Polling a web URL until event

- by Jaxo

I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

Retain numerical precision in an R data frame?

- by David

When I create a dataframe from numeric vectors, R seems to truncate the value below the precision that I require in my analysis: data.frame(x=0.99999996) returns 1 (see update 1) I am stuck when fitting spline(x,y) and two of the x values are set to 1 due to rounding while y changes. I could hack around this but I would prefer to use a standard solution if available. example Here is an example data set d <- data.frame(x = c(0.668732936336141, 0.95351462456867, 0.994620622127435, 0.999602102672081, 0.999987126195509, 0.999999955814133, 0.999999999999966), y = c(38.3026509783688, 11.5895099585560, 10.0443344234229, 9.86152339768516, 9.84461434575695, 9.81648333804257, 9.83306725758297)) The following solution works, but I would prefer something that is less subjective: plot(d$x, d$y, ylim=c(0,50)) lines(spline(d$x, d$y),col='grey') #bad fit lines(spline(d[-c(4:6),]$x, d[-c(4:6),]$y),col='red') #reasonable fit Update 1 Since posting this question, I realize that this will return 1 even though the data frame still contains the original value, e.g. > dput(data.frame(x=0.99999999996)) returns structure(list(x = 0.99999999996), .Names = "x", row.names = c(NA, -1L), class = "data.frame") Update 2 After using dput to post this example data set, and some pointers from Dirk, I can see that the problem is not in the truncation of the x values but the limits of the numerical errors in the model that I have used to calculate y. This justifies dropping a few of the equivalent data points (as in the example red line).

How do I select only the 4th and higher LIs in each UL?

- by KatieK

For this XHTML: <ul class="collapse"> <li>One</li> <li>Two</li> <li>Three</li> <li>Four</li> <li>Five</li> </ul> <ul class="collapse"> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> Using jQuery, how do I select only the 4th and higher LIs in each UL? I've tried: $("ul.collapse li:gt(2)").css("color", "red"); But it selects the 4th and higher LIs in the whole document. "Four", "Five", and "1", "2", "3", "4" are red.

Is there a free tool which can help visualize the logic of a stored procedure in SQL Server 2008 R2?

- by Hamish Grubijan

I would like to be able to plot a call graph of a stored procedure. I am not interested in every detail, and I am not concerned with dynamic SQL (although it would be cool to detect it and skip it maybe or mark it as such.) I would like the tool to generate a tree for me, given the server name, db name, stored proc name, a "call tree", which includes: Parent stored procedure. Every other stored procedure that is being called as a child of the caller. Every table that is being modified (updated or deleted from) as a child of the stored proc which does it. Hopefully it is clear what I am after; if not - please do ask. If there is not a tool that can do this, then I would like to try to write one myself. Python 2.6 is my language of choice, and I would like to use standard libraries as much as possible. Any suggestions? EDIT: For the purposes of bounty Warning: SQL syntax is COMPLEX. I need something that can parse all kinds of SQL 2008, even if it looks stupid. No corner cases barred :) EDIT2: I would be OK if all I am missing is graphics.

JavaScript: supposed to execute functions sequentially, not actually doing so?

- by AP257

I'm seeing a lot of answers on StackOverflow that say that JavaScript executes code sequentially, but I can actually see my own JavaScript not doing so. From the following code: function centre_map(lat, lng, zoom_level) { alert('centre_map'); map = new GMap2(document.getElementById('map_canvas')); var latlng = new GLatLng(lat, lng); map.setCenter(latlng, zoom_level); } function add_markers_within_bounds() { alert('add_markers_within_bounds'); // add numerous BLUE markers within map bounds using MarkerClusterer } function add_marker(lat, lng, place_name, grid, county) { alert('add_marker'); // add one ordinary RED Google Maps marker } centre_map('{{lat}}', '{{lng}}', 12); add_markers_within_bounds('{{grid}}', '{{place_name}}'); add_marker('{{lat}}', '{{lng}}', '{{place_name}}', '{{grid}}', '{{county}}'); I get the following sequence of events: 'centre_map' alert 'add_markers_within_bounds' alert 'add_marker' alert individual RED marker appears on map (i.e. add_marker renders) multiple BLUE markers appear on map (i.e. add_markers_within_bounds renders) Why doesn't add_markers_within_bounds complete before add_marker gets under way: and how can I make it do so? I know that one way might be to call add_marker from within add_markers_within_bounds, but for various reasons I'd rather keep it as a separate function.

