Returns : A GList of PopplerLinkMapping

poppler_page_free_link_mapping ()

void                poppler_page_free_link_mapping      (GList *list);

Frees a list of PopplerLinkMappings allocated by poppler_page_get_link_mapping(). It also frees the PopplerActions that each mapping contains, so if you want to keep them around, you need to copy them with poppler_action_copy().

list : A list of PopplerLinkMappings

poppler_page_get_selection_region ()

Render the selection specified by selection for page to the given cairo context. The selection will be rendered, using glyph_color for the glyphs and background_color for the selection background.

If non-NULL, old_selection specifies the selection that is already rendered to cairo, in which case this function will (some day) only render the changed part of the selection.

page : the PopplerPage for which to render selection
cairo : cairo context to render to
selection : start and end point of selection as a rectangle
old_selection : previous selection
style :
glyph_color : color to use for drawing glyphs
