Convert PHM to SVGZ

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.

SVGZ, or Scalable Vector Graphics Compressed, is a file extension for compressed SVG files, utilizing the GZIP compression method. Introduced to optimize web performance, SVGZ retains the scalability and resolution independence of SVG while reducing file size, leading to faster load times and reduced bandwidth usage. This format is particularly valuable in web development, digital graphics, and applications requiring efficient transmission and rendering of vector graphics. SVGZ emerged as part of efforts to enhance web technologies, catering to the increasing demand for high-quality, scalable visuals in a more efficient manner.
