GDK Reference Manual

　　colormap : a GdkColormap.

　　Returns : the visual of the colormap.

gdk_colors_store ()
voidgdk_colors_store(GdkColormap *colormap,
GdkColor *colors,gint ncolors); 

　　Change the value of the first ncolors colors in a private colormap. This function is obsolete and should not be used. See gdk_color_change().

　　colormap : a GdkColormap.

　　colors : the new color values.

　　ncolors : the number of colors to change.

gdk_color_copy ()
GdkColor* gdk_color_copy(GdkColor *color); 

　　Make a copy of a color structure. The result must be freed using gdk_color_free().

　　color : a GdkColor.

　　Returns : a copy of color.

gdk_color_free ()
voidgdk_color_free(GdkColor *color); 

　　Free a color structure created with gdk_color_copy().

　　color : a GdkColor.

gdk_colors_alloc ()
gbooleangdk_colors_alloc(GdkColormap *colormap,
gint contiguous,gulong *planes,gint nplanes,gulong *pixels,gint npixels); 

　　Allocate colors from a colormap. This function is obsolete. See gdk_colormap_alloc_colors(). For full documentation of the fields, see the Xlib documentation for XAllocColorCells.

　　colormap : a GdkColormap.

　　contiguous : if TRUE, the colors should be allocated in contiguous color cells.

　　planes : an array in which to store the plane masks.

　　nplanes : the number of planes to allocate. (Or zero, to indicate that the color allocation should not be planar.)

　　pixels : an array into which to store allocated pixel values.

　　npixels : the number of pixels in each plane to allocate.

　　Returns :

gdk_colors_free ()
voidgdk_colors_free (GdkColormap *colormap,
gulong *pixels,gint npixels,gulong planes); 

　　Free colors allocated with gdk_colors_alloc(). This function is obsolete. See gdk_colormap_free_colors().

　　colormap : a GdkColormap.

　　pixels : the pixel values of the colors to free.

　　npixels : the number of values in pixels.

　　planes : the plane masks for all planes to free, OR'd together.

gdk_color_white ()
gbooleangdk_color_white (GdkColormap *colormap,GdkColor *color); 

　　Return the white color for a given colormap. The resulting value has already allocated been allocated.

　　colormap : a GdkColormap.

　　color : the location to store the color.

　　Returns : TRUE if the allocation succeeded.

gdk_color_black ()
gbooleangdk_color_black (GdkColormap *colormap,GdkColor *color); 

　　Return the black color for a given colormap. The resulting value has already benn allocated.

　　colormap : a GdkColormap.

　　color : the location to store the color.

　　Returns : TRUE if the allocation succeeded.

gdk_color_parse ()
gbooleangdk_color_parse (const gchar *spec,GdkColor *color); 

　　Parse a textual specification of a color and fill in the red, green, and blue fields of a GdkColor structure. The color is not allocated, you must call gdk_colormap_alloc_color() yourself. The text string can be in any of the forms accepted by XParseColor; these include name for a color from rgb.txt, such as DarkSlateGray, or a hex specification such as 305050.

　　spec : the string specifying the color.

　　color : the GdkColor to fill in

　　Returns :

gdk_color_alloc ()
gbooleangdk_color_alloc (GdkColormap *colormap,GdkColor *color); 

　　Allocate a single color from a colormap. This function is obsolete. See gdk_colormap_alloc_color().

　　colormap : a GdkColormap.

　　color : The color to allocate. On return, the pixel field will be filled in.

　　Returns : TRUE if the allocation succeeded.
