-------------------------------------------------------------------------------- 1 | CHANGELOG of java-thumbnailer 2 | ----------------------------- 3 | 4 | + Add Feature 5 | * Bugfix 6 | # Enhance Feature 7 | 8 | 9 | v0.6 10 | ---- 11 | (05. December 2012) 12 | * Delete Thumbnails that were not saved in the index. (This can happen if crawling happens several times a day, as the document is only indexed once a day.) 13 | + JODConverterThumbnailer: Port can now be configured. 14 | + Automatic regain installation via ant (see https://github.com/benjaminpick/java-thumbnailer/wiki/Building-from-source) 15 | * Fix possible NullPointerException for Office2007FileIdentifier 16 | + Change Mime Type in regain index to detected one (our mime type detector is more accurate than regain's) 17 | 18 | v0.5 19 | ---- 20 | (30. March 2012) 21 | * Catch all errors of POI (no idea in which edge case this could change something) 22 | * MS-Office-FileIdentifiers does not need temporary files anymore. 23 | * Improve Perfomance of PDFBox a little bit 24 | * Centralise handling of temporary files 25 | * Add HTML thumnailing (rudimentary) 26 | 27 | v0.4 28 | ---- 29 | (5. January 2012) 30 | 31 | + Add Apache POI 3.7 32 | * Update JODConverter to latest version in SVN 33 | + Old Office Files are now detected via MIME => Performance improvement: Zip files can quicker be detected as non-office file 34 | 35 | Failing Tests: 36 | - ChainedHashtable: testBacking (not important, as currently not used) 37 | - ThumbnailersFailingTest: testFailingJOD (JOD may falsely claim having succeeded when converting a binary file) 38 | - MIMEDectectionExtensiveTest: txt-related (10) (Txt files cannot be detected by content - should we detect ASCII-Files?) 39 | 40 | v0.3 41 | ---- 42 | (9. August 2011) 43 | 44 | * Make Lucene Value "filelocation" relative to thumnailFolder 45 | * Changed Lucene Value "no thumbnailer found" to "nothumbnailerfound" (to avoid tokenizing) 46 | * Add to taglib 47 | 48 | v0.2 49 | ---- 50 | (2. August 2011) 51 | 52 | + MIME-Test: Office2007-Files & OpenOffice files are detected via Zip/XML 53 | # Upgrade PDFBox 1.5.0 -> 1.6.0 54 | * JODConverter didn't delete his temporary files if conversion failed 55 | 56 | Failing tests: 57 | - ChainedHashtable: testBacking (not important, as currently not used) 58 | - MimeDetectionTest: testOfficeFiles{1,2,3} (meaning only that conversion takes longer than necessary) 59 | - ThumbnailersFailingTest: testFailingJOD (JOD may falsely claim having succeeded when converting a binary file) 60 | 61 | v0.1 62 | ---- 63 | (29. July 2011) 64 | 65 | First public release. 66 | -------------------------------------------------------------------------------- /INSTALL: -------------------------------------------------------------------------------- 1 | This document is intended to help you getting started. 2 | The most recent instructions can be found at https://github.com/benjaminpick/java-thumbnailer/wiki/Installation 3 | 4 | --- 5 | 6 | Installation 7 | ============ 8 | 9 | There are two versions of JavaThumbnailer: 10 | 11 | * If you want to include this as a library to your own project, or use it from command-line only, you should take the **Standalone Version**. 12 | * For integration into the regain Desktop search, take the **Regain Plugin Version**. 13 | 14 | ## Standalone Version 15 | 16 | 1. Get the recent version of JavaThumbnailer at the [Download Page](https://github.com/benjaminpick/java-thumbnailer/releases) (or [build it from source](Building from Source).) 17 | 2. To run it via the commandline: `java -jar javathumbnailer-standalone.jar input.doc [output.png]` 18 | 3. To use it in your own project, include this `.jar` in your classpath. For an example of usage (and configuration), see the code in [Main.java](https://github.com/benjaminpick/java-thumbnailer/blob/master/src/de/uni_siegen/wineme/come_in/thumbnailer/Main.java). 19 | 20 | ## Regain Plugin Version 21 | 22 | 0. Get the recent version of [regain](http://regain.sourceforge.net/download.php). 23 | 1. Get the recent version of JavaThumbnailer at the [Download Page](https://github.com/benjaminpick/java-thumbnailer/releases) (or [build it from source](Building from Source).) 24 | 25 | ### Crawler Plugin 26 | 2. Save javathumbnailer-crawlerplugin-${version}.jar it into the `/plugins/`-Folder of regain. 27 | 3. Edit `CrawlerConfiguration.xml` to suit your needs. Here are the default values: 28 | 29 | 33 | 34 | de.uni_siegen.wineme.come_in.thumbnailer.plugin.ThumbnailerPlugin 35 | 36 |
