Subject: RMagick -- TIF to PDF

This works:

require 'RMagick'
img_array = Magick::Image.read('C:/test.tif')
imgs = Magick::ImageList.new
for image in img_array
  image = image.negate
  image.compression= Magick::LZWCompression
  imgs<<image
end

imgs.write('C:/testImg1.pdf')

but it seems like the long way around the barn. Anyone care to suggest
improvements?

Especially:

image = image.negate.

 If that isn't in there, the PDF comes out the negative of the TIF,
but it seems like it ought to be unnecessary. Is it a bug, or did I do
something silly?
