Description

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

  • Simulator in Ubuntu 20.04

What LVGL version are you using?

  • 8.3.3

What do you want to achieve?

  • How to control the degree of display of rpm_normal.png picture through mask like target.png

What have you tried so far?

I am currently using the AWTK widget library and need to migrate to LVGL 8.3.3. However, I am unable to achieve the desired image rotation, and I have not found a suitable API interface for this

Code to reproduce

Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.

The code block(s) should be formatted like:

/*You code here*/

Screenshot and/or video

If possible, add screenshots and/or videos about the current state.