37 | 39 | thumbs/ 40 | 41 | 42 | 160 43 | 120 44 |
45 |
46 | 47 | 48 | 49 | 50 | 51 |
52 | 53 | 54 | 55 | ### Search 56 | 57 | 4. Extract `web/` to your web/-Folder (Server: deployed folder). It contains: 58 | * `search_example.jsp` : Modified version of `regain/web/common/search.jsp` . If you didn't modify it, you can overwrite the regain version of `search.jsp`. 59 | * `img/image_missing.png` : Example of an image that is shown instead of the thumbnail when thumbnail generation failed 60 | * `taglib/regain-thumbnailer.tld` : Tag declarations. Used only by the server version. 61 | * `taglib/thumbnailer.jar`: Tag implementations. Used by server & desktop version. 62 | 63 | #### Desktop Search 64 | *(If you don't use the desktop search, you can skip this section.)* 65 | 66 | 5. Add the thumbnailer-Tag in `DesktopConfiguration.xml`: 67 | 68 | 69 | 70 | 71 | net.sf.regain.search.sharedlib 72 | net.sf.regain.ui.desktop.config.sharedlib 73 | net.sf.regain.ui.desktop.status.sharedlib 74 | 75 | 76 | de.uni_siegen.wineme.come_in.thumbnailer.plugin.sharedlib 77 | 78 | 79 | #### Server Search 80 | *(If you don't use the tomcat server search, you can skip this section.)* 81 | 82 | 6. Copy `web/taglib/thumbnailer.jar` into the deployed application folder `WEB-INF/lib`. 83 | 7. Make sure you added `<%@taglib uri="taglib/regain-thumbnailer.tld" prefix="thumbnailer" %>` at the top of your jsp where you use the tag ``. 84 | 8. Restart Tomcat or the regain-application. 85 | 86 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | Thumbnailer 2 | =========== 3 | 4 | This is a Java Plugin for creating Thumbnails of files during the crawling process of regain.
5 | It can also be used as a standalone library to create thumbnails of different file types (image, text).
6 | (Regain is a Lucene-based desktop search engine.) 7 | 8 | *Current Version* : 0.6 (Beta)
9 | *Licence* : GNU GPL 2.1 or later 10 | 11 | Similar Project: 12 | 13 | * https://code.google.com/p/thumbnailator/ only for images 14 | 15 | Requirements 16 | ------------ 17 | 18 | * Java JRE 1.8 19 | * (optional) OpenOffice 3.x/LibreOffice 20 | * Tested in Windows/Linux/Mac 21 | 22 | Supported Fileformats 23 | --------------------- 24 | 25 | * Office files (doc, docx, xls, xlsx, ppt, pptx) 26 | * OpenOffice files (all of them) 27 | * Text files (txt, pdf, rtf, html) 28 | * Image files (jpg, png, bmp, gif) 29 | * MIT Scratch files (sb) 30 | * AutoCad files (dwg) 31 | 32 | (Detection is based on MIME-Type, not filename extension. So files with an incorrect file extension will be treated correctly, not as they deserve.) 33 | 34 | Output are always PNG files. The dimension of this Thumbnail can be configured. 35 | 36 | TODO 37 | ---- 38 | 39 | ### Thumbnailer: 40 | * JODConverter 3beta 41 | * Upgrade to 3beta5 when it appears 42 | * remove log4j info messages 43 | * Find a way to let him fail if he can't convert the file (sb is a binary format and really shouldn't be treated as plain text.) 44 | * PDFBox: Library Conflict with regain. (We need to include this in the plugin, but it is included in a maybe-loaded preparator as well.) 45 | * That means that both should be updated at the same time! 46 | 47 | 48 | Author 49 | ------ 50 | 51 | This is a project of the university of Siegen for the benefit of [come_IN Computerclubs](http://www.computerclub-comein.de). But of course, if you have patches etc. go ahead! 52 | -------------------------------------------------------------------------------- /build.properties.template:

(JODConverter will actually only use copies of it, so it won't get modified.) 5 | 6 | 1. Go to the commandline and type: 7 | 8 | soffice -env:UserInstallation=[profile dir here] 9 | 10 | (You may need to go to the OpenOffice-Directory first.) 11 | 2. Now Openoffice starts within this profile, creating it if it didn't exist yet. 12 | 3. Change any preferences you like. 13 | 4. Close the window. 