How to Convert IPicture to Image - .NET 4.5 TagLib Sharp

问题

I am wanting to display the album artwork of a song (accessed via the taglib-sharp library) within a Windows Forms picture box. The problem I'm running into is that the taglib-library returns an image of type TagLib.IPicture whereas the picture box requires an object of type System.Drawing.Image.

I have scoured the internet for many hours now, looking for a way to convert from an IPicture to Image, but to no avail. The best lead I have is this: http://msdn.microsoft.com/en-us/library/system.windows.forms.axhost.getpicturefromipicture.aspx, but I have yet to see a successful example of how to implement this.

Any help as to how to convert between these two types would be much appreciated. Note: IPicture is not analogous to IPictureDisp in this case.

回答1:

I've done the opposite before - turning an existing .jpg into an IPicture for embedding in an .mp3 file. I just tried reversing that operation and, after tweaking and testing, came up with this:

TagLib.File tagFile = TagLib.File.Create(mp3FilePath);
MemoryStream ms = new MemoryStream(tagFile.Tag.Pictures[0].Data.Data);
System.Drawing.Image image = System.Drawing.Image.FromStream(ms);

Thanks for the question - I already know how I'm going to use this myself!

Update: Here's the other way (.jpg to IPicture that I've done before):

tagFile.Tag.Pictures = new TagLib.IPicture[]
{
    new TagLib.Picture(new TagLib.ByteVector((byte[])new System.Drawing.ImageConverter().ConvertTo(System.Drawing.Image.FromFile(jpgFilePath), typeof(byte[]))))
};
