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.
