Question

我的目标是将精灵的组织转换为游戏阅读。我意识到了几个命令：

convert skin.png -resize 133% skin-resize.png
convert skin-resize.png -crop 128x128+0+0 skin-resize-crop1.png
convert skin-resize.png -crop 128x128+128+0 skin-resize-crop2.png
convert skin-resize-crop2.png skin-resize-crop1.png +append montage.png
convert montage.png -background transparent -extent 256x256 -quality 0 montage_extend.png

精灵的新组织看起来对我很好，但是我的游戏不再能识别图像，那么用Windows软件打开它就没问题了。我注意到如果我用Photoshop打开图像，那么我备份图像，没有任何修改，我的游戏识别图像。我在2张图片上做了一个“识别-verbose”以查看差异，这是我注意到的：

使用imagemagick 6.8.1-9（Windows 7）生成的

透明度看起来不同，但我不知道如何使用Image Magick转换我的图像以获得相同的结果。

PS：对不起我的英文：s

Image Magick无法读取图像（透明度？）
