Android: How to get the area size of a drawn path?

由 橙三吉。 提交于 2019-11-28 05:54:22
问题 My problem is to measure the surface area of a path. I generate a random Path and draw it on a canvas. After touching on this closen path, i want to get the area size of this drawn path. How can i get the real area size of this path? The pathes (shapes) looks like this here: link to the image 回答1: I found a solution. I generate a Region from the path and use a RegionIterator to get Rects inside the Region. With this Rects i can calculate the whole area of the path. private void calculateArea

Get the Surface Area of a Polyhedron (3D object)

问题 I have a 3D surface, (think about the xy plane). The plane can be slanted. (think about a slope road). Given a list of 3D coordinates that define the surface( Point3D1X , Point3D1Y , Point3D1Z , Point3D12X , Point3D2Y , Point3D2Z , Point3D3X , Point3D3Y , Point3D3Z , and so on), how to calculate the area of the surface? Note that my question here is analogous to finding area in 2D plane. In 2D plane we have a list of points that defines a polygon, and using this list of points we can find the

Using PathIterator to return all line segments that constrain an Area?

由 喜夏-厌秋 提交于 2019-11-28 02:03:51
问题 In Java, how would one employ PathIterator to iterate through the line segments that constrain an Area? The Area is bound only by lines (but curve support wouldn't hurt). The method should return a collection of all the line segments. 回答1: This works (in all situations, I believe), but it might require more thorough testing: Area area; // The value is set elsewhere in the code ArrayList<double[]> areaPoints = new ArrayList<double[]>(); ArrayList<Line2D.Double> areaSegments = new ArrayList

MATLAB fill area between lines

问题 I'm trying to do something similar to what's outlined in this post: MATLAB, Filling in the area between two sets of data, lines in one figure but running into a roadblock. I'm trying to shade the area of a graph that represents the mean +/- standard deviation. The variable definitions are a bit complicated but it boils down to this code, and when plotted without shading, I get the screenshot below: x = linspace(0, 100, 101)'; mean = torqueRnormMean(:,1); meanPlusSTD = torqueRnormMean(:,1) +

wpf Area Chart with Different Colors?

由 徘徊边缘 提交于 2019-11-28 01:40:48
问题 I a musing the MS toolkit charts and cannot figure out how to change the color of the areas. I need to populate the chart dynamically which means I do not know ahead of time how many sections the area chart will have. Here is the code I have. var a = new AreaSeries { Title = "a", IndependentValuePath = "Key", DependentValuePath = "Value", Background = Brushes.Plum }; I have tried to change both the Fore Ground and Background and no dice. mcChart.Series.Add(a); a = new AreaSeries { Title = "b"

Create clickable body diagram with Swift (iOS)

问题 I'm trying to recreate something for a iOS app (Swift) which I already made in HTML5 (using map area-coords ). I want to show a human body diagram that interacts with user clicks/touches. The body exists of let's say 20 different parts, and the user can select one or more body-parts. For every body-part there is a selected-state image that should appear when a part is selected. Clicking on a selected part will deselect it. After selecting one or more parts, the user can continue and will get

问题 I have this code, written using this: source1 and this: source 2 public static double CalculatePolygonArea(IList<GpsLocation> coordinates) { double area = 0; if (coordinates.Count > 2) { for (var i = 0; i < coordinates.Count-1; i++) { GpsLocation p1, p2; p1 = coordinates[i]; p2 = coordinates[i + 1]; area += ToRad(p2.Longitude - p1.Longitude) * (2 + Math.Sin(ToRad(p1.Latitude)) + Math.Sin(ToRad(p2.Latitude))); area = area * R * R / 2; } } return Math.Abs(area); } Here is my test code: [Fact]

can i have an onclick event on a imagemap area element

由 亡梦爱人 提交于 2019-11-27 22:45:24
I would like to put an onclick event on an area element. Here is my setup: <img id="image" src="wheel.png" width="2795" height="2795" usemap="#Map" > <map name="Map"> <area class="blue" onclick="myFunction()" shape="poly" coords="2318,480,1510,1284" href="#"> </map> I have tried 2 different ways to have an onclick event. Firstly i tried this: $(".blue").click( function(event){ alert('test'); }); I have also tried this: function myFunction() { alert('test'); } Neither of the above work. Do area elements support the above, or do they only support having a href? Thanks in advance! Pay attention:

find smallest area that contains all the rectangles

问题 This is an interview question. We are given dimensions of various rectangles, we have to find out the area(minimum) of rectangle that can enclose all of them? rectangles can be rotated also . test case:- input: 3 //number of rectangles 8 8 4 3 3 4 output: 88 11x8: + - - - - - - + + - + | | | | | | | | | | + - + | | + - + | | | | | | | | + - - - - - - + + - + i looked at a similar question asked before fitting rectangles in the smallest possible area the above approach looks at all
