	I have created custom node having image and text below it, referring custom node sample provided with the download. Scenario is in some case text might be there, minimal text and very large text, so, I want my node to shrink expand based on the amount of text. resize to fit etc. options are not working for me. Please provide some help on this. Thanks in advance.

	There's undocumented diagram.measureString: function (text, font, bounds, styled) you could call to measure the text and resize the node based on returned size. E.g. ShapeNode's resizetoFitText uses it like this: Code ... var rc = this.bounds.clone(); var size = this.parent.measureString(text, font, rc); rc.height = size.height; this.setBounds(rc, true, true); ... You might also want to add some margins to the rectangle or enforce minimum width for the image. I hope that helps, Stoyan
