Save NDArray as png image

I am looking to save an NDArray to an image.

In Python code, I used the io.imsave() method from skimage.io.

I tried using the approach shown here: https://stackoverflow.com/questions/5113919/how-to-convert-2-d-array-into-image-in-c-sharp

Basically it uses the the Bitmap method in System.Drawing.Bitmap

Is this the correct way to do this?

I tried converting the NDArray to a C# multidimensional array and then using the following type of code:

Bitmap bitmap; unsafe { fixed (int* intPtr = &integers[0,0]) { bitmap = new Bitmap(width, height, stride, PixelFormat.Format32bppRgb, new IntPtr(intPtr)); } }

However, I get this error on the "bitmap =" line: System.ArgumentException: 'Parameter is not valid.'

Ultimately I would like to compare the output from my python code to the output from my C# code to ensure that they are doing the same thing. As I stated, in Python I saved a multidimensional array to png. My thought was to do the same in C# using NumSharp, and then comparing the output images.

Thanks in advance.

The issue mentions converting a NumSharp NDArray to a C# multidimensional array and using System.Drawing.Bitmap; start by reviewing the array representation and Bitmap constructor requirements. Done means a NumSharp-compatible path can save the array as PNG and its output can be compared with the Python image.
