How to store an image inside a file ?

Hi !

I try to create a file that contains some images (in JPEG or PNG format) and some other binary data.

To store the images, I plan to use GDI+ and the Image::Save() method. So I need an IStream object.

To store the other binary data, I plan to use the standard ofstream::write() method. So I need an ofstream object.

Are these two objects (IStream and ofstream) compatible ? And how can I find one from the other ?

Thanks for your help.

Why IStream? :confused:
Why not just use this overloaded method:

Code:

---

HRESULT Save(
    LPCTSTR pszFileName,
    REFGUID guidFileType = GUID_NULL) const throw();

---

:rolleyes:

Thanks VictorN for your answer.

The Save(pszFileName,guidFileType) method fits well when you have to store only an image in the file.
But, in my case, I have to write some other data before and after the image, in the same file. So I need to write the image in an opened file.
