FITS to PPM Conversion: FAQ

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.

What are PPM files?

PPM or Portable Pixelmap files are image files included in Netpbm, an open source graphics program. The other widely used Netpbm formats are PGM (Portable Graymap) and PBM (Portable Bitmap). All three are image formats and are sometimes called collectively PNMs (Portable Anymap format). While PGMs contains grayscale images, PPMs include color images and they represent intermediary files used in the conversion of less known formats using the Portable Bitmap Utilities. PPM files are mostly operated on UNIX and Intel-based platforms.
