Convert exr to fpx

What is the difference between .exr and .fpx?

Description: Raster image stored in the OpenEXR format, a high dynamic-range (HDR) image file format developed by Industrial Light & Magic; supports multi-layer images, lossy and lossless compression, and 16-bit and 32-bit pixels; used for storing deep raster images for high-quality graphics; used by raster graphics editing programs and imaging applications.; The FPX (FlashPix Bitmap Image File) format is a type of image file designed to support high-resolution photographs and images. Developed in the mid-1990s by a consortium including Kodak, Microsoft, Hewlett-Packard, and Live Picture Inc., the FPX format is based on the Image Content Architecture (ICA), which allows it to store multiple resolutions of an image within a single file. This makes it especially useful for efficiently viewing and editing images without requiring the full image file.
