A GdkColor represents a color.
When working with cairo, it is often more convenient to use a GdkRGBA instead.
typedef struct {
guint32 pixel;
guint16 red;
guint16 green;
guint16 blue;
} GdkColor;
The GdkColor structure is used to describe a color, similar to the XColor struct used in the X11 drawing API.
guint32 |
For allocated colors, the pixel value used to draw this color on the screen. Not used anymore. |
guint16 |
The red component of the color. This is a value between 0 and 65535, with 65535 indicating full intensity |
guint16 |
The green component of the color |
guint16 |
The blue component of the color |
GdkColor * gdk_color_copy (const GdkColor *color);
Makes a copy of a color structure.
The result must be freed using gdk_color_free().
|
a GdkColor |
Returns : |
a copy of color
|
void gdk_color_free (GdkColor *color);
Frees a color structure created with gdk_color_copy().
|
a GdkColor |
gboolean gdk_color_parse (const gchar *spec,GdkColor *color);
Parses a textual specification of a color and fill in the
red, green,
and blue fields of a GdkColor
structure.
The string can either one of a large set of standard names
(taken from the X11 rgb.txt 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').
gboolean gdk_color_equal (const GdkColor *colora,const GdkColor *colorb);
Compares two colors.
guint gdk_color_hash (const GdkColor *color);
A hash function suitable for using for a hash table that stores GdkColors.
|
a GdkColor |
Returns : |
The hash function applied to color
|
gchar * gdk_color_to_string (const GdkColor *color);
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.
The returned string can be parsed by gdk_color_parse().
|
a GdkColor |
Returns : |
a newly-allocated text string |
