GI File – What is .gi file and how to open it?
GI File Extension
Global Image – file format by N/A
GI is the filename extension for Global Image, a 24-bit bitmap image format developed by VISTA that supports both lossy and lossless compression. GI files can be opened with a variety of software programs, including Microsoft Paint and Adobe Photoshop.
GI File Format
GI files are Global Image files, a raster image format developed by N/A. They are designed to store and transmit images efficiently, particularly for use in geographic information systems (GIS). GI files support various image compression algorithms, including lossless LZ77 compression and lossy JPEG compression. This allows for optimization of image quality and file size depending on the intended use and storage requirements.
GI files are often used in GIS applications, such as map creation, land use planning, and environmental modeling. They provide a versatile and efficient way to store and manipulate geospatial imagery, enabling users to visualize and analyze data in geographic contexts. Additionally, GI files can be easily converted to other popular image formats, such as JPEG, PNG, and TIFF, ensuring compatibility with various software and applications.
Programs That Can Open GI Files
Several software programs can open GI files, including:
-
Global Image (N/A): Global Image is the primary software used to create and open GI files. It is a raster graphics editor that supports various image formats, including GI.
-
ImageMagick (ImageMagick Studio): ImageMagick is a command-line tool and a software library for image processing. It can read, convert, and write GI files, among other image formats.
-
XnView (Pierre-Emmanuel Gougelet): XnView is a free image viewer and converter that supports over 500 image formats, including GI. It provides basic editing tools and allows for batch processing of images.
Opening GI Files
To open a GI file using one of these programs:
- Install the software on your computer.
- Launch the software.
- Go to the “File” menu and select “Open.”
- Browse to the location of the GI file and select it.
- Click on the “Open” button.
The GI file will be opened in the software, where you can view, edit, or convert it as needed. Please note that the specific features and capabilities available for GI files may vary depending on the software being used.
Global Image File Format (GI)
Global Image (GI) is a raster image file format developed by Computer Associates International, Inc. (CA). GI files are able to store images with a maximum resolution of 65,535 x 65,535 pixels and support a wide range of color depths, from 1-bit black-and-white to 24-bit full color. GI images can also be compressed using a lossless compression algorithm, making them suitable for archival purposes. However, GI files are not as widely supported as other popular image formats, such as JPEG or PNG.
Applications of GI Files
GI files are primarily used for storing and managing large, high-resolution images, such as those used in medical imaging, satellite imagery, and geological mapping. They are also used in some CAD and GIS applications. However, due to their limited compatibility with other software, GI files are not as common as other image formats.
