I created a sample app to demonstrate one approach to performing scaling of a node in a viewport on a scroll event (e.g. scroll in and out by rolling the mouse wheel). The key logic to the sample for scaling a group placed within a StackPane: final double SCALE_DELTA = 1.1; final StackPane zoomPane = … Read more
May not be answer for this specific question, but if someone is, like me, searching for answer how to fit image in ImageView with bounded size (for example, maxWidth) while preserving Aspect Ratio and then get rid of excessive space occupied by ImageView, then the simplest solution is to use the following properties in XML: … Read more
You can use the Axes.set_yscale method. That allows you to change the scale after the Axes object is created. That would also allow you to build a control to let the user pick the scale if you needed to. The relevant line to add is: ax.set_yscale(‘log’) You can use ‘linear’ to switch back to a … Read more
Switch from use of UIGraphicsBeginImageContext to UIGraphicsBeginImageContextWithOptions (as documented on this page). Pass 0.0 for scale (the third argument) and you’ll get a context with a scale factor equal to that of the screen. UIGraphicsBeginImageContext uses a fixed scale factor of 1.0, so you’re actually getting exactly the same image on an iPhone 4 as … Read more
this is a working example of two fingers move/scale/rotate (note: the code is quite short due to smart detector used – see MatrixGestureDetector): class ViewPort extends View { List<Layer> layers = new LinkedList<Layer>(); int[] ids = {R.drawable.layer0, R.drawable.layer1, R.drawable.layer2}; public ViewPort(Context context) { super(context); Resources res = getResources(); for (int i = 0; i < … Read more
