widthheight.md

Edit save_images.rb with

def capture_page_image(browser, url, width, file_name)
  width, height = width.split('x')
  puts `"#{browser}" #{@config['phantomjs_options']} "#{snap_file}" "#{url}" "#{width}" "#{file_name}" "#{height}"`
end

Edit snap.js with

var view_port_height = system.args[4];
page.viewportSize = { width: view_port_width, height: view_port_height};

Edit config with

screen_widths:

• 1280x1024

You're right, and that could be done in the snap.js file without modifying Wraith at all... okay, I will use that for now, thanks!

So I went with doing the split in the snap.js file. One side-effect of that hack is that the gallery images are marked with and ordered by the "size" which ignores the 'x' part of the argument

so images with the same width are treated as being part of the same set of snaps and only one of the diff images in that set will be displayed. Can be worked around by making sure no two widths are the same, e.g.
