Convert TGA to CALS

The Truevision Graphics Adapter (TGA) file extension, also known as TARGA (Truevision Advanced Raster Graphics Adapter), is a raster graphics file format. Introduced by Truevision Inc. in 1984, it was initially designed for their TARGA and VISTA graphic cards, which were among the first cards capable of displaying true color (24-bit) images. TGA files are widely used in various professional applications, including video editing, game development, and computer imaging, due to their ability to store high-quality graphics and support for features like alpha channels, gamma correction, and HDR imaging. TGA remains a popular choice for professionals in the industry.

The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
