The Portable Network Graphics (PNG) file extension, established in 1996, serves as a widely-used raster graphics format that supports lossless data compression. Initially developed as a superior, patent-free replacement for the GIF format, PNG is prevalent in the IT industry for web design, digital photography, and complex graphics due to its capability to handle detailed images with transparent backgrounds and its extensive color range. Known for maintaining high-quality visuals without increasing file size significantly, PNG remains an indispensable tool in professional digital imaging and web development.
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.
