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)) N� c C s< t �d|� t|d�| _|| _i | _tj| _| � |�| _ dS )z� 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.

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, and :class:`dviread.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. )r� �size�widthsr� r� r� c s� t |t�stdt|� ��|| _� | _|| _|| _|d | _zt � j �d }W n tk rf d}Y nX � fdd�t |�D �| _ d S )Nz$texname must be a bytestring, got %sg]�e��>r r c s" g | ]}d � j �|d� d? �qS )r� r � )rX �get)r' r� �r� r r r) s �z$DviFont.__init__.<locals>.<listcomp>) rn r r/ �typer� r� r� r� r� r9 rX r4 r� )r- r� r� r� r� Zncharsr r� r rK s � �zDviFont.__init__c C s( t | �t |�ko&| j|jko&| j|jkS r{ )r� r� r� �r- �otherr r r �__eq__! s � �zDviFont.__eq__c C s | � |� S r{ )r� r� r r r �__ne__% s zDviFont.__ne__c C s d� t| �j| j�S )Nz<{}: {}>)�formatr� r� r� rY r r r �__repr__( s zDviFont.__repr__c C s8 | j j�|d�}|dk r$t|| j�S t�d|| j� dS )zWidth of char in dvi units.Nz No width for char %d in font %s.r )r� rX r� r� r� r@ rA r� )r- r� rX r r r r~ + s zDviFont._width_ofc C sn g }| j jdf| j jdffD ]L\}}|�|d�}|dkrVt�d||| j� |�d� q |�t|| j �� q |S )z&Height and depth of char in dvi units.rV rW Nz No %s for char %d in font %sr ) r� rV rW r� r@ rA r� r� r� r� )r- r� �resultZmetric�namery r r r ro 3 s � � zDviFont._height_depth_ofN) r� r� r� r� � __slots__rK r� r� r� r~ ro r r r r r� � s %r� c @ s@ e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dS )�Vfa� A virtual font (\*.vf file) containing subroutines for dvi files.

(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. )�_font� _filenamec C s@ t �| �}i |_t�|�|_t|d��}|�|� W 5 Q R X |S )Nr? )�object�__new__r rL �fsdecoder rB �_parse)�clsrJ r- rC r r r r ) s zPsfontsMap.__new__c C s� t |t�st�z| j| }W nH tk rd d}|�|�d�| j�}tj |ddd�}t � |� � Y nX |j |j }}|d k r�|�d�s�t|�}|d k r�|�d�s�t|j �}|j||d�S )Na$ A PostScript file for the font whose TeX name is "{0}" could not be found in the file "{1}".

The format is, AFAIK: texname fontname [effects and filenames] Effects are PostScript snippets like ".177 SlantFont", filenames begin with one or two less-than signs. A filename ending in enc is an encoding file, other filenames are font files. This can be overridden with a left bracket: <[foobar indicates an encoding file named foobar. There is some difference between <foo.pfb and <<bar.pfb in subsetting, but I have no example of << in my TeX installation. s %|\s*$sZ (?x) (?: "<\[ (?P<enc1> [^"]+ )" | # quoted encoding marked by [ "< (?P<enc2> [^"]+.enc)" | # quoted encoding, ends in .enc "<<?

Calls :program:`kpsewhich` which is an interface to the kpathsea library [1]_. Most existing TeX distributions on Unix-like systems use kpathsea. It is also available as part of MikTeX, a popular distribution on Windows. *If the file is not found, an empty string is returned*. Parameters ---------- filename : string or bytestring format : string or bytestring Used as the value of the `--format` option to :program:`kpsewhich`. Could be e.g. 'tfm' or 'vf' to limit the search to that type of files. References ---------- ..
