PNG Supported?

I am trying to use a .png for the background image of my chart and I get an error "Unknown picture file extension (.png)" I see that graphs can be exported as .png files. It sure seems like you should be able to use them as backgrounds. Am I missing something?
Thanks.

Hi,
this features is not yet available (allow to use .png for the background). I've added on our wish list to be considered for further releases.

Hi,
some comments on this :
To have PNG, you can download whatever PNG library. There are so big, and we cannot include them into the TeeChart installation. You can see some of them at :

Hi,
Can you elaborate a little bit on what you are saying? My application already supports PNG. I am using GDI+ for all of my graphics drawing. The TChart interface however only allows me to pass in a file name to set the back ground image of the IPanel. Are you saying I should be able to draw the PNG in the chart myself or that I could do a conversion into a supported format or what? Thanks for any more information you can provide.
