GIMP is very often considered and sometimes presented as an alternative to Photoshop. This application is used through Open Source operating systems such as GNU / Linux and BSD. A Windows version is also available.
GIMP 2.10 is available for download, review
The announcement of GIMP 2.10 is essential because it has taken six years since the release of version 2.8. There have been so many changes that it is difficult to name them all. However, there are some significant innovations.
GIMP 2.10, the major evolution is GEGL adoption
The significant change is the porting of a GEGL (Generic Graphics Library) graphics engine. The application had to be thoroughly revised to take advantage of hardware acceleration and Multi-Thread management. It now supports high-precision color images and previews filters on the canvas.
New tools are emerging as warps that replace the iWarp filter and the unified transformation tool. The latter allows rotation, scaling, perspective, movement, and tilting in one device. GIMP 2.10 provides advanced metadata management and supports OpenEXR and WebP formats.
The interface evolves with new symbolic themes and icons, and especially vector icons.
Also, High Dots Per Inch or HiDPI high pixel density displays are supported. This allows you to manage the size of the icons from the preferences or to take advantage of an auto-detection of the default pixel density.
Among other changes in addition to the new image formats OpenEXR, WebP, we have HGT and RGBE, enhancements to support existing image formats, a much better PSD import and editing and viewing of XMP, Exif, DICOM and IPTC metadata.
Finally, digital painters can enjoy mirror, mandala and tile painting and use MyPaint brushes in addition to existing brush formats.
You will find all the details here. GIMP 2.10 is available for download for GNU/Linux and Windows environments (coming soon).
