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. |

Example
This is an example for LAnnStamp::SetBitmap(pBitmap, uFlags=0), with pBitmap of type pBITMAPHANDLE:
L_INT LAnnStamp_SetBitmapExample(HWND hWnd, pBITMAPHANDLE pBitmap, LAnnContainer * pAnnContainer, LAnnStamp * pAnnStamp) { L_INT nRet; HDC hWindowDC; /* Device context of the current window */ ANNRECT ContainerRect; /* Root container's rectangle */ ANNRECT MyStampRect; /* Rectangle for the stamp object */ RECT rAnnBounds; /* Bounding rectangle used to draw the object */ /* Get the device context of the current window */ hWindowDC = GetDC (hWnd); /* Get the container's rectangle */ nRet = pAnnContainer->GetRect(&ContainerRect); if(nRet != SUCCESS) return nRet; /* Size and position the stamp, adjusting the height to keep the bitmap's aspect ratio */ MyStampRect.left = ContainerRect.right / 8; MyStampRect.top = ContainerRect.bottom / 2; MyStampRect.right = ContainerRect.right / 2; MyStampRect.bottom = MyStampRect.top + (((MyStampRect.right - MyStampRect.left) * BITMAPHEIGHT(pBitmap)) / BITMAPWIDTH(pBitmap)); nRet = pAnnStamp->SetRect(&MyStampRect); if(nRet != SUCCESS) return nRet; /* Assign the bitmap to the stamp;*/ nRet = pAnnStamp->SetBitmap(pBitmap,0); if(nRet != SUCCESS) return nRet; /* Display the stamp */ nRet = pAnnStamp->GetBoundingRect(&rAnnBounds); if(nRet != SUCCESS) return nRet; nRet = pAnnStamp->Draw(hWindowDC, &rAnnBounds); if(nRet != SUCCESS) return nRet; ReleaseDC(hWnd, hWindowDC); /* Remove the queued paint message */ ValidateRect(hWnd, &rAnnBounds); return SUCCESS; }
