cairoTextExtents {RGtk2} | R Documentation |
Gets the extents for a string of text. The extents describe a
user-space rectangle that encloses the "inked" portion of the text,
(as it would be drawn by cairoShowText
). Additionally, the
x_advance and y_advance values indicate the amount by which the
current point would be advanced by cairoShowText
.
cairoTextExtents(cr, utf8)
|
[Cairo ] a Cairo |
|
[char] a string of text, encoded in UTF-8 |
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.
