How can I capture which direction is being panned using UIPanGestureRecognizer?

和自甴很熟 提交于 2019-12-04 07:39:52
问题 Ok so I have been looking around at just about every option under the sun for capturing multi-touch gestures, and I have finally come full circle and am back at the UIPanGestureRecognizer. The functionality I want is really quite simple. I have setup a two finger pan gesture, and I want to be able to shuffle through some images depending on how many pixels I move. I have all that worked out okay, but I want to be able to capture if the pan gesture is REVERSED. Is there a built in way that I'm

google maps pan to

Been struggling all day with setting a pan to in google maps from a text link. It looks like the id of the map itself isnt being passed through to the function but I have tried a number of things with no joy. <script type="text/javascript"> var home = new google.maps.LatLng(4.915833, 10.195313); function initialize() { var myOptions = { zoom: 2, center: home, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControl: false, panControl: true, panControlOptions: { position: google.maps.ControlPosition.LEFT_CENTER }, zoomControl: true, zoomControlOptions: { style: google.maps.ZoomControlStyle

I'm creating quite a cool image viewer but am stuck in one particular part: panning the image when zoomed in. It seems a trivial problem and I've tried out pretty much all answers to similar questions on SO, but each time, something isn't working right. I need a fresh pair of eyes. I've temporarily opened a URL on my dev server. Have a look at this page: [URL closed] Next, move up your mouse wheel to trigger the zoom. Here we are. Once zoomed in, click and drag to try and pan the image. It is panning alright, but something isn't right. This is currently the code used for the panning: var

Move HTML5 Canvas with a background image

I want to visualize a huge diagram that is drawn in a HTML5 canvas. As depicted below, let’s imagine the world map, it’s impossible to visualize it all at the same time with a “decent” detail. Therefore, in my canvas I would like to be able to pan over it using the mouse to see the other countries that are not visible. Does anyone know how to implement this sort of panning in a HTML5 canvas? Another feature would be the zoom in and out. I've seen a few examples but I couldn't get them working nor they seam to address my question. Thanks in advance! To achieve a panning functionality with a

Pan/zoom ordinal scale?

Deadly 提交于 2019-12-03 12:59:50
问题 I am using d3 to render a simplified gantt chart, with panning and zooming using d3.behavior.zoom. The x scale is a time scale (slightly modified to center calendar days in columns, etc) and works beatifully, but I'm having problems deciding how to zoom/pan the y scale, whose domain is a list of tasks which will often be too many to fit in the chart area, so the need for panning/zooming. Is there a way to tell the default ordinal scale to react to zoom/pan events, or should I write a custom

D3 force layout: making pan on drag (zoom) smoother

元气小坏坏 提交于 2019-12-03 12:43:50
I've got a d3.js static force layout graph that can get rather big (sometimes parts of it are clipped), so I'd like to let the user pan the whole graph by dragging. I don't think I need dragging of individual nodes, I've got a feeling that's just going to be confusing, but would like to make it possible to show the parts of the graph that are clipped by the svg boundaries. I've got a minimal example at http://bl.ocks.org/3811811 which uses visF.append("rect") .attr("class", "background") .attr("width", width) .attr("height", height) .call(d3.behavior.zoom().on("zoom", redrawVisF)); function

How do I get my D3 map to zoom to a location?

巧了我就是萌 提交于 2019-12-03 07:56:47
问题 I'm working with D3 and so far I've been able to tweak the chloropleth example to only draw a specific state. This involved simply removing all the other polygon data so that I'm left with the state I need. I started with this: and then tweaked things to this: However, what I'd like to do is to auto pan/zoom the map upon creation so that the state is front and center on the display, like this: Do I do this through the D3 library? or some independent code (I currently have jquery-svgpan