How does git fetches commits associated to a file ?

- by liadan

I'm writing a simple parser of .git/* files. I covered almost everything, like objects, refs, pack files etc. But I have a problem. Let's say I have a big 300M repository (in a pack file) and I want to find out all the commits which changed /some/deep/inside/file file. What I'm doing now is: fetching last commit finding a file in it by: fetching parent tree finding out a tree inside recursively repeat until I get into the file additionally I'm checking hashes of each subfolders on my way to file. If one of them is the same as in commit before, I assume that file was not changed (because it's parent dir didn't change) then I store the hash of a file and fetch parent commit finding file again and check if hash change occurs if yes then original commit (i.e. one before parent) was changing a file And I repeat it over and over until I reach very first commit. This solution works, but it sucks. In worse case scenario, first search can take even 3 minutes (for 300M pack). Is there any way to speed it up ? I tried to avoid putting so large objects in memory, but right now I don't see any other way. And even that, initial memory load will take forever :( Greets and thanks for any help!

Where to start with the development of first database driven Web App (long question)?

- by Ryan

Hi all, I've decided to develop a database driven web app, but I'm not sure where to start. The end goal of the project is three-fold: 1) to learn new technologies and practices, 2) deliver an unsolicited demo to management that would show how information that the company stores as office documents spread across a cumbersome network folder structure can be consolidated and made easier to access and maintain and 3) show my co-workers how Test Drive Development and prototyping via class diagrams can be very useful and reduces future maintenance headaches. I think this ends up being a basic CMS to which I have generated a set of features, see below. 1) Create a database to store the site structure (organized as a tree with a 'project group'-project structure). 2) Pull the site structure from the database and display as a tree using basic front end technologies. 3) Add administrator privileges/tools for modifying the site structure. 4) Auto create required sub pages* when an admin adds a new project. 4.1) There will be several sub pages under each project and the content for each sub page is different. 5) add user privileges for assigning read and write privileges to sub pages. What I would like to do is use Test Driven Development and class diagramming as part of my process for developing this project. My problem; I'm not sure where to start. I have read on Unit Testing and UML, but never used them in practice. Also, having never worked with databases before, how to I incorporate these items into the models and test units? Thank you all in advance for your expertise.

How can I programmatically get the connection status of OSX network services?

- by BigBrainz

In the OS X System Preferences, when I click on 'Network' I see a green dot by 'Ethernet', and red dots by 'AirPort' and 'FireWire'. This is because I turned off AirPort and FireWire, as I access networks and the Internet via Ethernet. I need to programmatically determine which of these network services displayed in System Preferences have green dots and which have red dots. For Ethernet and FireWire the displayed status is 'Connected' or 'Not Connected', and for AirPort the displayed status is 'On' or 'Off'. Perhaps other network services have other status labels. I have picked through all the plist files in '/Library/Preferences/SystemConfiguration', particularly 'preferences.plist' and 'NetworkInterfaces.plist'. I can get all sorts of information there, such as the Location set, network service order, proxy information (which is also important to my task), but I cannot find how to determine whether a given network service is on or off--the equivalent of having the green dot displayed. I have also tried using System Configuration framework, specifically the SCNetworkConnectionGetStatus function, but all I get are invalid connection statuses. Does anyone know how to actually retrieve this connection status information? Thanks.

SVG 100% document height don't work

- by whizzo

I'm trying to fill a document with a SVG image using the width="100%" and height="100%" properties, I have height="100%" in html and body tags too, and different colours for body(red) and svg(blue). Result is a full height svg but with a scrollbar in the right, and a thin line of red(body) at the bottom. ¿How can I fill the document with the svg without the scrollbar? Thanks. The code: <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>SVG full page</title> <style> html, body { margin: 0; padding: 0; height: 100%; background-color: #ff0000; } </style> </head> <body> <svg width="100%" height="100%"> <rect x="0" y="0" width="100%" height="100%" fill="#0000ff"></rect> </svg> </body> </html>

Do running times match with O(nlogn)?

