Is there a way to know the image size of the output model? #157

I am interested in using pyRender.

Is there a way to know the image size of the output model when rendering a 3D model? As a reason for the question, I would like to cut out the image of the output model and use it. This is because it is necessary to prepare many images for AI learning.

As a method I am thinking about, if I can know the size of the output image of the model, for example, I think of a method of adjusting the camera position using the Rotation.from_rotvec method so that it is drawn in the size of W128 ✖ H128 dots. I am.

Best regards

So you want to, crop the rendered frame to tightly bound the 3D object? If you have a unique colored background, could just filter it out using some edge detection.
