【问题描述】:

如何获取 ai (Adobe Illustrator) 或 eps 文件的属性,即 dpi 分辨率等。 上传文件到服务器时需要检查这个属性。

还有任何 DLL 可以将 ai/eps 转换为标准图像格式(jpg、gif、png 等)吗?

    【解决方案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();
    
             }
        }
    

    要获取 ai 文件属性,如宽度、高度、页数和标题, 使用 itextsharp.dll

    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;
    
    
            }
    
        }
    }

      【解决方案2】:

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