12.9.7 Images in ODT export

Embedding images

You can embed images within the exported document by providing a link to the desired image file with no link description. For example, to embed ‘img.png’ do either of the following:

[[file:img.png]]

[[./img.png]]

Embedding clickable images

You can create clickable images by providing a link whose description is a link to an image file. For example, to embed a image org-mode-unicorn.png which when clicked jumps to http://Orgmode.org website, do the following

[[http://orgmode.org][./org-mode-unicorn.png]]

Sizing and scaling of embedded images

You can control the size and scale of the embedded images using the #+ATTR_ODT attribute.

The exporter specifies the desired size of the image in the final document in units of centimeters. In order to scale the embedded images, the exporter queries for pixel dimensions of the images using one of a) ImageMagick’s identify program or b) Emacs create-image and image-size APIs¹⁵⁴. The pixel dimensions are subsequently converted in to units of centimeters using org-odt-pixels-per-inch. The default value of this variable is set to display-pixels-per-inch. You can tweak this variable to achieve the best results.

The examples below illustrate the various possibilities.

Explicitly size the image

To embed img.png as a 10 cm x 10 cm image, do the following:

#+ATTR_ODT: :width 10 :height 10
[[./img.png]]

Scale the image

To embed img.png at half its size, do the following:

#+ATTR_ODT: :scale 0.5
[[./img.png]]

Scale the image to a specific width

To embed img.png with a width of 10 cm while retaining the original height:width ratio, do the following:

#+ATTR_ODT: :width 10
[[./img.png]]

Scale the image to a specific height

To embed img.png with a height of 10 cm while retaining the original height:width ratio, do the following

#+ATTR_ODT: :height 10
[[./img.png]]

Anchoring of images

You can control the manner in which an image is anchored by setting the :anchor property of it’s #+ATTR_ODT line. You can specify one of the following three values for the :anchor property: ‘"as-char"’, ‘"paragraph"’ and ‘"page"’.

To create an image that is anchored to a page, do the following:

#+ATTR_ODT: :anchor "page"
[[./img.png]]
