POINTSPREADFUNCTION (original) (raw)

Summary

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

Syntax

typedef struct _POINTSPREADFUNCTION { [L_UINT](leadtools-basic-data-types.html) uStructSize; [L_UINT](leadtools-basic-data-types.html) nHeight; [L_UINT](leadtools-basic-data-types.html) nWidth; [L_DOUBLE](leadtools-basic-data-types.html)* pValues; } POINTSPREADFUNCTION, *pPOINTSPREADFUNCTION;

Members

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.

Comments

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.

Usage

• L_BitmapWienerFilter
• L_CreatePreDefinedFilter
• L_FreePredefinedFilter
