LAnnPoint::SetBitmap

#include "ltwrappr.h"

virtual L_INT LAnnPoint::SetBitmap(pBitmap, uFlags=0)

Sets the bitmap of the annotation object.

Parameters

LBitmapBase * pBitmap

Pointer to the bitmap object referencing the bitmap object to assign to the specified object.

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle referencing the bitmap to assign to the specified object.

L_UINT uFlags

Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR (|). The following are valid values:

Value	Meaning
0	Process only the specified object.
ANNFLAG_SELECTED	[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions.
ANNFLAG_NOINVALIDATE	[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Example

This is an example for both forms of LAnnPoint::SetBitmap(pBitmap, uFlags=0):

L_INT LAnnPoint_SetBitmapExample(HWND hWnd) 
{ 
   ANNPOINT annPoint = {50,50}; 
   ANNRECT  annRect =  {50,50,150,150}; 
 
   LAnnPoint *pMyAnnPoint = new(LAnnPoint); 
 
   pMyAnnPoint->SetPoints(&annPoint); 
   pMyAnnPoint->SetVisible(TRUE); 
 
   //Change LAnnPoint bitmap 
   LBitmapBase MyBitmapBasePrimary; 
   MyBitmapBasePrimary.Load(MAKE_IMAGE_PATH(TEXT("image1.cmp"))); 
   pMyAnnPoint->SetBitmap (&MyBitmapBasePrimary,0); 
 
   //Another way to change the bitmap 
   pMyAnnPoint->SetBitmap(MyBitmapBasePrimary.GetHandle(),0); 
 
   //Create container and insert annotation 
   LAnnContainer m_AnnContainer;  
   m_AnnContainer.Create(hWnd, &annRect, TRUE); 
   m_AnnContainer.Insert(*pMyAnnPoint); 
   m_AnnContainer.SetUserMode(ANNUSER_RUN); 
 
   return SUCCESS; 
}
