[IPUv3] Library Geometric Operations

[a_alquézar]

Hi everybody,

I'm searching a library that works with v4l2, and also IPUv3, and have implemented the geometric operations like:

Scale - change image content size

Rotate - change image content orientation

Reflect - flip over image contents

Translate - change image content position

Affine Transformation - general image content linear geometric transformation

Does anyone know any?

What is the best way to use correctly the ioctl to create this kind of library?

Thank you so much!
