Since data are written with neither compression nor conversion, writing this file format is faster than other supported file formats in most circumstances. Hence, if an application needs to read and write all kinds of iconic HALCON objects as fast as possible and no compression is required, this format should be used. For images, all HALCON pixel types can be written. Multi-channel images are supported. The channels can have mixed pixel types but must have the same width and height. The domain of an image and its creation date are stored in the file as well. An object tuple is written into a single file. by default.
