What Is Image Processing?

Introduction

Image processing is a feature integrated in Object Storage Service (OBS). It provides stable, secure, efficient, and inexpensive image processing services. By using this feature, you can slim, crop, resize, and watermark images, as well as convert the formats of images.

You can access this feature via OBS Console and REST APIs, to process images stored in OBS anytime and anywhere and obtain the processed images right away.

Architecture

You can upload your images to OBS using OBS Console, OBS Browser+, REST APIs, or third-party clients. Before downloading and using an image, you can create an image style or pass image processing parameters to process it, such as cropping and compressing the image. After processing, you can obtain the URL of the new image. Furthermore, you can deliver the new image to Content Delivery Network (CDN) for acceleration and directly download it from CDN when needed. Figure 1 shows the flowchart of image processing.

After processing, new images will be directly displayed in a browser and are not stored in OBS, so they do not incur any storage costs.

Billing

Image processing is currently free of charge.
