[IPUv3] Library Geometric Operations

a_alquézar — Fri, 31 Jul 2015 10:42:33 GMT

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!

Thank you Igor, but I'm searching a library that contains and implementation of the geometric operations, described in the previous post, for the IPUv3 using ioctl, or any example with this operations implemented.

Does anyone know any?

Best rgrds,

Hi Boadrius

as these are linux examples.
