  • What is the correct date format for a Date column in YUI DataTable ?

    - by giulio
    I have produced a data table. All the columns are sortable. It has a date in one column which I formatted dd/mm/yyyy hh:mm:ss . This is different from the default format as defined in the doco, but I should be able to define my own format for non-american formats. (See below) The DataTable class provides a set of built-in static functions to format certain well-known types of data. In your Column definition, if you set a Column's formatter to YAHOO.widget.DataTable.formatDate, that function will render data of type Date with the default syntax of "MM/DD/YYYY". If you would like to bypass a built-in formatter in favor of your own, you can point a Column's formatter to a custom function that you define. The table is generated from HTML Markup, so the data is held within "" tags. This gives me some more clues about compatible string dates for javascript: In general, the RecordSet expects to hold data in native JavaScript types. For instance, a date is expected to be a JavaScript Date instance, not a string like "4/26/2005" in order to sort properly. Converting data types as data comes into your RecordSet is enabled through the parser property in the fields array of your DataSource's responseSchema I suspect that the I'm missing something in the date format. So what is an acceptable string date for javascript, that Yui dataTable will recognise, given that I want format it as "dd/mm/yyyy hh:mm:ss" ?

  • open source business intelligence solutions

    - by opensas
    which open source business intelligence solution would you recommend? All I need is to build some cubes and let the end user play with dimensions, filter data, sort, etc, and once it's done being able to export it to excel... I'd like the solution to be as simple and easy on resources as possible, and also I'd like it to be as much open source as possible, by the way. I've heard that many solutions available do have many restrictions when it comes to there community version. I'd like to ear your advices and the pros/cons of each alternative, to help me choose the right tool, and if you could point me to some basic demo and tutorial to get started. thanks a lot ps: I'm using sql server databases, they aren't huge databases (in general less than a million records) and I doesn't necessarily have to work on "live" data... ps: some useful links: http://en.wikipedia.org/wiki/Business_intelligence_tools#Open_source_free_products http://www.manageability.org/blog/stuff/open-source-java-business-intelligence http://www.jaspersoft.com/jasperanalysis http://community.pentaho.com/projects/bi_platform/ http://community.pentaho.com/faq/platform_licensing.php http://www.eclipse.org/birt/phoenix/ http://www.spagoworld.org/xwiki/bin/view/SpagoWorld/ http://docs.google.com/viewer?a=v&q=cache:vhsqMQXwCUkJ:www.ow2.org/xwiki/bin/download/Activities/EuropeLocalChapterWebinars/ELCWebinarOSBI.pdf+open+source+business+intelligence&hl=en&pid=bl&srcid=ADGEESgpJJ2MqaKprJQOF2jX2UXCZQjg_asv8d7EVYtq0Vma-e-tR1tFxS-I0SOW0IhJC5acYc94rkDOrgP1WckCp_vk4qhKqR9y2Klp_u9cL8hlXoKoUpMkpAd5wabu61A4W0y15E5P&sig=AHIEtbRJ5FAI-3YK-qtayPjKkF_CwOgZag

  • Sorting, Filtering and Paging in ASP.NET MVC

    - by ali62b
    What is the best approach to implement these features and which part of project would involved? I see some example of JavaScript grids, but I'm talking about a general approach which best fits the MVC architecture. I've considered configuring routes and models to implement these features but I don't have a clear idea that if this is the right approach to implementing such features. On the one hand, I think if we put logic in routes (item/page/sort/), we would have benefits like bookmarking and avoiding JavaScript. On the other hand if we use JavaScript grids, we can have behavior like the old school grid views in ASP.NET web forms. I find that using HTML helpers may be useful for paging, but have no idea if they are good for sorting or not. I've looked at jQuery, tableSorter and quick search plug-ins, but they work just on the currently-fetched data and won't help in real sorting and filtering that may need to touch the database. I have some thoughts on using these tools side by side with AJAX to get something which works, but I have no idea if there are similar efforts done yet anywhere. Another approach I looked at was using Dynamic Data on web forms, but I didn't find any suggestions out there as to whether or not it is a good idea to integrate MVC and DD. I know implementing filtering and sorting for an individual case is simple (although it has some issues like using Dynamic LINQ, which is not yet a standard approach), but creating a sorting or filtering tool which works in all cases is the idea I'm looking for. (Maybe this is because I want have something in hand when web form developers are wondering why I'm writing same code each time I want to implement a sort scenario for different Entities).

