Inheritance diagram for WNT_ImageManager:

Public Member Functions
	WNT_ImageManager (const WNT_WindowPtr &aWindow)
	Creates a class instance
virtual void	Destroy ()
	Deletes all resources associated with the class instance.
	~WNT_ImageManager ()
void	SetFormat (const WNT_TypeOfImage aFormat=WNT_TOI_XWD)
	Sets image format for output.
void	Add (const Handle< WNT_Image > &anImage)
	Adds <anImage> to manager.
Handle_WNT_Image	Image (const Standard_Integer anIndex)
	returns Image stored at <anIndex>.
Standard_Integer	Load (const Standard_CString aFileName)
	Loads image from file and returns its index in the sequence. Warning: Returns 0 if loading was failed.
Standard_Boolean	Save (const Standard_CString aFileName, const Standard_Integer aX, const Standard_Integer aY, const Standard_Integer aWidth, const Standard_Integer aHeight) const
	Stories image to the file according to <myFormat> class field. Returns True on success, otherwise returns False.
Standard_Boolean	SaveBuffer (const Standard_CString aFileName, const Standard_Integer aX, const Standard_Integer aY, const Standard_Integer aWidth, const Standard_Integer aHeight) const
	Stories contents of the double buffer window pixmap. See "Save" method.
void	Draw (const Standard_Integer anIndex, const Standard_Integer Xc, const Standard_Integer Yc, const Standard_Integer aWidth, const Standard_Integer aHeight, const Standard_Real anAngle=0.0)
	Displays the image according to the DoubleBuffer state of the associated window.
void	Delete (const Standard_Integer anIndex)
	Deletes an image at index <anIndex>.
void	Discard (const Standard_Integer anIndex)
	Places an image to the trash
Aspect_Handle	Scale (const Standard_Integer anIndex, const Standard_Real aScaleX, const Standard_Real aScaleY, const Standard_Boolean aReplace=Standard_False)
	Scales the specified image.
Standard_Integer	Size () const
	Returns number of loaded images.
Aspect_Handle	ImageHandle (const Standard_Integer anIndex)
	Returns image handle.
void	Dim (const Standard_Integer anIndex, Standard_Integer &aWidth, Standard_Integer &aHeight)
	Returns image dimensions.
Standard_Integer	HashCode (const Standard_Integer anIndex)
	Returns image's hash code.
Standard_Integer	Index (const Standard_Integer aHashCode)
	Returns image's index.
Standard_Integer	StringHashCode (const Standard_CString aString)
	Returns hash code of the string.
Standard_Integer	Open (const Aspect_Handle aDC, const Standard_Integer aWidth, const Standard_Integer aHeight, const Standard_Integer aHashCode)
	Creates new empty image and returns its index
