参数 | 含义 |
ObjectKey | 对象文件名,例如 folder/sample.jpg。 |
/quality/<Quality> | 图片的绝对质量,取值范围0 - 100,默认值为原图质量;取原图质量和指定质量的最小值;<Quality>后面加“!”表示强制使用指定值,例如: 90! 。 |
/rquality/<quality> | 图片的相对质量,取值范围0 - 100,数值以原图质量为标准。例如原图质量为80,将 rquality 设置为80后,得到处理结果图的图片质量为64(80x80%)。 |
/lquality/<quality> | 图片的最低质量,取值范围0 - 100,设置结果图的质量参数最小值。 例如原图质量为85,将 lquality 设置为80后,处理结果图的图片质量为85。 例如原图质量为60,将 lquality 设置为80后,处理结果图的图片质量会被提升至80。 |
/ignore-error/1 | 当处理参数中携带此参数时,针对文件过大导致处理失败的场景,会直接返回原图而不报错 |
