FAQ

ST4 to SVGZ Conversion

What are ST4 files?

An ST4 file represents a RAW image taken with an SBIG CCD camera. SBIG is a producer of astronomical instruments and ST4s most likely contain images related to some type of scientific or industrial application. They are considered rare and are probably difficult to open using regular image viewers.

What are SVGZ files?

SVGZ is an extension attached to SVG (Scalable Vector Graphics) images with GZIP compression. Such files can contain animations or interactive graphics, including vector objects, images and text, while supporting layer rendering, transparency, filter effects and several other features.
