Method

PangoLayoutget_extents

Declaration [src]

void
pango_layout_get_extents (
  PangoLayout* layout,
  PangoRectangle* ink_rect,
  PangoRectangle* logical_rect
)

Description [src]

Computes the logical and ink extents of layout.

Logical extents are usually what you want for positioning things. Note that both extents may have non-zero x and y. You may want to use those to offset where you render the layout. Not doing that is a very typical bug that shows up as right-to-left layouts not being correctly positioned in a layout with a set width.

The extents are given in layout coordinates and in Pango units; layout coordinates begin at the top left corner of the layout.

Parameters

`ink_rect`	`PangoRectangle`
	Rectangle used to store the extents of the layout as drawn.
	The argument will be set by the function.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`logical_rect`	`PangoRectangle`
	Rectangle used to store the logical extents of the layout.
	The argument will be set by the function.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
