j-graphic-tools (jgt) is a easy to use Java-API and a collection of usefull tools for graphic manipulation. It is released under a Apache-styled license. At the moment only jpg images are supported, other graphic formats will follow. jgt includes the following tools/libs: JThumbnailer: Creates a html page with thumbnails of your images ImageResizer: Resize graphics (tool and Api) jgt uses the JIMI-API from Sun (http://java.sun.com/products/jimi). JThumbnailer JThumbnailer is a commandline tool. You can start it with the following command:     java org.juniverse.jgraphictools.JThumbnailer <path_to_properties_file> Make sure that jgraphictools.jar and jimiproclasses.jar are in your classpath! In the specified properties file, you need to include the following attributes: SOURCE_DIR: the place where your original images are stored (they will not be modified) TARGET_DIR: the directory, where the html file and the thumbnails will be saved THUMBNAIL_DIR: the subdirectory for the thumbnails HTML_TEMPLATE: the name of the html template that will be used TABLE_HEADER: the header of the table, in which the thumbnails will be displayed TABLE_FOOTER: the footer of the table, in which the thumbnails will be displayed IMAGE_TAG: the string, that will be replaced by the image table TABLE_COLS: the number of columns in the table TARGET_WIDTH: the width of the thumbnails TARGET_HEIGHT: the height of the thumbnails You can find an example for an properties file here. Please not that you have to use a slash / instead of an backslash \ for any path (yes, on windows too). You can setup the layout of your html page with every tool you like. Simple insert an tag like <images/> on that location in your page, where the thumbnails should be insert. Specifiy the tag in the IMAGE_TAG property. If you specify only one of the values TARGET_WIDTH and TARGET_HEIGHT, the other one will be computed by the JThumbnailer (set the second parameter simple to -1). ^ top ImageResizer As Java-API you can use the ImageResizer like this: If you like to resize a single graphic: import org.juniverse.jgraphictools.ImageResizer; ImageResizer.resize("C:/source.jpg", "C:/target.jpg", 800, 600); If you like to resize all graphics in an directory: import org.juniverse.jgraphictools.ImageResizer; ImageResizer ir = new ImageResizer(); ir.setSourceDir("C:/source"); ir.setTargetDir("C:/target"); ir.setTargetWidth(640); ir.setTargetHeight(480); ir.resize(); As commandline tool, you use it like the JThumbnailer:     java org.juniverse.jgraphictools.ImageResizer <path_to_properties_file> Make sure that jgraphictools.jar and jimiproclasses.jar are in your classpath! In the specified properties file, you need to include the following attributes: SOURCE_DIR: the place where your original images are stored (they will not be modified) TARGET_DIR: the directory, where the html file and the thumbnails will be saved TARGET_WIDTH: the width of the thumbnails TARGET_HEIGHT: the height of the thumbnails Please not that you have to use a slash / instead of an backslash \ for any path (yes, on windows too). If you specify only one of the values TARGET_WIDTH and TARGET_HEIGHT, the other one will be computed by the ImageResizer (set the second parameter simple to -1). ^ top Feedback Any feedback is welcome!
