void poppler_page_get_size (PopplerPage *page, double *width, double *height);
Gets the size of page
at the current scale and rotation.

A PopplerPage |
width : |
return location for the width of page
|
height : |
return location for the height of page
|
int poppler_page_get_index (PopplerPage *page);
Returns the index of page
page : |
a PopplerPage |
Returns : | index value of page
|
GdkPixbuf* poppler_page_get_thumbnail (PopplerPage *page);
Get the embedded thumbnail for the specified page. If the document
doesn't have an embedded thumbnail for the page, this function
returns NULL
.
gboolean poppler_page_get_thumbnail_size (PopplerPage *page, int *width, int *height);
Returns TRUE
if page
has a thumbnail associated with it. It also
fills in width
and height
with the width and height of the
thumbnail. The values of width and height are not changed if no
appropriate thumbnail exists.
page : |
A PopplerPage |
width : |
return location for width |
height : |
return location for height |
Returns : | TRUE , if page has a thumbnail associated with it.

GList* poppler_page_find_text (PopplerPage *page, const char *text);
A GList of rectangles for each occurance of the text on the page. The coordinates are in PDF points.
page : |
a PopplerPage |
text : |
the text to search for (UTF-8 encoded) |
Returns : | a GList of PopplerRectangle, |
void poppler_page_render_to_ps (PopplerPage *page, PopplerPSFile *ps_file);
Render the page on a postscript file
page : |
a PopplerPage |
ps_file : |
the PopplerPSFile to render to |
char* poppler_page_get_text (PopplerPage *page, PopplerRectangle *rect);
Retrieves the contents of the specified rectangle as text
page : |
a PopplerPage |
rect : |
the rectangle including the text |
Returns : | a pointer to the contents of the rectangle as a string |
GList* poppler_page_get_link_mapping (PopplerPage *page);
Returns a list of PopplerLinkMapping items that map from a
location on page
to a PopplerAction. This list must be freed
with poppler_page_free_link_mapping()
when done.
page : |
A PopplerPage |
Returns : | A GList of PopplerLinkMapping |
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 |
GdkRegion* poppler_page_get_selection_region (PopplerPage *page, gdouble scale, PopplerRectangle *selection);
Returns a region containing the area that would be rendered by
poppler_page_render_selection()
. The returned region must be freed with
gdk_region_destroy()
.
page : |
a PopplerPage |
scale : |
scale specified as pixels per point |
selection : |
start and end point of selection as a rectangle |
Returns : | a newly allocated GdkRegion |
void poppler_page_render_selection (PopplerPage *page, gdouble scale, int rotation, GdkPixbuf *pixbuf, PopplerRectangle *selection, PopplerRectangle *old_selection, GdkColor *glyph_color, GdkColor *background_color);
Render the selection specified by selection
for page
into
pixbuf
. The selection will be rendered at scale
, 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 in pixbuf
, in which case this function will (some day)
only render the changed part of the selection.
page : |
the PopplerPage for which to render selection |
scale : |
scale specified as pixels per point |
rotation : |
rotate the document by the specified degree |
pixbuf : |
pixbuf to render to |
selection : |
start and end point of selection as a rectangle |
old_selection : |
previous selection |
glyph_color : |
color to use for drawing glyphs |
background_color : |
color to use for the selection background |
