Problem description

A source image decoding exception occurs when you use OSS image processing.

Causes

The source image exceeds the pixel limit. OSS image processing supports source images with up to 250,000,000 pixels. Images that exceed this limit cannot be decoded.

Examples

The following GET request triggers this error because the source image has more than 250,000,000 pixels:

GET /example_image?x-oss-process=image/format,jpg HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: application/xml

Solutions

Replace the source image with one that has 250,000,000 pixels or fewer. To check the pixel count, multiply the image width by its height.

The following GET request succeeds with a compliant source image:

GET /example_image?x-oss-process=image/format,jpg HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: image/jpeg
