I was wondering if it's possible to use a png in a view. I'd like to use it as background to draw lines on it.

Thanks!

If you look at the example Tool called:

Kyma:Xtra Tools:widget sampler.pci

you'll see how to create a GraphicContext and save it in a variable called graph.  Then you can use an expression of the form:

(KymaLook readPNG: 'hilbertTransform.png') displayOn: graph.

to display the image in a .png file on that graphics context.

I have added this as an example in the 'widget sampler.pci' found in the Xtra Tools folder of the Kyma folder.  Look in the InitialState, the TriggeredResponse called (ListSelection == 'Blue Pill').
