LINEREMOVEDLGPARAMS

Summary

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

Syntax

typedef struct _LINEREMOVEDLGPARAMS 
{ 
   L_UINT uStructSize; 
   pBITMAPHANDLE pBitmap; 
   L_BOOL bZoomToFit; 
   LINEREMOVE LineRemove; 
   COLORREF crModification; 
   L_UINT32 uDlgFlags; 
   LTCOMMDLGHELPCB pfnHelpCallback; 
   L_VOID  *pHelpCallBackUserData; 
} LINEREMOVEDLGPARAMS,  * LPLINEREMOVEDLGPARAMS; 

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:

Value Meaning
TRUE Set the initial zoom level to "Zoom to fit".
FALSE Set the initial zoom level to "Normal (1:1)".

LineRemove

LINEREMOVE structure that LEADTOOLS uses to perform the line removal operation.You should pass valid pBitmapRegion address and fill the uBitmapStructSize with the proper value.

✅ IMPORTANT

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

crModification

Color used to fill the modified 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:

Value Meaning
DLG_LINEREMOVE_AUTOPROCESS [0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid 1-bit bitmap.
DLG_LINEREMOVE_SHOW_CONTEXTHELP [0x00000002] dialog should contain a context sensitive help icon.
DLG_LINEREMOVE_SHOW_PREVIEW [0x00000004] show a preview of the image in the dialog. The pBitmap member of this structure should contain a valid 1-bit bitmap.
DLG_LINEREMOVE_SHOW_TOOL_ZOOMLEVEL [0x00000008] show the "Zoom to fit" and "Zoom Normal" toolbar buttons. The DLG_LINEREMOVE_SHOW_PREVIEW flag must be set in order to show these buttons.

pfnHelpCallback

Ignored.

pHelpCallBackUserData

Ignored.