- by user472221

Hi I have written a class(greedy strategy) that at first i used sort method which has O(nlogn) Collections.sort(array, new SortingObjectsWithProbabilityField()); and then i used the insert method of binary search tree which takes O(h) and h here is the tree height. for different n ,the running time will be : n,running time 17,515428 33,783340 65,540572 129,1285080 257,2052216 513,4299709 which I think is not correct because for increasing n , the running time should almost increase. This method will take the running time: Exponent = -1; for(int n = 2;n<1000;n+=Math.pow(2,exponent){ for (int j = 1; j <= 3; j++) { Random rand = new Random(); for (int i = 0; i < n; i++) { Element e = new Element(rand.nextInt(100) + 1, rand.nextInt(100) + 1, 0); for (int k = 0; k < i; k++) { if (e.getDigit() == randList.get(k).getDigit()) { e.setDigit(e.getDigit() + 1); } } randList.add(e); } double sum = 0.0; for (int i = 0; i < randList.size(); i++) { sum += randList.get(i).getProbability(); } for (Element i : randList) { i.setProbability(i.getProbability() / sum); } //Get time. long t2 = System.nanoTime(); GreedyVersion greedy = new GreedyVersion((ArrayList<Element>) randList); long t3 = System.nanoTime(); timeForGreedy = timeForGreedy + t3 - t2; } System.out.println(n + "," + "," + timeForGreedy/3 ); exponent++; } thanks

Simple Oracle File repository with folder hierarchy

- by Ope

I have an application that stores large amount of files (XML and binary) in folder hierarchies. Currently the main method is storing them in file system or using a legacy CMS, which we want to get rid of. The CMS supports Oracle and a customer wants to keep the files in Oracle because of enterprise policies (backup etc.) The question is: Is there a simple implementation of file repository with folder hierarchy for Oracle? What I am looking for is a small .Net component or example code (PL/SQL and/or .Net) that would have the following methods: Create, Delete, Exists Folder CRUD file Move and potentially Copy file or directory Access to files and folders with paths like "/root/folder1/folder2/file.xml" Ability to get all the files and folders in a folder and potentially also the entire directory tree Tree traversal, getting the parent, all children etc. needs to be fast. I need the implementation in .Net, but if it was just the stored procedures, I could create the .Net calling code. I have pointers to generic articles for creating hierarchies in DB, so if I need to do it from scratch, I know where to start. What I am asking here, is there already an implementation that I could take without doing this from scratch? It seems like such a generic requirement... If the answer is a CMS, Document management system or such it should be Open Source or at least quite cheap (some hundreds / server) and it should be possible to deploy it XCopy - hopefully only couple of DLL:s. I do not need - or want - a full featured big CMS with dozens of dlls and especially not an msi-installation. I have tried to google this, but the words "repository", "CMS", "file hierarchy" etc. give so many answers, the searches are pretty much useless. Thanks, OPe

Vacancy Tracking Algorithm implementation in C++

- by Dave

I'm trying to use the vacancy tracking algorithm to perform transposition of multidimensional arrays in C++. The arrays come as void pointers so I'm using address manipulation to perform the copies. Basically, there is an algorithm that starts with an offset and works its way through the whole 1-d representation of the array like swiss cheese, knocking out other offsets until it gets back to the original one. Then, you have to start at the next, untouched offset and do it again. You repeat until all offsets have been touched. Right now, I'm using a std::set to just fill up all possible offsets (0 up to the multiplicative fold of the dimensions of the array). Then, as I go through the algorithm, I erase from the set. I figure this would be fastest because I need to randomly access offsets in the tree/set and delete them. Then I need to quickly find the next untouched/undeleted offset. First of all, filling up the set is very slow and it seems like there must be a better way. It's individually calling new[] for every insert. So if I have 5 million offsets, there's 5 million news, plus re-balancing the tree constantly which as you know is not fast for a pre-sorted list. Second, deleting is slow as well. Third, assuming 4-byte data types like int and float, I'm using up actually the same amount of memory as the array itself to store this list of untouched offsets. Fourth, determining if there are any untouched offsets and getting one of them is fast -- a good thing. Does anyone have suggestions for any of these issues?

Array of Sentences?

- by user1869915

Javascript noob here.... I am trying to build a site that will help my kids read predefined sentences from a select group, then when a button is clicked it will display one of the sentences. Is an array the best option for this? For example, I have this array (below) and on the click of a button I would like one of these sentences to appear on the page. <script type="text/javascript"> Sentence = new Array() Sentence[0]='Can we go to the park.'; Sentence[1]='Where is the orange cat? Said the big black dog.'; Sentence[2]='We can make the bird fly away if we jump on something.' Sentence[3]='We can go down to the store with the dog. It is not too far away.' Sentence[4]='My big yellow cat ate the little black bird.' Sentence[5]='I like to read my book at school.' Sentence[6]='We are going to swim at the park.' </script> Again, is an array the best for this and how could I get the sentence to display? Ideally I would want the button to randomly select one of these sentences but just displaying one of them for now would help. Thanks

Why doesn't my <div> float around another floated <div> while other elements do?

- by user1848605

I have a container with background color green. Inside that green <div>, I have a <div> which is black and styled as a box (50px x 50px) - this <div> is floated to the left. Now if I add a <p> to my markup after the grey <div>, I'd expect it to float around the grey <div>. And it does. However, when I substitue with another <div> which is styled as box (set height and width), it doesn't float around anymore, but disappears behind the floating div. Even if I have first paragraphs which are floating around correctly and THEN I add the div (box), the paragraphs stop floating around and appear on another line. HTML: <div id="greencontainer"> <div id="blackbox"></div>  <p>A paragraph that floats around the previous div</p> <div id="anotherbox"></div>  </div> CSS: #blackbox { width:50px; height:50px; background-color:black; float:left; } #p { margin:0px; padding:0px; } #anotherbox { width:50px; height:50px; background-color:grey; }

UIWebView loading/randering error after resize

- by user1343869

I have a screen with 2 UIWebView. The user can drag the views left and right to make the right and left view bigger (respectively) and the other one smaller (like UISplitView but customized and self made). I'm loading .html pages from strings and local .css files. After resizing the UIWebView If I load a new page there will be a black or white stripe on the right side of the UIWebView. This stripe is part of the web view (not a space between the views), and if I scroll the webView up and then down, the stripe will vanish and the page will be presented correctly. This issue occurs only in iOS 6 and only on the device (on the simulator it doesn't occur). Some notes: - The .css file contains elements with fixed position. Changing to absolute position didn't solve the problem but changed it: the black stripre occured during the drag. - As slower the drag is, the stripe will be bigger. - After resize the page is presented correctly, only when I load a new page the stripe is shown. - The time between resizing the web view and loading a page doesn't matter, it can be straight away or after couple of minutes. Now, as a workaround I create a new UIWebView and copy the old properties to the new. But than I need to reload the presented page which make a white blink... Any idea why does it happens, and how to fix it?

php png image transparency

I have been working with some code to draw a circle but I am having problems with removing the black background from the shape. I am using imagecopyresampled for its AA features in order to draw a smooth circle, so I can't use a different drawing function. Thanks. <?php $img_2 = imagecreatetruecolor(200, 200); $red = imagecolorallocate($img_2, 255, 0, 0); imagefill($img_2, 0, 0, $red); //set circle values $xPos = 50; $yPos = 80; $diameter = 40; $img_1 = imagecreatetruecolor(($diameter + 2) * 2, ($diameter + 2) * 2); $green = imagecolorallocate($img_1, 0, 255, 0); //draw the circle imagefilledarc($img_1, $diameter+1, $diameter+1, ($diameter + 2) * 2, ($diameter + 2) * 2, 0, 360, $green, IMG_ARC_PIE); imagecopyresampled($img_2, $img_1, $xPos, $yPos, 0, 0, $diameter+2, $diameter+2, ($diameter + 2) * 2, ($diameter + 2) * 2); header("Content-type: image/png"); imagepng($img_2); imagedestroy($img_1); imagedestroy($img_2); ?>

