Re: Enhanced metafile increases when being played.

Hello,

I'm struggling with enhanced metafiles.
What I have is an enhanced metafile on disk, where I want to modify a
comment.

Here is how I try to do this (simplified):
HENHMETAFILE hMetaFile = GetEnhMetaFile(TmpFileName);
HDC hTargetDC = CreateEnhMetaFile(DC.m_hDC, NULL, &Bounds,
_T("WinHCU\0tmp\0\0"));
EnumEnhMetaFile(hTargetDC, hMetaFile, ProtoView_EnhMetaFileReplaceProc,
NULL, &ZeichenRect);
DeleteEnhMetaFile(hMetaFile);
hMetaFile = CloseEnhMetaFile(hTargetDC);
CopyEnhMetaFile(hMetaFile, TmpFileName2);
CloseHandle(hMetaFile);

My Callback function looks like this:
int CALLBACK ProtoView_EnhMetaFileReplaceProc(
  __in HDC hDC,
  __in HANDLETABLE * lpHTable,
  __in const ENHMETARECORD *lpEMFR,
  __in int nObj,
  __in LPARAM lpData
)
{
 return PlayEnhMetaFileRecord(hDC, lpHTable, lpEMFR, nObj);
}

It's no problem for me to identify and modify the comment in the metafile.
The problem is that the metafile increases from 6 records to 29 records
even if I don't modify anything.
If I do this over and over again the number of records seems to double
every time.
The same result for PlayEnhMetaFile instead of EnumEnhMetaFile.

So how can I play one metafile into a new one without increasing the
number of records?

Please see the attached two files for an example. bild1.emf is the
original, bild2.emf is the increased file.

TIA
