being editable using a text editing tool.

2. A method as described in claim 1, further comprising:

receiving a selection input selecting the glyph from the text content;

presenting at least a first snapping guideline in relation to the glyph;

snapping a focus of the graphics editing tool to a first position in the user interface that corresponds to the first snapping guideline, the snapping based on the user input positioning the focus proximate the first snapping guideline; and

aligning the graphical content to the glyph based, in part, on the first position.

3. A method as described in claim 2, wherein the selection input comprises hovering the focus proximate the glyph.

4. A method as described in claim 2, wherein the selection input is received in relation to a user interface instrumentality indicative of an option to present snapping guides for the glyph.

5. A method as described in claim 2, further comprising:

presenting a second snapping guideline in relation to the glyph;

snapping the focus of the graphics editing tool to a second position in the user interface that corresponds to the second snapping guideline, the snapping to the second position based on the user input repositioning the focus proximate the second snapping guideline after the focus is snapped to the first position; and

aligning the graphical content to the glyph further based on the second position.

6. A method as described in claim 1, further comprising receiving text editing input via the text editing tool to edit the text content as included in the updated digital visual content.

7. A method as described in claim 6, wherein the text editing input indicates to edit at least one of:

a font of the text content;

characters included in the text content, the text editing input indicating to add or remove one or more of the characters in relation to a caret;

or

a paragraph characteristic associated with the text content.

8. A method as described in claim 1, wherein generating the updated visual content comprises:

retrieving outline information for the glyph from a font data store, independent of converting the glyph to an outline; and

transforming the outline information into a line list table that describes an angle, and intercept, and a length of each of a plurality of linear segments for the glyph.

9. A system comprising:

at least one processor; and

a computer-readable storage medium having instructions stored thereon that are executable by the at least one processor to perform operations comprising;

receiving a selection of a glyph included in text content that comprises a plurality of glyphs;

generating information describing a subset of linear segments that combine to form a shape of the selected glyph;

generating snapping guidelines in relation to the selected glyph, the snapping guidelines enabling modification of the selected glyph by extending the shape of the selected glyph outside a bounding box of the selected glyph; and

modifying the shape of the selected glyph, independent of converting the selected glyph to an outline, responsive to receiving input at one or more of the snapping guidelines, the plurality of glyphs remaining editable using a text editing tool after modifying the shape of the selected glyph.

10. A system as described in claim 9, the operations further comprising generating graphical content having an alignment that corresponds to at least one of the snapping guidelines, wherein modifying the selected glyph comprises adding the graphical content to the subset of linear segments.

11. A system as described in claim 9, the operations further comprising generating the snapping guidelines for horizontal and vertical linear segments of the subset.

12. A system as described in claim 9, the operations further comprising generating the snapping guidelines for non-horizontal and non-vertical linear segments of the subset.

13. A system as described in claim 9, the operations further comprising generating the snapping guidelines substantially equidistant between pairs of horizontal and pairs of vertical linear segments of the subset.

14. In a digital medium environment to aid graphical design in relation to text content included as part of digital visual content, a method implemented by at least one computing device, the method comprising:

receiving, by the at least one computing device and via a user interface, a selection input to select a glyph included as part of text content;

retrieving, by the at least one computing device, outline information describing a shape of the glyph from font data maintained for the text content;

transforming, by the at least one computing device, the outline information into a list of segment entries describing linear segments that form the shape of the glyph;

generating, by the at least one computing device, snapping guidelines based on the linear segments;

receiving, by the at least one computing device, input to one or more of the snapping guidelines that alters the shape of the glyph; and

modifying the shape of the glyph in response to receiving the input, independent of converting the glyph to an outline, and preserving an ability to edit the modified shape of the glyph together with at least one other glyph of the text content using a text editing tool.

15. A method as described in claim 14, wherein the outline information describes the shape of the glyph using Bezier curves and the Bezier curves are transformed into the list of segment entries.

16. A method as described in claim 14, wherein a segment entry describes at least one of an angle, intercept, or length of a respective linear segment.

17. A method as described in claim 14, wherein the outline information specifies at least one of:

correspondence of a linear segment with a bounding box of the glyph;

or

a length of a linear segment.

18. A method as described in claim 14, wherein the retrieving the outline information describing the shape of the glyph is performed independent of converting the glyph to an outline.

19. A method as described in claim 14, further comprising receiving a request to change a font attribute of the text content and changing the font attribute of the glyph and the at least one other glyph responsive to receiving the request.

20. A method as described in claim 14, further comprising receiving text editing input via the text editing tool editing the text content including the modified shape of the glyph.
