Is there anyway to set the amount of transparency on a shape?
https://developer.mozilla.org/en-US/docs/CSS/color_value describes how you can specify CSS color values that have transparency in them.
So you can see examples of this in GoJS where a Shape.fill or Shape.stroke or TextBlock.stroke or GraphObject.background is set to something like: fill: “rgba(128,128,128,0.2)”
More globally you can set the Panel.opacity or Layer.opacity properties. These numbers between 0 and 1 are multiplied with the transparency of all of the Shape.fill or Shape.stroke or TextBlock.stroke or GraphObject.background within that panel or that layer.
thank you - will give it a try tonight
