^"A path represents the outline of a shape which can be filled or stroked. A path can also be used as a clipping path, to describe animation, or position text." W3C 2018 より引用。
^ ab"A path is made up of multiple segments, and every command, either explicit or implicit, other than moveto or closepath, defines one path segment." W3C 2018 より引用。
^"A path is defined by including a ‘path’ element on which the d property specifies the path data." W3C 2018 より引用。
^"The 'moveto' commands (M or m) must establish a new initial point and a new current point." W3C 2018 より引用。
^"L (absolute) l (relative) lineto Draw a line from the current point to the given (x,y) coordinate which becomes the new current point." W3C 2018 より引用。
^"H (absolute) h (relative) horizontal lineto Draws a horizontal line from the current point." W3C 2018 より引用。
^"V (absolute) v (relative) vertical lineto Draws a vertical line from the current point." W3C 2018 より引用。
^"The 'closepath' (Z or z) ends the current subpath by connecting it back to its initial point. An automatic straight line is drawn from the current point to the initial point of the current subpath." W3C 2018 より引用。
^"curveto ... Draws a cubic Bézier curve from the current point" W3C 2018 より引用。
^"smooth curveto ... Draws a cubic Bézier curve from the current point ... The first control point is assumed to be the reflection of the second control point on the previous command relative to the current point." W3C 2018 より引用。
^"quadratic Bézier curveto ... Draws a quadratic Bézier curve from the current point" W3C 2018 より引用。
^"smooth quadratic Bézier curveto ... Draws a quadratic Bézier curve from the current point ... The control point is assumed to be the reflection of the control point on the previous command relative to the current point" W3C 2018 より引用。
^"A (absolute) a (relative) elliptical arc Draws an elliptical arc from the current point" W3C 2018 より引用。
^"The syntax of path data is concise in order to allow for minimal file size and efficient downloads, since many SVG files will be dominated by their path data. Some of the ways that SVG attempts to minimize the size of path data are as follows:" W3C 2018 より引用。
^"basic shape ... A graphics element that is defined by some combination of straight lines and curves. Specifically: ‘circle’, ‘ellipse’, ‘line’, ‘path’, ‘polygon’, ‘polyline’ and ‘rect’." W3C 2018 より引用。
^"The ‘line’ element defines a line segment that starts at one point and ends at another." W3C 2018 より引用。
^"The ‘polyline’ element defines a set of connected straight line segments." W3C 2018 より引用。
^"For rounded rectangles, the computed values of the rx and ry properties define the x- and y-axis radii of elliptical arcs used to round off the corners of the rectangle." W3C 2018 より引用。
^"The ‘polygon’ element defines a closed shape consisting of a set of connected straight line segments." W3C 2018 より引用。
^"Mathematically, these shape elements are equivalent to a ‘path’ element that would construct the same shape." W3C 2018 より引用。
^"The shape-rendering property provides a hint to the implementation about what tradeoffs to make as it renders vector graphics elements" W3C 2018 より引用。
^"optimizeSpeed ... emphasize rendering speed ... will sometimes cause the user agent to turn off shape anti-aliasing." W3C 2018 より引用。
^"crispEdges ... emphasize the contrast between clean edges of artwork ... might turn off anti-aliasing for all lines and curves or possibly just for straight lines which are close to vertical or horizontal. Also, the user agent might adjust line positions and line widths to align edges with device pixels." W3C 2018 より引用。
^"emphasize geometric precision over speed and crisp edges." W3C 2018 より引用。
