JavaFX Will Not Display Image
Oct 21, 2014
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.
All I get is a blank new window, but no images.
Here's my code:
package javafxapplication3;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.image.Image;
[code]....
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 have a WebView and a Javascript that appends an <img> tag in a webview.
Like so:
function insertImg(src) {
$("body").append("<img src='" + src + "'/>");
}
I call this function with the following code:
String path = "file://Users/rod/Desktop/123.gif";
webengine.executeScript("insertImg('" + path + "')");
However, this does not work and no image is displayed.
How can this be achieved?

I'm using Scene Builder 2.0 and have added an ImageView to the parent AnchorPane. I've added my PNG files for the app icon and the various buttons. I select the ImageView in Scene Builder and then crawl the filesystem to the project package folder and select the PNG for the Image. The assigned image is displayed in the Imageview in Scene Builder in both design mode and Preview mode.
While everything else shows up properly when the app is executed, the image assigned to the ImageView does not display.
From the FXML file:
<ImageView fx:id="ivBRULogo" fitHeight="64.0" fitWidth="64.0" layoutX="14.0" layoutY="14.0" pickOnBounds="true" preserveRatio="true" AnchorPane.leftAnchor="14.0" AnchorPane.topAnchor="14.0">
<image>
<Image url="@BRU_PE_B_64.png" />
</image>
</ImageView>
What might be occurring between the compiled app and what Scene Builder generates?

If you look at line 74 you will see my actionPerformed method where I want to switch the icon displayed on the JButton. I know I still have to add the images to the button however I am running into a few issues here.
In my next class it will be vital that I can decipher what each icon is display on the JButton.
Java Code: import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class Screen implements ActionListener
[code]....

I have a class that retrieves an image, and a class that is a game. I want to put my image onto the game to use it as the main figure. As of right now in eclipse, the game class runs, so the game works, but the image doesn't do anything. Need to put the image into the game? Here is my image class:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.*;

I am fairly new to Java. I am trying to learn some image manipulation basics. I have searched the web endlessly and made numerous attempts but I cannot seem to get a darn image to display. This code is my latest attempt in Eclipse. The file I am using is chairangle.jpg which is is the src folder of the package I am working in in Eclipse. I am on Windows 8.
import java.awt.*;
import javax.swing.*;
import javax.swing.ImageIcon;
public class otherimg extends JFrame
{
public static void main(String args[]){
JFrame f = new JFrame();
ImageIcon image = new ImageIcon("image/chairangle.jpg");
JLabel label = new JLabel("", image, JLabel.CENTER);
JPanel panel = new JPanel(new BorderLayout());
panel.add( label, BorderLayout.CENTER );
f.pack();
f.setVisible(true);
}
}

My JavaFX code like this:
WritableImage image = scene.snapshot(null);
File outputFile = new File("C:PSBJavaFXApplication1src est0.jpg");
ImageIO.write(SwingFXUtils.fromFXImage(image, null), "jpg", outputFile);
When open this jpg, its background is in orange color. For png type, it works great.

I have an image (16x16 icon). I want to put a superscript 10 on it -- so a 10 above and to the right.
I can probably do this with a TextFlow node, but that seems very heavy for such a simple thing.
Is there some simpler way to do this?
The 10 isn't a fixed constant (so I can't just edit my image).

I am writing a piece of software to display an image on the screen using a particular library. The library lets me create an Atlas out of texture file data, to fetch Textures out of the Atlas using the textures' names, and to draw the textures by calling Renderer.draw(texture). It doesn't make a great deal of sense to create more than one of an Atlas or Renderer. I previously designed my code as follows:
public class SystemAssets {
static Atlas atlas;
public static void initializeAtlas(String pathToTextureFiles) {
atlas = new Atlas(pathToTextureFiles);
}
public static Texture getTexture(String textureName) {
return atlas.getTexture(textureName);
}
}
Similarly, I made a TextureRenderer class whose sole purpose is to provide static access to a Renderer. But many people seem to say that opening up a class like this to global access is bad. I cannot think of any better alternative, however. My core update/draw logic currently works something like this:
public class Game extends AbstractGame {
public void init() {
Screen current = new FirstScreen();
TextureRenderer.initialize();
[code]...
Making a Renderer object belong to the Game or Screen class doesn't make much sense to me, as there doesn't seem to really be a 'has-a' relationship between them; it's more of a 'uses-a', so that seems to imply that it would be best to just call Renderer.draw(thing) from outside the class rather than making it a data member. This would make my main code essentially call the various methods in order to get or print some form of data, much like System.out.println(). And of course, making one of the classes a subclass of Renderer makes even less sense. But making data members static for the purpose of global access and using singletons are often cited as 'bad' programming practices. This problem also arises in a lot of other scenarios in my program, ie. when I want to serialize Thing data members like texture filenames; do I put the serializer as a static data member in a class for global access and call it like I would a function, or do I put it in a class? And it seems like the Renderer will have to be initialized at the start of the program, which would take place in the init() method in Game, then be used to draw Textures in the Screen, so it would have to be accessible from both locations.
edit: In case it's suggested to put these in the main class, that's unfortunately going to be difficult without using static variables; the library recommends having the main class creating an Application object, which is essentially a black box that actually does all the work of calling Game's init() and draw() methods (via a Game object passed into its constructor) and looping until the program exits. AbstractGame and Screen are classes supplied by the library, so it doesn't seem like I can easily give Game any data that AbstractGame doesn't specifically ask for.

