如何将IPicture转换为图像-.NET 4.5 TagLib Sharp

问题描述

我想在Windows窗体图片框中显示歌曲的专辑插图（可通过taglib-sharp库访问）。我遇到的问题是，taglib库返回的图像类型为 TagLib.IPicture ，而图片框需要的对象类型为 System .Drawing.Image 。

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.

我已经在互联网上搜寻了很多小时，正在寻找一种方法来从 IPicture 到图片，但无济于事。我最好的线索是：，但是我还没有看到如何实现此效果的成功示例。

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.

关于如何在这两种类型之间进行转换的任何帮助将不胜感激。 注意： IPicture 在这种情况下与 IPictureDisp 类似。

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.

推荐答案

我之前做过相反的工作-将现有的.jpg转换为IPicture，以嵌入到.mp3文件中。我只是尝试反转该操作，并且在进行了调整和测试之后，提出了以下建议：

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);

感谢您提出问题-我已经知道自己将如何使用它！

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

更新：这是另一种方式（.jpg到我之前做过的IPicture）：

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[]))))
};
