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.
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.
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.
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. |
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 L_AntiAliasBitmap. For more information about using L_AntiAliasBitmap, please refer to the LEADTOOLS Raster C API Help File.
The VECTOR_ANTIALIASING structure is used with the VECTOR_DISPLAY_OPTIONS structure.
