ImageDotNet

A library for loading and saving images in .NET.

Goals

The goal of the library is to serve a purpose similar to stb_image and stb_image_write except written in C#. The goals include:

• Loading images.
• Writing images.
• Converting between different pixel formats.

Example

// Load image.png and ensure the pixel format is Rgba32.
var image = Image.LoadPng("image.png").To<Rgba32>();

// Get a pointer to the image data and pass it to glTexImage2D.
using (var data = image.GetDataPointer())
{
	glTexImage2D(GL_TEXTURE_2D, 0, (int)GL_RGBA, image.Width, image.Height, 0, GL_RGBA, GL_UNSIGNED_BYTE, (void*)data.Pointer);
}

Credits

Thanks to:

• ImageSharp from Zulkir for helping me to understand some parts of PNG decoding.
• ImageSharp from Six Labors. I took the names for the pixel formats from there.
