    Advanced Image Compression


    Advanced image compression allows you to easily convert images into formats that provide a high compression ratio, such as TPG and HEIF. This effectively reduces the transmission time, loading time, and the use of bandwidth and traffic.

    Sample code: performing advanced image compression upon download

    String bucket = "examplebucket-1250000000"; // Bucket, formatted as BucketName-APPID
    String cosPath = "exampleobject"; // The location identifier of the object in the bucket, i.e., the object key
    String savePath = context.getExternalCacheDir().toString(); // Local path
    GetObjectRequest getObjectRequest = new GetObjectRequest(bucket, cosPath,
    getObjectRequest.addQuery("imageMogr2/format/tpg", null);
    cosXmlService.getObjectAsync(getObjectRequest, new CosXmlResultListener() {
       public void onSuccess(CosXmlRequest cosXmlRequest,
                             CosXmlResult cosXmlResult) {
           GetObjectResult getObjectResult = (GetObjectResult) cosXmlResult;
        // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
       // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
       public void onFail(CosXmlRequest cosXmlRequest,
                          @Nullable CosXmlClientException clientException,
                          @Nullable CosXmlServiceException serviceException) {
           if (clientException != null) {
           } else {
