title: List of diagram / image editors for Delphi
body: <p>I need a good diagram / image editor for a Delphi application. I need the ability to place an image in the editor, and use freely positioned balloons / tips to describe parts of the image. The result must be exported as an image. </p>
  
  <p>So far, I have evaluated <a href="http://www.ksdev.com/blockengine/index.html" rel="nofollow noreferrer">KSDev Block Engine</a> and <a href="http://www.tmssoftware.com/site/diagram.asp" rel="nofollow noreferrer">TMS Diagram studio</a> but am not completely satisfied with both of them. The former seems to have lots of little quirks and bugs and both of them don't seem to be able to export their content as an image (PNG with alpha channels is required).</p>
  
  <p>Are there any other editors you know of that I might evaluate ?</p>
