Rotate an image

[bernie31]

Hi,

I have a bmp image and I want to rotate it.

I try to do by the following code but the image is unchanged. I don't understand why it doesn't work.

Thank you very much for your help.

// .CPP FILE

#include "MyApp.h"

#include <BitmapTransforms.h> //Rotation

#include <MyApp.mbg> // Contains icon enumeration
#include <MyApp.rsg> // R_ICON_FILE_NAME

// ================= MEMBER FUNCTIONS =======================

CMyApp* CMyApp::NewLC(MConverterController* aController)
{
  CMyApp* self = new( ELeave )CMyApp(aController);
  CleanupStack::PushL( self );
  self->ConstructL();
  return self;
}

CMyApp* CMyApp::NewL(MConverterController* aController)
{
  CMyApp* self = CMyApp::NewLC(aController);
  CleanupStack::Pop( self );
  return self;
}

CMyApp::CMyApp(MConverterController* aController) : iController( aController ), CActive( EPriorityNormal )
{
}

void CMyApp::ConstructL()
{
   iBitmapRotator = CBitmapRotator::NewL();

  CActiveScheduler::Add( this );
}

CMyApp::~CMyApp()
{
delete iBitmapRotator;

}

void CMyApp::DrawClock(CFbsBitmap * aBmp)
{

iBitmapRotator->Rotate(&iStatus, *aBmp, CBitmapRotator::EMirrorVerticalAxis);

SetActive();
}

void CMyApp::RunL()
{
  iController->NotifyCompletion( KErrNone );
}

void CMyApp::DoCancel()
{
}

//----------------
// .H FILE

class MConverterController
        {
        public:
                virtual void NotifyCompletion( TInt aErr ) = 0;
        };


class CBitmapRotator;

class CMyApp: public CActive
{
public: // // Constructors and destructor

  static CMyApp* NewLC(MConverterController* aController);
  static CMyApp* NewL(MConverterController* aController);

  /** Symbian default constructor. */
  void ConstructL();

  /** Destructor. */
  ~CMyApp();

  CMyApp(MConverterController* aController);

public: // New functions

  void DrawClock(CFbsBitmap * aBmp);


public: // CActive

        virtual void RunL();

        virtual void DoCancel();


private: //Data
  CBitmapRotator* iBitmapRotator;
  
  MConverterController* iController; // ui controller


//-----------


//And I use this class, like this :

//CFbsBitmap * iBmp;
iBmp = CEikonEnv::Static()->CreateBitmapL( * iconFileName, EMbmMyAppAiguille );

//CMyApp * iDraw;
iDraw = CMyApp::NewL(this);
iDraw->DrawClock(iBmp);

Thank you.
