how to get the properties of a bitmap?

Question

How would I get the copyright date from a bitmap?

private void toolStripMenuItemLoadImage_Click(object sender, EventArgs e)
{
    using (OpenFileDialog ofd = new OpenFileDialog())
    {
        ofd.Title = "Load Image";

        if (ofd.ShowDialog() == DialogResult.OK)
        {
            firstLoaded = new Bitmap(ofd.FileName);
            String details = //Grab the copyright date of the image here; 
            this.Invalidate();
        }
    }
    isLoaded = true;
}

There's no space in the bitmap file format for such a thing. — Greg Hewgill, Mar 26 '12 at 05:24
i mean getting things like the date the image was created, last modified etc... is this possible? — BigBug, Mar 26 '12 at 05:30

If you're asking to get the system-provided details, then you should look into shell functions (shell32.dll). Check out this SO post.

Basically, it's not saved in the bitmap itself, rather in the system. It contains like specified rating, user, details etc.

Load the image into a bitmap object and access the exif data. See the second answer of this question: How to get the EXIF data from a file using C#

About access Time and co use the FileInfo class. See also the MSDN: http://msdn.microsoft.com/en-us/library/system.io.filesysteminfo.lastaccesstime.aspx

I didn't think EXIF data was stored in windows bitmap files. – Jonathon Reinhart Mar 26 '12 at 05:27

BMP files have AFIK no copyright data. Btw also if it's uncommon PNG supports EXIF too. – rekire Mar 26 '12 at 05:29
