dvgt – Previewer for use on graphic and character-cell terminals
Dvgt is a development of DVItoVDU, a very early previewer.
Dvgt has Terse, Box and Full preview modes. Terse mode uses the
text mode of the VDU, and is insensitive to zoom. Box mode shows
the bounding boxes of characters. Full mode gives a graphically
rendered preview. On non-graphic terminals at low screen
magnifications, Terse mode is the most useful, but as one zooms
in, Box and Full modes become more and more accurate.
