Overview

XML Parser parses XML documents containing dynamic images. You can give many images into one XML document.

XML document has to be in same hierarchy as in pure ruby. Save, save_endless and treir quality option is given as dynamic_images’s attribute.

Save_endless images limit is gives as attribute too. It’s name is :save_endless_limit.

Save_endless filename has to be given as string attribute. You can set place of index by %{index}. F.e.: "image-%{index}.png".

Options are taken from element attributes. There is same rules like in pure ruby. See DynamicImage.
