From 5c32a0daf5c3ce59491b043bd2e3efd1f7a7d224 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Mon, 7 Sep 2020 08:16:02 +0100 Subject: libcamera: raspberrypi: Plumb user transform through to IPA This commit plumbs the user transform from the Raspberry Pi pipeline handler through to the IPA. Note that the transform is actually handled in the sensor (by setting the h/v flip bits), so the IPAs need to understand the orientation of the image they receive. Once in the IPA we add it to the CameraMode description, so that it becomes automatically available to all the individual control algorithms. The IPA configure method has to be reordered just a little so as to fill in the transform in the camera mode before calling SwitchMode.
