ImageMagick PNG调整大小增加文件大小
我正在使用ImageMagick调整图像大小。如果我传递-resize WxH选项，它的行为与预期一致。但如果我通过-resize WxH！ （为了在调整大小期间忽略宽高比），某些图像（尤其是PNG）的大小实际上是增加。 200k图像变为450k，170k图像变为360k等等。
I am resizing images using ImageMagick. If I pass a -resize WxH option it behaves as expected. But if I pass -resize WxH! (to ignore aspect ratio during resize), some images, especially PNGs, are actually increasing in size. A 200k image becomes 450k, a 170k image becomes 360k and so on.
任何想法为什么会出现这种情况以及如何修复它？
Any ideas why this is hapenning and how to fix it?
谢谢
经过研究，我将ImageMagick版本从6.3.7升级到6.5.6，现在它工作得很好。调整图像大小会生成较小的图像，一切正常。
After researching, I upgraded my ImageMagick version from 6.3.7 to 6.5.6, and now it is working great. Resizing images is generating smaller images and everything is OK.
