Set maximum size for JavaFX ImageView

问题

I resize the image view according to the scene but image keep resizing even if the scene is bigger than image original size.

I have set ImageView.maxWidth(originalImageWidth) but it did not work.

I resize the ImageView by binding it's size to the the scene size.

回答1:

This would work

Pane root = new VBox(); //or other Pane sub-class
ImageView bg = new ImageView(...);
bg.setPreserveRatio(false);
bg.fitWidthProperty().bind(root.widthProperty());
bg.fitHeightProperty().bind(root.heightProperty());
root.getChildren().addAll(bg);

May not be too relevant anymore but i found a solution that works for me at least:

• set setPreserveRatio to true,
• set fitHeight to the wanted maximum width * ratio
• bind the fitWidthProperty to the screnes widthProperty

In other words: you can bind one dimension and have a maximum fit size to the other at the same time.
