The POINTSPREADFUNCTION structure contains the point spread function that will be used when applying a Wiener filter to an image.

Member Description
uStructSize Size of this structure in bytes, for versioning. Use the sizeof() operator to calculate this value.
nHeight The height of the point spread function.
nWidth The width of the point spread function.
pValues An array of double values that represents the values of the point spread function.


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

This structure is used by the L_BitmapWienerFilter and L_CreatePreDefinedFilter functions.
