How Can I Resize image in GraphNode

I’m using imagelist in GraphNode.
but my node’s image’size is vary small. so I’d like to resize image.
but there isn’t AutoResizes property in GraphNode. so i can’t.
Dose this case depend on the imagelist’s icon’s size?

If you have small images (bitmaps) in your ImageList, you will naturally have small GoImages.
However, you can change their size at any time, and GoImage will stretch/compress the image correspondingly. Just set GraphNode.Icon.Size.
