如何获取.ai或.eps文件的属性？

Question

我怎样才能得到AI（Adobe Illustrator中）或EPS文件即决议的性质DPI等 我需要上传文件到服务器时要检查这个属性。

而且没有任何DLL到AI/EPS转换为标准图像格式（JPG，GIF，PNG等）？

Answer 1

use ImageMagickNET.dll through this you can convert the .ai or .eps files into .jpg format.. 

C＃代码：

public partial class Form1 : Form 
    { 

     Process ffmpeg; 
     string video; 
     string thumb; 
     public Form1() 
     { 
      InitializeComponent(); 
     } 
     private void button4_Click(object sender, EventArgs e) 
     { 
      ffmpeg = new Process(); 

      ffmpeg.StartInfo.Arguments = "convert \"" + .ai file path + "\" -background white -flatten -density 300 -colors 512 -antialias -normalize -units PixelsPerInch -quality 100 -colorspace RGB -resize 3425x3425 \"D:\\GRAPHICS SEARCH ENGINE\\GRAPHICS IMAGES\\AI\\" convert.jpg\""; 

      ffmpeg.StartInfo.FileName = ("C:\\Program Files (x86)\\ImageMagick-6.5.3-Q16\\convert.exe"); 
      ffmpeg.Start(); 

     } 
    } 

为了得到这样的宽度，高度，页数和标题编号， 使用itextsharp.dll的AI文件的属性

代码：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Linq; 
using System.Text; 
using System.Windows.Forms; 
using iTextSharp.text; 
using iTextSharp.text.pdf; 

namespace pdfreared { public partial class Form1 : Form { public Form1() { InitializeComponent(); } 

    private void button1_Click(object sender, EventArgs e) 
    { 
     PdfReader reader = new PdfReader(@"D:\Files Formats\Icon.ai"); 
     int n = reader.NumberOfPages; 
     label4.Text = n.ToString(); 

     // size of the first page 
     Rectangle psize = reader.GetPageSize(1); 
     float width = psize.Width; 
     label1.Text ="Width= " + Convert.ToString(width); 
     float height = psize.Height; 
     label2.Text = "Height = " + Convert.ToString(height); 
     // reader.Metadata. 

     Console.WriteLine("Size of page 1 of {0} => {1} × {2}", n, width, height); 
     // file properties 
     Dictionary<string, string> infodict = reader.Info; 
     foreach (KeyValuePair<string, string> kvp in infodict) 
     { 
      Console.WriteLine(kvp.Key + " => " + kvp.Value); 
      label3.Text = kvp.Key + " => " + kvp.Value; 


     } 

    } 
} 

Answer 2

使用“identify -verbose image.eps”给出EPS文件和AI文件的元数据信息。
