本文实例为大家分享了openoffice+jodconverter-code-3.0-bate4实现ppt转图片的具体代码，供大家参考，具体内容如下

安装openoffice4 （用于把文档(ppt)转成pdf）根据系统的位数安装使用jodconverter-core3.0-beta-4（要上传maven本地仓库）安装ImageMagick：yum install ImageMagick（用于pdf转图片）安装pdftotext 用于提取文字大纲 yuminstallpoppler-utilsperl脚本（用于提取pdf文档的文字大纲）

使用jodconverter调用OpenOffice 将office文档转换为PDF时。如果转换程序异常中止而OpenOffice并没有停止运行的话。

openoffice

1、启动tomcat时，启动openoffice服务（个人感觉有风险问题）

2、手工用命令，启动openoffice服务，在使用链接服务（推荐）

提取文字大纲的perl脚本：

use strict;use warnings;use utf8;use open ':encoding(utf8)';binmode(STDOUT, ":utf8");sub trim($){ my $string = shift; $string =~ s/^\s+//; $string =~ s/\s+$//; return $string;}if(!$ARGV[0]){ die;}open my $fh, "pdftotext -layout -enc UTF-8 $ARGV[0] - |" or die $!;my $firstline=<$fh>;print trim($firstline);my $pageNum = 1; while ( my $line = <$fh> ) { if ( $line =~ /\xC/ ) { my $count = ($line =~ tr/\xC//); for(my $i=0;$i<$count-1;$i++){ print "///".$pageNum; $pageNum++; } if(trim($line)){ print "///".trim($line); } $pageNum++; }}close $fh;

可能遇到的问题：

1、ppt转pdf时,遇到启动失败（不清楚是不是再次启动引起的）

2、转换后的pdf 表格里的中文会出现乱码

3、有时会出现关闭服务器的所用服务（尚不清楚什么原因引起的）

4、处理请求时，经常出现超时504
