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 X11 <filename>rgb.txt</filename> file), or it can be a hex 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')
- Parameters
-
spec | A string specifying the new color. |
- Returns
true
if parsing of the specifier succeeded, otherwise false.
void Pango::Color::set_blue |
( |
const guint16 & |
value | ) |
|
Sets the blue component of the color.
- Parameters
-
value | The blue component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity. |
void Pango::Color::set_green |
( |
const guint16 & |
value | ) |
|
Sets the green component of the color.
- Parameters
-
value | The green component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity. |
void Pango::Color::set_red |
( |
const guint16 & |
value | ) |
|
Sets the red component of the color.
- Parameters
-
value | The red component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity. |
Returns a textual specification of color in the hexadecimal form #rrrrggggbbbb
, where r
, g
and b
are hex digits representing the red, green, and blue components respectively.
- Since pangomm 1.16:
