如何修复"Compression JPEG仅支持单个条带".问题 [英] How to fix "Compression JPEG is only supported with a single strip" issue

问题描述

我正在一个项目中，必须使用itextsharp创建PDF文件.但是，出现以下错误:

I'm working on a project in which I have to create a PDF file using itextsharp. However, I get the following error:

System.IO.IOException: Compression JPEG is only supported with a single strip. This image has 229 strips.
   at iTextSharp.text.pdf.codec.TiffImage.GetTiffImageColor(TIFFDirectory dir, RandomAccessFileOrArray s)
   at iTextSharp.text.pdf.codec.TiffImage.GetTiffImage(RandomAccessFileOrArray s, Int32 page, Boolean direct)
   at iTextSharp.text.Image.GetInstance(Uri url)
   at iTextSharp.text.Image.GetInstance(String filename)
   at TPDFG.Program.Main(String[] args) in f:\TPDF\TPDF\Program.cs:line 157

和行号我的代码中的157是:

and the line no. 157 in my code is:

Image _Image = Image.GetInstance(di.FullName + "\\" + ImageUrl);

一切正常，仅当嵌入式图像为TIFF并使用JPEG压缩压缩时，我才出现此错误.如果我使用未压缩的TIFF或LZW压缩的TIFF，则一切正常.

Everything works fine, I get this error only when the embedded image is TIFF and is compressed with JPEG Compression. If I use uncompressed TIFF or LZW compressed TIFF, everything works fine.

我不是图像专家，所以我不知道这个错误是什么意思.

I'm no image expert, so I don't know what this error mean.

我正在使用imagemagick命令行实用程序进行图像处理和转换.

I'm using imagemagick command line utility for image manipulation and conversion.

推荐答案

我刚刚找到了这篇文章，但它是针对itext java版本的.它说 iText不支持多条带状纸条.因此，我认为这对于itextsharp也同样适用.

I just found this article but its for itext java version. It says multi-strip tiffs aren't supported in iText. So I think this holds true for itextsharp as well.
