问题 I have created a zoom and pan class for an ImageView. Features I am trying to create. - It pans on single finger touch and movement - It zooms and pans on two finger touch and movement For the most part this works very well. It has a slight bug when I do the following: - I pan around with one finger (Status: No problem) - I put down a second finger, zoom and pan (Status: No problem) - I release my second finger (Status: The image jumps a little) Was hoping someone could help me solve this. I

D3.js Zooming and panning a collapsible tree diagram

I'm using D3.js to plot a collapsible tree diagram like in the example . It's working mostly well, but the diagram might change dramatically in size when it enters its normal function (ie instead of the few nodes I have now, I'll have a lot more). I wanted to make the SVG area scroll, I've tried everything I found online to make it work, but with no success. The best I got working was using the d3.behaviour.drag , in which I drag the whole diagram around. It is far from optimal and glitches a lot, but it is kinda usable. Even so, I'm trying to clean it up a little bit and I realised the d3

问题 I want to make a container which can be dragged around, zoom and rotate. I am able to achieve a zoom.

Zooming and Panning a Mercator Map centered on the Pacific using d3.js

由 烂漫一生 提交于 2019-11-27 03:28:50
问题 Apologies if this is a simple case of me being blind to the obvious, but I am trying to put together a page that shows a map of the world (data sourced from a TopoJSON file) in Mercator projection centered on the Pacific. I.e. Europe on the left, America on the right and Australia in the middle. A bit like this... From this point I want to be able to zoom and pan the map to my hearts desire, but when I pan east or west, I want the map to scroll 'around' and not come to the end of the World (I

Zooming and scrolling in SpriteKit

由 独自空忆成欢 提交于 2019-11-26 18:07:28
问题 I am new to SpriteKit. I need to display an image via UIImageView OR SpriteNode (it is a background image for a game). However, I need the user to be able to zoom in to the background and pan around. I accomplished this easily without using SpriteKit but cannot figure out how to make a node accept zoom and pan. If I use UIScrollView in the storyboard, all the sprites added in my scene don't become children and will not zoom or pan. Is it possible and can you point me in the right direction?

Pan & Zoom Image

问题 I want to create a simple image viewer in WPF that will enable the user to: Pan (by mouse dragging the image). Zoom (with a slider). Show overlays (rectangle selection for example). Show original image (with scroll bars if needed). Can you explain how to do it? I didn\'t find a good sample on the web. Should I use ViewBox? Or ImageBrush? Do I need ScrollViewer? 回答1: The way I solved this problem was to place the image within a Border with it's ClipToBounds property set to True. The
