The Vimba Python API is optimized for quick and easy prototyping. To migrate to the Vimba C API, we recommend using Vimba Python's extensive logging capabilities. In the log file, the order of operations is the same as in the Vimba C API. Migrating to the Vimba C++ API is eased by similar names of the functions.

http://5y1.org/file/11170/geometric-transformations-and-thresholding-of-images-using.pdf
OpenCV gives two change capacities, cv2.warpAffine and cv2.warpPerspective, with which you can have a wide range of changes. cv2.warpAffine takes a 2x3 change grid while cv2.warpPerspective takes a 3x3 change framework as information. Scaling is simply resizing of the picture. OpenCV accompanies a capacity cv2.resize() for this reason.
