TEX to FITS Conversion: FAQ

What are TEX files?

The TEX format is associated with texture files from Corel Paint Shop Pro, a program designed for advanced image editing. The software was first released in the 1990s by Jasc Software and was acquired by Corel in 2004. Following its success among graphics designers and photographers, it had several subsequent updates and is now one of the most widely used software of its kind. TEX files contain texture that can be attached to images during digital processing, and might be difficult to open outside the program.

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.
