Hi,
not sure whether this is definitely a “Bug” or rather a “Missing feature” or even left out deliberately. Marked it as “Bug” for now.
I’m extensively using the tmxrasterizer application to create preview images for all the maps that are used in my game. Here I found that it does not resolve template objects and is therefore not able to draw objects which are originating from tile images.
I’ve compiled that project locally and updated the tmxrasterizer application to resolve templates. I am happy to provide a PR on the same if this desirable.
