Transparent background in Visio 2013

I'm using Visio 2013 and I'm not able so save my drawings with a transparent background (background always ends up with white color)

The sheet background is "no background".

When I click "save as .PNG" (or .gif) there opens up a options menue. There I can also choose a background color but there are just colors and no "transparent" options.

Thanks in advance!

In your PNG options simply tick Transparancy Color:

Don't amend the colour, leave both as they are, and save.

In this example Drawing1 was saved with this option ticked, and Drawing 2 without:

To preserve partially transparent content:

1. Export as a .SVG file
2. (optional) In the the exported file, increase the "width" and "height" attributes. This will increase the render resolution in step 4
3. Open the .SVG in internet explorer. Microsoft's extensions break SVG in other apps.
4. Right click the displayed image and save it as a .png
