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 specification</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.

(White in the four forms is ‘#fff’ ‘#ffffff’ ‘#fffffffff’ and ‘#ffffffffffff’)

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).

true if parsing of the specifier succeeded, otherwise false.

alpha

return location for alpha, or None
