      板子是t113-pro和Linux系统,现在想用lvgl实现图片利用多点触控进行放大缩小,实现效果类似于手机相册中的照片缩放查看,或者说不用lvgl去实现这个功能也行,有没有大佬给指个路,谢谢了!

        貌似lvgl不支持多点触摸,估计得用Qt

            Yes, LittlevGL doesn't support multi touch because there is nothing to use it for. Zoom and rotate could be a good purpose but they are not implemented.

            是的,LittlevGL 不支持多点触控,因为没有什么用。缩放和旋转可能是一个很好的目的,但它们没有实现。
