VECTOR_ANTIALIASING

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

Members

L_UINT 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.

L_UINT 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.

L_UINT uFilter

Flag that indicates the type of anti-aliasing filter to use. Possible values are:

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.

The VECTOR_ANTIALIASING structure is used with the VECTOR_DISPLAY_OPTIONS structure.
