zooming

I can't get working zoom relative to mouse position in JavaFX. I've read and tried rewrite this and this , but it's not working. Can't scroll viewport using scrollPane.setViewportBounds() . I must use scrollPane.setHvalue() and scrollPane.setVvalue() , but can't get right recalculation to keep the same pixels under the mouse cursor. Current code keeps scrollbars positions: ZoomHandler.java import javafx.event.EventHandler; import javafx.scene.control.ScrollPane; import javafx.scene.input.ScrollEvent; import javafx.scene.layout.Pane; public class ZoomHandler implements EventHandler<ScrollEvent>

I am building a website with a navbar-fixed-top class for the navbar.It works fine on everything except when I zoom in. When I zoom in on a mobile device; the navbar starts wrapping and goes to next line after collapsing. However, I do not want the navbar to be affected when zooming in but at the same time keeping the responsiveness for different devices. Is this possible or is there a work around ? <nav class="navbar navbar-default navbar-static-top lato-reg" id="navMenu"> <div class="container"> <div class="navbar-header page-scroll"> <button type="button" class="navbar-toggle" data-toggle=

When I zoom in and out on my webpage in Google Chrome, items that are precisely positioned in relation to one another will change position. This causes many problems: For example, at specific zoom levels a div will overlap its containing div just enough to hide a border. Similarly, sometimes a 100% marker will not precisely line up with the 100% point. Is there any way I can ensure that the positioning of the items in relation to each other will not change when the page is zoomed in or out? You can use em positioning which will reposition and size based on the font size. So when people do like

I am using VideoView & running videos from resources. I want to know, is there any way by which I can perform zoom in/out functionality on running video? OK I had this issue and solved it by removing the VideoView and replaced it with a TextureView . You can then apply a Matrix transformation which includes lots of options including zooming. The method for the Matrix I would use is the postScale() method. You can apply multiple effects pre and post, which you can view in the documentation. Edit Here is a custom VideoView from a running project that we used. You can decalre it in XML Layouts

In my application, i'm using the following code for holding a map which is downloaded from a server. <?xml version="1.0" encoding="utf-8"?> <ScrollView android:id="@+id/scrollView1" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_gravity="center" android:layout_weight="1.0"> <ImageView android:id="@+id/mapImageView" android:layout_height="wrap_content" android:layout_centerInParent="true" android:layout_width="wrap_content" android:scaleType="center"/> </ScrollView> currently, i can scroll the image up and down only. I need to have the ability to scroll

If anyone came across the google maps app for iOS there is a great feature to zoom in/out with one finger: Doubletap on the uiscrollview and then immediately slide finger up or down to zoom in/out. Does anyone know how this is achieved? Did google post any snippet of that? I added this functionality to my UIScrollView category . The actual tap recognition is easy, calculating the "correct" (whatever feels "correct") zoomScale is the problem… If you think the category isn't handling this good enough, please don't hesitate to tell me and open a new issue on the github page.
