LAnnPoint::GetBitmap

#include "ltwrappr.h"

virtual L_INT LAnnPoint::GetBitmap(pBitmap)

virtual L_INT LAnnPoint::GetBitmap(pBitmap, uStructSize)

LBitmapBase * pBitmap;	/* pointer to an LBitmapBase object */
pBITMAPHANDLE pBitmap;	/* address of the variable to be updated */
L_UINT uStructSize;	/* size in bytes, of the structure pointed to by pBitmap */

Gets the bitmap handle of the annotation object.

Parameter	Description
pBitmap	Pointer to an LBitmapBase object to be updated with the handle to the annotation object's bitmap.
pBitmap	Address of the variable to be updated with the handle to the annotation object's bitmap.
uStructSize	Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).

Returns

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

Comments

Before calling LAnnPoint::GetBitmap(pBitmap), where pBitmap is of type LBitmapBase , you must declare aan LBitmapBase object. Then, pass the address of the object in the pBitmap parameter. This function will update the object with the handle to the annotation object's bitmap.

Before calling LAnnPoint::GetBitmap(pBitmap), where pBitmap is of type pBITMAPHANDLE, you must declare a variable of data type BITMAPHANDLE. Then, pass the address of the variable in the pBitmap parameter. This function will update the variable with the handle to the annotation object's bitmap.

Example

This is an example of both forms of LAnnPoint::GetBitmap(pBitmap:

L_INT LAnnPoint_GetBitmapExample(HWND hWnd)
{
   ANNPOINT annPoint = {50,50};
   ANNRECT  annRect =  {50,50,150,150};
   LSettings::UnlockSupport(L_SUPPORT_DOCUMENT, L_KEY_DOCUMENT);
   LAnnPoint *pMyAnnPoint = new(LAnnPoint);
   pMyAnnPoint->SetPoints(&annPoint);
   pMyAnnPoint->SetVisible(TRUE);
   //Invert the primary bitmap
   LBitmapBase *pBitmapBase = new(LBitmapBase);
   pMyAnnPoint->GetBitmap(pBitmapBase, sizeof(BITMAPHANDLE));
   //or
   //BITMAPHANDLE LeadBitmap;
   //pMyAnnPoint->GetBitmap(&LeadBitmap, sizeof(BITMAPHANDLE));
   //Make the annotation point all white
   pBitmapBase->Fill(RGB(255,255,255));
   //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;
