是否有工具来分析PDF的字体,对象,字段及其各自的大小(kb)？

Question

是否有工具来分析PDF的字体,对象,字段及其各自的大小？如果它在Windows上运行会很有帮助.

我正在尝试通过abcPDF优化我们生成的PDF的大小.

Answer 1

在“信息工具”的多价可以回答你的问题：

Multivalent是一个跨平台的 Java 应用程序

下载链接（带有工具的最新免费版本 - 在 sourceforge 上托管的构建不再有 pdf 工具，只有 pdf 查看器，所以，不要从 sourceforge 下载）

• https://rg.to/file/c6bd7f31bf8885bcaa69b50ffab7e355/Multivalent20060102.jar.html

用：

java -cp /pathto/Multivalent.jar tool.pdf.Info -all file.pdf

输出将如下所示：

事实证明，acrobat 中有一个优化器，即“PDF 优化器”，它可以提供所有这些信息。
