cairoTextExtents {RGtk2} | R Documentation

## cairoTextExtents

### Description

Gets the extents for a string of text. The extents describe a user-space rectangle that encloses the "inked" portion of the text, (as it would be drawn by `cairoShowText`). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by `cairoShowText`.

### Usage

    cairoTextExtents(cr, utf8)

### Arguments

``cr`` | [`Cairo`] a `Cairo`
``utf8`` | [char] a string of text encoded in UTF-8, or `NULL`

### Details

Note that whitespace characters do not directly contribute to the size of the rectangle (extents.width and extents.height). They do contribute indirectly by changing the position of non-whitespace characters. In particular, trailing whitespace characters are likely to not affect the size of the rectangle, though they will affect the x_advance and y_advance values.

### Value

A list containing the following elements:

``extents`` | [`CairoTextExtents`] a `CairoTextExtents` object into which the results will be stored
