imageview

问题 I thought this would be a simple question but I am having trouble finding an answer. I have a single ImageView object associated with a JavaFX Scene object and I want to load large images in from disk and display them in sequence one after another using the ImageView. I have been trying to find a good way to repeatedly check the Image object and when it is done loading in the background set it to the ImageView and then start loading a new Image object. The code I have come up with (below)

问题 So I've got transparant buttons with white text labels set up over a user uploaded ImageView . If the user uploads an image that is mostly white, then the buttons are hard to see if not completely invisible. Does anyone know of a way to get the average color of a ImageView 's source picture/drawable? If I can do this, I can compare it to a certain threshold I can trial and error for... If I can get this, then I can change the color of the text on my buttons to the inverted version of this

问题 I'm trying to fit an ImageView in an AnchorPane, the ImageView is obtained from a database, so no CSS, I tried binding the width and height of the ImageView withe the width and height of the AnchorPane, but I get this result: Here's my fxml: <?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.control.Label?> <?import javafx.scene.image.ImageView?> <?import javafx.scene.layout.AnchorPane?> <?import javafx.scene.text.Font?> <AnchorPane maxHeight="-Infinity" maxWidth="-Infinity"
