Convert PHM to MNG

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 MNG (Multiple-image Network Graphics) file extension is a specialized format for animated images, originating from the creators of the PNG format. Developed in 1999, MNG supports features like image sequences, transparency, and JPEG data embedding, making it useful for complex animations and graphics interchange. Primarily utilized in web applications and multimedia presentations, it offers efficient compression and high-quality visual representation, catering to the needs of graphics-intensive environments.
