Routines for displaying image files (.BMP .DIB .EMF .GIF .ICO .JPG .WMF)

After many days of searching (and not finding) a way to load a JPG from a resource and show it on a dialog based application, I decided to take steps

So I created what I call a very simple and useful class, it can easily be implemented by adding it to a project, and you do not have to be a real JPEG freak and invent all header reading from the beginning (it uses the IPicture interface - same way as Internet Explorer does)

About The Project

I was little carried away with this "ACDSee alike" picture viewer, as it was not my main purpose - I did not have the time to make it "perfect", if you feel lucky and want to improve it here and there then please share it with me.

class CPicture
{
public:
	void FreePictureData();
	BOOL Load(CString sFilePathName);
	BOOL Load(UINT ResourceName, LPCSTR ResourceType);
	BOOL LoadPictureData(BYTE* pBuffer, int nSize);
	BOOL SaveAsBitmap(CString sFilePathName);
	BOOL Show(CDC* pDC, CPoint LeftTop, CPoint WidthHeight, int MagnifyX,
                  int MagnifyY);
	BOOL Show(CDC* pDC, CRect DrawRect);
	BOOL ShowBitmapResource(CDC* pDC, const int BMPResource, 
                                CPoint LeftTop);
	BOOL UpdateSizeOnDC(CDC* pDC);

	CPicture();
	virtual ~CPicture();
        // Same As LPPICTURE (typedef IPicture __RPC_FAR *LPPICTURE)
	IPicture* m_IPicture; 
	// Height (In Pixels Ignor What Current Device Context Uses)
	LONG m_Height; 	     
        // Size Of The Image Object In Bytes (File OR Resource) 
        LONG m_Weight;	
        // Width (In Pixels Ignor What Current Device Context Uses)
         LONG m_Width;  
};
//~~~~~~~~~~~~~~~~~~~~~~~~~~Example & Usage 4 Dummies~~~~~~~~~~~~~~~~~~~~~~~~
//
//  U Need 2 Add "CPicture.CPP" and "CPicture.H" Into Your Project 
// (From FileView)
//  So U Will Get Control Over The Functions In This Class,
//  Then U Can Create a Picture Object And Show It On a Device Context
//
// Create a Picture Object (An Instance Of This Class)
//  CPicture m_Picture;  

// Make Sure U Include This Where U Gonna Create The Object...
//  #include "Picture.h" 
//  Load Picture Data Into The IPicture Interface 

(.BMP .DIB .EMF .GIF .ICO .JPG .WMF)
//  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

// Load From a File - Just Load It (Show Later)
//	m_Picture.Load("Test.JPG"); 
// Load From a Resource - Just Load It (Show Later)
//	m_Picture.Load(IDR_TEST, "JPG"); 

//  (U Must Include IDR_TEST In Your Resources Under a Custom Name, 4 
//   Example - "JPG")
//  
//  When Using DC Object On a *Dialog Based* Application (CPaintDC dc(this);)
//  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//	
// Get Picture Dimentions In Pixels
//      m_Picture.UpdateSizeOnDC(&dc); 
//	m_Picture.Show(&dc, CPoint(0,0), 
                       CPoint(m_Picture.m_Width, m_Picture.m_Height), 0,0);
//	
//      Change Original Dimentions
//      m_Picture.Show(&dc, CRect(0,0,100,100)); 

//      Show Bitmap Resource
//	m_Picture.ShowBitmapResource(&dc, IDB_TEST, CPoint(0,0)); 
//
//  OR When Using a Pointer On a "Regular" MFC Application (CDC* pDC)
//  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//	m_Picture.UpdateSizeOnDC(pDC); // Get Picture Dimentions In Pixels
//	m_Picture.Show(pDC, CPoint(0,0),  CPoint
//                     m_Picture.m_Width,m_Picture.m_Height), 0,0);
//      Change Original Dimentions
//	m_Picture.Show(pDC, CRect(0,0,100,100)); 
//      Show Bitmap Resource
//	m_Picture.ShowBitmapResource(pDC, IDB_TEST, CPoint(0,0)); 
//  Show Picture Information
//  ~~~~~~~~~~~~~~~~~~~~~~~~
//	CString S;
//	S.Format("Size = %4d\nWidth = %4d\nHeight = %4d\nWeight = %4d\n",
//	         m_Picture.m_Weight, m_Picture.m_Width, 
//               m_Picture.m_Height,  m_Picture.m_Weight);
//	AfxMessageBox(S);
