cairoSurfaceHasShowTextGlyphs {RGtk2} | R Documentation

## cairoSurfaceHasShowTextGlyphs

### Description

Returns whether the surface supports sophisticated `cairoShowTextGlyphs` operations. That is, whether it actually uses the provided text and cluster data to a `cairoShowTextGlyphs` call.

### Usage

    cairoSurfaceHasShowTextGlyphs(surface)

### Arguments

``surface`` | [`CairoSurface`] a `CairoSurface`

### Details

Note: Even if this function returns `FALSE`, a `cairoShowTextGlyphs` operation targeted at `surface` will still succeed. It just will act like a `cairoShowGlyphs` operation. Users can use this function to avoid computing UTF-8 text and cluster mapping if the target surface does not use it. Since 1.8

### Value

[logical] `TRUE` if `surface` supports `cairoShowTextGlyphs`, `FALSE` otherwise
