pangoLayoutGetExtents: pangoLayoutGetExtents

Description

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.

Usage

pangoLayoutGetExtents(object)

Arguments

object

[PangoLayout] a PangoLayout

Value

A list containing the following elements:

ink.rect

[PangoRectangle] rectangle used to store the extents of the layout as drawn or NULL to indicate that the result is not needed.

logical.rect

[PangoRectangle] rectangle used to store the logical extents of the layout or NULL to indicate that the result is not needed.

Details

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