Adding space around images in JavaFX

Just a quick question. I'm wondering if there is a way to apply padding to an ImageView using CSS in JavaFX. I've attempted insets, padding, and other methods with no success.

Alternatively, can the same effect be achieved with a Text Object? I've searched on Google but haven't found much information. It's not a huge issue, just looking for a cleaner solution.

Thank you!

-fx-padding is a characteristic of a Region.

An ImageView does not fall under the Region category, therefore, direct use of padding on an ImageView is not possible. However, you can place the ImageView within a Region to create a padded area around it.

Here's an example that utilizes a StackPane (which is a style-capable region). The padding is defined in FXML, but could also be implemented using CSS.

In this example, the green border surrounding the image represents the padding.

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.geometry.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

<StackPane id="StackPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="-1.0" prefWidth="-1.0" style="-fx-background-color: forestgreen;" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2">
  <children>
    <ImageView fitHeight="150.0" fitWidth="200.0" pickOnBounds="true" preserveRatio="true">
      <image>
        <Image url="http://www.corwellphotography.net/image/2223982.jpeg" />
      </image>
    </ImageView>
  </children>
  <padding>
    <Insets bottom="10.0" left="10.0" right="10.0" top="10.0" />
  </padding>
</StackPane>

Since a StackPane or Region has the ability to contain various types of nodes, this technique can be applied to any kind of node (not limited to ImageViews).
