Very Large Bitmap Viewer

VLBV is a specialized monochrome & grayscale bitmap viewer we developed specifically for testing the output of high resolution, large area rasterizers. Some of our rasterizers produce bitmaps that are 1000 mm x 1000 mm at 50,000 DPI.

We needed a way to quickly load, view, measure and compare multi-GB raster files. Unfortunately existing tools such as Photoshop® were either completely unable to load the files or ran so slow as to be unacceptable.

So we built our own viewer. Now it is available for sale to others who have similar needs.
