Colormap

Object Hierarchy:

public class Colormap : Object

Namespace: Gdk

Package: gdk-2.0

public static weak Colormap get_system ()
Gets the system's default colormap for the default screen. (See gdk_colormap_get_system_for_screen)

public Colormap (Visual visual, bool allocate)
Creates a new colormap for the given visual.

public bool alloc_color (Color color, bool writeable, bool best_match)
Allocates a single color from a colormap.
public int alloc_colors (Color[] colors, bool writeable, bool best_match, bool success)
Allocates colors from a colormap.
public void change (int ncolors)
Changes the value of the first ncolors in a private colormap to match the values in the colors array in the colormap. This function is obsolete and should not be used. See gdk_color_change.
public void free_colors (Color[] colors)
Frees previously allocated colors.
public weak Screen get_screen ()
Gets the screen for which this colormap was created.
public weak Visual get_visual ()
Returns the visual for which a given colormap was created.
public void query_color (ulong pixel, out Color _result)
Locates the RGB color in colormap corresponding to the given hardware pixel pixel. pixel must be a valid pixel in the colormap; it's a programmer error to call this function with a pixel which is not in the colormap. Hardware pixels are normally obtained from alloc_colors , or from a Image. (A Image contains image data in hardware format, a Pixbuf contains image data in a canonical 24-bit RGB format.)
