Convert JIF to PHM

The JIF (Joint Photographic Experts Group Interchange Format) is a standard for compressing and encoding digital images. Initially introduced in 1992 by the Joint Photographic Experts Group, JIF became widely adopted due to its efficient lossy compression method, which significantly reduces file size without a substantial loss in image quality. Primarily used for web graphics and digital photography, JIF has influenced the development of other formats like JPEG and its various subtypes, ensuring high compatibility across different platforms and devices.

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.
