如何查看位图的颜色深度?
我正在接收图片的路径.我需要知道那张图片是否是灰度的.我该怎么做?
I'm receiving the path of a picture. I would need to know if that picture is in grayScale. How can I do this?
我正在尝试使用此代码将该路径加载到位图,但它一直提示我该参数无效.
I'm trying to load that path to a Bitmap using this code, but it keeps saying me that the parameter is not valid.
Bitmap myBitmap = new Bitmap(pFilePath);
我可以从 ByteArray 中检查它是否是灰度的吗?或者有什么方法可以从位图做到这一点?那会怎样?
Can I check if it is in grayScale from a ByteArray? Or is there some way to do it from a Bitmap? How would that be?
谢谢.
