如何在xamarin表格中绘制图像？

Question

I'm coding an application with xamarin forms and I've a problem. The goal is to have an image (from an api), detect the touch event when the user touches the screen on this image and then, draw something like an icon on the image with the coordinates catched by the touch event.

I didn't find any component that allow me to do that. Has someone an idea?

Thanks

You can set an Image for the background and use the signature pad to draw in front of it.
