I often do diagrams in PowerPoint, attach the ppt/pptx to the page, and use the "Office Powerpoint" macro to in-line individual slides into my wiki page. The ability to control the size of the in-lined ppt slide is important to me, and as far as I can tell, the options to set height and width are independent of each other, and I don't see a way to set just the height or just the width, and have the other dimension automatically scale proportionally. So, I often end up with a distorted image, or having to take the extra steps to manually calculate the correct "other value."

I'm hoping you could have a checkbox to say "scale proportionally" or maybe even have an unspecified dimension automatically behave that way if the other dimension is constrained. Or maybe just do something like for your "Image" widget that just has a single "Resize image to specific width" field that does proportional scaling.

Also, I wasn't sure whether this issue should have been tracked under the Office Connector (OFFCONN) JIRA project instead.
