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. |
SUCCESS |
The function was successful. |
< 1 |

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;
