#鸿蒙通关秘籍#在HarmonyOS中如何通过effectKit调整图像的亮度？

import effectKit from '@ohos.effectKit';
import image from "@ohos.multimedia.image";

const color = new ArrayBuffer(96);
let opts = { editable: true, pixelFormat: 3, size: { height: 4, width: 6 } };
image.createPixelMap(color, opts).then((pixelMap) => {
  let bright = 0.5; // 设置亮度值
  let headFilter = effectKit.createEffect(pixelMap);
  if (headFilter != null) {
    headFilter.brightness(bright);
  }
});
