dimension values = 0

Constructor for image objects: use this for scaled images.
Dimensions are defined with parameters w (width) and h (height).
Note: only dimension values >0 causes scaling of image!
Note: See also class CComponentsPictureScalable(). That does the same like this, but uses internal value 0 for parameters w (width) and h (height).
If scaling is not required, you should use overloaded version that comes without dimension parameters.
If no dimensions are defined (in constructor or e.g. with setWidth() or setHeight(),
width and height are defined by image itself and are retrievable e.g. with getWidth() or getHeight().

Constructor for image objects, use this for non scaled images. This is similar with known method paintIcon() from framebuffer class.
Dimensions are defined by image itself.
Note: you can use the dimension setters setWidth() or setHeight() too, but this has only effects for item body, not for image!

class CComponentsPictureScalable().
