关于C# Image.SelectActiveFrame 轮询tif页，出现GDI+错误的问题(win svr 2008 r2)

[andison_karas]

求大神

1、特定tif（部分资料显示可能是由jpeg压缩制成的tif页会出错）才会出现本问题
2、该tif在Exception的win svr 2008上可以被系统图片浏览器打开
3、tif本身由TiffToy等工具都可以拆分、读取
4、而同一个tif同一段代码在win svr 2003/win 2010时不会Exception，win svr 2008 r2（数台2008皆有本问题）
5、tif地址：http://pan.baidu.com/s/1nvlVytj
6、代码如下

 using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;
using System.Runtime.InteropServices;
using System.Drawing;
using System.Drawing.Imaging;
namespace ConsoleApplication1
{
    class Program
    {

        static private ImageCodecInfo GetEncoder(ImageFormat format)
        {
            ImageCodecInfo[] codecs = ImageCodecInfo.GetImageDecoders();
            foreach (ImageCodecInfo codec in codecs)
            {
                if (codec.FormatID == format.Guid)
                {
                    return codec;
                }
            }
            return null;
        }

        static void Main(string[] args)
        {

            string str = string.Empty;
            while (true)
            {
                if (str != string.Empty)
                {
                    Console.WriteLine("ex 错误页" + str);
                }

                string sInt = Console.ReadLine();

                int E = 0;

                using (Image img = Image.FromFile(@"c:\test\011604372550903.tif"))
                {
                    Guid guid = (Guid)img.FrameDimensionsList.GetValue(0);
                    FrameDimension dimension = new FrameDimension(guid);
                    ImageCodecInfo codeInfo = GetEncoder(ImageFormat.Tiff);
                    System.Drawing.Imaging.Encoder saveEncoder = System.Drawing.Imaging.Encoder.SaveFlag;
                    EncoderParameters parameters = new EncoderParameters(2);
                    ImageCodecInfo codeInfobmp = GetEncoder(ImageFormat.Jpeg);

                    int totalPage = img.GetFrameCount(dimension);
                    for (int i = 0; i < totalPage; i++)
                    {
                        try
                        {
                            Console.WriteLine("Strat for " + (i + 1) + " SelectActiveFrame Pre");

                            img.SelectActiveFrame(dimension, Convert.ToInt32(i));
                        }
                        catch (Exception e)
                        {
                            E++;
                            str += " " + (i + 1).ToString();
                        }
                    }
                }
            }
        }
    }
}

错误截图
执行结果显示第2、第4、第7等页无法被读取，而1、3、5、6等页是没有问题的

7、tif工具导出并没有显示第2页和第3页标签的差别

[闭包客]

我之前处理 gif 的时候也是会出错的，后来下载了一个第三方的编码器。 我不知道 .NET 类库提供的编码器是否支持你所说的格式。

[andison_karas]

@closurer tiff格式默认是可以读取的，好像只是对tif中的jpeg的压缩格式有问题

看看你是不是这个问题http://stackoverflow.com/questions/32981128/when-converting-a-tif-to-a-jpg-i-get-the-error-a-generic-error-occurred-in-g

@Chinajiyong 不是这个哟。不过还是谢谢你 再找不到解决方案只能用libtiff做个工具给c#调了
