[<code><a rd-options="" href="/link/CairoScaledFont?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::CairoScaledFont">CairoScaledFont</a></code>]  a <code><a rd-options="" href="/link/CairoScaledFont?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::CairoScaledFont">CairoScaledFont</a></code>

<code>scaled.font</code>

[<code><a rd-options="" href="/link/CairoGlyph?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::CairoGlyph">CairoGlyph</a></code>]  a list of glyph IDs with X and Y offsets.

<code>glyphs</code>

[integer]  the number of glyphs in the <code>glyphs</code> list

<code>num.glyphs</code>

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 <code><a rd-options="" href="/link/cairoShowGlyphs?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::cairoShowGlyphs">cairoShowGlyphs</a></code> if the cairo
graphics state were set to the same font_face, font_matrix, ctm,
and font_options as <code>scaled.font</code>).  Additionally, the x_advance and
y_advance values indicate the amount by which the current point
would be advanced by <code><a rd-options="" href="/link/cairoShowGlyphs?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::cairoShowGlyphs">cairoShowGlyphs</a></code>.