Color difference between vista and Win7

- by MSGrimpeur

Have an indicator in the form of an image which is displayed in a graphics viewport. The indicator can be any colour the user selects so we created a single image with a pallette and change a specific color in the pallette to the one the user picks using the following code. /// <summary> /// Copies the image and sets transparency and fill colour of the copy. The image is intended to be a simple filled shape such as a square /// with the inside all in one colour. /// </summary> /// <remarks>Assumes the fill colour to be changed is Red, /// black is the boundary colour and off white (RGB 233,233,233) is the colour to be made transparent</remarks> /// <param name="image"></param> /// <param name="fillColour"></param> /// <returns></returns> protected Bitmap CopyWithStyle(Bitmap image, Color fillColour) { ColorPalette selectionIndicatorPalette = image.Palette; int fillColourIndex = selectionIndicatorPalette.IndexOf(Color.Red); selectionIndicatorPalette.Entries[fillColourIndex] = fillColour; image.Palette = selectionIndicatorPalette; Bitmap tempImage = image; tempImage.MakeTransparent(transparentColour); return tempImage; } To be honest I'm not sure if this is a bit cludgy and there is some smarter approach or not, so any thoughts there would help. However the main issue is that this appears to work fine on Win7 but in vista and XP the color does not change. Has any one seen this before. I've found one or two articles that suggest there are some differences in ARGB between them but nothing particularly concrete. Any help greatfully accepted.

Unordered list appears higher than div

- by LordArmadillo

I am trying to create a simple page, which I normally can without any trouble. However, the unordered list appears higher up the page than the div. I do know a solution for this, however I cannot remember it. The page goes like this: <style> ul.menu { list-style-type: none; margin:150; margin-bottom:30px; padding:0; display: block; width: 708px; margin-left: auto; margin-right: auto; } li.menu { float:left; display: block; width: 118px; } a.menu:link,a.menu:visited { color:black; display:block; border:1px solid black; background-color:#FFFF00; width:118px; text-align:center; text-decoration:none; font-family:"Courier New", Courier, monospace } a.menu:hover { background-color:#FFBB11; } </style> <div id="head"> My images here & such</div> <ul class="menu"> <li class="menu"> <a class="menu">Main</a> </li> </ul> Normally I welcome suggestions to change my code, but I have a deadline today! So, quick & simple help would be appreciated! Thanks! LordArmadillo

How do I make a shrinkable scrollbar?

- by diadem

What I want: <div style="overflow:scroll;width:100%;height:50%;">   <div style="height:500px;width:400px;border:solid 3px red;"> </div> </div> <div style="overflow:scroll;width:100%;HEIGHT:50%;">   <div style="height:500px;width:400px;border:solid 3px red;"> </div> </div> Notice how if I shrink the height of the window the scrollbars shrink. This is the functionality I want. The issue: I want to make something similar to the above, only with a fixed height of 100 pixels for the top div. If I do this in practice the bottom scrollbar no longer shrinks as I shrink the page - the system adds an outer scrollbar to manage both sections. I don't want this, I want to retain the behavior seen above. How do I do this?

Position a div relative to a top-level container?

- by Seifeddine Dridi

I'm trying to model an HTML document which only contains div elements positioned in absolute. For each div, properties left and top are precalculated wrt. the top-level div, but a problem occurs with nested divs since according to the CSS standard an element is positioned relative to its first ancestral element whose positioning is either relative or absolute. Does anyone know any workaround? EDIT: small code snippet that demonstrates the problem <html> <body style="background-color: #444444"> <div style="position: relative; background-color: white;"> <div style="position: absolute; background-color: red; width: 4cm; height: 3cm; top: 1cm">div 1 <div style="position: absolute; background-color: green; top: 4cm"> div 1.1</div> </div> </div> </body> </html> The green div is expected to be positioned right after the red div, instead there is a gap of 1cm in between.

