Can we use images as marks?

[jama1017]

Hi!

Thanks so much for creating this great library. I wonder if it's possible to use images as marks in plots, like this example in Vega-lite: https://vega.github.io/vega-lite/docs/image.html#examples

Yes, in Graphic, Mark only determines how it is located, Shape determines how it is rendered. For the vega example, you can use a Point Mark, and write your own Shape, like this example:

graphic/example/lib/pages/polygon_custom.dart

Line 8 in 0cd16d1

class TriangleShape extends IntervalShape {

graphic/example/lib/pages/polygon_custom.dart

Line 436 in 0cd16d1

shape: ShapeEncode(value: TriangleShape()),

In your Shape subclass, you can render ImageElements
