Team,

I copied two drawings, one from The Ruby Way 2nd edition and one from the
RMagick website.
I try to run the pgms but I get nothing. I mean nothing, no errors, I just
get the cursor back.

The first sample (The Ruby Way 2nd edition), and which I named
*magia01.rb*follows:

I run this pgm by typing: *ruby magia01.rb*. This is under MS Windows XP.

require 'RMagick'

img = Magick::ImageList.new
img.new_image(500, 500)

purplish = "#ff55ff"
yuck     = "#5fff62"
bleah    = "#3333ff"

line = Magick::Draw.new
50.step(450, 50) do |n|
    line.line(n,50,  n,450)
    line.draw(img)
    line.line(50,n,  450,n)
    line.draw(img)
  end

# Draw circle
cir = Magick::Draw.new
cir.fill(purplish)
cir.stroke('black').stroke_width(1)
cir.circle(250,200,  250,310)
cir.draw(img)

#Draw rectangle
rect = Magick::Draw.new
rect.stroke('black').stroke_width(1)
rect.fill(yuck)
rect.rectangle(340,380,  237,110)
rect.draw(img)

#Draw triangle
tri = Magick::Draw.new
tri.stroke('black').stroke_width(1)
tri.fill(bleah)
tri.polygon(90,320,160,370,390,120)
tri.draw(img)

img = img.quantize(256,Magick::GRAYColorspace)

img.write("drawing.gif")



Any help will be appreciated.

Thank you

Victor
