Algorithm for self-scaling ruler in plotter GUI component

由 隐身守侯 提交于 2019-12-04 13:59:44
I am designing (not programming) a data-series viewer program for medical data, using C#/WPF. There is one main panel which shows the data, with the common mouse pan/zoom functionality (pan with left drag, horizontal zoom with scroll, vertical auto-fit with double click, selection with right drag). The problem is: I need vertical and horizontal grid with rulers on the top/left, similar to those seen in audio-editing (goldwave, audacity), cartography (gpsTrackmaker) and ilustration (photoshop, inkscape) programs. Besides, these rulers are even configurable in most plotting APIs (Matlab, GNUPlot

How to zoom to the center with a scrollview?

由 霸气de小男生 提交于 2019-12-03 22:17:30
We had previously implemented tapping to zoom and now we've decided to use icons instead that will zoom in on the center of whats currently being displayed, and we'd like to reuse the code we had for our tap to zoom since we want the same effect, but now we don't know what to pass as the centerpoint. We're using the (CGRect)zoomRectForScale:(float)scale withCenter:(CGPoint)center method which used to accept a center cgpoint from the gesture recognizer that we used for tap zooming; however, since we're no longer using the gesture recognizer we're going to have to figure out what cgpoint to pass

How do I stop a CSS layout from distorting when zooming in/out?

问题 I've set up a very basic site with a #container div that includes the #navbar and #content. However, when I zoom in or out, the #navbar distorts, if I zoom in the links get pushed down below each other instead of being inline. If I zoom out, too much padding is added between the links. How can I stop this? HTML: <div id="navbar"> <ul> <li><a href="index.html">Home</a></li> <li><a href="top.html">Top</a></li> <li><strong><a href="free.html">FREE</a></strong></li> <li><a href="photo.html">Photo

Turn off Zooming in UIScrollView

由 笑着哭i 提交于 2019-12-03 10:26:06
Does anyone know a way to temporarily turn off zooming when using a UIScrollView? I see that you can disable scrolling using the following: self.scrollView.scrollEnabled = false; but I'm not seeing a similar command for zooming. Any thoughts? combinatorial If you want to disable the user's ability to zoom through gestures then in iOS 5 and above you can disable the pinch gesture. This still allows you to control the scroll view from code... scrollView.pinchGestureRecognizer.enabled = NO; similarly for pan... scrollView.panGestureRecognizer.enabled = NO; This must be called in - (void

How do I suppress window mouse wheel scrolling…?

由 十年热恋 提交于 2019-12-03 06:57:39
I'm working on a canvas app embedded in a page. I have it so you can zoom into the drawing with the mousewheel but unfortunately this scrolls the page as it is part of an article. Is it possible to prevent mousewheel scrolling on the window when I'm mousewheeling on a dom element?! Attach an event handler for mousewheel (Not Gecko) / DOMMouseScroll (Not IE) and prevent its default action (that is to scroll content): if (element.addEventListener) element.addEventListener("DOMMouseScroll", function(event) { event.preventDefault(); }, false); else element.attachEvent("mousewheel", function() {

emacs zoom in/out globally

由 我与影子孤独终老i 提交于 2019-12-03 02:42:42
I know that I can zoom in/out using C-x C-+, but this applies only to the current file. Once I open another one, the text goes back to the default value and it's really tiresome to do it over and over. How can I keep the zoom level global for the current emacs session? I know it's possible to set this in the init file if you know the exact font size, which I don't. Plus, I don't want to keep it that permanent - I usually need this when I'm without an external screen for a couple of hours or connected to a beamer while giving a presentation. This piece of code modify the zoom in/out

zoom in/out images in c#

问题 Any one know the corresponding C# code of this 回答1: Yes, I do. Are you asking for someone on here to translate that entire VB.NET project into C# for you? That isn't likely to happen for free. Instead, might I suggest that you try an automated conversion tool, like this one, or this other one? But really, any competent C# programmer should be able to translate VB.NET code into C# with a little bit of effort. The only thing that's changed is the syntax; the underlying methods are all exactly
