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)

Returns:

cairo.FontOptions

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)

Returns:

Number

Sets callback function for context to use for rendering attributes of type PANGO_ATTR_SHAPE. See PangoCairoShapeRendererFunc for details. Retrieves callback function and associated user data for rendering attributes of type PANGO_ATTR_SHAPE as set by pango_cairo_context_set_shape_renderer(), if any. if no shape rendering callback have been set.

Parameters:

Pango.Context context Required (not null)

void* data Required (not null)

Returns:

[object Object]

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)

cairo.FontOptions options Required (not null)

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)

Number dpi Required (not null)

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)

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

PANGO_ATTR_SHAPE, or NULL to disable shape rendering.

void* data Required (not null)

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

context is freed to release data, or NULL.

Returns:

none

Creates a context object set up to match the current transformation and target surface of the Cairo context. This context can then be used to create a layout using pango_layout_new(). This function is a convenience function that creates a context using the default font map, then updates it to cr. If you just need to create a layout for use with cr and do not need to access PangoContext directly, you can use pango_cairo_create_layout() instead. g_object_unref().

Parameters:

cairo.Context cr Required (not null)

Returns:

Pango.Context

Creates a layout object set up to match the current transformation and target surface of the Cairo context. This layout can then be used for text measurement with functions like pango_layout_get_size() or drawing with functions like pango_cairo_show_layout(). If you change the transformation or target surface for cr, you need to call pango_cairo_update_layout() This function is the most convenient way to use Cairo with Pango, however it is slightly inefficient since it creates a separate PangoContext object for each layout. This might matter in an application that was laying out large amounts of text. g_object_unref().

Parameters:

cairo.Context cr Required (not null)

Returns:

Pango.Layout

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)

Number x Required (not null)

Number y Required (not null)

Number width Required (not null)

Number height Required (not null)

Returns:

none

Gets a default PangoCairoFontMap to use with Cairo. Note that the type of the returned object will depend on the particular font backend Cairo was compiled to use; You generally should only use the PangoFontMap and PangoCairoFontMap interfaces on the returned object. The default Cairo fontmap can be changed by using pango_cairo_font_map_set_default(). This can be used to change the Cairo font backend that the default fontmap uses for example. object is owned by Pango and must not be freed.

Returns:

Pango.FontMap

Creates a new PangoCairoFontMap object; a fontmap is used to cache information about available fonts, and holds certain global parameters such as the resolution. In most cases, you can use pango_cairo_font_map_get_default() instead. Note that the type of the returned object will depend on the particular font backend Cairo was compiled to use; You generally should only use the PangoFontMap and PangoCairoFontMap interfaces on the returned object. be freed with g_object_unref().

Returns:

Pango.FontMap

Creates a new PangoCairoFontMap object of the type suitable to be used with cairo font backend of type fonttype. In most cases one should simply use pango_cairo_font_map_new(), or in fact in most of those cases, just use which should be freed with g_object_unref(), or NULL if the requested cairo font backend is not supported / compiled in.

Parameters:

cairo.FontType fonttype Required (not null)

Returns:

Pango.FontMap

Parameters:

cairo.Context cr Required (not null)

Pango.Font font Required (not null)

Pango.GlyphString glyphs Required (not null)

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)

Pango.LayoutLine line Required (not null)

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)

Pango.Layout layout Required (not null)

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)

Number x Required (not null)

Number y Required (not null)

Number width Required (not null)

Number height Required (not null)

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)

String text Required (not null)

Pango.GlyphItem glyph_item Required (not null)

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)

Pango.Font font Required (not null)

Pango.GlyphString glyphs Required (not null)

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)

Pango.Layout layout Required (not null)

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)

Pango.LayoutLine line Required (not null)

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)

Pango.Context context Required (not null)

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)

Pango.Layout layout Required (not null)

Returns:

none
