EROSIONFILTERDLGPARAMS

Summary

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

Syntax

typedef struct _EROSIONFILTERDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   pBINARYFLT pFilter; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} EROSIONFILTERDLGPARAMS,  * LPEROSIONFILTERDLGPARAMS; 

Members

uStructSize

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

pBitmap

Ignored.

bZoomToFit

• BFLT_EROSION_HORZ
• BFLT_EROSION_VERT
• BFLT_EROSION_DIAG

uDlgFlags

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

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
