cairoScaledFontGlyphExtents {RGtk2} | R Documentation

## cairoScaledFontGlyphExtents

### Description

Gets the extents for a list of glyphs. The extents describe a user-space rectangle that encloses the "inked" portion of the glyphs, (as they would be drawn by `cairoShowGlyphs` if the cairo graphics state were set to the same font_face, font_matrix, ctm, and font_options as `scaled.font`). Additionally, the x_advance and y_advance values indicate the amount by which the current point would be advanced by `cairoShowGlyphs`.

### Usage

    cairoScaledFontGlyphExtents(scaled.font, glyphs, num.glyphs)

### Arguments

``scaled.font`` | [`CairoScaledFont`] a `CairoScaledFont`
``glyphs`` | [`CairoGlyph`] a list of glyph IDs with X and Y offsets.
``num.glyphs`` | [integer] the number of glyphs in the `glyphs` list

### Details

Note that whitespace glyphs do not contribute to the size of the rectangle (extents.width and extents.height).

### Value

A list containing the following elements:

``extents`` | [`CairoTextExtents`] a `CairoTextExtents` which to store the retrieved extents.
