HarmonyOS PixelMap保存到文件时报错PackedSize outside size

62980115 输入的参数无效

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/errorcode-image-V5#section62980115-图片无效参数

请参考示例如下：

import { BusinessError } from '@ohos.base'
import { image } from '@kit.ImageKit';
import { picker } from '@kit.CoreFileKit';
import fs from '@ohos.file.fs';
import { util } from '@kit.ArkTS';

@Entry
@Component
struct Demo {
  @State imagePackerApi: image.ImagePacker = image.createImagePacker();
  @State imageSourceApi: image.ImageSource = image.createImageSource(0);

  async saveBase64Pixel() {
    let name = 'test.jpg'
    let base64 ='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr'
    let sourceTmpPath = getContext().cacheDir + '/' + name;
    console.log(`sourceTmpPath+${sourceTmpPath}`);
    let file = await fs.open(sourceTmpPath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE);
    const reg = new RegExp('data:image/\\w+;base64,');
    const base64Str = base64.replace(reg, '');
    let base64Helper = new util.Base64Helper();
    let result = base64Helper.decodeSync(base64Str);
    let arrayBuffer = result.buffer as ArrayBuffer;
    let imageSource = image.createImageSource(arrayBuffer);
    let opts: image.DecodingOptions = { editable: false }
    let pixelMap = await imageSource.createPixelMap(opts);
    const imagePacker: image.ImagePacker = image.createImagePacker();
    await imagePacker.packToFile(pixelMap, file.fd, { format: 'image/jpg', quality: 100 }, (err: BusinessError) => {
      if (err) {
        console.error(`Failed to pack the image to file.code ${err.code},message is ${err.message}`);
      } else {
        imagePacker.release(); //释放
        console.info('Succeeded in packing the image to file.');
      }
    })
  }


  build() {
    Column() {
      Button('保存').onClick(() => {
        this.saveBase64Pixel()
      })
    }
  }
}


图片格式换成jpeg，demo如下：

import { picker } from '@kit.CoreFileKit';
import fs from '@ohos.file.fs';
