HICON图标保存失真

[coffee_machine]

我从任意格式的文件中，获取这个文件的图标的HICON,

if(HICON != NULL)
{

//利用HICON句柄导出.ico文件进行保存
//但每次保存的.ico文件，严重失真

}

哪位可以给我说一个思路或方法的，先谢过了

有什么导出的不失真的方法吗?

你是怎么保存的，把你保存的代码贴上来

图标的颜色只支持256色吧

xp下32位带alpha通道的都支持

[coffee_machine]

CString szFileName = "D:\\Word.exe";
SHFILEINFO shfi;
memset (&shfi, 0, sizeof(shfi));
SHGetFileInfo (szFileName, //文件名
FILE_ATTRIBUTE_NORMAL,
&shfi,
sizeof (shfi),
SHGFI_ICON | SHGFI_USEFILEATTRIBUTES |SHGFI_LARGEICON);

HICON hIcon = CopyIcon(shfi.hIcon);

再用hIcon导出*.ico文件

[coffee_machine]

void CmenuDlg::SaveIcoToFile(HICON hIconToSave, LPCTSTR sIconFileName)
{
if(hIconToSave==NULL || sIconFileName==NULL)
return;
PICTDESC picdesc;
picdesc.cbSizeofstruct = sizeof(PICTDESC);
picdesc.picType = PICTYPE_ICON ;
picdesc.icon.hicon = hIconToSave;

IPicture* pPicture=NULL;
OleCreatePictureIndirect(&picdesc, IID_IPicture, TRUE,(VOID**)&pPicture);
LPSTREAM pStream;
CreateStreamOnHGlobal(NULL,TRUE,&pStream);
LONG size;
HRESULT hr=pPicture->SaveAsFile(pStream,TRUE,&size);
char pathbuf[1024];
strcpy(pathbuf,sIconFileName);
CFile iconfile;
iconfile.Open(pathbuf, CFile::modeCreate|CFile::modeWrite);
LARGE_INTEGER li;
li.HighPart =0;
li.LowPart =0;
ULARGE_INTEGER ulnewpos;
pStream->Seek( li,STREAM_SEEK_SET,&ulnewpos);
ULONG uReadCount = 1;
while(uReadCount>0)
{
pStream->Read(pathbuf,sizeof(pathbuf),&uReadCount);
if(uReadCount>0)
iconfile.Write(pathbuf,uReadCount);
}
pStream->Release();
iconfile.Close();

}
//这个是用HICO保存为ICO文件的代码
//以上是引用他人的代码

经过研究,把数据提出来,自己写//位图信息+调色板+彩色位图位值+掩码位图位值 构成*.ico文件,就不会失真