I would like to reopen the following discussion: Show SVG-Image in WebView (JavaFX 8)
In our IDE (Eclipse Luna) running with jdk1.8.0_25 we load a html page into the webengine. The html page contains <img> tags with '.png' and '.svg' as src. Everything looks fine.
But if we execute the programm with java -jar, the WebEngine doesn't display the svg-files. Instead it shows the 'File not find'-Icon. The .png files still work
The files are definitly included into the jar and will be displayed if we link to them via <a href="someSvg.svg"></a>
So why it doesn't work.

I created an ImageView with an image with transparent portions. I also did some scaling and moving, which I though might cause this effect, but that is not the case. When I click on the transparent portion of the image the onMouseClick event is not fired. Other mouse events (mouse enter, mouse move, mouse exit, ...) get fired. Only when I click on the non transparent part the click event is fired.
Image img = new Image(getClass().getResourceAsStream("barrel_icon.png"));
ImageView view = new ImageView(img);
view.setScaleX(0.5);
view.setScaleY(0.5);
view.setOnMouseClicked(new EventHandler<MouseEvent>() {
[Code] ....
The area between the barrel and the shadow belongs clearly to the image, however is transparent. I am wondering if there is a reason for this behaviour and what is the best way to work around this issue, as my image has large transparent portions and the non transparent parts are hard to click on. By the way this is all based on JavaFX 2.2.

I'd like to draw an overlay on an image. The overlay is also an image with a black background and a white foreground. Now the white pixels should be drawn on the image in red. This is possible with the code I posted below. However, the problem arises when rotating the stencil (overlay). I get some interpolation errors from the rotation on the boundaries. I tried to clip them with setClip(), but this turns the background from transparent to white. How to remove those spots? Or maybe a completely other idea of achieving an overlay on the image? I'm aware of the pixelreader and iterating through the stencils pixels and draw the respective pixels as rectangles on a Canvas' graphicContext. However, this was extremely slow, compared to the code I posted below (although it doesn't work with rotations).
Here I surrounded the errors:
The image:
The stencil:
And here is the code:
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.*;
import javafx.scene.effect.BlendMode;
import javafx.scene.image.*;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
[Code] .....

I am building an application that shows tables with large amounts of data containing columns that should display a thumbnail. However, this thumbnail is supposed to be loaded in the background lazily, when a row becomes visible because it is computationally too expensive to to this when the model data is loaded and typically not necessary to retrieve the thumbnail for all data that is in the table.
I have done the exact same thing in the past in a Swing application by doing this:
Whenever the model has changed or the vertical scrollbar has moved:
- Render a placeholder image in the custom cell renderer for this JTable if no image is available in the model object representing the corresponding row
- Compute the visible rows by using getVisibleRect and rowAtPoint methods in JTable
- Start a background thread that retrieves the image for the given rows and sets the resulting BufferedImage in a custom Model Object that was used in the TableModel (if not already there because of an earlier run)
- Fire a corresponding model change event in the EDT whenever an image has been retrieved in the background thread so the row is rendered again
Btw. the field in the model class holding the BufferedImage was a weak reference in this case so the memory can be reclaimed as needed by the application.
What is the best way to achieve this behaviour using a JFX TableView? I have so far failed to find anything in the API to retrieve the visible items/rows. Is there a completely different approach available/required that uses the Cell API? I fail to see it so far.

Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
