[cairo-commit] rcairo/tests ps,NONE,1.1

[Evan Martin]

Committed by: martine

Update of /cvs/cairo/rcairo/tests
In directory pdx:/tmp/cvs-serv21675/tests

Added Files:
	ps 
Log Message:
Update cairo.h parser to properly handle structs with exposed members, which
recently appeared in Cairo CVS.
(Unfortunately, this means I'll have to write my own getters/setters for each
member.  I think I'll wait for the API to settle.)

Add a "ps" test that generates a simple postscript file (mostly to verify my
understanding of the mapping from C's FILE* to Ruby's File objects).



--- NEW FILE: ps ---
#!/usr/bin/env ruby
# vim: set ts=2 sw=2 et :

$LOAD_PATH << "../src"
require 'cairo'

cr = Cairo::Cairo.new

# tweak these:
SIZE = 4
DPI = 200
FILENAME = 'ps.ps'

# derived constants:
PIXELS = SIZE * DPI
MARGIN = PIXELS/40

File.open(FILENAME, "w") { |f|
  cr.set_target_ps(f, SIZE, SIZE, DPI, DPI)
  cr.set_rgb_color(0,0,0)
  cr.line_cap = Cairo::LineCap::ROUND
  cr.line_width = PIXELS/40
  cr.stroke {
    cr.move_to(MARGIN, MARGIN)
    cr.line_to(PIXELS-MARGIN, PIXELS-MARGIN)
  }
  cr.show_page
}
puts "wrote #{SIZE}x#{SIZE}in, #{DPI}dpi image to #{FILENAME}."
