LXFree for Java on Windows stores report templates, color library and key files in the user's %APPDATA%\LXSeries4Windows\LXFreeForJava directory. Fonts vary across operating systems and may change when moving a file from one to another. For compatability across operating systems, imported graphics are stored in JPEG or PNG format in lxxplot files. There are some considerations when moving a file from/to LXBeams/LXFree on MacOS to/from LXFree for Java. LXFree for Java reads and saves ".lxxplot" files. LXFree for Java uses the same LXFoundation technology as LXBeams and LXFree running on MacOS but, it is a separate application. Java is a trademark of Oracle Corporation and/or its affiliates. Java(tm) is a programming language and software platform that allows the same application to run on different operating systems that was originally created by Sun Microsystems. The latest version of LXFree for Java is 2.7.0 (14808.1). LXFree for Java is free to use for non-commercial purposes. LXFree for Java may also work with other versions of Linux or operating systems that support Java. OpenJDK versions of the Java runtime are recommended and an installer is available for Windows that includes a runtime so nothing else is needed. LXFree for Java is currently available for Windows and Linux (Ubuntu/Debian) with Java(tm) 1.8 or later installed. Please help by providing feedback on problems encountered using LXFree for Java. LXFree for Java is still being developed and tested. LXFree for Java produces reports by linking the graphics, attached data, and additional databases related to the properties of these objects. LXFree for Java combines drawing a light plot with editing information attached to graphic objects in the drawing. PLANE.LXFree for Java is an application for drawing light plots and generating paperwork. saves the mouse's position whenever the mouse moves PLANE.widthProperty().addListener(centerContent()) PLANE.heightProperty().addListener(centerContent()) tries to center the CONTENT whenever the window is resized Private Point2D dragOffset = new Point2D(0, 0) Private Point2D lastMousePosition = new Point2D(0, 0) Private Point2D lastContentPosition = new Point2D(0, 0) the plane on which the node is being dragged Here is the class I use to handle the zoom and dragging package If the centering method worked correctly, the square should return to the same position is was at before the window was expanded, which happens when the square is at 1 to 1 scale and no zooming has occured This only happens when scaling has been applied and appear to be a problem with the re-centering method. If you shrink the window, then the square will no longer be at the same place as before. If you run the code I posted and zoom in, then resize the window, you'll notice that the red rectangle representing the image goes all over the place. To achieve this, the idea is to recenter the content whenever the window changes size, and then apply a translation corresponding to the amount of dragging done by the user It would be much more logical for the content to appear to be moving relative to the center. By default any displacement in an Anchorpane is relative to the top-left corner, but that is not intuitive to the user. The idea is that I want to be able to recenter the image when the app resizes so that dragging always appears to be relative to the center of the Anchorpane. The zooming and panning both work individually, but I am having trouble re-centering the image once it has been zoomed in or out. The class contains references to an Anchorpane, which I am using since it does not do any aligning by default, as well as an ImageView which I want to be able to drag and zoom onto. I am trying to create a class which handles zooming and panning components.
