-// TXImage.h

-// A TXImage represents a rectangular off-screen image in any RFB pixel format.
-// By default it will use the "native" pixel format for the screen, which will
-// be an 8-bit colourmap unless the X display is TrueColor. The pixel format
-// can be changed via the setPF() method. The pixel data is accessible via the
-// data member inherited from FullFramePixelBuffer, or can be set via the
-// fillRect(), imageRect(), copyRect() and maskRect() methods, also inherited
-// from PixelBuffer. A rectangle of the image can be drawn into an X Window
-// via the put() method. If using a colourmap, the setColourMapEntries() and
-// updateColourMap() methods must be called to set up the colourmap as
-// appropriate.
