推荐答案

我不是 Python 专家，但你可以试试:

I am no expert in Python but you could try:

将图像的颜色乘以0.1、0.2、0.3(小于1的任何值)之类的值，这将为您提供非常暗的纹理.这将是最简单的方法，因为它只涉及减少该纹理的颜色值.

Multiply the color of the image by a value like 0.1, 0.2, 0.3 (anything less that 1) which will give you a very dark texture. This would be the easiest method as it involves just reducing the color values of that texture.

或者您可以尝试更复杂的方法，例如在原始图像上绘制一个透明的黑色四边形，使其看起来像是在阴影中.

Or you could try a more complex method such as drawing a transparent black quad over the original image to give it the illusion of being in a shadow.
