mupdf 1.21.1.20230112.1504

Summary

• Python bindings for the MuPDF PDF library.

• A python module called mupdf.

• Generated from the MuPDF C++ API, which is itself generated from the MuPDF C API.

• Provides Python functions that wrap most fz_ and pdf_ functions.

• Provides Python classes that wrap most fz_ and pdf_ structs.

  • Class methods provide access to most of the underlying C API functions (except for functions that don’t take struct args such as fz_strlcpy()).

• MuPDF’s setjmp/longjmp exceptions are converted to Python exceptions.

• Functions and methods do not take fz_context arguments. (Automatically-generated per-thread contexts are used internally.)

• Wrapper classes automatically handle reference counting of the underlying structs (with internal calls to fz_keep_*() and fz_drop_*()).

• Support for MuPDF function pointers with SWIG Director classes, allowing MuPDF to call Python callbacks.

• Provides a small number of extensions beyond the basic C API:

  • Some generated classes have extra support for iteration.

  • Some custom class methods and constructors.

  • Simple ‘POD’ structs have __str__() methods, for example mupdf.Rect is represented like: (x0=90.51 y0=160.65 x1=501.39 y1=215.6).

Example usage

Minimal Python code that uses the mupdf module:

import mupdf
document = mupdf.Document('foo.pdf')

A simple example Python test script (run by scripts/mupdfwrap.py -t) is:

• scripts/mupdfwrap_test.py

More detailed usage of the Python API can be found in:

• scripts/mutool.py

• scripts/mutool_draw.py

Here is some example code that shows all available information about document’s Stext blocks, lines and characters:

#!/usr/bin/env python3

import mupdf

def show_stext(document):
    '''
    Shows all available information about Stext blocks, lines and characters.
    '''
    for p in range(document.count_pages()):
        page = document.load_page(p)
        stextpage = mupdf.StextPage(page, mupdf.StextOptions())
        for block in stextpage:
            block_ = block.m_internal
            log(f'block: type={block_.type} bbox={block_.bbox}')
            for line in block:
                line_ = line.m_internal
                log(f'    line: wmode={line_.wmode}'
                        + f' dir={line_.dir}'
                        + f' bbox={line_.bbox}'
                        )
                for char in line:
                    char_ = char.m_internal
                    log(f'        char: {chr(char_.c)!r} c={char_.c:4} color={char_.color}'
                            + f' origin={char_.origin}'
                            + f' quad={char_.quad}'
                            + f' size={char_.size:6.2f}'
                            + f' font=('
                                +  f'is_mono={char_.font.flags.is_mono}'
                                + f' is_bold={char_.font.flags.is_bold}'

                                + f' ft_substitute={char_.font.flags.ft_substitute}'
                                + f' ft_stretch={char_.font.flags.ft_stretch}'
                                + f' fake_bold={char_.font.flags.fake_bold}'
                                + f' fake_italic={char_.font.flags.fake_italic}'
                                + f' has_opentype={char_.font.flags.has_opentype}'

                                + f')'
                            )

document = mupdf.Document('foo.pdf')
show_stext(document)