14 | 15 | Now go to CrawlerConfiguration.xml and tell the JavaThumbnailer where to look for a such profile (scroll down to crawlerPlugin > section:externalHelpers > param:openOfficeProfile ) 16 | 17 | -------------------------------------------------------------------------------- /ressources/conf/javathumbnailer.log4j.properties: -------------------------------------------------------------------------------- 1 | # NOTE: cascaded variable substitution doesn't work! 2 | 3 | # The root category 4 | log4j.rootCategory=INFO, file, stdout 5 | 6 | # Special categories 7 | # Disable log messages from PDFBox 8 | log4j.category.org.apache.pdfbox.util.PDFStreamEngine=WARN 9 | # Disable Font replacement warnings from PDFBox 10 | log4j.category.org.apache.pdfbox.pdmodel.font.PDSimpleFont=ERROR 11 | 12 | # Some layouts 13 | #layout.example.1=%d{dd/MM/yyyy HH:mm:ss} [%-5p](%F:%L) %m%n 14 | #layout.example.2=%d{dd/MM/yyyy HH:mm:ss} [%t] %-5p %c{2} - %m%n 15 | layout.long=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p: %m%n 16 | layout.medium=%d{HH:mm:ss}: %m%n 17 | layout.short=%m%n 18 | 19 | 20 | # The console appender 21 | log4j.appender.stdout=org.apache.log4j.ConsoleAppender 22 | 23 | # The console appender layout 24 | log4j.appender.stdout.layout=org.apache.log4j.PatternLayout 25 | log4j.appender.stdout.layout.ConversionPattern=${layout.medium} 26 | 27 | # The file appender 28 | log4j.appender.file=org.apache.log4j.RollingFileAppender 29 | 30 | # Log only errors to the log file 31 | log4j.appender.file.Threshold=ERROR 32 | 33 | # The file appender layout 34 | log4j.appender.file.layout=org.apache.log4j.PatternLayout 35 | log4j.appender.file.layout.ConversionPattern=${layout.long} 36 | 37 | # Path of the log-file 38 | log4j.appender.file.File=log/regain.log 39 | 40 | # Maximum size of the log-file (only org.apache.log4j.RollingFileAppender) 41 | log4j.appender.file.MaxFileSize=2MB 42 | 43 | # Amount of backup files (only org.apache.log4j.RollingFileAppender) 44 | log4j.appender.file.MaxBackupIndex=2 45 | -------------------------------------------------------------------------------- /ressources/dummy-jdk-api-doc/package-list: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | java.applet 5 | java.awt 6 | java.awt.color 7 | java.awt.datatransfer 8 | java.awt.dnd 9 | java.awt.event 10 | java.awt.font 11 | java.awt.geom 12 | java.awt.im 13 | java.awt.im.spi 14 | java.awt.image 15 | java.awt.image.renderable 16 | java.awt.print 17 | java.beans 18 | java.beans.beancontext 19 | java.io 20 | java.lang 21 | java.lang.ref 22 | java.lang.reflect 23 | java.math 24 | java.net 25 | java.rmi 26 | java.rmi.activation 27 | java.rmi.dgc 28 | java.rmi.registry 29 | java.rmi.server 30 | java.security 31 | java.security.acl 32 | java.security.cert 33 | java.security.interfaces 34 | java.security.spec 35 | java.sql 36 | java.text 37 | java.util 38 | java.util.jar 39 | java.util.zip 40 | javax.accessibility 41 | javax.naming 42 | javax.naming.directory 43 | javax.naming.event 44 | javax.naming.ldap 45 | javax.naming.spi 46 | javax.rmi 47 | javax.rmi.CORBA 48 | javax.sound.midi 49 | javax.sound.midi.spi 50 | javax.sound.sampled 51 | javax.sound.sampled.spi 52 | javax.swing 53 | javax.swing.border 54 | javax.swing.colorchooser 55 | javax.swing.event 56 | javax.swing.filechooser 57 | javax.swing.plaf 58 | javax.swing.plaf.basic 59 | javax.swing.plaf.metal 60 | javax.swing.plaf.multi 61 | javax.swing.table 62 | javax.swing.text 63 | javax.swing.text.html 64 | javax.swing.text.html.parser 65 | javax.swing.text.rtf 66 | javax.swing.tree 67 | javax.swing.undo 68 | javax.transaction 69 | org.omg.CORBA 70 | org.omg.CORBA_2_3 71 | org.omg.CORBA_2_3.portable 72 | org.omg.CORBA.DynAnyPackage 73 | org.omg.CORBA.ORBPackage 74 | org.omg.CORBA.portable 75 | org.omg.CORBA.TypeCodePackage 76 | org.omg.CosNaming 77 | org.omg.CosNaming.NamingContextPackage 78 | org.omg.SendingContext 79 | org.omg.stub.java.rmi 80 | 81 | -------------------------------------------------------------------------------- /ressources/stylesheet.css: -------------------------------------------------------------------------------- 1 | /* Javadoc style sheet */ 2 | 3 | /* Define colors, fonts and other style attributes here to override the defaults */ 4 | 5 | /* Page background color */ 6 | body { background-color: #FFFFFF } 7 | 8 | /* Headings */ 9 | h1 { font-size: 145% } 10 | 11 | /* Table colors */ 12 | .TableHeadingColor { background: #CCCCFF } /* Dark mauve */ 13 | .TableSubHeadingColor { background: #EEEEFF } /* Light mauve */ 14 | .TableRowColor { background: #EEEEEE } /* Light gray */ 15 | 16 | /* Font used in left-hand frame lists */ 17 | .FrameTitleFont { font-size: 100%;