  • Why does Clojure hang after hacing performed my calculations?

    - by Thomas
    Hi all, I'm experimenting with filtering through elements in parallel. For each element, I need to perform a distance calculation to see if it is close enough to a target point. Never mind that data structures already exist for doing this, I'm just doing initial experiments for now. Anyway, I wanted to run some very basic experiments where I generate random vectors and filter them. Here's my implementation that does all of this (defn pfilter [pred coll] (map second (filter first (pmap (fn [item] [(pred item) item]) coll)))) (defn random-n-vector [n] (take n (repeatedly rand))) (defn distance [u v] (Math/sqrt (reduce + (map #(Math/pow (- %1 %2) 2) u v)))) (defn -main [& args] (let [[n-str vectors-str threshold-str] args n (Integer/parseInt n-str) vectors (Integer/parseInt vectors-str) threshold (Double/parseDouble threshold-str) random-vector (partial random-n-vector n) u (random-vector)] (time (println n vectors (count (pfilter (fn [v] (< (distance u v) threshold)) (take vectors (repeatedly random-vector)))))))) The code executes and returns what I expect, that is the parameter n (length of vectors), vectors (the number of vectors) and the number of vectors that are closer than a threshold to the target vector. What I don't understand is why the programs hangs for an additional minute before terminating. Here is the output of a run which demonstrates the error $ time lein run 10 100000 1.0 [null] 10 100000 12283 [null] "Elapsed time: 3300.856 msecs" real 1m6.336s user 0m7.204s sys 0m1.495s Any comments on how to filter in parallel in general are also more than welcome, as I haven't yet confirmed that pfilter actually works.

  • Bundle a Python app as a single file to support add-ons or extensions?

    - by Brandon Craig Rhodes
    There are several utilities — all with different procedures, limitations, and target operating systems — for getting a Python package and all of its dependencies and turning them into a single binary program that is easy to ship to customers: http://wiki.python.org/moin/Freeze http://www.pyinstaller.org/ http://www.py2exe.org/ http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html My situation goes one step further: third-party developers will be wanting to write plug-ins, extensions, or add-ons for my application. It is, of course, a daunting question how users on platforms like Windows would most easily install plugins or addons in such a way that my app can easily discover that they have been installed. But beyond that basic question is another: how can a third-party developer bundle their extension with whatever libraries the extension itself needs (which might be binary modules, like lxml) in such a way that the plugin's dependencies become available for import at the same time that the plugin becomes available. How can this be approached? Will my application need its own plug-in area on disk and its own plug-in registry to make this tractable? Or are there general mechanisms, that I could avoid writing myself, that would allow an app that is distributed as a single executable to look around and find plugins that are also installed as single files?

  • If I wanted to make a Pac-Man Game?

    - by SoulBeaver
    I am immediately placing this as a community wiki thing. I don't want to ask for help in programming yet or have even a specific question about programming, but rather the process and the resources needed to make such a game. To put it simply: My college friend and I decided to give ourselves a really big challenge to further our skills in programming. In six months time we want to show ourselves a Pac-Man game. Pac-Man will be AI-controlled like the Ghosts and whichever Pac-Man lives the longest after a set of tries wins. This isn't like anything we've done so far. The goal here, for me, isn't to create a perfect game, but to try and complete it, learn a whole bunch in the process. Even if I don't finish in the time, which is a good possibility, I would want to have at least tried this. So my question is this: How should I start preparing myself? I already have started vector math, matrices, all that fun stuff. My desired platform would be DirectX 9.0c; is that advisable? Keep in mind that this is not a preference just for this project, but I wish to have some kind of future in graphics develepment, so I want to pick a platform that is future-safe. As for the game development in general, what should I take into consideration? I have never done a real game before, so any and all advise to development of mid-scale projects( if this would be a mid-scale project ) is greatly appreciated. My main concerns are the pit-falls and demotivators. Sorry if the question is so vague. If it doesn't belong here, then I will remove it. Otherwise, any and all advise regarding making larger projects is greatly appreciated.

