Convert PHM to PALM

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 PALM file extension, standing for Palm Pixmap, is a bitmap image format used by Palm OS mobile devices. It stores logos, clipart, photos, and other images for display in Palm OS applications. Originating from the now-discontinued Palm OS, the PALM format evolved through several versions, with later iterations supporting transparency and run-length encoding compression. PALM files are compatible with various operating systems, including Windows, Linux, and Mac OS, and can be opened and converted using tools.
