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