Path builders shared by the public API and the chart renderers.
These append path ops only — the caller decides whether to fill,
stroke, or fill_stroke the result.
Summary
Functions
Appends a closed polygon path through points (a list of {x, y}).
Fewer than two points draws nothing.
Appends a rounded-rectangle path. radius is clamped to half the
shorter side, so an over-large radius degrades to a stadium instead
of turning inside out. A radius of 0 emits a plain rectangle.
Functions
@spec polygon(PrawnEx.Document.t(), [{number(), number()}]) :: PrawnEx.Document.t()
Appends a closed polygon path through points (a list of {x, y}).
Fewer than two points draws nothing.
Useful for the small marks a document needs but a single-byte font
cannot spell — arrows, carets, tick marks — since those glyphs have
no WinAnsi codepoint and would otherwise transliterate to ?.
@spec rounded_rect( PrawnEx.Document.t(), number(), number(), number(), number(), number() ) :: PrawnEx.Document.t()
Appends a rounded-rectangle path. radius is clamped to half the
shorter side, so an over-large radius degrades to a stadium instead
of turning inside out. A radius of 0 emits a plain rectangle.
