问题描述

如何编辑JPG文件标题，主题，注释和标签/关键字?*

How do I edit JPG File Title, Subject, Comments, and Tags/Keyowrds?*

我已经尝试过问这个问题这里:

I have already tried asking this question here:

提供的Exif信息很有帮助，但最终并没有真​​正解决我正在研究的真正难题.因此，我将从另一个角度来描述所需的结果:

The Exif information provided was helpful, but in the end did not actually solve the real riddle I was working on. So I'll take another angle at describing the desired result:

我希望我的VB.NET应用程序允许我编辑Jfile的以下详细信息(见图片):

I want my VB.NET app to allow me to edit the following details of a Jfile (see image):

标题，主题，评论和标签/关键字

Title, Subject, Comments, and Tags/Keyowrds

• 我有一个方便的图像可以包含但没有足够的积分来张贴它.弱.

在窗口中右击.JPG并选择属性"

RIGHT CLICK A .JPG IN WINDOWS and select PROPERTIES

任何人都可以解释如何在Visual Studio中通过VB.net编辑这些字段吗?

Can anyone explain how to edit those fields through VB.net in Visual Studio?

最终目标是使用我构建的图像查看器/编辑器，对我多年来收集的成千上万张随机Web垃圾图像进行分类. 在查看图像(比如说"00001.jpg")并弄清楚它是什么(吊顶猫送儿子"大声笑猫的图片)之后，我要输入说明(已在表格中完成).当我按Enter键时，我想将文件重命名(从"00001.jpg"重命名为"ceiling-cat-sends-son.jpg"，然后用相同的数据填写关键字，标题，主题和注释字段:天花板猫送儿子".

The ultimate goal is to use the image viewer/editer that I built, to sort thousands of images of random webjunk I have collected over the years. Upon viewing the image (say "00001.jpg") and figureing out what it is ("ceiling cat sends son" picture of a lol cat), I want to type in the description (already done in the form). When I hit enter I want to rename the file (from "00001.jpg" to "ceiling-cat-sends-son.jpg", then fill in the keywords, title, subject, and comments fields with the same data: "ceiling cat sends son".

这将有助于本地索引编制，以及(稍后)使SQL Server引用数据库自​​动化以供在我的网站上进行站点范围内的搜索时使用.我似乎无法弄清的唯一事情就是如何修改这四个字段，就像我右键单击文件并添加关键字一样.

This will help with local indexing and with my (later) automating a SQL server referential database for use with site wide searches on my website. The ONLY thing I can't seem to figure out is how to modify those four fields as if I had right-clicked the file and added the keywords.

推荐答案

由于我不使用VB.Net，并且只能读取EXIF数据，因此我只能为您提供一个起点.在C#中，如果您使用以下命令在System.Drawing.Image实例中打开文件:

I can only offer you a starting point, since I don't use VB.Net and I only read EXIF data. In C#, if you open file in a System.Drawing.Image instance using:

Image image = System.Drawing.Image.FromFile("path/to/file.jpg");

您可以使用image.GetPropertyItem(0x0112)访问原始EXIF数据，其中列出了所有可用属性项的列表:

You can access the raw EXIF data by using image.GetPropertyItem(0x0112), where the list of all available property items are listed here:

http://msdn.microsoft.com/zh-cn/library/ms534418％28VS.85％29.aspx

同样，有一个image.SetPropertyItem(0x0112)方法，但是我认为这只会在内存中设置它，并且您必须保存图像的副本才能写出来.我认为您想要的是在不触摸实际图像的情况下修改EXIF的能力，而我不知道该怎么做.

Likewise, there's an image.SetPropertyItem(0x0112) method, but I think that will only set it in memory and you will have to save a copy of the image in order to write it out. I think what you want though is the ability to modify the EXIF without touching the actual image, which I do not know how to do.

正如我在评论中所说，我建议不要创建包含此类信息的Media类，而不是编辑图像标题信息:

As I've said in my comment, I recommend that instead of editing the image header information, you should create a Media class that holds that kind of information:

public class Media
{
    public string Title { get; set; }
    public string Subject { get; set; }
    public string Comments { get; set; }
    public string[] Tags { get; set; }
    public string PathToFile { get; set; }
}

然后，您可以将此记录存储在数据库中，这使搜索变得非常容易.如果需要实际文件，请使用PathToFile属性找到它.

Then you would store this record in the database, which makes it really easy to search on. If you need the actual file, use the PathToFile property to locate it.
