有没有显示ＪＰＧ的控件？

[mark521]

在基于对话框的窗口中要显示ＪＰＧ格式的图片，有没有相关的控件，如果没有，有什么其他的办法呢

使用GDI+非常容易！查找一下网上很多例子

GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);

Image* image = new Image(L"FakePhoto.jpg");
HDC hdc = GetDC(m_hWnd);
Graphics graphics(hdc);
graphics.DrawImage(image,10,10);

delete image;
GdiplusShutdown(gdiplusToken);
return 0;

6.0上没有ＧＤＩ　+Ａ

加到我的群里来吧：13073968
有VC6下使用的GDI+的头文件等

IDC_STATIC_PIC 为一个图形空件

bool CSoConvDlg::showPic()
{
CRect rect;
CDC* pDC;
IPicture *pPic;
IStream *pStm;

CFileStatus fstatus;
CFile file;
LONG cb;

if (file.Open(imgName,CFile::modeRead)&&file.GetStatus(imgName,fstatus)&&
((cb = fstatus.m_size) != -1))
{
HGLOBAL hGlobal = GlobalAlloc(GMEM_MOVEABLE, cb);
LPVOID pvData = NULL;
if (hGlobal != NULL)
{
if ((pvData = GlobalLock(hGlobal)) != NULL)
{
file.ReadHuge(pvData, cb);
GlobalUnlock(hGlobal);
CreateStreamOnHGlobal(hGlobal, TRUE, &pStm);

if(SUCCEEDED(OleLoadPicture(pStm,fstatus.m_size,TRUE,IID_IPicture,(LPVOID*)&pPic)))
{
OLE_XSIZE_HIMETRIC hmWidth;
OLE_YSIZE_HIMETRIC hmHeight;
pPic->get_Width(&hmWidth);
pPic->get_Height(&hmHeight);

//double fX,fY;
//fX = (double)pDC->GetDeviceCaps(HORZRES)*(double)hmWidth/((double)pDC->GetDeviceCaps(HORZSIZE)*100.0);
//fY = (double)pDC->GetDeviceCaps(VERTRES)*(double)hmHeight/((double)pDC->GetDeviceCaps(VERTSIZE)*100.0);
//if(FAILED(pPic->Render(*pDC,0,0,(DWORD)fX,(DWORD)fY,0,hmHeight,hmWidth,-hmHeight,NULL)))
double fX,fY;
fX = 640;
fY = 480;
pDC = GetDlgItem(IDC_STATIC_PIC)->GetDC();
//得到显示位置
GetDlgItem(IDC_STATIC_PIC)->GetWindowRect(rect);
if(FAILED(pPic->Render(*pDC,0,0,(DWORD)(rect.right - rect.left),(DWORD)(rect.bottom - rect.top),0,hmHeight,hmWidth,-hmHeight,NULL)))
{
//AfxMessageBox("Failed To Render The picture!");
pPic->Release();
file.Close();
ReleaseDC(pDC);
return false;
}
else
{
pPic->Release();
file.Close();
ReleaseDC(pDC);
return true;
}
}

}
else
{
//AfxMessageBox("Error Loading Picture From Stream!");
file.Close();
return false;
}
}

}
else
{//AfxMessageBox("Can't Open Image File!");
return false;
}
}


void CSoConvDlg::OnPaint()
{


//最后
imgName = "Corise.JPG";

showPic();
}

vc用IPicture接口

[cici2006]

你可以用PICTURE。H这个类型
