卸载Adobe Acrobat出错

卸载Adobe Acrobat X程序时，总是报错1324，说Path Contains an Invalid Character（路径中包含无效字符）或multifonction.sequ。

日志报告显示错误来自于Mircrosoft的MsiInstaller

发现这个键值{AC76BA86-1033-F400-7760-000000000005}正好是Acrobat安装路径下Setup Files下文件夹的名字，里面有Acrobat 10的完整安装文件。

微软早期曾提供一个名为Windows Installer CleanUp utility的小工具来解决安装或卸载程序时出现的问题，不过现在被名为program install und uninstall troubleshooter（http://support.microsoft.com/mats/Program_Install_and_Uninstall ）的工具所替代。网上下载之后运行了估计约一刻钟才显示修复了卸载问题。不过原来的程序文件并未被移除，只是在安装的程序列表里没有了。

xdp文件变大问题

今天留意到我这几天正编辑的xdp文件已经到了8MB了，原来不过仅仅几百KB。这又让我想到经常代码写进去后在design view下看不到，只有在xml source界面下才能看到，并且是重复的。

网上google的结果是，这是Livecycle Designer ES 8.2的一个Bug造成的。
A bug introduced with LiveCycle Designer ES Update 1 (8.2) is now fixed in LiveCycle service pack 2 and the Acrobat 9.1 update. The bug causes a processing instruction ex. <?templateDesigner StyleID aped3?> to get copied repeatedly while working with the form. This can lead to extremely large file sizes and sometime causes crashes. The fix removes duplicate StyleID's found in existing forms and prevents them from being created.

在LiveCycle Designer下调试javascript

在Firefox下用惯了用firebug去调试javascript，现在在Livecycle Designer下也希望有一个这样的工具。查了半天文档才发现在Acrobat下打开javascript debugger（Edit -> Preferences, Select Enable Interactive Console and Show Console On Errors And Messages），可以在Livecycle Designer下用control + j打开。让人费解的是如何执行interactive console下的代码，必须先选中要执行的代码，再按control+enter，才能执行。

Using the JavaScript Console from Acrobat, you can to evaluate single or multiple lines of code.
There are three ways to evaluate JavaScript code while using the interactive JavaScript Console:
• To evaluate a portion of a line of code, highlight the portion in the console window and press either Enter on the numeric keypad or Ctrl+Enter on the regular keyboard.
• To evaluate a single line of code, make sure the cursor is positioned in the appropriate line in the console window and press either Enter on the numeric keypad or Ctrl+Enter on the regular keyboard.
• To evaluate multiple lines of code, highlight those lines in the console window and press either Enter on the numeric keypad or Ctrl+Enter on the regular keyboard.

Font Substitution with Acrobat

Acrobat提供一个特性，把显示文档所需的字体嵌入到文件中，而不必把整个字体文件嵌入到文件中，因此能明显减小文件的大小。如果发送一个中文的pdf文档给一位使用西文操作系统的用户，这时最好使用font substitution，以保证这个文件在他的系统中能正常被现实和打印。

Font substitution in PDF will occur when the computer does not have access to the original font. If the original font is not present, an Adobe Multiple Master typeface is temporarily substituted for missing fonts— AdobeSerifMM for a serif fonts, and AdobeSansMM for sans serif fonts.

Documents submitted to technical review by the agency may contain formulas and other scientific characters. To prevent the possibility of a character being incorrectly substituted, documents must have fonts embedded.

Modern font sets often contain thousands of characters. Completely embedding a font greatly increases the file size of the resulting PDF. The solution is font subsetting. Subsetting only embeds the characters that are necessary to render the page. Visually, a document with subset fonts and completely embedded fonts looks and prints identically.
