HarmonyOS 是否有自定义图像分辨率的接口？

// path为已获得的沙箱路径 
const imageSource: image.ImageSource = image.createImageSource(path2); 
let decodingOptions: image.DecodingOptions = { 
    editable: true, 
    desiredPixelFormat: 3, 
} 
this.pixelmap=await imageSource.createPixelMap(decodingOptions); 
let imageInfo = await this.pixelmap.getImageInfo(); 
//计算压缩比 
let scaleX : number = 500/imageInfo.size.width; 
let scaleY : number = 500/imageInfo.size.height; 
this.pixelmap.scale(scaleX,scaleY,(err : BusinessError) => { 
    if (err) { 
        console.error("Failed to scale pixelmap."); return; 
    } else { 
        console.info("Succeeded in scaling pixelmap."); 
    } 
}); 
 
const imagePackerApi = image.createImagePacker(); 
let packOpts: image.PackingOption = { format: "image/jpeg", quality: 90 }; 
// const context: Context = getContext(this); 
// const path: string = context.cacheDir + “/pixel88.jpg”; 
// let file = fs.openSync(path, fs.OpenMode.CREATE | fs.OpenMode.READ_WRITE); 
imagePackerApi.packing( this.pixelmap, packOpts).then((data:ArrayBuffer) => { 
    console.info("Succeeded in packing the image."); 
}).catch((error: BusinessError) => { 
    console.error("Failed to pack the image. And the error is: " + error); 
})
