RMagick

I have stumbled upon an odd bug, and it is confirmed on both my local [Windows] dev box and my remote shared host.

I have a tileset, for all intents and purposes it contains:
upper left, upper * n, upper right
west, middle * n, east
lower left, lower * n, lower right

This allows me to create grid (n+2)*(n+2)

I append them together as row1, row2, and row3
Then I make an ImageList of row1, 20 row2's, and row3
I go to do a vertical append (append(true) in Ruby) - and my CPU jumps to full load.

I let the task run for about 45 minutes before I decided that shit wasn't finishing.

If I put row1, 2, and 3 to disk, and append those vertically - it works just fine.

If I do this with far smaller numbers (row1 being 3 units wide, instead of 23) - it seems to work OK.

I'm stumped, /prog/ - does anyone have experience with ImageMagick that could explain this shit?

[Windows] dev box
near complete lack of context
description of what you think it should do rather than actual code
These are but three of your problems.

Next time use documented software

How is that a lack of context?


require 'rubygems'
require 'RMagick'
include Magick

row1 = ImageList.new("200nw.png")
row2 = ImageList.new("200w.png")
row3 = ImageList.new("200sw.png")

24.times do
  row1 << Image.read("200n.png")[0]
  row2 << Image.read("200a.png")[0]
  row3 << Image.read("200s.png")[0]
end

row1 << Image.read("200ne.png")[0]
row2 << Image.read("200e.png")[0]
row3 << Image.read("200se.png")[0]

row1 = row1.append(false)
row2 = row2.append(false)
row3 = row3.append(false)

row1.write("row1_test.png")
row2.write("row2_test.png")
row3.write("row3_test.png")

final = ImageList.new
final << row1
24.times do
  final << row2
end
final << row3

final = final.append(true)
final.write("superfinal.png")

Too bad Ruby is slow as fuck.
