= class Gdk::Pixmap
Pixmaps are offscreen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a Gdk::Window) with Gdk::Drawable#draw_drawable. The depth of a pixmap is the number of bits per pixels. Bitmaps are simply pixmaps with a depth of 1. (That is, they are monochrome bitmaps - each pixel can be either on or off).

== Class Methods
--- Gdk::Pixmap.new(window, width, height, depth)
Create a new pixmap with a given size and depth.
* window: a Gdk::Window, used to determine default values for the new pixmap. Can be nil if depth is specified.
* width: The width of the new pixmap in pixels.
* height: The height of the new pixmap in pixels.
* depth: The depth (number of bits per pixel) of the new pixmap. If -1, and window is not nil, the depth of the new pixmap will be equal to that of window.
* Returns: the new Gdk::Pixmap
--- Gdk::Pixmap.create_from_data(window, data, width, height, depth = nil, fg = nil, bg = nil)
Creates a new pixmap/bitmap(depth=nil) from data in XBM format.
* window: a Gdk::Window, used to determine default values for the new pixmap. Can be nil, in which case the root window is used.
* data: a String containing the XBM data.
* width: the width of the new pixmap in pixels.
* height: the height of the new pixmap in pixels.
* depth: the depth (number of bits per pixel) of the new pixmap, or nil for the bitmap.
* fg: the foreground color(Gdk::Color), or nil for the bitmap.
* bg: the background color(Gdk::Color), or nil for the bitmap.
* Returns : the new Gdk::Pixmap
--- Gdk::Pixmap.create_from_xpm(window, transparent_color, filename)
Create a pixmap from a XPM file.
* window: a Gdk::Window, used to determine default values for the new pixmap.
* transparent_color: the Gdk::Color to be used for the pixels that are transparent in the input file. Can be nil, in which case a default color will be used.
* filename: the filename of a file containing XPM data.
* Returns: [pixmap, mask]
* pixmap: a new Gdk::Pixmap
* mask: a new Gdk::Pixmap of a bitmap representing the transparency mask of the XPM file.
--- Gdk::Pixmap.colormap_create_from_xpm(window, colormap, transparent_color, filename)
Create a pixmap from a XPM file using a particular colormap.
* window: a Gdk::Window, used to determine default values for the new pixmap. Can be nil if colormap is given.
* colormap: the Gdk::Colormap that the new pixmap will be use. If nil, the colormap for window will be used.
* transparent_color: the color to be used for the pixels that are transparent in the input file. Can be nil, in which case a default color will be used.
* filename: the filename of a file containing XPM data.
* Returns: [pixmap, mask]
* pixmap: a new Gdk::Pixmap
* mask: a new Gdk::Pixmap of a bitmap representing the transparency mask of the XPM file.
--- Gdk::Pixmap.create_from_xpm_d(window, transparent_color, data)
Create a pixmap from data in XPM format.
* window: a Gdk::Window, used to determine default values for the new pixmap.
* transparent_color: This color will be used for the pixels that are transparent in the input file. Can be nil in which case a default color will be used.
* data: a String containing the XPM data.
* Returns: [pixmap, mask]
* pixmap: a new Gdk::Pixmap
* mask: a new Gdk::Pixmap of a bitmap representing the transparency mask of the XPM file.
--- Gdk::Pixmap.colormap_create_from_xpm_d(window, colormap, transparent_color, data)
Create a pixmap from data in XPM format using a particular colormap.
* window: a Gdk::Window, used to determine default values for the new pixmap. Can be nil if colormap is given.
* colormap: the Gdk::Colormap that the new pixmap will be use. If nil, the colormap for window will be used.
* transparent_color: the color to be used for the pixels that are transparent in the input file. Can be nil, in which case a default color will be used.
* Returns: [pixmap, mask]
* pixmap: a new Gdk::Pixmap
* mask: a new Gdk::Pixmap of a bitmap representing the transparency mask of the XPM file.
--- Gdk::Pixmap.create_from_xbm(window, filename)
Create a pixmap from data in XBM format. ((* X11 version only *))
* window: a Gdk::Window, used to determine default values for the new pixmap. Can be nil, in which case the root window is used.
* filename: the filename of a file containing XBM data.
* Returns: a new Gdk::Pixmap
--- gl_capable?
((*Ruby/GtkGlExt*)) Returns whether the pixmap is OpenGL-capable.
* Returns: true if the pixmap is OpenGL-capable, false otherwise.
--- gl_drawable
((*Ruby/GtkGlExt*)) Returns the Gdk::GLDrawable held by the pixmap. In fact, this is a macro that casts the result of Gdk::Pixmap#gl_pixmap to Gdk::GLDrawable.
* Returns: the Gdk::GLDrawable.
--- gl_pixmap
((*Ruby/GtkGlExt*)) Returns the Gdk::GLPixmap held by the pixmap.
* Returns: the Gdk::GLPixmap.
--- set_gl_capability(glconfig)
((*Ruby/GtkGlExt*)) Set the OpenGL-capability to the pixmap. This function creates a new Gdk::GLPixmap held by the pixmap.
* glconfig: a Gdk::GLConfig.
* Returns: the Gdk::GLPixmap used by the pixmap if it is successful, nil otherwise.
--- unset_gl_capability
((*Ruby/GtkGlExt*)) Unset the OpenGL-capability of the pixmap. This function destroys the Gdk::GLPixmap held by the pixmap.
* Returns: self