  • Javascript scope chain

    - by Geromey
    Hi, I am trying to optimize my program. I think I understand the basics of closure. I am confused about the scope chain though. I know that in general you want a low scope (to access variables quickly). Say I have the following object: var my_object = (function(){ //private variables var a_private = 0; return{ //public //public variables a_public : 1, //public methods some_public : function(){ debugger; alert(this.a_public); alert(a_private); }; }; })(); My understanding is that if I am in the some_public method I can access the private variables faster than the public ones. Is this correct? My confusion comes with the scope level of this. When the code is stopped at debugger, firebug shows the public variable inside the this keyword. The this word is not inside a scope level. How fast is accessing this? Right now I am storing any this.properties as another local variable to avoid accessing it multiple times. Thanks very much!

  • GLOBAL loading inside each single button with Jquery in ajax calls of asp.net mvc

    - by Ricky
    I have the following scenario: I have a button\link with a image inside like this: <button type="submit" id="myButton" class="button"><img src="../../Content/images/check.png" id="defaultImage" /> SaveData!!!</button> We are OK here! Now what I need to do is: I want on the click that the image change for a loading element that is previously loaded in the page like this: <img id="loadingImage" src="../../Content/images/loader.gif" style="display: none;" alt="loading"/> And then when the load complete turn back the old button image, I ended with this code: function loader() { var $button = $('#myButton'); if (btnState == '1') { $button.find('img').hide(); $button.prepend($('#loadingImage')); $('#loadingImage').css({ 'display': 'inherit' }); btnState = '0'; } else { $button.find('img').hide(); $button.prepend($('#defaultImage')); $('#defaultImage').show(); btnState = '1'; } } This does the trick for ONE SINGLE button(since I pass its ID in the function) but, when I have for example a grid with a button on each line, I found inviable when managing a screen with many buttons do this for each of then. The main question is: How can I make this method general for all buttons/links on one specific class in the page? The goal is: Click a button, get the image and change it and stop(can be manual). I just don't wanna have to Hook ALL buttons.

  • Debug Symbols not loading

    - by FunkyFresh84
    I am trying to enable visual studio to step through the .net framework source code when I am debugging. I have tried with both Visual Web-Developer-Express-2010 and Visual-Studio-2011-Express-For-Web and I am getting the same problem with each. When I get to the break point at the .net method I wish to step into I do right-clickstep-into-specificclick-method-to-step-into. Then VS opens a new tab. saying it couldn't find or load the symbols. It gives a list of the assembly symbols it looked for. There is also a 'Load Symbols hyperlink which doesn't work. And another hyperlink that takes me to the debug settings dialog. I have read tutorials on how to set it up and have believe I have the correct settings. In the debugging general settings I have - enable address-level debugging - checked enable source server support - checked enable .net framework source stepping - checked enable just my code - not checked In the debugging symbol settings I have - symbol file (.pdb) locations - Microsoft Symbol Servers - checked Caching Directory - C:\Users\MyAccount\AppData\Local\Temp\SymbolCache Automatically load symbols for: all modules unless excluded - checked Why is it not working? Thank you for your help. edit: here is a screenshot of the error VS is giving me.

  • What's it like being a financial programmer?

    - by Mike
    As a student who's done an internship at a Silicon Valley company(non-financial), I'm curious to know what it's like working for a financial company doing software development. I'd expect the hours to be longer, and the pay to be higher. Specifically, I have the following questions: What's the work/life balance really like? Are you expected to work 80 hours a week most weeks? For those who have worked in non-financial software engineering jobs, how does being a financial software engineer compare in terms of work/life balance? How much does it pay? I'm curious as to starting(i.e. just got a BS) pay, as well as "top out" pay. (I'd prefer concrete numbers - ballpark is fine). Also, bonuses would be useful information. What jobs do financial programmers typically have? Are most just general software engineers, or do people typically have very specialized(i.e. AI or systems) backgrounds? Also, do most programmers have PhDs? Are programmers typically required to be at work, or are financial companies generally flexible about letting programmers work from home? When at work, do programmers have to dress formally? What are the technology environments like? Are finance companies using state-of-the-art hardware and software, or are they generally more conservative in upgrading their equipment? What programming languages are typically used? If VBA(shudder) is used, is it a large part of a finance company's workflow? If you could turn back the clock, would you still be a financial programmer? I'm going to keep this post open a little bit longer to get some more responses.

