Panic due to CFbsBitmap loaded in Font and bitmap server

Thanks for that info - it's definately something I will bear in mind when using CFbsBitmap.

Figured it out

Actually I took this question right to the top and asked Symbian support here in Japan.
Basically in my case, the deletion of the memory representing the CFbsBitmap object takes place asynchrously, as the CFbsBitmap was large, the cleanup actually took place after the session ended.
I ended up using a client / server architecture and checked the heap using __UHEAP_MARKEND; after the session was closed.

Still having trouble with CFbsBitmap

This problem is quite simple but I am missing something fundamental with how to allow the bitmap server to release the bitmap's associated memory. Even this little snippet of code will Panic.

__UHEAP_MARK;
_LIT(KTestMbm, "Z:\\SYSTEM\\APPS\\HelloWorld\\T_TestBitmap.MBM");
TInt id = 0;
CFbsBitmap* bitty = new (ELeave) CFbsBitmap();

bitty->Load(KTestMbm, 0, EFalse);
bitty->Reset();
delete bitty;
bitty = NULL;
__UHEAP_MARKEND;

At __UHEAP_MARK a Panic occurs. The bitmap itself is deleted but something is still not released from the server. Hmmm. Please help.

Thanks for the reply Elk!

I tried the
TRAP(ret, saveImage.SaveJpegL(KDestJPEGFileError, *this, info ) );
if(ret != KErrNone)
   {
   CleanupStack::PopAndDestroy( bitty ); // Elk's suggestion
   User::Leave( ret );
   }
...

Even with that, the pesky Font and Bitmap server does not release that area of memory taken up at this point in the code.

User::LeaveIfError(bitty->Load( KTestMBM, 0, EFalse));

Once I load the bitmap from the MBM file, I can't seem to release the memory from the server.

Is there something else I can try?

Thanks for the help.

_LIT(KTestMBM, "Z:\\system\\Apps\\T_ItFjmmSaveImageCat1\\T_ItFjmmSaveImage.MBM");
CFbsBitmap* bitty = new (ELeave) CFbsBitmap;
CleanupStack::PushL(bitty);
User::LeaveIfError(bitty->Load( KTestMBM, 0, EFalse));
iEncoder = CImageEncoder::FileNewL( iFs, aFileName, CImageEncoder::EOptionNone, KImageTypeJPGUid ));
...
CleanupStack::PopAndDestroy(bitty); // or just Pop, if you want to keep it around
