Rotate Pi image  

RE: Rotate Pi image

Usually rotating an image of  a camera is done by changing the direction of the scan. Many cameras have this built into the camera electronics. Rotating the camera scan outside of the camera would require some electronics that are usually not outside of the camera. I am also sure that a Pi camera may not have that capability.

It's certainly in the camera libraries, I haven't looked at this in connect or link but it's definitely in the libcamera api - search for raspistill.

The example call given is something like this:

raspistill -vf -hf -o image.jpg   - as opposed to  raspistill -o image.jpg

So I suspect it's just a matter of configuration.

Cheerio,

RE: Rotate Pi image

Hey, the code is opensource. You can check what other capabilities I can get access to. I am now doing another feature, so the rotation will have to wait, sorry. In the meantime. Do not argue about if it is or is not in libcamera without actually coding it. You can rotate images many ways, the question is if it's going to end up on the CPU or if it's going to be HW accelerated and therefore available on the ZeroW.

I am unsure if the libcamera utils even use libcamera directly, or if they are going through picamera2

RE: Rotate Pi image

Thank you all. It was just a suggestion, and other features are certainly more important — such as the network errors and beeping 🙂 I knew I could rotate it from either Octoprint or Astroprint (can't recall), so I thought maybe this was easy. And my main camera is a Wyze cam anyway.
