调整图片大小

Tinify CDN 可以即时调整图片大小。特别是，它可以将图片调整为较小的版本，例如缩略图。

示例

可通过在图片URL中添加查询字符串参数来调整图片大小。以下示例将把imagepanda.PNG的宽度缩小至100像素，并相应调整高度。

https://xxxxxxxx.tinifycdn.com/panda.png?resize.width=100

多个查询字符串参数可以组合使用：

https://xxxxxxxx.tinifycdn.com/panda.png?resize.width=100&resize.height=50&resize.method=fit

参数resize.method描述了图片的调整大小方式。可用的方法如下。

resize.method=scale: Scales the image down proportionally. You must provide either a target resize.width or a target resize.height parameter, but not both. The scaled image will have exactly the provided width or height.
resize.method=fit: Scales the image down proportionally so that it fits within the given dimensions. You must provide both a resize.width and resize.height parameter. The scaled image will not exceed either of these dimensions.
resize.method=cover: Scales the image proportionally and crops it if necessary so that the result has exactly the given dimensions. You must provide both a resize.width and resize.height parameter. The parts of the image that are cropped away are determined automatically. An intelligent algorithm determines the most important areas of your image.
resize.method=thumb: A more advanced implementation of cover that also detects cut-out images with plain backgrounds. The image is scaled down to the resize.width and resize.height you provide. If an image is detected with a free-standing object it will add more background space where necessary or crop the unimportant parts.
