Members

Functions

clear void clear(): Clear storage.
commands auto commands(): Returns forward range with all glyph commands.
flatten NVGPathOutline flatten(): Returns "flattened" path. Flattened path consists of only two commands kinds: MoveTo and LineTo.
flatten NVGPathOutline flatten(NVGMatrix mt): Returns "flattened" path, transformed by the given matrix. Flattened path consists of only two commands kinds: MoveTo and LineTo.

Properties

empty empty [@property getter]: Is this outline empty?
length int length [@property getter]: Returns number of commands in outline.

Static functions

createNewBezier NVGPathOutline createNewBezier(float x1, float y1, float x2, float y2, float x3, float y3, float x4, float y4): Create new path with cubic bezier (first command is MoveTo, second command is BezierTo).
createNewQuad NVGPathOutline createNewQuad(float x0, float y0, float cx, float cy, float x, float y): Create new path with quadratic bezier (first command is MoveTo, second command is QuadTo).
