QuestionCreating .ico file from HICON Pin
neilsolent11-Jan-07 2:22
Memberneilsolent11-Jan-07 2:22 
In a previous post I was attempting to "serialize" an HICON, i.e. save it as a blob in a file or database: the opposite operation to the ExtractIcon() operation. I have since learned how to do this (see routine below).

BUT now my problem is, this routine loses color information. When the routine is run against a true-color icon, and the buffer is saved as a .ico file, and the .ico file is reloaded with ExtractIcon(), the resulting icon has reduced to 256 colors.

I think this must be a limitation of OleCreatePictureIndirect(). How can I fix my routine?

------------------------------------------------

void SerializeIcon(const HICON icon, DWORD* size, BYTE** data)
{
LPPICTURE pPicture;
PICTDESC rPD;
rPD.cbSizeofstruct = sizeof(PICTDESC);
rPD.picType = PICTYPE_ICON;
rPD.icon.hicon = icon;
IStream* pStream = NULL;
HGLOBAL hMem = NULL;
BYTE* pMem = NULL;
long lActual;

OleCreatePictureIndirect(&rPD, IID_IPicture, FALSE, (void**) &pPicture);
CreateStreamOnHGlobal(0, TRUE, &pStream);
pPicture->SaveAsFile(pStream, TRUE, &lActual);
pPicture->Release();
GetHGlobalFromStream(pStream, &hMem);
pMem = (BYTE*) GlobalLock(hMem);
*size = GlobalSize(hMem);
*data = (BYTE*) malloc(*size);
CopyMemory(*data, pMem, *size);
GlobalUnlock(hMem);
GlobalFree(hMem);
}
