A software suite for displaying, converting and editing still images stored in a raster image format. Image manipulation may be performed via the command line, API libraries, or through a simply graphical user interface. With recent development, it can now be used to store images in over 200 different image formats.

Features:

Software control through API and command line

Format conversion

Image transformation

Transparency support

Format identification

Text to image conversion

Read, process, or write mega-, giga-, or tera-pixel image sizes

Distributed pixel cache

Perceptual hash

ERDAS Imagine is a suite of geospatial data authoring software. The suite contains a raster graphics editor and remote sensing application that performs advanced remote sensing analysis and spatial modelling to create new information. ERDAS IMAGINE can also visualize results in 2D, 3D, video, and on cartographic quality map compositions. It is primarily designed for geospatial raster data processing and the creation of digital images for mapping use in GIS or CAD software.

Features:

Image Analysis, Remote Sensing

Parallel Batch Processing

Spatial Modeling

High Performance Mosaicking Engine in IMAGINE Advantage

Expanded Change Detection Tools (with Zonal Change Detection)

ERDAS ER Mapper Algorithms

Converts over 190 Image Formats to all Major File Formats, including GeoTIFF, NITF, CADRG, JPEG, JPEG2000, ECW and MrSID

Implements Comprehensive OGC Web Processing Service (WPS), Web Coverage Service (WCS), Web Mapping Service (WMS) and Catalog Services for the Web (CS-W)

GIMP is image editing software, much like Photoshop. It is a multi-platform software application primarily used for image composition and editing. The basic tool may be augmented by plug-ins and extensions that allow the use of new file formats, effects filters and batch processing capabilities. GIMP was initially created to manipulate raster images, but has been extended to provide limited vector image and moving image support. A number of free extensions are available in the plugin registry.
