|
|
A module for reading dvi files output by TeX. Several limitations make
|
|||
|
|
this not (currently) useful as a general-purpose dvi preprocessor, but
|
|||
|
|
it is currently used by the pdf backend for processing usetex text.
|
|||
|
|
|
|||
|
|
Interface::
|
|||
|
|
|
|||
|
|
with Dvi(filename, 72) as dvi:
|
|||
|
|

|||
|

|

A glyph in the dvi file.
|
|||
|
|
|
|||
|
|
The *x* and *y* attributes directly position the glyph. The *font*,
|
|||
|
|
*glyph*, and *width* attributes are kept public for back-compatibility,
|
|||
|
|
but users wanting to draw the glyph themselves are encouraged to instead
|
|||
|
|
load the font specified by `font_path` at `font_size`, warp it with the
|
|||
|
|
effects specified by `font_effects`, and load the glyph specified by
|
|||
|
|
`glyph_name_or_index`.

Either the glyph name or the native charmap glyph index.
|
|||
|
|
|
|||
|
|
If :file:`pdftex.map` specifies an encoding for this glyph's font, that
|
|||
|
|
is a mapping of glyph indices to Adobe glyph names; use it to convert
|
|||
|
|
dvi indices to glyph names. Callers can then convert glyph names to
|
|||
|
|
glyph indices (with FT_Get_Name_Index/get_name_index), and load the
|
|||
|
|
glyph using FT_Load_Glyph/load_glyph.
|
|||
|
|
|
|||
|
|
If :file:`pdftex.map` specifies no encoding, the indices directly map
|
|||
|
|
to the font's "native" charmap; glyphs should directly load using
|
|||
|
|
FT_Load_Char/load_char after selecting the native charmap.

|
|||
|
|
A reader for a dvi ("device-independent") file, as produced by TeX.
|
|||
|
|
|
|||
|
|
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))
|
|||
|
|
Né c ó¦ — t j d|« t |d« | _ || _ i | _ t j | _ d| _ y)zù
|
|||
|
|
Read the data from the file named *filename* and convert
|
|||
|
|
TeX's internal units to units of *dpi* per inch.
|
|||
|
|
*dpi* only sets the units and does not limit the resolution.
|
|||
|
|
Use None to return TeX's internal units.

------

|
Page
|
|||
|
|
Details of all the text and box objects on the page.
|
|||
|
|
The Page tuple contains lists of Text and Box tuples and
|
|||
|
|
the page dimensions, and the Text and Box tuples contain
|
|||
|
|
coordinates transformed into a standard Cartesian
|
|||
|
|
coordinate system at the dpi value given when initializing.
|
|||
|
|
The coordinates are floating point numbers, but otherwise
|
|||
|
|
precision is not lost and coordinate values are not clipped to
|
|||
|
|
integers.

|

|
|
Encapsulation of a font that a DVI file can refer to.
|
|||
|
|
|
|||
|
|
This class holds a font's texname and size, supports comparison,
|
|||
|
|
and knows the widths of glyphs in the same units as the AFM file.
|
|||
|
|
There are also internal attributes (for use by dviread.py) that
|
|||
|
|
are *not* used for comparison.
|
|||
|
|
|
|||
|
|
The size is in Adobe points (converted from TeX points).
|
|||
|
|
|
|||
|
|
Parameters
|
|||
|
|
----------
|
|||
|
|
scale : float
|
|||
|
|
Factor by which the font is scaled from its natural size.
|
|||
|
|
tfm : Tfm
|
|||
|
|
TeX font metrics for this font
|
|||
|
|
texname : bytes
|
|||
|
|
Name of the font as used internally by TeX and friends, as an ASCII
|
|||
|
|
bytestring. This is usually very different from any external font
|
|||
|
|
names; `PsfontsMap` can be used to find the external name of the font.
|
|||
|
|
vf : Vf
|
|||
|
|
A TeX "virtual font" file, or None if this font is not virtual.
|
|||
|
|
|
|||
|
|
Attributes
|
|||
|
|
----------
|
|||
|
|
texname : bytes
|
|||
|
|
size : float
|
|||
|
|
Size of the font in Adobe points, converted from the slightly
|
|||
|
|
smaller TeX points.
|
|||
|
|
widths : list
|
|||
|
|
Widths of glyphs in glyph-space units, typically 1/1000ths of
|
|||
|
|
the point size.

|
|||
|
|
A virtual font (\*.vf file) containing subroutines for dvi files.
|
|||
|
|
|
|||
|
|
Parameters
|
|||
|
|
----------
|
|||
|
|
filename : str or path-like
|
|||
|
|
|
|||
|
|
Notes
|
|||
|
|
-----
|
|||
|
|
The virtual font format is a derivative of dvi:
|
|||
|
|
http://mirrors.ctan.org/info/knuth/virtual-fonts
|
|||
|
|
This class reuses some of the machinery of `Dvi`
|
|||
|
|
but replaces the `_read` loop and dispatch mechanism.
|
|||
|
|
|
|||
|
|
Examples
|
|||
|
|
--------
|
|||
|
|
::
|
|||
|
|
|
|||
|
|
vf = Vf(filename)
|
|||
|
|
glyph = vf[code]
|

----------
|

|
|
checksum : int
|
|||
|
|
Used for verifying against the dvi file.
|

design_size : int
|
|||
|
|
Design size of the font (unknown units)

Notes
|
|||
|
|
-----
|
|||
|
|
For historical reasons, TeX knows many Type-1 fonts by different
|
|||
|
|
names than the outside world. (For one thing, the names have to
|
|||
|
|
fit in eight characters.) Also, TeX's native fonts are not Type-1
|
|||
|
|
but Metafont, which is nontrivial to convert to PostScript except
|
|||
|
|
as a bitmap. While high-quality conversions to Type-1 format exist
|
|||
|
|
and are shipped with modern TeX distributions, we need to know
|
|||
|
|
which Type-1 fonts are the counterparts of which native fonts. For
|
|||
|
|
these reasons a mapping is needed from internal font names to font
|
|||
|
|
file names.
|
|||
|
|
|
|||
|
|
A texmf tree typically includes mapping files called e.g.
|
|||
|
|
:file:`psfonts.map`, :file:`pdftex.map`, or :file:`dvipdfm.map`.
|
|||
|
|
The file :file:`psfonts.map` is used by :program:`dvips`,
|
|||
|
|
:file:`pdftex.map` by :program:`pdfTeX`, and :file:`dvipdfm.map`
|
|||
|
|
by :program:`dvipdfm`. :file:`psfonts.map` might avoid embedding
|
|||
|
|
the 35 PostScript fonts (i.e., have no filename for them, as in
|
|||
|
|
the Times-Bold example above), while the pdf-related files perhaps
|
|||
|
|
only avoid the "Base 14" pdf fonts. But the user may have
|
|||
|
|
configured these files differently.
|
|||
|
|
|
|||
|
|
Examples
|
|||
|
|
--------
|
|||
|
|
>>> map = PsfontsMap(find_tex_file('pdftex.map'))
|
|||
|
|
>>> entry = map[b'ptmbo8r']
|
|||
|
|
>>> entry.texname
|
|||
|
|
b'ptmbo8r'
|
|||
|
|
>>> entry.psname
|
|||
|
|
b'Times-Bold'
|
|||
|
|
>>> entry.encoding
|
|||
|
|
'/usr/local/texlive/2008/texmf-dist/fonts/enc/dvips/base/8r.enc'
|
|||
|
|
>>> entry.effects
|
|||
|
|
{'slant': 0.16700000000000001}
|
|||
|
|
>>> entry.filename
