Drawing some images / rectangles / circles from OpenCV in Skia is a pretty common task.
Here is an example on how to convert and draw CVImages (in a flexible fashion, eg. using AutoWidth) and pixel-based OpenCV-primitives in Skia.
It reflects the current state of the things, hopefully a more click-click-and-ready solution will be offered soon ™. Approved by @gregsn.