Voice Recognition Google API

- by user2966744

thanks for reading. I'm creating a simple web based drawing app that uses speech recognition. I have created a simple page, the project is on github here: https://github.com/a5hton/speechdraw It has a 16x16 pixel grid. I would like to be able to draw on this grid by using simple words. For example if you say "right", the pixel to the right will be colored black. If you say "down" the pixel below the last one will be colored black. You can say up, down, left or right and the corresponding pixels will be colored. Saying "erase" will switch to erase mode, colouring the pixels back to their original color. Saying "lift" will lift the pen off the page. Saying "draw" will enable the draw mode. Could you please help me work out how to make this happen. Please see the simple page at to get an understanding. Thank you! Cheers, Michael

Just a small help about switch's use

- by Laurent Fournier

If an answer on this already exist, my apologies i've not found on this question... is this statement correct if i want presice actions on integers from -2 to 0, and for those between 1 and 6 apply the same methods with only my integer who'll change ? Like this: public void setCaseGUI(Point pt, int i, boolean b){ plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setSelected(b); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setIcon(null); switch(i) { case -2: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText("F"); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(Color.red); break; case -1: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText("B"); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(Color.red); break; case 0: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText(""); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(null); break; case 1: case 2: case 3: case 4: case 5: case 6: case 7: case 8: plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setText(String.valueOf(i)); plateau.cellule[(int)pt.getAbs()][(int)pt.getOrd()].setForeground(null); break; default: System.out.println("Erreur de changement d'état/case !"); } } Please don't be too harsh on me i've started to learn dev only a few month ago

Is it wrong for a context (right click) menu be the only way a user can perform a certain task?

- by Eric

I'd like to know if it ever makes sense to provide some functionality in a piece of software that is only available to the user through a context (right click) menu. It seems that in most software I've worked with the right click menu is always used as a quick way to get to features that are otherwise available from other buttons or menus. Below is a screen shot of the UI I'm developing. The tree view on the right shows the user's library of catalogs. Users can create new catalogs, or add and remove existing catalogs to and from their library. Catalogs in their library can then be opened or closed, or set to read-only. The screen shot shows the context menu I've created for the browser. Some commands can be executed independently from any specific catalog (New, Add). Yet the other commands must be applied to a specifically selected catalog (Close, Open, Remove, ReadOnly, Refresh, Clean UP, Rename). Currently the "Catalog" menu at the top of the window looks identical to this context menu. Yet I think this may be confusing to the users as the tree view which shows the currently selected catalog may not always be visible. The user may have switched to the Search or Filters tab, or the left pane may be hidden entirely. However, I'm hesitant to change the UI so that the commands that depends on a specifically selected catalog are only available through the context menu.

Load image blurred Android

- by Mira

I'm trying to create a map for a game through an image, where each black pixel is equivalent to a wall, and yellow to flowers(1) and green grass(0) so far i had this image (50x50): http://i.imgur.com/Ydj9Cp2.png the problem here seems to be that, when i read the image on my code, it get's scaled up to 100x100, even tough i have it on the raw folder. I can't let it scale up or down because that will put noise and blur on the image and then the map won't be readable. here i have my code: (...) Bitmap tab=BitmapFactory.decodeResource(resources, com.example.lolitos2.R.raw.mappixel); //tab=Bitmap.createScaledBitmap(tab, 50, 50, false); Log.e("w", tab.getWidth()+"."+tab.getHeight()); for (int i = 0; i < tab.getWidth(); i++) { for (int j = 0; j < tab.getHeight(); j++) { int x = j; int y = i; switch (tab.getPixel(x, y)) { // se o é uma parede case Color.BLACK: getParedes()[x][y] = new Parede(x, y); break; case Color.GREEN: fundo.add(new Passivo(x,y,0)); break; default: fundo.add(new Passivo(x,y,1)); } } } How can i read my image Map without rescaling it?
