Class Details¶

class Poppler.Page(**kwargs)¶

Bases:: GObject.Object
Abstract:: No

classmethod free_annot_mapping(list)¶

Parameters:: list ([Poppler.AnnotMapping]) – A list of Poppler.AnnotMapping s

Frees a list of Poppler.AnnotMapping s allocated by Poppler.Page.get_annot_mapping(). It also unreferences the Poppler.Annot s that each mapping contains, so if you want to keep them around, you need to reference them with GObject.Object.ref().

classmethod free_form_field_mapping(list)¶

Parameters:: list ([Poppler.FormFieldMapping]) – A list of Poppler.FormFieldMapping s

Frees a list of Poppler.FormFieldMapping s allocated by Poppler.Page.get_form_field_mapping().

classmethod free_image_mapping(list)¶

Parameters:: list ([Poppler.ImageMapping]) – A list of Poppler.ImageMapping s

Frees a list of Poppler.ImageMapping s allocated by Poppler.Page.get_image_mapping().

classmethod free_link_mapping(list)¶

Parameters:: list ([Poppler.LinkMapping]) – A list of Poppler.LinkMapping s

Frees a list of Poppler.LinkMapping s allocated by Poppler.Page.get_link_mapping(). It also frees the Poppler.Action s that each mapping contains, so if you want to keep them around, you need to copy them with Poppler.Action.copy().

classmethod free_text_attributes(list)¶

Parameters:: list ([Poppler.TextAttributes]) – A list of Poppler.TextAttributes s

Frees a list of Poppler.TextAttributes s allocated by Poppler.Page.get_text_attributes().

New in version 0.18.

classmethod selection_region_free(region)¶

Parameters:: region ([Poppler.Rectangle]) – a GLib.List of Poppler.Rectangle

Frees region

Deprecated since version 0.16: Use only to free deprecated regions created by Poppler.Page.get_selection_region(). Regions created by Poppler.Page.get_selected_region() should be freed with cairo_region_destroy() instead.

add_annot(annot)¶

Parameters:: annot (Poppler.Annot) – a Poppler.Annot to add

Adds annotation annot to self.

New in version 0.16.

find_text(text)¶

Parameters:: text (str) – the text to search for (UTF-8 encoded)
Returns:: a GLib.List of Poppler.Rectangle,
Return type:: [Poppler.Rectangle]

Finds text in self with the default options (Poppler.FindFlags.DEFAULT) and returns a GLib.List of rectangles for each occurrence of the text on the page. The coordinates are in PDF points.

find_text_with_options(text, options)¶

Parameters:

text (str) – the text to search for (UTF-8 encoded)
options (Poppler.FindFlags) – find options

Returns:

a newly allocated list of newly allocated Poppler.Rectangle. Free with g_list_free_full() using Poppler.Rectangle.free().

Return type:

[Poppler.Rectangle]

Finds text in self with the given Poppler.FindFlags options and returns a GLib.List of rectangles for each occurrence of the text on the page. The coordinates are in PDF points.

When Poppler.FindFlags.MULTILINE is passed in options, matches may span more than one line. In this case, the returned list will contain one Poppler.Rectangle for each part of a match. The function Poppler.Rectangle.find_get_match_continued() will return True for all rectangles belonging to the same match, except for the last one. If a hyphen was ignored at the end of the part of the match, Poppler.Rectangle.find_get_ignored_hyphen() will return True for that rectangle.

Note that currently matches spanning more than two lines are not found. (This limitation may be lifted in a future version.)

Note also that currently finding multi-line matches backwards is not implemented; if you pass Poppler.FindFlags.BACKWARDS and Poppler.FindFlags.MULTILINE together, Poppler.FindFlags.MULTILINE will be ignored.

New in version 0.22.

remove_annot(annot)¶

Parameters:: annot (Poppler.Annot) – a Poppler.Annot to remove

New in version 0.22.

render(cairo)¶

Parameters:: cairo (cairo.Context) – cairo context to render to

Render the page to the given cairo context. This function is for rendering a page that will be displayed. If you want to render a page that will be printed use Poppler.Page.render_for_printing() instead. Please see the documentation for that function for the differences between rendering to the screen and rendering to a printer.

render_for_printing(cairo)¶

Parameters:: cairo (cairo.Context) – cairo context to render to

Render the page to the given cairo context for printing with Poppler.PrintFlags.ALL flags selected. If you want a different set of flags, use Poppler.Page.render_for_printing_with_options().

The difference between Poppler.Page.render() and this function is that some things get rendered differently between screens and printers:

PDF annotations get rendered according to their Poppler.AnnotFlag value. For example, Poppler.AnnotFlag.PRINT refers to whether an annotation is printed or not, whereas Poppler.AnnotFlag.NO_VIEW refers to whether an annotation is invisible when displaying to the screen.
PDF supports “hairlines” of width 0.0, which often get rendered as having a width of 1 device pixel. When displaying on a screen, Cairo may render such lines wide so that they are hard to see, and Poppler makes use of PDF’s Stroke Adjust graphics parameter to make the lines easier to see. However, when printing, Poppler is able to directly use a printer’s pixel size instead.
Some advanced features in PDF may require an image to be rasterized before sending off to a printer. This may produce raster images which exceed Cairo’s limits. The “printing” functions will detect this condition and try to down-scale the intermediate surfaces as appropriate.

render_for_printing_with_options(cairo, options)¶

Parameters:

cairo (cairo.Context) – cairo context to render to
options (Poppler.PrintFlags) – print options

Render the page to the given cairo context for printing with the specified options

See the documentation for Poppler.Page.render_for_printing() for the differences between rendering to the screen and rendering to a printer.

New in version 0.16.

render_selection(cairo, selection, old_selection, style, glyph_color, background_color)¶

Parameters:

cairo (cairo.Context) – cairo context to render to
selection (Poppler.Rectangle) – start and end point of selection as a rectangle
old_selection (Poppler.Rectangle) – previous selection
style (Poppler.SelectionStyle) – a Poppler.SelectionStyle
glyph_color (Poppler.Color) – color to use for drawing glyphs
background_color (Poppler.Color) – color to use for the selection background

Render the selection specified by selection for self 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-None, 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.

render_to_ps(ps_file)¶

Parameters:: ps_file (Poppler.PSFile) – the Poppler.PSFile to render to

Render the page on a postscript file

Property Details¶

Poppler.Page.props.label¶

Name:: label
Type:: str
Default Value:: None
Flags:: READABLE
