Convert DIB to PHM

A Device Independent Bitmap (DIB) is a format for storing bitmap graphics, ensuring compatibility across different devices and platforms. Its primary use is to enable consistent image representation, regardless of the display hardware or software. Originating from early Windows operating systems, DIBs allowed developers to create graphics that would render accurately on various hardware. Today, DIBs are integral in applications needing uniform image display and manipulation, maintaining their relevance in diverse technological contexts.

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.
