The ART file extension, associated with PFS: 1st Publisher, stands for "AOLpress Raster Technology". Developed by America Online (AOL), this format was designed to optimize image download speeds over slow internet connections by employing high compression ratios. ART files store single, highly compressed images, allowing for incremental rendering similar to progressive JPEGs. While it was useful in the past, the ART format has largely been replaced by more modern image formats.
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.
