ImageMagick 功能强大，但似乎无法转换为彩色版本.

ImageMagick is powerful but doesn't seem capable of converting to a colourful version.

推荐答案

不幸的是，这是不可能的.灰度图像没有足够的信息来创建彩色图像.在看到黑白图像/灰度图像转换为彩色图像的情况下，这是在诸如photoshop之类的应用程序中手动完成的.

Unfortunately this is not possible. Grayscale images do not contain sufficient information to create a color image. In instances where you see B&W/Grayscale images converted to color, this has been done manually in an application such as photoshop.

您可以使用imagemagick应用滤镜，但不能重新引入颜色. http://www.imagemagick.org/Usage/color_mods/#level-colors
