#include <libgxps/gxps.h> struct GXPSDocument; guint gxps_document_get_n_pages (GXPSDocument *doc); GXPSPage * gxps_document_get_page (GXPSDocument *doc,guint n_page,GError **error); gboolean gxps_document_get_page_size (GXPSDocument *doc,guint n_page,gdouble *width,gdouble *height); gint gxps_document_get_page_for_anchor (GXPSDocument *doc,const gchar *anchor); GXPSDocumentStructure * gxps_document_get_structure (GXPSDocument *doc);
GXPSDocument represents a document in a GXPSFile. GXPSDocument
objects can not be created directly, they are retrieved from a
GXPSFile with gxps_file_get_document().
struct GXPSDocument;
The GXPSDocument struct contains only private fields and should not be directly accessed.
guint gxps_document_get_n_pages (GXPSDocument *doc);
Gets the number of pages in doc.
|
a GXPSDocument |
Returns : |
the number of pages. |
GXPSPage * gxps_document_get_page (GXPSDocument *doc,guint n_page,GError **error);
Creates a new GXPSPage representing the page at
index n_doc in doc document.
|
a GXPSDocument |
|
the index of the page to get |
|
GError for error reporting, or NULL to ignore |
Returns : |
a new GXPSPage or NULL on error.
Free the returned object with g_object_unref(). [transfer full]
|
gboolean gxps_document_get_page_size (GXPSDocument *doc,guint n_page,gdouble *width,gdouble *height);
Gets the typical size of the page at index n_page in doc document.
This function is useful to get the advisory size of pages in a document
without creating GXPSPage objects. This page size might be different than
the actual page size so page dimension might need to be updated once the
page is loaded. Advisory page sizes are not always available in doc,
in which case this function returns FALSE.
To get the authoritative size of a page you should use gxps_page_get_size()
instead.
|
a GXPSDocument |
|
the index of a page in doc
|
|
return location for the width of n_page. [out][allow-none]
|
|
return location for the height of n_page. [out][allow-none]
|
Returns : |
TRUE if the page size information is available in doc,
FALSE otherwise. |
gint gxps_document_get_page_for_anchor (GXPSDocument *doc,const gchar *anchor);
Gets the index of the page in doc where the given
anchor is.
|
a GXPSDocument |
|
the name of an anchor |
Returns : |
the page index of the given anchor. |
GXPSDocumentStructure * gxps_document_get_structure (GXPSDocument *doc);
Creates a new GXPSDocumentStructure representing the document
structure of doc.
|
a a GXPSDocument |
Returns : |
a new GXPSDocumentStructure or NULL if document doesn't have a structure.
Free the returned object with g_object_unref(). [transfer full]
