## pangoFontGetGlyphExtents

### Description

Gets the logical and ink extents of a glyph within a font. The coordinate system for each rectangle has its origin at the base line and horizontal origin of the character with increasing coordinates extending to the right and down. The functions `pangoAscent()`, `pangoDescent()`, `pangoLbearing()`, and `pangoRbearing()` can be used to convert from the extents rectangle to more traditional font metrics. The units of the rectangles are in 1/PANGO_SCALE of a device unit.

### Usage

    pangoFontGetGlyphExtents(object, glyph)

### Arguments

``object`` | [`PangoFont`] a `PangoFont`
``glyph`` | [numeric] the glyph index

### Details

If `font` is `NULL`, this function gracefully sets some sane values in the output variables and returns.

### Value

A list containing the following elements:

``ink.rect`` | [`PangoRectangle`] rectangle used to store the extents of the glyph as drawn or `NULL` to indicate that the result is not needed.
``logical.rect`` | [`PangoRectangle`] rectangle used to store the logical extents of the glyph or `NULL` to indicate that the result is not needed.
