I was recently looking at the Tesseract module to convert handwritten text into typed text, however I was wondering is there anything out there, or any code which would allow me to do it the other way? I would like to load up a piece of typed up text (pdf, word, even notepad), and be able to turn it into an object for manipulation.
In the long run, I'd like to be able to open up a pdf document, click on some text, edit it, then use tesseract to turn it back into typed text.
I'm having an issue with my program that needs 2 lines of input when I only want one. First I call Scan.nextLine(); to fetch a word. Then I want Scan.findInLine(word).charAt(number); to scan the string word for a letter instead of having to put another line in the console. How do I make Scan.findInLine(word).charAt(number); scan a single String instead of scanning input typed by the user?
I have a JTable with 5 columns, named: "ID", "Name", "UnitPrice", "Qty", and "Total". Only the columns UnitPrice and Qty are editable by the user. When, for example, for a row in the JTable, the user types 5000 in the UnitPrice column, and types 15 in the Qty column, I would want that when he types the first character in the Qty column (i.e. the character 1) in the Qty column, the Total column displays 5000*1, in other terms 5000.
And when the user types the second character in the Qty column, i.e the character 5, after having typed 1, the Total column should display 5000*15, in other terms 75000. So, to say it concisely, I would want that the Total column refreshes accordingly each time the user types a character in the Qty column. I have tried to use the MouseClicked event of the JTable, but noticed that that does not solve my problem. is there an event I should use to refresh my Total column? Or should I proceed in another fashion?

I am trying to get it to compare the word I type in to the set word in the object 'secretword'. I have tried everything from equal to == to compareTo, I even created a two hundred line program to do this SIMPLE problem.
I am developing JavaFX application. I have requirement like that javafx application should be always on top. I could not find an option to make it always on top.
I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?
I am using netbeans scenebuilder and I am a little confused on how I would convert my state capitals java code to a javaFX app.
public class StateCapitals { Scanner in; public static void main(String[] args) { readData(); } public static void readData() { // Location of file to read File file = new File("statecapitals.txt");
I've been on this for a while and for some reason I just can't seem to get this to work. I know my code is solid, but it won't display my image. I've tried swithcing the image to different directories and also using different image sizes and types. I even used Orcale's guide to display your image, but still no go! All I get is a blank canvas? There are no errors. I'm also running NetbeansIDE 8 that supports JavaFX and I made sure the project is a JavaFX Application project.
The homework called for me to display it three times - the first one regular, second resized, and the last one rotated. I even deleted the extra images in hope at least one appears.
I'm working on a project right now in JavaFX, and got stuck. I am drawing a path consisting of CubicCurveTo's and I wonder if there's any way to get the X and Y coordinates from certain parts of that path.
Imagine following a curve (path) with a pencil slowly, and every second you take note the X and Y coordinate. I mean I'm not interested in the control points or start and end points, but the points "in between", preferably at a certain interval.
I've searched for many things online, but have trouble knowing exactly which words to search for. "Paths" often bring up file paths, traversing, coordinates etc. all fail to give me any good results.
I tried to be as specific I could, and I don't think my current code is of any interest in this matter.
(The point of it all is that the path should simulate the path a person walks, and I will store the coordinates in a database for every second).
When i press a button, i want to create a new object in my window(that i have created using scenbuilder, so i have a FXML file and a Controller class). In the window where i have a create button, there are also some textfields where you are supposed to enter name and date.
What i want to do is take the input from the TextField and store is temporally in a String variable, Its this strings i want to take the data from when i create a new object on my View. When i try to do something with the TextFields i get multiple errors that i dont understand at all.
I know my code may be very un-structured the absolute right way, i know, but i dont have time reconstructing and trying to understanding new patterns .The object is the circle and the vertical line.
TimelineMainView Controller public class TimelineController{ StageClass sc = new StageClass(); NewTimelineController nt = new NewTimelineController();
I'm quite new to JavaFX, and currently struggling with navigation between views. I'll post the code and the stacktrace.

How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?
I am new to JavaFX and OpenCV. The Problem is, that JavaFX can't handle Mat objects. First I load an image as a BufferedImage. Then i have to convert this to Mat. Do my image Processing with OpenCV and again convert the result image to a BufferedImage to display in on my UI. Here are the methods for converting Buff to Mat and Mat to Buff I found on the internet:
public static Mat img2Mat(BufferedImage image) { byte[] data = ((DataBufferByte) image.getRaster().getDataBuffer()).getData(); Mat mat = new Mat(image.getHeight(), image.getWidth(), CvType.CV_8UC3); mat.put(0, 0, data); return mat;
[Code] ....
Next I do some OpenCV stuff:
public static BufferedImage hello(BufferedImage img) { Mat source = img2Mat(img); //Convert Buff to Mat BufferedImage outImg = null; try{ System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
[Code] ....
Finally I call the hello method in my controller:
void menuItemTestFired(ActionEvent event) { try { result = ImageProc.hallo(bImage);//bImage is an image I've loaded before. imageView.setImage(SwingFXUtils.toFXImage(result, null));
[Code] .....
Unfortunately I get a lot of errors. Here are the first one:
Caused by: java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J at org.opencv.core.Mat.n_Mat(Native Method) at org.opencv.core.Mat.<init>(Mat.java:471)
I'm using WebView to display an OpenLayers3 map, e.g. Animation example from openlayers.org. When I lock my screen and unlock it, none of the openlayers layers are re-drawn. Sometimes bringing the window in to focus or a small resize of the component will cause the map to go blank. This doesn't occur in any browser I've tested, so it seems to be a WebView specific issue, although it also seems to be layer specific and possibly cache related. I've only tested on Windows, 1.7.0_51 x64 and 1.8.0_05 x64 ....
There are a few things lacking in the TableView's keyboard navigation handlers. In tracing the code, the behavior is handled via TableViewBehavior and its super classes. If I want to augment that behavior, how do I do it?
Ideally, I would like to subclass TableViewBehavior, but I don't see how I can do it. This gets created in the TableViewSkin ctor:
public TableViewSkin(final TableView<T> tableView) { super(tableView, new TableViewBehavior<T>(tableView)); ... }
but as you can see there is no factory method to create the behavior class. If there was, I could subclass TableViewSkin and override the factory method.
At the end I just copy and paste the code from section 9.3.4 (the long startup task example) and it still won't work. After starting the application I only see some black screen flickering at the upper left screen and then the main app shows up.
What I have done:
Using Netbeans 8.0 under Linux(Fedora20 64bit), JDK 1.8u5 ...
On my machine I see only a little black flickering on the left upper screen and then immediately the app is shown...
The only way I can get this to run is to set the custom preloader property in the Netbeans-project properties. If you use a maven based project in Netbeans you did not got this option ...
With JSP can do? How do it? or exist other way? or: [URL] ....
I tested (i need some configuration): [URL] .... but this method download the jar file (and other libraries) right? and the program act same as a Desktop app, right?
I'm trying to play an encrypted HLS video using MediaView and MediaPlayer is throwing a "can't create player" exception. Searching for a solution all I found was this post from january last year, saying it is not supported and to add a feature request. I looked in the JDK bug system for HLS/live streaming and didn't saw anything related. Is this still not working on the latest JavaFX?
