Embedded in a geoPDF is info on the CTM - Coordinate Transformation Matrix.
I am unfamiliar with this CTM.
I know how to use python-numpy.
How (or is it even possible) for me to use the CTM information to get the latitude and longitude bounding box of the image?
Is more information need such as the pixel bounding box of the image?
Is there a simple matrix calculation some one can explain to me that I can do in numpy?
