C#中pixelgrabber（Java）的等效函数是什么

Question

I want to grab all pixel values of a Bitmap image in C# and push it into a two-dimensional array. In Java, it's easy to do with the pixelgrabber function.

What is the equivalent function to pixelgrabber (Java) in C#?

Answer 1

It's GetPixel .

BitmapImage image;
image.GetPixel (0, 0);

This will work, but it's not meant for parsing the whole image (it might be slow). You need to get into unmanaged code and get a pointer to the raw data if you want the performance. A sample is in Using the LockBits method to access image data .
