Convert TGA to PHM

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 PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.
