VECTOR_ANTIALIASING

typedef struct _VECTOR_ANTIALIASING 
{ 
   L_UINT uThreshold; 
   L_UINT uDim; 
   L_UINT uFilter; 
}VECTOR_ANTIALIASING, *pVECTOR_ANTIALIASING;

The VECTOR_ANTIALIASING structure is used in the vector display options to apply the anti-aliasing effect to the vector image being displayed.

Member Description
uThreshold Threshold value that indicates which pixels to smooth. The application of the anti-aliasing filter on the image associates a value with each pixel. Only pixels with values above this threshold are smoothed.
uDim Value that indicates the size of the anti-aliasing mask. For example, a value of three indicates an anti-aliasing mask of 3 X 3.
uFilter Flag that indicates the type of anti-aliasing filter to use. Possible values are:
  Value Meaning
  ANTIALIAS_1 [0x0000] Anti-alias the bitmap vertically and horizontally.
  ANTIALIAS_2 [0x0001] Anti-alias the bitmap in all directions.
  ANTIALIAS_3 [0x0002] Anti-alias the bitmap in all directions. The filter used for this option is different from the filter used for the ANTIALIAS_2 option.
  ANTIALIAS_DIAG [0x0003] Anti-alias the bitmap diagonally.
  ANTIALIAS_HORZ [0x0004] Anti-alias the bitmap horizontally.
  ANTIALIAS_VERT [0x0005] Anti-alias the bitmap vertically.

Comments

pVECTOR_ANTIALIASING is a pointer to a VECTOR_ANTIALIASING structure. Where the function parameter type is pVECTOR_ANTIALIASING, you can declare a VECTOR_ANTIALIASING variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pVECTOR_ANTIALIASING variable is necessary only if your program requires a pointer.

This structure uses the data members the same way as the function LBitmap::AntiAlias. For more information about using LBitmap::AntiAlias, please refer to the LEADTOOLS Raster C++ Class Library Help File, Ltclibn.chm.

The VECTOR_ANTIALIASING structure is used with the VECTOR_DISPLAY_OPTIONS structure.
