所以,我想将图像调整为FIXED宽度,但比例高度.
我一直在尝试各种各样的运营商:
380x242#380x242> 380!x242 380x242 <
它们都没有达到预期的效果.有帮助吗?我希望它填充或调整宽度为380,然后调整高度/缩小高度所用的相同因子,将图像缩小或调整为380宽.

尝试使用380x
这应该将宽度调整为380px并保持原始宽高比.

"#"是Paperclip使用的参数,用于了解您是否期望裁剪图片.使用"100x100#"将缩放并将图片精确地裁剪为该尺寸.%@!<>是ImageMagick使用的Geometry String中的参数.可以使用以下ImageMagick几何字符串来调整图像大小:
根据Image Geometry的ImageMagick文档,几何参数可以是
scale% Height and width both scaled by specified percentage
scale-x%xscale-y% Height and width individually scaled by specified percent
width Height automagically selected to preserve aspect ratio
xheight Width automagically selected to preserve aspect ratio
widthxheight Maximum values of height and width given, ratio preserved
widthxheight^ Minimum values of width and height given, ratio preserved
widthxheight! Width and height emphatically given, ignore original ratio
widthxheight> Change only if an image dimension exceeds a specified dim.
widthxheight< Change only if both image dimensions exceed specified dim.
