coordinates

I have a multi-line TextView . Is there a way to get the x coordinate of the pixel to the left of a character e.g. the 3rd character? In my case it will always be the 3rd character, but a general solution would be nicer. I have the y coordinate of the pixel just above the character using: Layout textViewLay = mTextView.getLayout(); int posY = textViewLay.getLineTop(0); but the x coordinate has me stumped. Any ideas? I'm probably missing something really simple. Try to use this code: Rect bounds = new Rect(); Paint tpaint = textView.getPaint(); tpaint.getTextBounds(text,0,2,bounds); int height

I am having some troubles trying to connect separate points in my picture (see below). Right now, the code I have is as follows: first_time = resulting_coords[0:40] for i in range(len(first_time)): if(i < (len(first_time))-1): cv2.line(copy_test_image[0], (resulting_coords[i,0],resulting_coords[i,1]), (resulting_coords[i+1,0],resulting_coords[i+1,1]), (0,0,225), 2) elif(i>=(len(first_time))-1): # print(i) cv2.line(copy_test_image[0], (resulting_coords[i,0],resulting_coords[i,1]), (resulting_coords[0,0],resulting_coords[0,1]), (0,0,225), 2) Which actually gives the result I want: Results in But

I have 2 coordinates and would like to do something seemingly straightforward. I want to figure out, given: 1) Coordinate A 2) Course provided by Core Location 3) Coordinate B the following: 1) Distance between A and B (can currently be done using distanceFromLocation) so ok on that one. 2) The course that should be taken to get from A to B (different from course currently traveling) Is there a simple way to accomplish this, any third party or built in API? Apple doesn't seem to provide this but I could be wrong. Thanks, ~Arash EDIT: Thanks for the fast responses, I believe there may have been

The thing is I have some graphics shown in a form, rectangle for example, and I want to capture when the point gets over thees fields. So I Thoght I try to find the corrrdinates for thees rectangles, but as thay are the coords in the form it dose not match the ones with the mouse location. So I wonder is there a way to find what coord on the screen a Point has on the screen and not in the form or controller? Each control hs PointToFoo methods for conversion. Note that you should call this from the parent of the object who's location you want: Point scrPos = this.PointToScreen(panel1.Location);

I have millions of GPS coordinates and want to quickly add a column of the country of the coordinates. My current method works but is extremely slow: library(data.table) #REPRODUCE DATA data <- data.table(latitude=sample(seq(47,52,by=0.001), 1000000, replace = TRUE), longitude=sample(seq(8,23,by=0.001), 1000000, replace = TRUE)) #REQUIRED PACKAGES if (!require("sp")) install.packages("sp") if (!require("rworldmap")) install.packages("rworldmap") if (!require("sf")) install.packages("sf") library(sp) library(rworldmap) library(sf) #CURRENT SLOW FUNCTION coords2country = function(points,latcol

I am having the following function to get the mouse click positions(coordinates). $('#myCanvas').on('click', function(e) { event = e; event = event || window.event; var canvas = document.getElementById('myCanvas'), x = event.pageX - canvas.offsetLeft, y = event.pageY - canvas.offsetTop; alert(x + ' ' + y); }); I need to get the mouse point on clicking a position and also secound mouse point position after draging the same. ie., mousedown point and mouseup points. Try a little different setup: var canvas = myCanvas; //store canvas outside event loop var isDown = false; //flag we use to keep
