How do I combine a number of images into a single PDF using ruby?

pdf, pdf-generation, rmagick, ruby

Solution

You can use RMagick's `ImageList#write`:

If the image format indicated by the filename supports multiple images per file (animated images), write writes all the images in the imagelist to a single file.

Example:

require 'rmagick'

image_list = Magick::ImageList.new("image1.png", "image2.png", "image3.png")
image_list.write("images.pdf")

Problem

I have an array of images. How can I combine them into a PDF, with one image per page? I've taken a look at RGhost and RMagic and the answer might be in there somewhere but it's eluding me right now.
