FastBitmap

A .NET Standard library which wraps the System.Drawing.Bitmap class for improved pixel read/write performance.

Benchmarks

The benchmark graph below shows just how much faster FastBitmap is. When using the fastest mode it can see speed increases up to 20,000% on a single core. These benchmarks were taken on 9/5/2020 using a Ryzen 9 3950X 16C/32T CPU

Example

// Loads image from file.
using (FastBitmap bmp = FastBitmap.FromFile("image.png"))
{
	// Gets the color of pixel 0, 0 and sets it to pixel 1, 1.
	Color c = bmp.Get(0, 0);
	bmp.Set(1, 1, c);

	// Gets the color of pixel at index 1 and sets it to index 2.
	// Using indices is faster than coordinates.
	c = bmp.Get(1);
	bmp.Set(2, c);

	// Grabbing color from index 3 and setting it to index 4.
	// Using int (ARGB32) for color is much faster than the other methods.
	int color32 = bmp.GetI(3);
	bmp.SetI(4, color32);

	// Saves image to a file.
	bmp.Save("image0.png", ImageFormat.Png);
}
