如何使用Image Magick批量将所有图像调整为sqares？ [英] How do I batch resize all images to sqares with Image Magick?

问题描述

行。我有一个水平图像，比如2000 x 300.我想要覆盖那个图像并创建一个2000 x 2000的新图像，旧图像中心位于中间和垂直方向，周围有白色空间。我也希望批量使用不同大小的许多不同图像。在此先感谢。

OK. I have a horizontal image, let's say 2000 x 300. I want to overwrite that image and create a new one that is 2000 x 2000 with the old image center in the middle and vertically, with white space around it. I also want to do this in batch with many different images of different sizes. Thanks in advance.

推荐答案

使用 -resize 将图片大小调整为2000x2000， -background 将背景设置为白色， -gravity 将原始图像置于画布上，并 -extent 调整画布本身的大小（如果图像最初不是正方形，则使图像位于中心）。

Use -resize to resize the image to 2000x2000, -background to set the background to white, -gravity to center the original image on the canvas, and -extent to resize the canvas itself (to cause the image to sit in the centre if it wasn't square originally).

convert [imagename] -resize 2000x2000 -background white \
                    -gravity center -extent 2000x2000 [imagename]
