Get width and height of resized imageView

The post "Get width and height of javafx.scene.image.Image" demonstrate how to get width and height of Image by calling Image's getWidth() and getHeight() methods. Another post "Set fitWidth and fitHeight properties dynamically" demonstrate how to set ImageView auto-fit by calling ImageView's setFitWidth() and setFitHeight(). After auto-fited, we cannot get width and height by calling Image's getWidth() and getHeight() methods. Both of them return the original values, not the scaled values.

javafx.scene.image.ImageView provide getBoundsInLocal() and getBoundsInParent() methods to return the rectangular bounds of this Node.

• getBoundsInLocal(): Gets the value of the property boundsInLocal.
  
  The rectangular bounds of this Node in the node's untransformed local coordinate space. For nodes that extend Shape, the local bounds will also include space required for a non-zero stroke that may fall outside the shape's geometry that is defined by position and size attributes. The local bounds will also include any clipping set with clip as well as effects set with effect.
  
  
• getBoundsInParent(): Gets the value of the property boundsInParent.
  
  The rectangular bounds of this Node which include its transforms. boundsInParent is calculated by taking the local bounds (defined by boundsInLocal) and applying the transform created by setting the following additional variables:
  - transforms ObservableList
  - scaleX, scaleY
  - rotate
  - layoutX, layoutY
  - translateX, translateY
  
  

Via the rectangular bounds, we can get the re-sized width and height by calling getWidth() and get Height() methods.

Apply SepiaTone on ImageView

javafx.scene.effect.SepiaTone is a filter that produces a sepia tone effect, similar to antique photographs. To apply SepiaTone on a ImageView, simple call setEffect(new SepiaTone()) method of ImageView.

Set fitWidth and fitHeight properties dynamically

The article "Auto fit JavaFX 2 ImageView" demonstrate how to set ImageView auto-fix by setting fitWidth and fitHeight properties. To remove the auto-fix function, we can call setFitWidth() and setFitHeight(), then the intrinsic height of the image will be used as the fitHeight. Such that we can set/remove auto-fix at run-time.

bind widthProperty and heightProperty of Image

The former article described how to "Get width and height of a Image" by calling getWidth() and getHeight() methods. Alternative, we can bind the textProperty of label with widthProperty and heightProperty of Image. Please notice that image cannot be null in this case, otherwise java.lang.NullPointerException will be thrown.

Caused by: javafx.fxml.LoadException: ... is not a valid type.

It's a tips to include custom control(UI element) in FXML.

It's the FXML from the example "Embed WebView in FXML, to load OpenLayers with OpenStreetMap".

<?xml version="1.0" encoding="UTF-8"?>
 
<?import java.lang.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

        <MyBrowser id="mybrowser" layoutX="10" layoutY="10" prefHeight="460" prefWidth="620" fx:id="mybrowser" />
    </children>
</AnchorPane>

Where MyBrowser is a custom class defined in my package, javafxml_web. So, the statement <?import javafxml_web.*?> have to be added. Otherwise error will be reported, Caused by: javafx.fxml.LoadException: MyBrowser is not a valid type.

And also state the solution of udating Java 7 Update 11:

Solution

Update Java

Oracle Security Alert CVE-2013-0422 states that Java 7 Update 11 (7u11) addresses this (CVE-2013-0422) and a different but equally severe vulnerability (CVE-2012-3174). Java 7 Update 11 sets the default Java security settings to "High" so that users will be prompted before running unsigned or self-signed Java applets.

How to run Java Control Panel on Windows 8

To run Java Control Panel on Windows 8, search java in Settings.

Set PATH to JDK on Windows 8 (official version)

Last post described how to "Download and Install JDK 7 on Windows 8 (Official version)".

After downloaded and install JDK 7 on Windows 8, now open a Command Prompt window to run java or javac...!!!

you can optionally set PATH environment variable to JDK so that you can conveniently run the JDK executable files (javac.exe, java.exe, javadoc.exe, and so forth) from any directory without having to type the full path of the command.

To set path, search "Environment Variables" in "Settings", click "Edit the system environment variables".

Click "Environment Variables".

Select System variables of Path, and click Edit...

Add the location of the bin folder of the JDK installation, in my case it is "D:\Program Files\Java\jdk1.7.0_11\bin".

Now, you can close and re-open Command Prompt window, type java and javac to varify your setting.

Install JDK 7 on Windows 8 (Official version)

In this post, I describe how to download and install JDK 7 (Java SE 7u11 currently) on official Windows 8 (not Preview version).

Note: You must have administrative permissions in order to install the JDK on Microsoft Windows.
Note: Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory.

Visit http://www.oracle.com/technetwork/java/javase/downloads/index.html, click the download Java Platform button.

Scroll down to check Accept License Agreement, select Java SE Development Kit 7u11, jdk-7u11-windows-i586.exe for Windows x86.

Run the downloaded installer.

Select optional features and location to install.

Select location to install jre.

Completed.

Install JDK 7 and update-alternatives on Ubuntu 12.10

Download update JDK here: http://www.oracle.com/technetwork/java/javase/downloads/index.html, click the DOWNLOAD Java Platform graph.

Scroll download to check the box of Accept License Agreement, and select the package to download. In this case, jdk-7u11-linux-i586.tar.gz for Linux x86 is selected.

Move the downloaded .tar.gz archive binary to the directory you want to install.

Open a Terminal, the the command to unpack the tarball and install the JDK:
$tar zxvf jdk-7u11-linux-i586.tar.gz

For example, if you download the .tar.gz is /home/you, your installed directory will be /home/you/jdk1.7.0_11.

Then, you have to update alternatives for javac and java:
$sudo update-alternatives --install /usr/bin/javac javac /home/you/jdk1.7.0_11/bin/javac 1
$sudo update-alternatives --install /usr/bin/java java /home/you/jdk1.7.0_11/bin/java 1

If you have more than one javac installed, you have to config your javac alternative
$sudo update-alternatives --config javac
$sudo update-alternatives --config java

Finally, delete the downloaded .tar.gz after then.
