Method

GdkRGBAto_string

Declaration [src]

char*
gdk_rgba_to_string (
  const GdkRGBA* rgba
)

Description [src]

Returns a textual specification of rgba in the form rgb(r,g,b) or rgba(r,g,b,a), where “r”, “g”, “b” and “a” represent the red, green, blue and alpha values respectively. “r”, “g”, and “b” are represented as integers in the range 0 to 255, and “a” is represented as a floating point value in the range 0 to 1.

These string forms are string forms that are supported by the CSS3 colors module, and can be parsed by gdk_rgba_parse().

Note that this string representation may lose some precision, since “r”, “g” and “b” are represented as 8-bit integers. If this is a concern, you should use a different representation.

Return value

Type: char*

A newly allocated text string.

The caller of the method takes ownership of the returned data, and is responsible for freeing it.

The value is a NUL terminated UTF-8 string.
