Shapes library for Prawn

Available thus far:

  • star
  • half_star
  • arc
  • pie_slice
  • half_circle
  • quarter_circle

Usage

Install the prawn_shapes gem, then:

require 'prawn_shapes'

And:

pdf.star([x, y], :radius => r)

pdf.arc_around([x, y], :radius => r, :start_angle => 30, :end_angle => 60)
pdf.pie_slice([x, y], :radius => r, :start_angle => 45, :end_angle => 135)
pdf.half_circle([x, y], :radius => r, :side => :left)
pdf.quarter_circle([x, y], :radius => r, :quadrant => 3)

The built in prawn magic works:

pdf.stroke_star([x, y], :radius => r)
pdf.fill_star([x, y], :radius => r)
pdf.fill_and_stroke_star([x, y], :radius => r)

See the examples directory for further usage examples.

arcs and pies
