SMOOTHDLGPARAMS

Summary

The SMOOTHDLGPARAMS structure provides information used to initialize the dialog box created by the LDialogDocument::DoModalSmooth function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Syntax

typedef struct _SMOOTHDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   SMOOTH Smooth; 
   COLORREF crWhiteArea; 
   COLORREF crBlackArea; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} SMOOTHDLGPARAMS,  * LPSMOOTHDLGPARAMS; 

Members

uStructSize

Size of this structure, in bytes. Use the sizeof operator to calculate this value.

pBitmap

Pointer to the bitmap handle that references the 1-bit bitmap used for preview or processing.

bZoomToFit

Flag that indicates the initial zoom level for previewing the image. Possible values are:

Smooth

A SMOOTH structure that LEADTOOLS uses to perform the smoothing operation. You should pass valid pBitmapRegion address and fill the uBitmapStructSize with the proper value.

✎ NOTE

It is the user's responsibility to free the region in pBitmapRegion, if there is one, using LBitmapRgn::Free.

crWhiteArea

Color used to fill the smoothed white areas. This is used only for dialog previewing purposes. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.

crBlackArea

Color used to fill the smoothed black areas. This is used only for dialog previewing purposes. You can specify a COLORREF value, such as the return value of the Windows RGB macro, or you can use the PALETTEINDEX macro to specify a palette color.

uDlgFlags

User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.

Usage

• LDialogDocument::GetSmoothParams
• LDialogDocument::SetSmoothParams