  • My Zend Framework 'quoting' mess.

    - by tharkun
    I've got a probably very simple issue to which I can't find a satisfactory (subjectively seen) answer in the Zend Framework manual or elsewhere... There are so many ways how I can hand over my php variables to my sql queries that I lost the overview and probably I lack some understanding about quoting in general. Prepared Statements $sql = "SELECT this, that FROM table WHERE id = ? AND restriction = ?"; $stmt = $this->_db->query($sql, array($myId, $myValue)); $result = $stmt->fetchAll(); I understand that with this solution I don't need to quote anything because the db handles this for me. Querying Zend_Db_Table and _Row objects over the API $users = new Users(); a) $users->fetchRow('userID = ' . $userID); b) $users->fetchRow('userID = ' . $users->getAdapter()->quote($userID, 'INTEGER')); c) $users->fetchRow('userID = ?', $userID); d) $users->fetchRow('userID = ?', $users->getAdapter()->quote($userID, 'INTEGER')); Questions I understand that a) is not ok because it's not quoted at all. But what about the other versions, what's the best? Is c) being treated like a statement and automatically quoted or do I need to use d) when I use the ? identifier?

  • Using perl to split a line that may contain whitespace

    - by Tommy Fisk
    Okay, so I'm using perl to read in a file that contains some general configuration data. This data is organized into headers based on what they mean. An example follows: [vars] # This is how we define a variable! $var = 10; $str = "Hello thar!"; # This section contains flags which can be used to modify module behavior # All modules read this file and if they understand any of the flags, use them [flags] Verbose = true; # Notice the errant whitespace! [path] WinPath = default; # Keyword which loads the standard PATH as defined by the operating system. Append with additonal values. LinuxPath = default; Goal: Using the first line as an example "$var = 10;", I'd like to use the split function in perl to create an array that contains the characters "$var" and "10" as elements. Using another line as an example: Verbose = true; # Should become [Verbose, true] aka no whitespace is present This is needed because I will be outputting these values to a new file (which a different piece of C++ code will read) to instantiate dictionary objects. Just to give you a little taste of what it might look like (just making it up as I go along): define new dictionary name: [flags] # Start defining keys => values new key name: Verbose new value val: 10 # End dictionary Oh, and here is the code I currently have along with what it is doing (incorrectly): sub makeref($) { my @line = (split (/=/)); # Produces ["Verbose", " true"]; }

  • Map large integer to a phrase

    - by Alexander Gladysh
    I have a large and "unique" integer (actually a SHA1 hash). I want (for no other reason than to have fun) to find an algorithm to convert that SHA1 hash to a (pseudo-)English phrase. The conversion should be reversible (i.e., knowing the algorithm, one must be able to convert the phrase back to SHA1 hash.) The possible usage of the generated phrase: the human readable version of Git commit ID, like a motto for a given program version (which is built from that commit). (As I said, this is "for fun". I don't claim that this is very practical — or be much more readable than the SHA1 itself.) A better algorithm would produce shorter, more natural-looking, more unique phrases. The phrase need not make sense. I would even settle for a whole paragraph of nonsense. (Though quality — englishness — of a paragraph should probably be better than for a mere phrase.) A variation: it is OK if I will be able to work only with a part of hash. Say, first six digits is OK. Possible approach: In the past I've attempted to build a probability table (of words), and generate phrases as Markov chains, seeding the generator (picking branches from probability tree), according to the bits I read from the SHA. This was not very successful, the resulting phrases were too long and ugly. I'm not sure if this was a bug, or the general flaw in the algorithm, since I had to abandon it early enough. Now I'm thinking about attempting to solve the problem once again. Any advice on how to approach this? Do you think Markov chain approach can work here? Something else?

