tev already supports PFM, which is very useful for quickly/easily writing out HDR images.
However, it is currently limited to monochrome or RGB. To add RGBA support, an extension exists called PF4 which adds an extra alpha channel.
You can find more details here: https://www.cse.cuhk.edu.hk/~ttwong/data/hdrfire/hdrfire.html
The only change compared to PFM is the magic keyword in the header, and the extra 4 bytes per pixel, so adding support should be fairly easy.

Thank you for creating tev!
