coordinates

问题 If for example, I have the following coordinates with corresponding colors which represent a hexagonal shaped grid of hexagons: coord = [[0,0,0],[0,1,-1],[-1,1,0],[-1,0,1],[0,-1,1],[1,-1,0],[1,0,-1]] colors = [["Green"],["Blue"],["Green"],["Green"],["Red"],["Green"],["Green"]] How can one plot this in Python so that the points on the plot retain that hexagonal shape? Additionally how can one represent the 'colors' list on the hexagon. Somewhat like this: Simple Hexagonal grid But the look

问题 I am writing a BHO object for IE. I want the screen position of the top-left of the web-page. How can i get this position? The topleft of the first element in DOM returns (0,0). The webBrowser.Left or Top returns the position of the browser but not the top-left of the page. I am using IWebBrowser2. Thanks a million, -anony. 回答1: You may have already figured this out, but using ClientToScreen function might help you. 回答2: I solved the problem myself. The IHTMLElement2.getBoundingClientRect()

问题 some of you know how fill a quads in 2D using barycentric coordinates?At the present, I'm splitting the quads into 2 triangles, but that way is inefficient because I have to iterate over the second bounding box which repeats pixel that were filled previously (by example, to fill the 2nd triangle I traversed the 1st triangle that belongs at bounding box formed by 2nd triangle) Thanks esmitt 回答1: Here is a python example that should be what you're looking for. As you probably know there are no

问题 I am developing a web application using JQuery Framework and am using Geolocation to determine the locations of our hardware stations to display on Google Maps. In our database the locations of the sites are stored in Southing/Easting format. I need a way to convert Southing/Easting coordinates to Latitude/Longitude that Google Maps can understand. Can anyone please tell me the formula or the best way to approach this problem? I have done searches on Southing/Easting however nothing came up,

问题 I am trying to create a Tabla drum app (a Table is a pair of small hand drums attached together). To do this I want to use a button for each section of the drum by putting one on top of another. Like so: I've tried using a circular image for the button but the surrounding area are a rectangle. That means when the user would hit parts of the green circle it plays the sound for the orange circle (I hope that makes sense). How can I ensure the sound for the green pad is played when the user taps

问题 Disclaimer: Any API is NO OPTION for me because of the vast amounts of places I want to process. I know there are plenty of services out there but I'd like to have my own solution Ok, after this is said here my question :) There are platforms like OpenStreetMap and maybe others who are doing very well in bringing the world of maps into the open source community. What I need I have an address located anywhere in the world and I want to compute the latitude and longitude, elevation would be

问题 I have a custom imageView where i have a matrix and i can drag, zoom and now i can paint and delete points(coordinates)over it too. The problem is: how can i move that points after zoom or drag the matrix I have saved all the points in (Mark and Marking are custom clases with just 2 variables(x,y) float or int for save coordinates static ArrayList <Marking> listaPtos = new ArrayList<Marking>(); static ArrayList <Mark> listaMarcas = new ArrayList<Mark>(); how i save the coordinates? using

问题 For example, I have a latitude and longitude in decimal format (as opposed to Degrees-Hours-Minutes like lat=44.1° 9.5' 30''). To search for nearby objects, I must specify the search "radius" as a rectangle with four values: north = 44.1; south = -9.9; east = -22.4; west = 55.2; Is there a formula or rule of thumb how to convert decimal lat/long values into a rectangular bounding box, such that the given latitude/longitude is in the center of that box? Must I fiddle around myself with a WGS84

问题 I'm developing an application with Zoom and Pan Image..Now, i need to get Coordinates X,y Of Image Each when User Touch Image ( after Zoom and Pan ), Not coordinates of Screen such as method event.getX and event.getX..help me..Thank you very much 回答1: I know this question is a bit old, but i was facing the same problem, this actually did the trick. Android ImageView - Get coordinates of tap (click) regardless of scroll location or zoom scale 回答2: please use this formulla to convert actaull

问题 Hey, been trying to get the location of a users swipe so that I can have 3 swipe-able areas on screen and determine which section they react with based on the y coordinates of their swipe. This is the code CGPoint touchPoint = [recognizer locationOfTouch:0 inView:nil]; I have tried printing the touchPoint.y in a label and all i get is 0. How do I get the coordinates of the users swipe? Thanks. 回答1: Its strange but setting view as nil or self.view.window is returning 0. There is no mention of
