LAnnPoint::SetBitmap

#include "ltwrappr.h"

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

LBitmapBase * pBitmap;	/* pointer to an LBitmapBase object */
pBITMAPHANDLE pBitmap;	/* pointer to the bitmap handle */
L_UINT uFlags;	/* flags that determine the object to process */

Sets the bitmap of the annotation object.

Parameter	Description
pBitmap	Pointer to the bitmap object referencing the bitmap object to assign to the specified object.
pBitmap	Pointer to the bitmap handle referencing the bitmap to assign to the specified object.
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

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):

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName
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;
