如何保存屏幕区域到图片呢？

[Juncof]

CFbsBitmap* iBitmap = new(ELeave) CFbsBitmap();
TRect rect(TPoint(0,0), TSize(iWeatherLtx, iWeatherPngLty);
CWsScreenDevice* screen = CCoeEnv::Static()-> ScreenDevice();
User::LeaveIfError(iBitmap->Create(rect.Size(), screen-> DisplayMode()));
screen->CopyScreenToBitmap(iBitmap, rect);
_LIT(KWeatherCity, "c:\\weather_1.png");
iBitmap->Save(KWeatherCity);
delete iBitmap;

保存之后图片使用mspaint打开说是不支持的文件格式。

我要解决方法，直接拿去用，没有时间搞。

请参考CMdaImageBitmapToFileUtility

[Juncof]

Code for screen capture TSize screenSize = CEikonEnv::Static()->ScreenDevice()->SizeInPixels();TDisplayMode displayMode = CEikonEnv::Static()->ScreenDevice()->DisplayMode(); CFbsBitmap*iBitmap = new (ELeave) CFbsBitmap(); User::LeaveIfError(iBitmap->Create(screenSize, displayMode)); TInt err = CEikonEnv::Static()->ScreenDevice()->CopyScreenToBitmap(iBitmap);iBitmap->Save(_L("c:\\system\\apps\\screen.mbm")); // here u can say // captured image as MBM
To convert it to .jpg TFileName filename;filename.Copy(_L("c:\\system\\apps\\1.jpg")); CImageEncoder* iencoder = CImageEncoder::FileNewL( CEikonEnv::Static()->FsSession(), filename,_L8("image/jpeg"), CImageEncoder::EOptionAlwaysThread); CleanupStack::PushL(iencoder);TRequestStatus aStatus = KErrNone; iencoder->Convert( &aStatus, *iBitmap );User::WaitForRequest( aStatus );CleanupStack::PopAndDestroy();

CFbsBitmap的Save的数据格式并不是按照标准的图片格式存储的
估计就是将内存中的2进制数据一流的方式写成文件

标记一下，虽然以后基本用不到了
