ScaledPixmapBodyC(const Vector2dC & nscale,const ImageRectangleC & rawImgSize)

Default constructor.

~ScaledPixmapBodyC()

Destructor.

int & Refs()

Refrences.
Used for EXTERNAL bookkeeping.

GdkPixmap * Pixmap()

Access pixmap.

ImageRectangleC DrawToPixmap(GdkDrawable * drawable,const ImageRectangleC & rect,GdkGC * gctxt,PixelC offset = PixelC(0,0))

Do actual drawing to pixmap.
'rect' is in pixmap co-oridinates. Returns area actual updated, which will definitly include 'rect'.

BooleanT CheckRendered(ImageRectangleC rect,GdkGC * gctxt)

Check area has been rendered to pixmap.
'rect' is in pixmap co-oridinates.

BooleanT Draw(ImageRectangleC rect,PixelC pos,GdkGC * gctxt,GdkWindow * win)

Draw rectangle 'rect' from image into 'win' at position 'pos' in window.
'rect' is in pixmap co-oridinates. 'pos' is in display co-oridinates.

void AddReference()

Another reference to the object has been created.

void RemoveReference()

One reference to the object was deleted.
Locking scheme -------------- The object is possible to lock (to make constant). The scheme assumes that the object is created, it can be locked, after that it can only be destroyed. The locked object cannot be unlocked. This locking scheme is very useful during debugging, using assert() function, when it is necassary to check that object is treated as constant and the constancy is not violated by any casting or passing through the copy constructor of shared objects.

void SetConst(void) const

This locks the object.
Often objects you wish to lock are already const.

void SetConst(void)

This locks the object.

BooleanT IsConst(void) const

Returns TRUE if the object is locked, ie. it is assumed to be constant.

BooleanT IsNotConst(void) const

Returns TRUE if the object is unlocked.
ie. there is no special information if the object is constant or not. Counter state information -------------------------

BooleanT ToBeDeleted() const

Returns TRUE if there is only one reference to the object and the whole object or its reference counting part can be deleted.

BooleanT ToBeDeletedRemoveIgnoreNoRemove()

Decrement refrence by 1 return true if this leaves no refrences to the object.

BooleanT ToBeDeletedRemove()

Decrement refrence by 1 return true if this leaves no refrences to the object. This also checks the NoRemove flag.

BooleanT BodyMightBeDeleted() const

Returns TRUE if the reference counted part of the object can be deleted, ie. flag NOREMOVE is false .

BooleanT IsCountZero() const

Are there any refrences left ?

BooleanT BRCPtrCanDeleteObject() const

Used by BRRCPtrC to establish if an object has ZERO refrences and can be deleted.

IntT Count() const

Returns the current state of the counter, ie. how many references to this object exist.

const BodyRefCounterC & operator=(const BodyRefCounterC & b)

It has not meaning to assign object 'b' to this object because it would destroy a history of the object which is counted. So this is a dummy function.

BooleanT IsValidObject() const

Test if object is valid.
When amma check is disabled this always returns true.

BooleanT UserBitTest(IntT x) const

Test user flag.

void UserBitSet(IntT x,BooleanT setit = TRUE)

Test user flag.

void UserBitZero(IntT x)

Set bit to zero.

void ReportBRCError(char * Msg)

Report error, used in BRCPtrC.

UIntT Hash() const

Hash on address of object.

LabelT Label() const

Returns the label of this reference counter.
The member function is useful mainly to recognize objects during debugging. The value of the label is uniquely defined pointer.
