Imagesharp. NET Core cross-platform graphics processing library

Imagesharp is a support for the. NET core cross-platform graphics processing library, Imagesharp is Imageprocessor's. NET core cross-platform implementation.

IMAGESHARP supports the following operations:

resizing, cropping, flipping, rotation, edge detection, etc.

Supports Bmp,png,gif,jpeg encoders.

EXIF reads and writes for JPEG.

Temporarily does not support drawing, that is, can not support verification code and watermark and other operations.

Github:https://github.com/jimbobsquarepants/imagesharp

The current version is 1.0.0-alpha7.

New Project

Create a new. NET Core Console Application.

Add Reference

Because it is still alpha, it is not placed in NuGet and is https://www.myget.org/gallery/imagesharp on Myget.

Add the Imagesharp source to the NuGet package source.

Imagesharp Source Address: Https://www.myget.org/F/imagesharp

Then execute the command in the NuGet console:

Install-package imagesharp-version 1.0.0-alpha7

Writing code

First we need a diagram to place it at the root of the program command as Lena.jpg.

The sample code is as follows:

         Public Static voidMain (string[] args) {            //Read EXIF            using(FileStream input = File.openread ("lena.jpg") {image Image=NewImage (input); varEXIF =image.                Exifprofile.values; foreach(varIteminchEXIF) {Console.WriteLine (item. Tag+":"+item.                Value); }            }                        //Zoom            using(FileStream input = File.openread ("lena.jpg"))            using(FileStream output = File.openwrite ("lena2.jpg") {image Image=NewImage (input); Image. Resize (image. Width/2, image. Height/2)                     .            Save (output); }            //cropping            using(FileStream input = File.openread ("lena.jpg"))            using(FileStream output = File.openwrite ("lena3.jpg") {image Image=NewImage (input); Image. Crop (image. Width/2, image. Height/2)                     .            Save (output); }            //Rotate 180 °            using(FileStream input = File.openread ("lena.jpg"))            using(FileStream output = File.openwrite ("lena4.jpg") {image Image=NewImage (input); Image. Rotate (rotatetype.rotate180).            Save (output); }            //set the pixel point way to simply draw a blank            using(FileStream output = File.openwrite ("lena5.jpg") {image Image=NewImage (1xx, 2xx); color[] Colors=Newcolor[20000];  for(inti =0; I <20000; i++) {Colors[i]=Color.White; } image. SetPixels ( -, $, colors); Image.            Save (output);        } console.readkey (); }

Run the program in the program root directory to get the following figure

The above is the simple use of imagesharp, and more can be seen on the official GitHub.
