LAnnPoint::GetPredefinedBitmap

#include "ltwrappr.h"

static L_INT LAnnPoint::GetPredefinedBitmap(uType, pBitmap, uStructSize)

static L_INT LAnnPoint::GetPredefinedBitmap(uType, pLBitmap, uStructSize)

L_UINT uType;

constant that indicates the bitmap to retrieve

pBITMAPHANDLE pBitmap;

pointer to a variable to be updated with the bitmap handle

pLBitmapBase *pLBitmap;

pointer to an object to be updated with the bitmap handle

L_UINT uStructSize;

size in bytes, of the structure pointed to by pBitmap or pLBitmap

Retrieves a copy of the specified predefined bitmap.

Parameter Description
uType Value that indicates the bitmap to retrieve.  Possible values are:
  Value Meaning
  ANNBITMAP_POINT [0] Predefined metafile for annotation point object
pBitmap Pointer to a variable to be updated with the bitmap handle.
pLBitmap Pointer to a valid bitmap object containing the image to set.
uStructSize Size in bytes, of the structure pointed to by pBitmap or pLBitmap.. Use sizeof(BITMAPHANDLE).

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

You must free the bitmap handle when you are finished, using the LBitmapBase::Free function. Call the LAnnPoint::SetPredefinedBitmap function to change or reset the predefined bitmap.

Example

// This example does the following: // 1. Gets the current point bitmap // 2. Inverts it // 3. Sets the inverted bitmap as the default point bitmap 

L_INT LAnnPoint_GetPredefinedBitmapExample() 
{ 
	L_INT nRet; 
   LBitmap PointBitmap;  
 
   // Get predefined point bitmap 
   nRet = LAnnPoint::GetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap, sizeof(BITMAPHANDLE));  
	if(nRet != SUCCESS) 
		return nRet; 
 
   // Invert it 
   nRet = PointBitmap.Invert(); 
	if(nRet != SUCCESS) 
		return nRet; 
 
   // Set as new point bitmap 
   nRet = LAnnPoint::SetPredefinedBitmap (ANNBITMAP_POINT, &PointBitmap);  
	if(nRet != SUCCESS) 
		return nRet; 
   MessageBox(NULL, TEXT("Now create a point annotation object.  The bitmap is inverted"), TEXT(""), MB_OK);  
	 
	return SUCCESS; 
}
