-
ImageResizer
Add commands to image URLs to get altered versions in milliseconds. Resizing, editing etc of images in real-time. -
TeximpNet
A cross-platform .NET Standard library for reading/manipulating/writing image files. The primary focus is to create 2D/3D/Cubemap textures for graphics/game applications, notably to convert images to GPU compressed formats and generate mipmaps. The library wraps the FreeImage native library to import/export over 30 common image formats, and wraps the Nvidia Texture Tools native library for GPU compression features. It also has a fully featured DDS format importer/exporter written in C#.

README
DotImaging - .NET array as imaging object
The framework sets focus on .NET native array as primary imaging object, offers extensibility support via extensions, and provides unified platform-abstract imaging IO API.
News
- 5.2.0 version came out (19/02/2019)
- Image enchacement library for DotImaging: DotDevignetting!
So why DotImaging ?
- Image as native .NET 2D array
- portable*
- lightweight
- extensions, extensions, extensions....
*IO and Drawing assemlies depend on OpenCV
Libraries / NuGet packages
Core
-
.NET image array extensions. Color and depth conversions. Slim unmanaged structure for fast pixel manipulation.
Tutorial: Portable Generic Image
//convert to grayscale and flip
Bgr<byte>[,] image = ImageIO.LoadColor("sample.jpg"); //IO package
Gray<byte>[,] grayIm = image.ToGray()
.Flip(FlipDirection.Horizontal);
//get the modified blue channel
var modifiedImage = image.AsEnumerable()
.Select(x => x.B / 2)
.ToArray2D(image.Size());
-
Portable 2D drawing primitives (Extensions for Point, Size, Rectangle and additional primitives)
IO
-
A unified API for IO image access (camera, file, image directory). Portable image loading/saving.
Tutorial: Portable Imaging IO
var reader = new FileCapture("sample.mp4");
reader.Open();
Bgr<byte>[,] frame = null;
while(true)
{
reader.ReadTo(ref frame);
if (frame == null)
break;
frame.Show(scaleForm: true); //UI package
}
reader.Close();
-
Image or video download/streaming (direct video link or Youtube links).
//------get an image from the Web
new Uri("http://vignette3.wikia.nocookie.net/disney/images/5/5d/Lena_headey_.jpg")
.GetBytes().DecodeAsColorImage().Show(); //(Show - UI package)
//------stream a video from Youtube
var pipeName = new Uri("https://www.youtube.com/watch?v=Vpg9yizPP_g").NamedPipeFromYoutubeUri(); //Youtube
var reader = new FileCapture(String.Format(@"\\.\pipe\{0}", pipeName)) //IO package
//... (regular stream reading - see IO package sample)
Interoperability
-
Interoperability extensions between .NET array and System.Drawing.Bitmap.
var image = new Gray<byte>[240, 320];
var bmp = image.ToBitmap(); //to Bitmap
var imageFromBmp = bmp.ToArray() as Bgr<byte>[,]; //from Bitmap
Extensions
-
Image preview dialog and drawing.
Bgr<byte>[,] image = new Bgr<byte>[480, 640];
image.Show(); //show image (non-blocking)
image.ShowDialog(); //show image (blocking)
//draw something
image.Draw(new Rectangle(50, 50, 200, 100), Bgr<byte>.Red, -1);
image.Draw(new Circle(50, 50, 25), Bgr<byte>.Blue, 5);
Getting started
- Just pick what you need. An appropriate readme file will be shown upon selected NuGet package installation.

Final word
If you like the project please star it in order to help to spread the word. That way you will make the framework more significant and in the same time you will motivate me to improve it, so the benefit is mutual.
