coordinate-systems

Is there any tool in some PDF Viewer/Editor like Acrobat, Evince, etc. where I can navigate and watch coordinates(i.e. (x,y)) of any selected point in PDF-document? I've found that Gimp is perfect for this! It even has different units of measure, so this is my choice To explain @michael Z's answer, I found the following works: These steps are for paint.net, but most image manipulation programs like The Gimp should be similar: open the pdf up in reader. screenshot it. paste into paint.net choose image > flip vertical. choose view >show rulers. Also tick pixels. Resize image to use inches and be

For my game I need functions to translate between two coordinate systems. Well it's mainly math question but what I need is the C++ code to do it and a bit of explanation how to solve my issue. Screen coordiantes: a) top left corner is 0,0 b) no minus values c) right += x (the more is x value, the more on the right is point) d) bottom +=y Cartesian 2D coordinates: a) middle point is (0, 0) b) minus values do exist c) right += x d) bottom -= y (the less is y, the more at the bottom is point) I need an easy way to translate from one system to another and vice versa. To do that, (I think) I need

I was wondering if there is a package to plot a 2D representation of the outline of a human body? Being in 2D, plotting either the front/back/side at any one time would presumably be the easiest way to accomplish this. The output would be something similar to this (though this is not the best use of such a diagram): Source: http://emj.bmj.com/content/20/5/434.full Ideally, plotting a subset of data as is done for the world with map(regions="Australia") would be possible in the form body.map(regions="left.hand") . In that respect, would it be appropriate to base such a model on the maps package

I am trying to convert geographic coordinates (degrees) into UTM coordinates (meters) and keep getting an error message that a "Non finite transformation detected." Do you know how I can fix this? Here is the code I used: > GPS.Points <- Gomer.Data[, c('Longitude', 'Latitude')] > head(GPS.Points) Longitude Latitude 1 23.85474 -19.52211 2 23.85531 -19.52243 3 23.85534 -19.52257 4 23.85580 -19.52346 5 23.85551 -19.52380 6 23.85513 -19.52360 > GPS.Points.Spatial.Data <- SpatialPoints(GPS.Points, proj4string=CRS("+proj=longlat +ellps=WGS84")) > GPS.Points.Spatial.Data[1] SpatialPoints: Longitude

I know there are many many questions about sorting javascript arrays by multiple values, but none of the answers solved my problem. I have an array of coordinates like: x | y -------- 10 20 12 18 20 30 5 40 100 2 How can I get the coordinate that is closest to the point of origin? Calculate the distance of each point using Math.sqrt( Math.pow(x, 2) + Math.pow(y, 2) ); Take the result that's the lowest var points = [ {x: 10, y: 20}, {x: 12, y: 18}, {x: 20, y: 30}, {x: 5, y: 40}, {x: 100, y: 2} ]; function d(point) { return Math.pow(point.x, 2) + Math.pow(point.y, 2); } var closest = points

I want to get the origin of scrollView in the window coordinate system. For Example, presently, scollView origin is (0,51). But in window coordinate system it should be 51 + 44(navigation bar height)+20(status bar height) = 115. Means in window coordinate system the scrollView.frame.origin should be (0,115). I tried with convertPoint: methods but getting (0,51) or (0,0) sometimes. Please provide a solution to this. Thanks TechZen It sounds like your not converting between the proper views. A view's frame is set to the coordinates of it's superview, not its own internal coordinates, so if you
