coordinates

I have an array that looks like this: 1. coordinates = [ [16.343345, 35.123523], 2. [14.325423, 34.632723], 3. [15.231512, 35.426914], 4. [16.343345, 35.123523], 5. [15.231512, 32.426914] ] The latitude on line 5 is the same as on line 3, but they have different longitudes and are therefore not duplicates. Both the latitude and longitude are the same on line 3 and 6, and are therefore duplicates and one should be removed. The difficulty in this question that different arrays never compare equal even if they contain same values. Therefore direct comparison methods, like indexOf won't work. The

Note: This is question to which I have already found an answer. It seems that posting a question after finding an interesting answer is encouraged , so I am posting this. Someone else is likely to have the same problem and find this useful. I have an iOS app that produces charts. Shortly after publishing an update, a user sent me this panicky email: "the latest update has modified the curves ... not seen more growth curves and inserted data are represented as a line descending ... before you could see perfectly well Help me" I get him to send a screenshot and give more detail. He has an iPhone

I have a problem with placing my views (my class extends View ) in a specific location. I have designed a game that treats the screen as a net of grids. I get from the user x and y coordinates of a specific view (I have different types of views). My first mission is to set the correct view in its place. How can I do it? I am using RelativeLayout for the screen. P.S. I don't want to use AbsoluteLayout params because it was truncated. wsgfz This is not the best way to achieve it, but it's a solution... Create a class that extends your parent ViewGroup , say RelativeLayout or some other ViewGroup

Basically I want to move an object from point A ( 10x,10y ) to a position on the canvas where the mouse has been clicked ( 255x,34y ). I'm currently using a method, but it goes from ++X then ++Y to coordinates; up then right. I want it to go straight to position, likes an animation on a path. Slowing going from point A to Point B. When you “move” an object, what you really need to do is erase the object and redraw it First code a function that will redraw the rect at a specified x,y function draw(x,y){ ctx.clearRect(0,0,canvas.width,canvas.height); ctx.beginPath(); ctx.fillStyle="skyblue"; ctx

I have a UILabel with some text, say "Hello World abcdefg" The label can have multiple lines, different font sizes etc. Question : How do I find the coordinates of all letters "d" in this UILabel. Logical first step is find the position of those characters in the string (UILabel.text), but then how do I translate that into coordinates when it's actually drawn on screen The idea is to find those coordinates and draw something custom on top of that character (basically to cover it with a custom image) The basic tools for measuring text on iPhone are in UIStringDrawing.h but none of them do what

I am trying to use a Canvas to display objects that have "world" location (rather than "screen" location). The canvas is defined like this: <Canvas Background="AliceBlue"> <ItemsControl Name="myItemsControl" ItemsSource="{Binding MyItems}"> <Image x:Name="myMapImage" Panel.ZIndex="-1" /> <ItemsControl.ItemTemplate> <DataTemplate> <Canvas> <TextBlock Canvas.Left="{Binding WorldX}" Canvas.Top="{Binding WorldY}" Text="{Binding Text}" Width="Auto" Height="Auto" Foreground="Red" /> </Canvas> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Canvas> MyItem is defined like this: public

Im developing an app that brings the user a quick list of "info" items but i want to set an options so that he receives this items as notifications when he is leaving home or work. I noticed (using google now on my device) that they can tell where the user lives and works so that they can push you notifications whenever you leave or arrive at one of this places (a sort of if this then that). Is there any way yo obtain the coordinates (lat and long) that Google Now (they come from google maps) uses for this?. I mean something like (GoogleMapsApi > GetFavorite Locations > Get Home Location > Get
