Gtatool

Gtatool provides a set of commands that manipulate GTAs on various levels: array element components, array dimensions, whole arrays, and streams of arrays. For example, you can add components to array elements, merge separate arrays into combined arrays in different ways, apply global transformations to array data, reorder the array data, and much more.

Additionally, gtatool can import from and export to many other file formats, including:

 * any kind of traditional image file formats (via ImageMagick and NetPBM)
 * any kind of remote sensing data (via GDAL)
 * medical image data in DICOM format (via DCMTK)
 * high dynamic range images and data (via OpenEXR and Pfstools)
 * MATLAB .mat files (via Matio)
 * RAT RadarTools .rat files
 * raw binary files (little/big endian, arbitrary data types)

Use gta help to get a list of all available commands, and gta help < cmd > to get help for the command < cmd >.

The gui command provides a graphical user interface for a subset of the full functionality.
