Function pango::quantize_line_geometry [−][src]
pub fn quantize_line_geometry(thickness: &mut i32, position: &mut i32)
Expand description
Quantizes the thickness and position of a line, typically an
underline or strikethrough, to whole device pixels, that is integer
multiples of PANGO_SCALE
. The purpose of this function is to avoid
such lines looking blurry.
Care is taken to make sure thickness
is at least one pixel when this
function returns, but returned position
may become zero as a result
of rounding.
thickness
pointer to the thickness of a line, in Pango units
position
corresponding position
