+	@title:
+		pixmap class
+	@type:
+		class
+	@short:
+		This class provide a pixmap.
+	@inherits:
+		[class]object[/class]
+		[class]widget[/class]
+	@description:
+		The pixmap class is an off-screen, pixel-based paint device.		
+	@functions:
+		!fn: $fill(<widget:object>,<x_offset:integer>,<y:offset>)
+		Fills the pixmap with the widget's background color or pixmap.[br]
+		Note that x_offset, y_offest are offsets in the widget.
+		!fn: $resize(<width:integer>,<height:integer>)
+		Resizes the pixmap to w width and h height. Set wh or hg to 0, to have a null pixmap.
+		!fn: $scale(<sx:real>,<sy:real>)
+		Scales the pixmap by sx horizontally and sy vertically.
+		!fn: $rotate(<a:real>)
+		Rotates the pixmap by a degrees.
+		!fn: $load(<file_name:string>)
+		Load a pixmap from the <file>.
+		!fn: <integer> $height()
+		Return the height of the pixmap.
+		!fn: <integer> $width()
+		Return the width of the pixmap.
