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.

There is no shadow property for a line. What you can do is drawing a line on a canvas and blur it.

See this example as a reference.

Thanks,
This way is useful, but when i rotating the canvas causes a splash screen. The canvas buf used “LV_CANVAS_BUF_SIZE_TRUE_COLOR_ALPHA” , and LV_COLOR_DEPTH = 16.

Solved！The previous error is because i didn’t keep cbuf_tmp and cbuf as same size .
