ReadonlycanvasDeliberately undefined: a primitive that wants an offscreen canvas asks the context for its element, and the honest answer is that there is none.
ReadonlyheightWhere along the dash list a stroke starts, as a canvas reads it.
ReadonlyunsupportedNames of the calls that could not be exported, first occurrence only.
ReadonlywidthAn <img> becomes an <image> of its src; a canvas becomes one of its
data URL. The nine-argument crop is a nested <svg> whose viewBox is the
source rectangle. Anything else (an ImageBitmap, a video frame) has no
URL to point at and is skipped.
Open an explicit <g> with the given attributes, optionally translated
and clipped to a rectangle in the group's own coordinates. The chart wraps
each pane in one so the export carries the same per-pane offset and clip
the DOM stacking gives the canvases. Balanced by popGroup.
The radii argument takes the forms the paint code uses: one number, or an array of up to four (top-left, top-right, bottom-right, bottom-left, the CSS order). Radii are scaled down together when they would overlap, as the canvas does, so a pill shorter than its radius stays a pill.
A 2D context that writes SVG. Construct one at the document's media size, hand it (cast) to whatever paints, and read
toString().
