Flip/Mirror Image

Description

Hello,
I searched quite some time and feel dumb, because I think this must be already implemented.
I need to mirror&flip an Image around the x-axis, (cool would be also generally an object too, but not important).
After Mirroring the Image I still need to be able to use the lv_img_set_pivot/lv_img_set_angle functions on it.

Is that already a feature or not implemented yet?

What MCU/Processor/Board and compiler are you using?

Does not matter.

What LVGL version are you using?

V9.2

What do you want to achieve?

What have you tried so far?

I tried style_transform_xxx with negative values, that did not work.
Also a bunch of other things, I can’t remember anymore.
