Opcion Font Viewer is a Java based font viewer that allows you to view (un)installed TrueType fonts one or many at a time. Opcion Font Viewer allows you to select and save your favourite fonts, apply font styles, and set your own sample/preview text.
This is basically a very simple postscript viewer in which you can view simple postscipt pages. For reference I have attached a sample postscript file. Please abide by the structure followed in the file.
