Bindings to the poppler PDF library via the Glib interface. Allows querying of a PDF file structure and rendering to various output targets.
Poppler module provides complete bindings to the poppler PDF library through the Glib interface. Find out more about poppler at http://poppler.freedesktop.org.
As of version 1.01, no XS is used directly but bindings are provided using GObject introspection and the Glib::Object::Introspection module. See the "SYNOPSIS" in Poppler for a brief example of how the module can be used. For detailed documentation on the available classes and methods, see the poppler glib documentation for the C libraries and the Glib::Object::Introspection documentation for a description of how methods are mapped between the C libraries and the Perl namespace.
- new_from_file ($filename)
Takes a system path or URI to a PDF file as an argument and returns a Poppler::Document object. The
poppler-gliblibrary itself requires a full URI (e.g. "file:///home/user/file.pdf") but this module attempts to convert regular system paths if provided via the URI module.
- new_from_data ($data)
Takes a PDF data chunk as an argument and returns a Poppler::Document object.
For details on the classes and methods available beyond the constructors listed above, please refer to the canonical documentation for the C library listed under "SEE ALSO" in Poppler. A general discussion of how these classes and methods map to the Perl equivalents can be found in the Glib::Object::Introspection documentation. Generally speaking, a C function such as 'poppler_document_get_title' would map to 'Poppler::Document->get_title'.
In order to make things more Perlish,
Poppler customizes the API generated by Glib::Object::Introspection in a few spots:
The array ref normally returned by the following functions is flattened into a list:
The following functions normally return a boolean and additional out arguments, where the boolean indicates whether the out arguments are valid. They are altered such that when the boolean is true, only the additional out arguments are returned, and when the boolean is false, an empty list is returned.
Perl reimplementations of
Poppler::Document::save_a_copyare provided which remove the need to provide filenames as URIs (e.g. "file:///absolute/path"). The module accepts either real URIs or regular system paths and will convert as necessary using the
URImodule. Any of these formats should work:
$p = Poppler::Document->new_from_file( 'file:///home/user/file.pdf' ); $p = Poppler::Document->new_from_file( '/home/user/file.pdf' ); $p = Poppler::Document->new_from_file( 'file.pdf' ); # likewise for save() # likewise for save_a_copy()
