Assuming you are using TJPEGImage, it already knows how to convert itself
to/from a TBitmap.  Just use the Assign() method, ie:

    Graphics::TBitmap *bmp = new Graphics::TBitmap;
    try
    {
        bmp->Assign(Image1->Picture->Graphic);
        // alter the bmp as needed...
        Image1->Picture->Graphic->Assign(bmp);
    }
    __finally {
        delete bmp;
    }

> import the BMP in my TImage component

No.  You operate on a separate TBitmap.  You do not put the bitmap into the
TImage while you are drawing on it.
