FAQ

KRO to FAX Conversion

What are KRO files?

KRO (Kolor Raw) is a simple, uncompressed image format created for the Kolor software, best known for its Autopano panorama stitching programs. Panoramas can be gigantic, and many common formats cannot hold pictures larger than about 30,000 pixels on a side, so the authors designed a format without such a limit. It stores color pictures with 8 or 16 bits per channel, or with floating-point numbers for high dynamic range images, with or without transparency. Because the pixels are saved without any compression, files are large, and the format is intended for temporary work between stages of processing rather than for sharing finished pictures. The panorama publishing tools of krpano can also read and write it.
