Bitmaps and Pixmaps Offscreen drawables Pixmaps are offscreen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a #GdkWindow) with gdk_pixmap_draw(). 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). An opaque structure representing an offscreen drawable. Pointers to structures of type #GdkPixmap, #GdkBitmap, and #GdkWindow, can often be used interchangeably. The type #GdkDrawable refers generically to any of these types. Create a new pixmap with a given size and depth. @drawable: A #GdkDrawable, used to determine default values for the new pixmap. Can be %NULL 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 @drawable is not %NULL, the depth of the new pixmap will be equal to that of @drawable. @Returns: the #GdkPixmap Creates a new bitmap from data in XBM format. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. Can be %NULL, in which case the root window is used. @data: a pointer to the XBM data. @width: the width of the new pixmap in pixels. @height: the height of the new pixmap in pixels. @Returns: the #GdkBitmap Create a two-color pixmap from data in XBM data. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. Can be %NULL, if the depth is given. @data: a pointer to the 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. @fg: the foreground color. @bg: the background color. @Returns: the #GdkPixmap Create a pixmap from a XPM file. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. @mask: a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be %NULL, in which case transparency will be ignored. @transparent_color: the color to be used for the pixels that are transparent in the input file. Can be %NULL, in which case a default color will be used. @filename: the filename of a file containing XPM data. @Returns: the #GdkPixmap Create a pixmap from a XPM file using a particular colormap. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. Can be %NULL if @colormap is given. @colormap: the #GdkColormap that the new pixmap will be use. If omitted, the colormap for @window will be used. @mask: a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be %NULL, in which case transparency will be ignored. @transparent_color: the color to be used for the pixels that are transparent in the input file. Can be %NULL, in which case a default color will be used. @filename: the filename of a file containing XPM data. @Returns: the #GdkPixmap. Create a pixmap from data in XPM format. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. @mask: Pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be %NULL, in which case transparency will be ignored. @transparent_color: This color will be used for the pixels that are transparent in the input file. Can be %NULL in which case a default color will be used. @data: Pointer to a string containing the XPM data. @Returns: the #GdkPixmap Create a pixmap from data in XPM format using a particular colormap. @drawable: a #GdkDrawable, used to determine default values for the new pixmap. Can be %NULL if @colormap is given. @colormap: the #GdkColormap that the new pixmap will be use. If omitted, the colormap for @window will be used. @mask: a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be %NULL, in which case transparency will be ignored. @transparent_color: the color to be used for the pixels that are transparent in the input file. Can be %NULL, in which case a default color will be used. @data: Pointer to a string containing the XPM data. @Returns: the #GdkPixmap. Deprecated equivalent of g_object_ref(). @Returns: @pixmap Deprecated equivalent of g_object_unref(). An opaque structure representing an offscreen drawable of depth 1. Pointers to structures of type #GdkPixmap, #GdkBitmap, and #GdkWindow, can often be used interchangeably. The type #GdkDrawable refers generically to any of these types. @user_data: Deprecated equivalent of g_object_ref(). @Returns: @pixmap Deprecated equivalent of g_object_unref().
