我想基于源图像制作大量图像！
显然，我可以在Adobe Photoshop中手动执行此操作......这需要花费大量的手动时间。
你是对的。让计算机轻松重复工作; 这就是他们擅长的。正如Tom Ruh的回答所说，你可以使用ImageMagick它。
但是，有一个问题：
幸运的是，图像分辨率为4：3，适用于所有具有相同高度和宽度的分辨率，即80x80px 100x100px等。
（强调我的）
目前尚不清楚你想要什么样的分辨率 - 如前所述的4：3，或暗示的1：1。
然而，根据您的要求最小73px和最大1000个像素和分辨率的hundereds ; 我写了一个小脚本，它应该涵盖大多数可能性（包括你想要的机会调整大小）可以通过改变一些变量来设置。
脚本，也可以从pastebin这里获得，以便于复制：
#!/bin/bash
# resizer.sh - resize target image between two resolutions
# accepts file as either first argument or by setting FILEPATH variable
# SETTINGS
SMALLEST_WIDTH=73 # px
LARGEST_WIDTH=1000 # px
FILEPATH= # set if you don't want to pass in image as argument
NUM_OF_RESOLUTIONS=100 # number of images generated; will generate between
# $SMALLEST_WIDTH and $LARGEST_WIDTH
RATIO= # set if you want to specify width/height
# (eg 1/1, 4/3, 16/9), blank is preserve current ratio
# NOTE: resizing to other aspect ratios may be slow/distorty:
# as per http://www.imagemagick.org/Usage/resize/#noaspect
# Seamless resizing (default) may be preferred, see:
# http://www.imagemagick.org/Usage/resize/#liquid-rescale
# but note it is slower, particularly as images get larger

注意：在计算值等的子壳上有点过分，但嘿嘿。如上所述，printf可以取消注释这些行以了解正在发生的事情，否则默认情况下它将根据静默规则默默运行。有些图像的尺寸不会与计算的尺寸完全一致（例如193px vs 138.54545454545454545452px），因为您无法以有用的方式获得分数像素。
