Dvisvga is a screen-previewer for .dvi-files compiled by tex. it lets you see what your printed output will look like. you can choose between a black-and-white representation and greyscaling. you can choose an arbitrary zoom factor (at some cost of performance). you can set marks to measure distances. you can search for text strings. you may visit lots of dvi files, set bookmarks and get them saved to a startup-file. dvisvga does not support pxl-files. dvisvga ignores all 'special'-commands and has no font-replacing mechanism.
