The SATURATIONDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogColor::DoModalSaturation function. After the user closes the dialog box, information about the user's selections are updated in this structure.
typedef struct _SATURATIONDLGPARAMS{L_UINT uStructSize;pBITMAPHANDLE pBitmap;L_BOOL bZoomToFit;L_INT nChange;L_UINT32 uDlgFlags;LTCOMMDLGHELPCB pfnHelpCallback;L_VOID *pHelpCallBackUserData;} SATURATIONDLGPARAMS, * LPSATURATIONDLGPARAMS;
Size of this structure, in bytes. Use the sizeof operator to calculate this value.
