Python 为什么这些JPEG可以与平铺贴图编辑器一起工作，而不能与PNG一起工作？

我试图在pygame中显示平铺地图，我想使用PNG，因为它们是透明的。但是，当我将平铺显示在窗口上时，4/6个不同的平铺显示良好，但2个平铺不显示（顶部为草，中间为土）。当我尝试用JPEG做同样的事情时，地图显示得很好，但是因为它们不是透明的，所以我不想使用它们

这是JPEG显示的内容：

这是PNG显示的内容：

我还收到了垃圾短信：“libpng警告：iCCP：已知错误的sRGB配置文件” 但有人告诉我，这并不重要

添加png图像查看问题对不起，您能澄清一下，添加png图像是什么意思吗？使用grass添加png图像，以便我们可以使用此sRGB配置文件检查代码。也许这与这个问题有关。顺便问一下：您是否尝试过使用不同的PNG，但它不显示有关sRGB profiel的信息。或者你试着把这个PNG转换成RGB或RGBA吗？这里有一个下载链接指向一个不工作的图像：我注意到的唯一区别是工作图像和不工作的图像之间的区别，不工作的图像没有透明部分，工作的图像上有一些透明部分，如果这对atall有帮助的话。
