DOTREMOVEDLGPARAMS

Summary

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

Syntax

typedef struct _DOTREMOVEDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   DOTREMOVE DotRemove; 
   COLORREF crWhiteArea; 
   COLORREF crBlackArea; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} DOTREMOVEDLGPARAMS,  * LPDOTREMOVEDLGPARAMS; 

Members

uStructSize

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

pBitmap

Ignored.

bZoomToFit

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

DotRemove

DOTREMOVE structure that LEADTOOLS uses to remove dots. You should set the pBitmapRegion member of the DOTREMOVE structure to a valid address and fill the uBitmapStructSize member 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 removed 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 removed 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.
