怎样在不使用打印对话框情况下，把打印方向设为Landscape?

[plijin]

i have a big bitmap,whose width is more than it's height,so in order to
print it out,it seems always better to set the orientation to be landscape
without the trouble of display the print dialogue box,and change the attributs every time,i want to change the attribute to landscape by default for the users convenience,can anyone tell me how to do it

你为什么不改变文档的方向了：）
把bitmap转-90

what's the simplest method of rotating the bitmap

如果打印DC不是你自己创建的话用如下的方法.

1、调用CWinApp::GetPrinterDeviceDefaults(PRINTDLG* pPrintDlg)获得pPrintDlg

2、修改pPrintDlg变量里的pPrintDlg->hDevMode如下:
LPDEVMODE pDevMode = (LPDEVMODE)GlobalLock(pPrintDlg->hDevMode);
if(hDevMode)
{
pDevMode->dmOrientation = DMORIENT_LANDSCAPE;
GlobalUnlock(pPrintDlg->hDevMode);
}

必定成功！
