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.
View monochrome & grayscale TIFF, BMP and RAW bitmaps.
Supports uncompressed and compressed (packbits) TIFF.
Supports 2, 4 and 8 bit TIFF gray scale (un-compressed and PackBits).
File size (uncompressed) from 2 GB to 1802 GB.
Windows 7/10 64 Bit OS
Linux 64 bit
8-32 GB Installed RAM is recommended
Fast Hard Drive (SSD recommended)
2 max allowed TIFF or BMP file size of 4 GB is limited by the header - whether or not it is compressed. No limit to RAW files since there is no header. Monochrome BMP does not support compression and its header also limits the max file size to 4GB.
