BMP to FITS Conversion: FAQ

What are BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.

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.
