Question

我在Alfresco中使用了tesseract变换器，以便可以搜索TIFF图像。我已经找到了许多关于这个的教程，我已经在我的Alfresco上试过但是它没有用。

我在使用Alfresco Enterprise v5.0.2

似乎变压器没有集成，我上传了tiff图像但没有导致搜索单词。如何检查变压器是否已应用？

Answer 1

安装TESSTRACT OCR：从（https://code.google.com/p/tesseract-ocr/downloads/list）下载tesseract 然后双击tesseract-ocr-setup-3.02.02.exe安装它。

在系统“C：\ Program Files（x86）\ Tesseract-OCR”中安装tesseract后，将使用已安装的Tesseract OCR创建路径。

ALFRESCO已做出改变要添加的文件。 1）OCR.bat2）ocrpng变换-context.xml3）ocrjpeg变换-context.xml4）ocrtiff变换-context.xml5）露天-的tesseract-search.jar6）ocrtransform.log 1）OCR.bat

REM to see what happens
echo from %1 to %2 >>C:\tmp\ocrtransform.log


copy /Y %1 C:\TMP\%~n1%~x1

REM  call tesseract and redirect output to $TARGET
"C:\Program Files (x86)\Tesseract-OCR\tesseract.exe" C:\TMP\%~n1%~x1 %~d2%~p2%~n2 -l eng
del C:\TMP\%~n1%~x1

这个批处理脚本将放在你的露天路径“C：\ Alfresco”中

这个批处理脚本会将上传的文件发送到Tesseract ocr进行实际的OCR，将日志复制到ocrtransform.log，Tesseract OCR将内容发送到alfresco，我们可以更改上面文件默认给出的实际语言eng ，我们可以为此提供多种语言。

这些转换xml将添加到“C：\ Alfresco \ tomcat \ shared \ classes \ alfresco \ extension”

2）ocrpng变换-context.xml中

这些都是我们可以编写的转换文件。基于想要使用Tesseract进行OCR的文件的类型格式。

5）露天-的tesseract-search.jar 从这个链接下载这个罐子[{https://docs.google.com/file/d/0B94FD2QmPSJCNHpuUVlicW95UjA/edit)][1] 并将此jar放在此路径“C：\ Alfresco \ tomcat \ lib”中。 6）ocrtransform.log 使用“C：\ TMP”

中的ocrtransform.log创建一个空文件名

之后重启露天

然后上传图像格式的文件，图像的内容将在露天索引，以便我们可以搜索文件的内容。
