Deflate压缩后，PDF页面显示为空白 [英] PDF pages show up blank after Deflate compression

问题描述

我已经在.NET中创建了一个应用程序，该应用程序可以从头开始创建基于简单文本的PDF文件.我已经成功创建了PDF文件，在其中放置了内容文本，例如Td(Hello World)Tj.

但是现在我想通过对内容应用某种形式的压缩来减小PDf文件的大小.到目前为止，我已经实现了本机.NET Gzip和zlib压缩类.我设法压缩了内容(文本)并大大减少了PDF文件的大小.但是要注意的是，当我在Acrobet Reader中打开PDF文件时，文件/页面是空白的，没有内容.尽管在记事本中打开PDF文件时，我仍然可以看到内容已被压缩.

我究竟做错了什么?下面是我在编写PDF内容时正在做的事情.我是否缺少一些必需的PDF元素标签?压缩以下是zlib.

I have created an application in .NET which creates simple text based PDF files from scratch. I have been successful in creating PDF files where I put content text as it is e.g. Td (Hello World) Tj.

But now I want to reduce the size of the PDf files by applying some form of compression to the content. I have so far implemented native .NET Gzip and zlib compression classes. I have managed to compress the content (text) and reduce the size of the PDF file considerably. But the catch is that when I open PDF file in Acrobet reader, the file/pages are blank with no content. Although when I open the PDF file in Notepad, I can see the content has been compressed.

What am I doing wrong? below is something that I am doing when writing PDF content. Am I missing some required PDF element tags? Below compression is zlib.