  • What is the relationship between Turing Machine & Modern Computer ?

    - by smwikipedia
    I heard a lot that modern computers are based on Turing machine. I just cannot build a bridge from a conceptual Turing Machine to a real modern computer. Could someone help me build this bridge? Below is my current understanding. I think the computer is a big general-purpose Turing machine. Each program we write is a small specific-purpose Turing machine. The classical Turing machine do its job based on the input and its current state inside and so do our programs. Let's take a running program (a process) as an example. We know that in the process's address space, there's areas for stack, heap, and code. A classical Turing machine doesn't have the ability to remember many things, so we borrow the concept of stack from the push-down automaton. The heap and stack areas contains the state of our specific-purpose Turing machine (our program). The code area represents the logic of this small Turing machine. And various I/O devices supply input to this Turing machine.

  • Strange error when filling a data adapter.

    - by Tim C
    I am receiving the following error in my code (c#, .Net 3.5, VS2008) when I try to connect to an Excel sheet and fill a OleDbDataAdapter with the results of a query. First the error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. And here is the code, which is honestly pretty simple: var excelFileName = string.Format("c:/Metadata_Tool.xlsm"); var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0; Data Source={0}; Extended Properties=Excel 12.0;HDR=YES;", excelFileName); var adapter = new OleDbDataAdapter("Select * FROM [Video Tagging XML]", connectionString); var ds = new DataSet(); adapter.Fill(ds, "VTX"); DataTable data = ds.Tables["VTX"]; foreach (DataRow myRow in data.Rows) { foreach (DataColumn myColumn in data.Columns) { Console.Write("\t{0}", myRow[myColumn]); } Console.WriteLine(); } Console.ReadLine(); I get the error on the line adapter.Fill(ds,"VTX");. I did find a microsoft forum post saying to turn on JIT optimization in VS2008 from the Tools/Options/Debug/General menu, but this did not seem to help. Any help would be greatly appreciated thanks!

  • XPath with optional tbody element

    - by Phrogz
    As in this Stack Overflow answer imagine that you need to select a particular table and then all the rows of it. Due to the permissiveness of HTML, all three of the following are legal markup: <table id="foo"><tr>...</tr></table> <table id="foo"><tbody><tr>...</tr></tbody></table> <table id="foo"><tr>...</tr><tbody><tr>...</tr></tbody></table> You are worried about tables nested in tables, and so don't want to use an XPath like table[@id="foo"]//tr. If you could specify your desired XPath as a regex, it might look something like: table[@id="foo"](/tbody)?/tr In general, how can you specify an XPath expression that allows an optional element in the hierarchy of a selector? To be clear, I'm not trying to solve a real-world problem or select a specific element of a specific document. I'm asking for techniques to solve a class of problems.

  • Replicating SQL's 'Join' in Python

    - by Daniel Mathews
    I'm in the process of trying to switch from R to Python (mainly issues around general flexibility). With Numpy, matplotlib and ipython, I've am able to cover all my use cases save for merging 'datasets'. I would like to simulate SQL's join by clause (inner, outer, full) purely in python. R handles this with the 'merge' function. I've tried the numpy.lib.recfunctions join_by, but it critical issues with duplicates along the 'key': join_by(key, r1, r2, jointype='inner', r1postfix='1', r2postfix='2', defaults=None, usemask=True, asrecarray=False) Join arrays r1 and r2 on key key. The key should be either a string or a sequence of string corresponding to the fields used to join the array. An exception is raised if the key field cannot be found in the two input arrays. Neither r1 nor r2 should have any duplicates along key: the presence of duplicates will make the output quite unreliable. Note that duplicates are not looked for by the algorithm. source: http://presbrey.mit.edu:1234/numpy.lib.recfunctions.html Any pointers or help will be most appreciated!

  • How best to use XPath with very large XML files in .NET?

