Node gm-调整图像大小并保留宽高比? [英] Node gm - resize image and preserve aspect ratio?

问题描述

Node gm是否内置支持在调整图像大小的同时保留宽高比(即生成缩略图)?还是应该获取图像尺寸，计算适当的比例，然后调用调整大小?

Does Node gm have built-in support for resizing an image while preserving aspect ratio (ie., generating a thumbnail)? Or should I get the image size, calculate the proper ratio, and then call resize?

乔纳森(Jonathan)的评论就是解决方案:

Jonathan's comment is the solution:

gm().resize(maxSize)

这会将图像的大小调整为宽度 maxSize .请参阅相关文档.

This resizes the image to width maxSize. See the relevant documentation.
