The current implementation can only iterate through pages in order, and does not even attempt to verify the postamble.
This class can be used as a context manager to close the underlying file upon exit. Pages can be read via iteration. Here is an overly simple way to extract text without trying to detect whitespace:
>>> with matplotlib.dviread.Dvi('input.dvi', 72) as dvi:
... for page in dvi:
... print(''.join(chr(t.glyph) for t in page.text))
A reader for a dvi ("device-independent") file, as produced by TeX.
The following pages refer to to this document either explicitly or contain code examples using this.
matplotlib.dviread.Vf
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
