pangoLayoutGetExtents {RGtk2} | R Documentation |
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.
