id3v2 mp3 image metadata

[faelnefal]

does anyone know at what point in an mp3 the image metadata is located? and if you do know, how do you convert the binary data into an image in a picturebox?

You are using TagLib#, right? Did you check their example:

try
{
   TagLib.File file = TagLib.File.Create ("/path/to/music/file.mp3");
   TagLib.Id3v2.Tag tag = file.GetTag (TagLib.TagTypes.Id3v2);
 
   // The file contains an ID3v2 tag.
   if (tag != null)
      foreach (TagLib.Id3v2.AttachedPictureFrame frame
                      in tag.GetFrames ("APIC"))
         SomeImageProcess (frame.Picture.Data);
}
catch {...}

yep taglib#, i looked at their example but i dont quite get it.

ive done what you suggested but it does not work
ive gotten error that says

"Cannot implicitly convert type 'TagLib.Tag' to 'TagLib.Id3v2.Tag'. An explicit conversion exists (are you missing a cast?)"

i also wish to display the picture in a picturebox

tnx!

I haven't used this so I cannot help.

Presuming that the returned TagLib.Tag can be cast to TagLib.Id3v2.Tag, the error that you are receiving could be solved with:

TagLib.Id3v2.Tag tag = file.GetTag (TagLib.TagTypes.Id3v2) as TagLib.Id3v2.Tag;
 

Try to get any image data to see what the returned format is, then you will decide how to display it. If it is a Bitmap object, then you can pass it to PictureBox.Image property and you're done. If not, then you will have to find or implement some conversions.
