cairoScaledFontGlyphExtents {RGtk2} | R Documentation |
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 cairo_show_glyphs.
