Set display orientation during running about guix

[jdeere5220]

I will add this our our backlog. However, be advised that in order to implement 90/180/270 degree rotation with no runtime overhead, we utilize GUIX Studio to produce the resource data in the rotated format. So supporting this application requires configuring each rotation as a different display in the GUIX Studio project, and producing a resource file and display instance for each rotation angle. So at runtime, you would actually switch your display instance (resources are linked to a display). Does that help?

Hi jeddre5220,
Thanks for your reply.
Designing an respective instance for 0/90/180/270 degrees is a solution, but code will be increased. If the 0/180 degree interface can share the same resource and instance, code will be greatly reduced. So is 90/270 degrees. If API can provide rotation function, GUIX studio can design two interface instances for 0 and 90 degrees, in this way code can be half reduced at least. What do you think about this suggestion?
Thanks.

The way our code generation for rotated display works today, we want to be able to fully utilize any underlying hardware accelleration for 0/90/180/270 rotation, so we generate the resource data such that it can be streamed out in all rotation angles just like it is done for no rotation. I have added this suggestion to our backlog but I can't say how quickly we can investigate further.
