timeout

设置超时时间(时间不能小于5秒,单位:毫秒).

图片压缩参数

指定最大宽高

指定要压缩图片的最大的宽高,单位为像素。

比如原图片共有两张,分别为400*600500*600设置了compress-max-width200,则第一张图片将会被压缩到200*300,另外一张图片将会被压缩到200*240

compress-max-width

compress-max-height只能设置一个。

compress-max-height

compress-max-width只能设置一个。

compress-quality

只对jpegwebp图片有效

压缩图片的质量,可选值区间为[0, 1],默认为0.8.

需要特别注意的是,如果该配置设置为1,有可能压缩后的图片比原图片还要大。

建议在可以接受的清晰度条件下,尽可能地调低该值,这样会使图片更小,更便于传输。

以下为一个2.12M的图片在不同压缩质量下的文件大小

compress-quality 原始尺寸 压缩后的尺寸 压缩比 推荐程度
0 2.12 MB 114.61 KB 94.72%
0.2 2.12 MB 349.57 KB 83.90%
0.4 2.12 MB 517.10 KB 76.18%
0.6 2.12 MB 694.99 KB 67.99% 推荐
0.8 2.12 MB 1.14 MB 46.41% 推荐
1 2.12 MB 2.12 MB 0% 强烈不推荐
NaN 2.12 MB 2.01 MB 5.02%

从上表我们不难发现,压缩质量设置在0.60.8之间最优,但实际还需要以各项目的具体需求进行设置。标准就是只要清晰度能达到项目使用级别,则该值越小越好

compress-convert-size

只对png文件有用,如果文件原图为png格式,则超过该设置值大小的png格式图片将会被转换为jpeg格式。

以下为compress-convert-size设置为5000000(5MB)时三个不同大小的png图片转换后的文件示例

compress-convert-size 原始尺寸 压缩后的尺寸 压缩比
5MB 1.87 MB (PNG) 1.87 MB (PNG) 0%
5MB 5.66 MB (PNG) 450.24 KB (JPEG) 92.23%
5MB 9.74 MB (PNG) 883.89 KB (JPEG) 91.14%
