pangoLayoutGetPixelExtents

Description

Computes the logical and ink extents of layout in device units. This function just calls pangoLayoutGetExtents followed by two pangoExtentsToPixels calls, rounding ink.rect and logical.rect such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to pangoExtentsToPixels).

Usage

pangoLayoutGetPixelExtents(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.
