Function ScaledFont.textExtents
Gets the extents
for a string of text
. The extents
describe a
user-space rectangle
that encloses the "inked" portion of the
text
drawn at the origin (0,0) (as it would be drawn by
Context.showText
() if the cairo graphics state were set
to the same fontFace
, fontMatrix
, ctm, and fontOptions
as ScaledFont
). Additionally, the x_advance and y_advance
values indicate the amount by which the current point
would
be advanced by Context.showText
().
Note that whitespace characters do not directly contribute
to the size
of the rectangle
(extents.width and extents.height).
They do contribute indirectly by changing the position of
non-whitespace characters. In particular, trailing whitespace
characters are likely to not affect the size
of the
rectangle
, though they will affect the x_advance
and y_advance values.
