This class defined the geomtrical reference frame of an
AAM. Hence, it is the spatial layout where all texture
sampling takes place.
The main objective of this class is to provide fast
conversions from a shape-free image to a texture vector
and vice versa.
bool UseConvexHull() const
- Returns true of the convex hull determines the shape extent
- const CAAMShape& RefShape() const
- Returns the reference shape
- int NTextureSamples() const
- Returns the number of texture samples in the texture model
- const CAAMMesh& RefMesh() const
- Returns the reference mesh
- const CDMultiBand<TAAMPixel> & MaskImage() const
- Returns the mask image
- CAAMReferenceFrame()

- void Setup( const CAAMShape &referenceShape, const bool useConvexHull )
-
Sets up the class with the reference shape
and information about how to determine the extent
of the shape.
- Parameters:
- referenceShape - The reference shape.
useConvexHull - If true the convex hull of the reference
shape is used to determine its extent.
- Returns:
- Nothing.

- void ToFile( FILE* fh ) const
-
This method writes the class data to disk. Actually it is
only the reference shape and the convex hull option that
is written. The rest is reconstructed during read.
- Parameters:
- fh - Open file handle to a binary file.
- Returns:
- Nothing.

- void FromFile( FILE* fh )
-
This method reads the class data from disk. Actually it is
only the reference shape and the convex hull option that
is read. The rest is reconstructed.
- Parameters:
- fh - Open file handle to a binary file.
- Returns:
- Nothing.

- void DebugDump()
-
This method writes the reference shape, the mask image
and a test of the Image2Vector() and Vector2image() to
the current directory.
- Returns:
- Nothing.

- ~CAAMReferenceFrame()
-
Destructor. Deletes any reference shape, mesh and mask image.
- Returns:
- Nothing.

- void CalcMaskImage( const bool useConvexHull )
-
This method calculates a reference mask image, where the
shape area is set to 255 and the background to zero.
The resulting image is stored in 'm_pMaskImage'.
- Parameters:
- useConvexHull - If true the convex hull is used to define
the extent of the reference shape.
- Returns:
- Nothing.

- Version:

- void CalcScanLines()
-
This method calculates the scanlines of the mask image.
A scanline is a subpart of a horsontal image line that
is occupied but a subpart of the reference shape.
The resulting scanlines are used for quick'n'easy conversion
from spatial to vector layout (and back).
Scanlines are stored in 'm_ScanlineParts'.
- Returns:
- Nothing.
