请教各位高手：
我想把硬盘上的.gif图片保存到数据字典，然后可以从数据字典中读取数据再还原到硬盘上．
可是.gif如何保存到数据字典？我是用下面的格式保存字符串等信息的，但不知道图片怎么保存，
发现有一个 AcDb::kDxfBinaryChunk类型，字面上是二进制块，不知道是保存什么类型的
AcDbDictionary *pNamedobj, *pDict;
acdbHostApplicationServices()->workingDatabase()
->getNamedObjectsDictionary(pNamedobj, AcDb::kForWrite);
if (pNamedobj->getAt("ASDK_DICT", (AcDbObject*&) pDict,
AcDb::kForWrite) == Acad::eKeyNotFound)
{
pDict = new AcDbDictionary;
AcDbObjectId DictId;
pNamedobj->setAt("ASDK_DICT", pDict, DictId);
}
pNamedobj->close();
// Add a new xrecord to the ASDK_DICT dictionary.
//
AcDbXrecord *pXrec = new AcDbXrecord;
AcDbObjectId xrecObjId;
pDict->setAt("XREC1", pXrec, xrecObjId);
pDict->close();
struct resbuf *pHead;
DWORD flen;
CFile bfile;
CMemFile buffer;
BYTE *psf;
bfile.Open("c:\\abc.gif",CFile::modeReadWrite,NULL);
flen=bfile.GetLength();
psf=(BYTE*)new char[flen];
bfile.Read(psf,flen);
bfile.Close();
pHead = acutBuildList(
AcDb::kDxfText,"1",
//AcDb::kDxfBinaryChunk,
//*psf,
AcDb::kDxfInt16,
*psf,
AcDb::kDxfText,
"This is a test Xrecord list",
AcDb::kDxfText,
"DocumentId",
0);
pXrec->setFromRbChain(*pHead);
acutRelRb(pHead);
pXrec->close();
