Parameter | Description |
ObjectKey | Object name, such as folder/sample.jpg. |
/quality/<Quality> | Absolute quality of the image. The value can be 0–100. Use the value of the original image quality (default) or the specified quality, whichever is smaller. If there is an exclamation mark (!) after <Quality> (such as 90!), the specified quality value is forcibly used. |
/rquality/<quality> | Image quality relative to that of the input image. The value can be 0−100. For example, if the input image quality is 80 and rquality is set to 80, the quality of the output image will be 64 (80 * 80%). |
/lquality/<quality> | Minimum quality of the image. Value range: 0−100. If the input image quality is 85 and lquality is set to 80, the quality of the output image will be 85.If the input image quality is 60 and lquality is set to 80, the quality of the output image will be improved to 80. |
/ignore-error/1 | If this parameter is carried and the image fails to be processed because the image is too large or a parameter value exceeds the limit, the input image will be returned with no error reported. |
