Question

HarmonyOS createPixelMapFromSurface接口获取pixelmap失败？

Answer 1

需要生成pixelmap，然后保存成图片存储在本地。

操作步骤：

1、调用XComponent，如下：

XComponent({
  id: XCOMPONENT_ID,
  type: XComponentType.TEXTURE,
  libraryname: LIBRARY_NAME
})
  .onLoad((xComponentContext) => {
    this.xComponentContext = xComponentContext as XComponentContext;
  })
  .onDestroy(() => {
    Logger.info(TAG, "XComponent onDestroy");
  })
  .width('100%')
  .height('100%')
  .backgroundColor(Color.Black)

2、调用createPixelMapFromSurface，如下：

image.createPixelMapFromSurface(XCOMPONENT_ID, region).then(() => {
  Logger.info(TAG, 'onTakePhoto:Succeeded in creating pixelmap from Surface');
}).catch((error: BusinessError) => {
  Logger.error(TAG, 'onTakePhoto:Failed to create pixelmap ' + JSON.stringify(error));
});

3、报错如下：

onTakePhoto:Failed to create pixelmap 62980178
