Aspose.Drawing by: Aspose

Cross-platform System.Drawing.Common replacement. Aspose.Drawing implements most of System.Drawing API (including image manipulation, vector and text drawing) in fully managed code without any external dependencies.

Aspose.Drawing.Common package uses Aspose.Drawing namespace and can be used side-by-side with System.Drawing.Common on Windows. Aspose.Drawing for .NET is a 2D graphics library for rendering vector graphics such as lines, curves, and figures as well as text onto raster images. It allows to run your existing C# and VB Apps on various supported platforms having identical rendering results. Aspose.Drawing for .NET can be used in .NET Framework, .NET Core or Xamarin applications in Windows, Linux, Android, Azure Functions or Blazor WebAssembly. It can be safely run from any restricted environment such as Windows or ASP.NET service. With Aspose.Drawing you can create bitmaps from scratch or load from existing files; draw lines, Bézier curves, splines, arcs, rectangles, polygons, eclipses, etc.; work with graphics paths; render text with different fonts and styles. It allows using different pen widths and styles; solid, texture, gradient and hatch brushes; clipping regions and matrix transformations. Images are stored in memory as managed arrays of pixels and can be saved in various image formats including BMP, PNG, JPEG, GIF, and TIFF.

AutoMapper by: Jimmy Bogard

A convention-based object-object mapper. AutoMapper uses a fluent configuration API to define an object-object mapping strategy. AutoMapper uses a convention-based matching algorithm to match up source to destination values. Currently, AutoMapper is geared towards model projection scenarios to flatten complex object models to DTOs and other simple objects, whose design is better suited for serialization, communication, messaging, or simply an anti-corruption layer between the domain and application layer.
