CtrlView is a fast, compact, powerful viewer/converter for different
2D/3D raster/vector file formats with the format recognition system.
It means that CtrlView analyses content of the file and defines its format.
If file format is among supported file types, CtrlView
will visualize this file in a correct form. If file type is unknown for CtrlView
it will be visualized in ASCII file form or in binary file form. Any file
also can be opened manually as ASCII or binary so you have a possibility to look
inside the file at any time.
CtrlView has batch mode for format convertion or printing.
