Convert PHM to UBRL6

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.

The UBRL6 file extension, short for Unicode Braille 6 Dots, is a text encoding format that uses a 6-dot braille cell to represent characters, symbols, and punctuation marks. It enables the conversion of text into a tactile code system, facilitating reading for individuals with visual impairments. UBRL6 supports both uncontracted and contracted braille fonts and leverages Unicode to cover a wide range of characters from different writing systems. This format is particularly useful for developers and organizations working on accessibility solutions.
