<path>

<path> (path) defines any line passing through two or more points within a surface element. [11.1 Digital Facsimiles 11.2.2 Embedded Transcription]
Module transcr — Representation of Primary Sources
Attributes
points⚓︎ identifies a line within the container or bounding box specified by the parent element by means of a series of two or more pairs of numbers, each of which gives the x,y coordinates of a point on the line.
Derived from att.coordinated
Status Optional
Datatype 2–∞ occurrences of teidata.point separated by whitespace
Member of
model.linePart
Contained by
transcr: line surface zone
May contain Empty element
Note

Although the simplest form of a path is a straight line between two points, a line with more than two points may bend at any point. The order of coordinates in points is significant, because the line follows the coordinate sequence.

To specify a closed polygon, use the zone element rather than the path element.
Example
<surface ulx="0" uly="0" lrx="443" lry="272">
 <graphic url="facs-fig3.jpg"/>
 <path points="74,73 171,244"/>
 <path points="71,203 173,116"/>
</surface>
Schematron Since a path> represents a line with distinct start and end points, the last coordinate should not be the same as the first coordinate.
