Background on downloading image

GoJS
1

Hi Walter. I use Diagram.makeImageData and wanna set on background gradient. In documentation I did not find any resolves. Are there any ideas to create it? I thing using go.Brush but background may be only css color.

Yes, makeImageData only accepts CSS color strings or null for the background option.

I suppose you could temporarily place in the “Grid” Layer a Part holding a Shape that has the Brush that you want to use. You’ll need to set that Part’s position and that Shape’s desiredSize to match the area that you wanted to render.
