A file viewer, converter and slideshow program which runs in almost any resolution. Conversions can be performed blind in order to preserve colour depth or you can have the image colour reduced (where necessary) to display in the current mode. Some new features include real-time zooming, slideshow option, fullscreen display option and mosaic mode which lets you display all loaded pictures on screen at once. New to v4 is support for Parx Software's external modules which allow scanners and digitisers to input directly into BV4.
