如何在asp.net中将pdf转换为图像 [英] how to convert pdf to image in asp.net

问题描述

有人可以建议我如何在asp.net中将pdf转换为图像.我不想使用任何.exe文件，ghostscript，3rd party工具或其他任何工具.必须仅通过asp.net来实现.
我已经搜索了所有互联网资源，但没有用.

检查了这些文章，但它们使用了我不想使用的ghostscript和命令行等.

解决方案

这是不可能的.原因是:

1-ASP.NET是用于生成HTML的框架.后面的代码使用.NET框架，意味着您只想在ASP.NET项目中使用.NET框架(与ASP.NET部分无关)

2-.NET完全不支持PDF.零.因此，除非您编写自己的库来完全解析PDF，即重写您不想使用的那些商业库之一，否则没有其他方法可以在不购买库的情况下向.NET添加PDF支持. blockquote>

看起来描述PDF文件格式的ISO文档要花费几百美元.

您也可以尝试下载开源PDF渲染器并将其转换为您选择的.Net语言.

解决方案

This is impossible. The reasons are :

1 - ASP.NET is a framework for generating HTML. The code behind uses the .NET framework, you mean you want to use the .NET framework only, within an ASP.NET project ( and the ASP.NET part is irrelevant )

2 - .NET has NO PDF support at all. Zero. Therefore, unless you write your own library that fully parses PDFs, that is, rewrite one of those commercial libraries you don''t want to use, there is no other way to add PDF support to .NET without buying a library.

Looks like the ISO document describing the PDF file format costs a few hundred dollars.

You might also try downloading an open source PDF renderer and converting it to the .Net language of your choice.
