Function

PangoCairocreate_layout

Declaration [src]

PangoLayout*
pango_cairo_create_layout (
  cairo_t* cr
)

Description [src]

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.

Available since:1.10

Parameters

cr cairo_t
 

A Cairo context.

 The data is owned by the caller of the function.

Return value

Returns: PangoLayout
 

The newly created PangoLayout

 The caller of the function takes ownership of the data, and is responsible for freeing it.
