Retrieves any font rendering options previously set with
pango_cairo_font_map_set_font_options(). This function does not report options
that are derived from the target surface by pango_cairo_update_context()
if no options have been set. This value is owned by the context
and must not be modified or freed.

Parameters:

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

Returns:

cairo.FontOptions the font options previously set on the context, or NULL

Gets the resolution for the context. See pango_cairo_context_set_resolution()
be returned if no resolution has previously been set.

Parameters:

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

Returns:

gdouble the resolution in "dots per inch". A negative value will

Sets the font options used when rendering text with this context.
These options override any options that pango_cairo_update_context()
derives from the target surface.

Parameters:

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

cairo.FontOptions options Required (not null)

a cairo_font_options_t, or NULL to unset any previously set options. A copy is made.

Returns:

none

Sets the resolution for the context. This is a scale factor between
points specified in a PangoFontDescription and Cairo units. The
default value is 96, meaning that a 10 point font will be 13
units high. (10 * 96. / 72. = 13.3).

Parameters:

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

gdouble dpi Required (not null)

the resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.) A 0 or negative value means to use the resolution from the font map.

Returns:

none

Sets callback function for context to use for rendering attributes
of type PANGO_ATTR_SHAPE. See PangoCairoShapeRendererFunc for
details.

Parameters:

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

Function (Context cr, AttrShape attr, gboolean do_path, void* data) : none Required (not null)

Callback function for rendering attributes of type PANGO_ATTR_SHAPE, or NULL to disable shape rendering.

void* data Required (not null)

User data that will be passed to func.

Function (void* data) : none Required (not null)

Callback that will be called when the context is freed to release data, or NULL.

Returns:

none

Add a squiggly line to the current path in the specified cairo context that
approximately covers the given rectangle in the style of an underline used
to indicate a spelling error. (The width of the underline is rounded to an
integer number of up/down segments and the resulting rectangle is centered
in the original rectangle)

Parameters:

cairo.Context cr Required (not null)

a Cairo context

gdouble x Required (not null)

The X coordinate of one corner of the rectangle

gdouble y Required (not null)

The Y coordinate of one corner of the rectangle

gdouble width Required (not null)

Non-negative width of the rectangle

gdouble height Required (not null)

Non-negative height of the rectangle

Returns:

none

Adds the glyphs in glyphs to the current path in the specified
cairo context. The origin of the glyphs (the left edge of the baseline)
will be at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Font font Required (not null)

a PangoFont from a PangoCairoFontMap

Pango.GlyphString glyphs Required (not null)

a PangoGlyphString

Returns:

none

Adds the text in PangoLayoutLine to the current path in the
specified cairo context. The origin of the glyphs (the left edge
of the line) will be at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.LayoutLine line Required (not null)

a PangoLayoutLine

Returns:

none

Adds the text in a PangoLayout to the current path in the
specified cairo context. The top-left corner of the PangoLayout
will be at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Layout layout Required (not null)

a Pango layout

Returns:

none

Draw a squiggly line in the specified cairo context that approximately
covers the given rectangle in the style of an underline used to indicate a
spelling error. (The width of the underline is rounded to an integer
number of up/down segments and the resulting rectangle is centered in the
original rectangle)

Parameters:

cairo.Context cr Required (not null)

a Cairo context

gdouble x Required (not null)

The X coordinate of one corner of the rectangle

gdouble y Required (not null)

The Y coordinate of one corner of the rectangle

gdouble width Required (not null)

Non-negative width of the rectangle

gdouble height Required (not null)

Non-negative height of the rectangle

Returns:

none

Draws the glyphs in glyph_item in the specified cairo context,
embedding the text associated with the glyphs in the output if the
output format supports it (PDF for example), otherwise it acts
similar to pango_cairo_show_glyph_string().
The origin of the glyphs (the left edge of the baseline) will
be drawn at the current point of the cairo context.
Note that text is the start of the text for layout, which is then
indexed by glyph_item->item->offset.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

String text Required (not null)

the UTF-8 text that glyph_item refers to

Pango.GlyphItem glyph_item Required (not null)

a PangoGlyphItem

Returns:

none

Draws the glyphs in glyphs in the specified cairo context.
The origin of the glyphs (the left edge of the baseline) will
be drawn at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Font font Required (not null)

a PangoFont from a PangoCairoFontMap

Pango.GlyphString glyphs Required (not null)

a PangoGlyphString

Returns:

none

Draws a PangoLayout in the specified cairo context.
The top-left corner of the PangoLayout will be drawn
at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Layout layout Required (not null)

a Pango layout

Returns:

none

Draws a PangoLayoutLine in the specified cairo context.
The origin of the glyphs (the left edge of the line) will
be drawn at the current point of the cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.LayoutLine line Required (not null)

a PangoLayoutLine

Returns:

none

Updates a PangoContext previously created for use with Cairo to
match the current transformation and target surface of a Cairo
context. If any layouts have been created for the context,
it's necessary to call pango_layout_context_changed() on those
layouts.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Context context Required (not null)

a PangoContext, from a pangocairo font map

Returns:

none

Updates the private PangoContext of a PangoLayout created with
pango_cairo_create_layout() to match the current transformation
and target surface of a Cairo context.

Parameters:

cairo.Context cr Required (not null)

a Cairo context

Pango.Layout layout Required (not null)

a PangoLayout, from pango_cairo_create_layout()

Returns:

none
