#include "ltwrappr.h"

LBitmapRgn::LBitmapRgn()

LBitmapRgn::LBitmapRgn(pLBitmap, uCombineMode = L_RGN_SET)

LBitmapBase * pLBitmap;	pointer to the LBitmapBase object
L_UINT uCombineMode;	flag that indicates the action to take with the bitmap region

Constructs an LBitmapRgn object.

Parameter	Description
pLBitmap	Pointer to the LBitmapBase object to be associated with the new LBitmapRgn object. All region functions will operate on the LBitmapBase object's bitmap.
uCombineMode	Flag that indicates the action to take with the bitmap region. For a list of possible values refer to Creating a Bitmap Region.

Returns

None

Comments

LBitmapRgn::LBitmapRgn(void) constructs an LBitmapRgn object.

LBitmapRgn::LBitmapRgn(pLBitmap, uCombineMode = L_RGN_SET) constructs an LBitmapRgn object and initializes it with the specified LBitmapBase object's bitmap and region, if one is defined. The uCombineMode parameter becomes the class object's region combine mode for any functions that set a region.

Example

This is an example for LBitmapRgn::LBitmapRgn(void):

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT LBitmapRgn__LBitmapRgnFirstExample() 
{ 
   // this will call the default constructor and destructor when it is out of scope 
   LBitmapRgn MyRgn; 
   //… 
   return SUCCESS; 
} 
//This is an example for LBitmapRgn::LBitmapRgn(pLBitmap, uCombineMode): 
L_INT LBitmapRgn__LBitmapRgnSecondExample() 
{ 
   L_INT nRet; 
   LBitmapBase    LeadBitmap; 
   LBitmapRgn     *pMyRgn; 
   nRet =LeadBitmap.Load(MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image3.cmp")), 8, ORDER_BGR); 
   if(nRet !=SUCCESS) 
      return nRet; 
   pMyRgn = new LBitmapRgn(&LeadBitmap,L_RGN_ANDNOTBITMAP); 
   // do process here 
   // ... 
   // call destructor for LBitmapRgn 
   delete pMyRgn ; 
   //… 
   return SUCCESS; 
}
