Convert PHM to JP2

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.

JP2 stands for JPEG 2000, developed by the Joint Photographic Experts Group. It's a file format designed for high-quality image compression, supporting both lossy and lossless compression. Introduced in the year 2000, JP2 offers superior image quality and efficient storage over the standard JPEG format, making it suitable for medical imaging, digital cinema, and archives requiring high-fidelity imagery. Its advanced features include better handling of color, metadata, and progressive decoding, ensuring it remains a vital tool in professional and technical applications.
