org-odt.el: Support for anchoring an image to a page
* etc/styles/OrgOdtStyles.xml(OrgPageImage) (OrgPageImageCaptionFrame): New styles for anchoring an image centrally on a page. * lisp/org-odt.el (org-odt-entity-frame-styles): Accommodate new frame styles: \"OrgPageImage\" and \"OrgPageImageCaptionFrame\". (org-export-odt-format-image): Handle frame-related :anchor, :style and :attributes options attached to images as shown below: [[./image.png]] (org-odt-merge-frame-params): New. Auxiliary routine to merge the default frame params and user-specified frame params. (org-odt-format-entity): Use the above `org-odt-merge-frame-params'. Jérémy Compostella <jeremy.compostella@gmail.com> writes: I need to add pictures that are anchored to the \"page\" and not to the \"paragraph\". This is very useful to get a \"floating picture\" on an entire page without text breaks. He also adds: Sometimes, you want to add a picture but you don't want a page break. For example, you want to add a big illustration. To render correctly, the picture needs its own page but you don't want to break the page. In this case you need to anchor the picture to the \"page\". http://lists.gnu.org/archive/html/emacs-orgmode/2011-11/msg00869.html
