These four open source image editors are fit for serious use. Look closely, and you’ll find a robust and comprehensive range of image-editing features in GIMP, including photo adjustment, painting and drawing tools, and built-in plug-ins that include blur, distortions, lens effects, and more options. GIMP can be customized to closely resemble Photoshop in several ways:
Photoshop plug-ins can run in GIMP using another plug-in called PSPI. GIMP emulates Photoshop brushes and layer styles. The Photoshop interface layout can be emulated by downloading a modified version of GIMP called Gimphoto, which is based on an older version of GIMP.
Advanced users can automate GIMP actions using its built-in Script-Fu macro language or by installing Perl or Tcl programming languages. Operating systems: Windows, Mac OS X, and Linux In 2004, the Paint.NET project aimed to create a better alternative to Paint. The software has evolved so much that it now stands alone as a feature-rich image editor. Paint.NET supports some advanced image editing features, such as layers, color curves, and filter effects, plus the usual array of drawing tools and brushes. The version referred to here, 3.36, is not the latest version of Paint.NET, but the last version of this software released primarily under an open source license. Although newer versions of Paint.NET are still free, the project is no longer open source. Operating system: Windows Vector graphics are often used to design logos and models. They can be scaled and rendered at different resolutions with no loss of quality. Inkscape supports the Scalable Vector Graphics standard as well as a comprehensive set of tools for transformations, complex paths, and high-resolution rendering. Operating systems: Windows, Mac OS X, and Linux Supporting both bitmap and vector images, Krita sports an especially rich set of painting tools that simulate color blends and brush pressures particularly well-suited to illustrative artwork. Operating system: Windows, macOS, Linux
