gdk-rgba-parse (str)

str -- a string specifying the color

A gdk-rgba color with the filled in values.

Parses a textual representation of a color, and returns a RGBA instance filling in the red, green, blue and alpha fields. The string can be either one of:

• A standard name taken from the X11 rgb.txt file.
• A hex value in the form rgb, rrggbb, rrrgggbbb or rrrrggggbbbb.
• A RGB color in the form rgb(r,g,b). In this case the color will have full opacity.
• A RGBA color in the form rgba(r,g,b,a).

Where r, g, b and a are respectively the red, green, blue and alpha color values. In the last two cases, r, g and b are either integers in the range 0 to 255 or precentage values in the range 0% to 100%, and a is a floating point value in the range 0.0 to 1.0.
