coordinates

I've read much about PDF extractions and libraries (as iText) but i just haven't found a solution to extract images and text (with coordinates) from a PDF. The task is to scan PDF with catalog of products and extract each image. There is an image code printed next to each image and also a list of product codes for products that are shown on the image. I know that there is no way to extract structured info from a PDF like this but with coordinates of all image and text objects I could write code to identify linked text by its distance from the image. Then I could split text using a RegExp and

Can I somehow get precise screen coordinates (relative to top left corner of the screen) of a DOM object. Through NPAPI\FireBreath or JavaScript. (Need this for plugin, that I'm writing with FireBreath) you move cursor to somewhere of the page ,and make a click event.(find the window,then GetWindowRect ,caculate a sutable position) then you can catch the event,record clientX and clientY. By this ,you build a bridge between two different coordinate system. Max Yari P.S.: I know I made this question long ago, but I want to summarize what I got at the end. element.offsetLeft\Top doesn't work

This type of question seems to have been asked numerous times but none of the solutions posted get me anywhere near the answer I need. I have this map of Northland, New Zealand and I'd like to map Lat/Long values to x/y (pixel) values on this image (http://i.stack.imgur.com/3ok4O.gif - which is 400px square) Right now I do not know the precise lat/long boundaries of this image, but I do have some example data which should be useful to someone who knows what they are doing. LAT LONG X Y -35.3989854471 173.504676819 192.92777494 196.760481649 -35.2647882735 174.121499062 271.426291418 176

I'm working on a project that uses the Kinect and OpenCV to export fintertip coordinates to Flash for use in games and other programs. Currently, our setup works based on color and exports fingertip points to Flash in (x, y, z) format where x and y are in Pixels and z is in Millimeters. But, we want map those (x, y) coordinates to "real world" values, like Millimeters, using that z depth value from within Flash. As I understand, the Kinect 3D depth is obtained via projecting the X-axis along the camera's horizontal, it's Y-axis along the camera's vertical, and it's Z-axis directly forward out

I have two 3D vectors called A and B that both only have a 3D position. I know how to find the angle along the unit circle ranging from 0-360 degrees with the atan2 function by doing: EDIT: (my atan2 function made no sense, now it should find the "y-angle" between 2 vectors): toDegrees(atan2(A.x-B.x,A.z-B.z))+180 But that gives me the Y angle between the 2 vectors. I need to find the X angle between them. It has to do with using the x, y and z position values. Not the x and z only, because that gives the Y angle between the two vectors. I need the X angle, I know it sounds vague but I don't

I am showing an image in an UIImageView and i'd like to convert coordinates to x/y values so i can show cities on this image. This is what i tried based on my research: CGFloat height = mapView.frame.size.height; CGFloat width = mapView.frame.size.width; int x = (int) ((width/360.0) * (180 + 8.242493)); // Mainz lon int y = (int) ((height/180.0) * (90 - 49.993615)); // Mainz lat NSLog(@"x: %i y: %i", x, y); PinView *pinView = [[PinView alloc]initPinViewWithPoint:x andY:y]; [self.view addSubview:pinView]; which gives me 167 as x and y=104 but this example should have the values x=73 and y=294.

I'm not looking for solution, I'm looking for a better solution or just a different way to do this by using some other kind of list comprehension or something else. I need to generate a list of tuples of 2 integers to get map coordinates like [(1, 1), (1, 2), ..., (x, y)] So I have the following: width, height = 10, 5 Solution 1 coordinates = [(x, y) for x in xrange(width) for y in xrange(height)] Solution 2 coordinates = [] for x in xrange(width): for y in xrange(height): coordinates.append((x, y)) Solution 3 coordinates = [] x, y = 0, 0 while x < width: while y < height: coordinates.append(

I'm saving 2-dimensional coordinates on an XML file with a structure similar to: <?xml version="1.0" encoding="utf-8" ?> <grid> <coordinate time="78"> <initial>540:672</initial> <final>540:672</final> </coordinate> </grid> I can open the XML file and read it via the XmlTextReader, but how do I loop through the coordinates specifically to retrieve both the time attribute and data between the initial and final nodes in some format similar to: string initial = "540:672"; string final = "540:672"; int time = 78; New Code: My New Code: //Read the XML file.
