How do I see a sample RMagick drawing? Help, Please!

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

The programs don't display the image, they just create it. All you have to do is open the file "drawing.gif" with any image viewing program. Use Internet Explorer, for example, or Paint.

Tim,

That worked fine.

One thing, I can't see the colors. The image appears to be in black and
white (it goes from light dark to very dark).
I played with the colors but I never see any color.

Again, thank you for your help

That's because you're using the GRAYColorspace. You need to use something else.

... and, to compound my problem, this is the very first time I play with
RMagick.
It is actually very nice! I hope to learn it well.

Thanks again,
