Struct pango::Color [−][src]
pub struct Color(_);
Expand description
The Color
structure is used to
represent a color in an uncalibrated RGB color-space.
Implementations
Fill in the fields of a color from a string specification. The
string can either one of a large set of standard names. (Taken
from the CSS </ulink>
), or it can be a hexadecimal
value in the
form ‘#rgb’ ‘#rrggbb’ ‘#rrrgggbbb’ or ‘#rrrrggggbbbb’ where
‘r’, ‘g’ and ‘b’ are hex digits of the red, green, and blue
components of the color, respectively. (White in the four
forms is ‘#fff’ ‘#ffffff’ ‘#fffffffff’ and ‘#ffffffffffff’)
spec
a string specifying the new color
Returns
true
if parsing of the specifier succeeded,
otherwise false.
This is supported on crate feature v1_46
only.

Additionally, parse strings of the form
‘#rgba’, ‘#rrggbbaa’, ‘#rrrrggggbbbbaaaa’,
if alpha
is not None
, and set alpha
to the value specified
by the hex digits for ‘a’. If no alpha component is found
in spec
, alpha
is set to 0xffff (for a solid color).
