NumSharp.Bitmap

Windows-only extensions that bridge System.Drawing.Bitmap and NumSharp's NDArray, with or without copying pixel data. Uses GDI+ via System.Drawing.Common.

This is an extension package for NumSharp — it depends on and builds on the core library.

Install

dotnet add package NumSharp.Bitmap

Windows only. System.Drawing.Common is supported on Windows only; on other platforms these APIs throw at runtime.

Quick start

using System.Drawing;
using NumSharp;
using NumSharp.Bitmap;

using var bmp = (Bitmap)Image.FromFile("input.png");

// Bitmap -> NDArray (shape [height, width, channels]); discardAlpha drops the alpha channel.
NDArray pixels = bmp.ToNDArray(copy: true, discardAlpha: true);

// ... manipulate pixels with np.* ...

// NDArray -> Bitmap
using Bitmap outBmp = pixels.ToBitmap();

Every conversion method takes a discardAlpha argument, and ToNDArray takes flat and copy flags to control raveling and whether pixel data is shared or copied.