    - by glenatron
    I need to do some processing on fairly large XML files ( large here being potentially upwards of a gigabyte ) in C# including performing some complex xpath queries. The problem I have is that the standard way I would normally do this through the System.XML libraries likes to load the whole file into memory before it does anything with it, which can cause memory problems with files of this size. I don't need to be updating the files at all just reading them and querying the data contained in them. Some of the XPath queries are quite involved and go across several levels of parent-child type relationship - I'm not sure whether this will affect the ability to use a stream reader rather than loading the data into memory as a block. One way I can see of making it work is to perform the simple analysis using a stream-based approach and perhaps wrapping the XPath statements into XSLT transformations that I could run across the files afterward, although it seems a little convoluted. Alternately I know that there are some elements that the XPath queries will not run across, so I guess I could break the document up into a series of smaller fragments based on it's original tree structure, which could perhaps be small enough to process in memory without causing too much havoc. I've tried to explain my objective here so if I'm barking up totally the wrong tree in terms of general approach I'm sure you folks can set me right...

  • Suppress Eclipse compiler errors in in a plug-in

    - by Jan Gorzny
    Hi, I'm currently working on a plug-in for Eclipse that translates some custom Java code (which doesn't necessarily run/compile), to runnable Java code. In particular, the plug-in allows code to be written using classes created or imported during the translation. In general, the pre-translation code runs/compiles fine provided the writer uses import statements at the top of their class files. However, it would be convenient for my users if it was not necessary to import these classes. At the moment, the lack of import statements results in (obvious) compiler errors. Would it be possible to empower my plug-in to either a) suppress/ignore these errors, or b) have Eclipse find these classes automatically, without the use of import statements? I should point out that the translated code would these include the required import statements--but this is not a problem for me. I'm also aware that this could lead to lazy programmers and some bad habits. To clarify, consider the following example of pre-translated code: File f = new File("Somefilename.txt"); which clearly requires the possibly imported class File. Without an import statement (import java.io.File;), Eclipse reports that File can not be resolved to a type. This is the error I'd like to hide in files pertaining to projects created for use with my plug-in. (The translated code would include import java.io.File; so that it would be runnable) In closing, I should point out I'm not necessarily looking for code (though I wouldn't be opposed to it), but rather some links to some relevant tutorials (if they exist), or helpful tips/ideas. Also, as this is my first plug-in, it's entirely possible that what I'd like to do is not possible and that I don't realize it--if this is the case, please let me know, preferably with some justification. Thanks!

  • PHP (A few questions) OO, refactoring, eclipse

    - by jax
    I am using PHP in eclipse. It works ok, I can connect to my remote site, there is colour coding of code elements and some code hints. I realise this may be too long to answer all questions, if you have a good answer for one part, answering just that is ok. Firstly General Coding I have found that it is easy to loose track of included files and their variables. For example if there was a database $cursor it is difficult to remember or even know that it was declared in the included file (this becomes much worse the more files you include). How are people dealing with this? How are people documenting their code - in particular the required GET and POST data? Secondly OO Development: Should I be going full OO in my development. Currently I have a functions library which I can include and have separated each "task" into a separate file. It is a bit nasty but it works. If I go OO how do I structure the directories in PHP, java uses packages - what about php? How should I name my files, should I use all lower case with _ for spaces "hello_world.php"? Should I name classes with Uppercase like Java "HelloWorld.php"? Is there a different naming convention for Classes and regular function files? Thirdly Refactoring I must say this is a real pain. If I change the name of a variable in one place I have to go through whole document and each file that included this file and change the name their too. Of course, errors everywhere is what results. How are people dealing with this problem? In Java if you change the name in one place it changes everywhere. Are there any plugins to improve php refactoring? I am using the official PHP version of Eclipse from their website. thanks

  • Mercurial Hg Clone fails on C# project with GUID

    - by AnneTheAgile
    UPDATE: In trying to replicate this problem one more time to answer your questions I could not! I can only conclude that my initial setup of Mercurial was problematic and/or possibly I was trying to checkin a build that failed compilation before the checkin. Sigh! Thank you so very much for your help. I gave credit for the help on how to do a script. I need to try that for general purposes. hi all, I hope you can help me :). I am trying to see if Mercurial would be a good DCVS for my project at work, and I'm surely a newbie to many things. We have a fairly large codebase in C# (Dotnet3.0 not 3.5 , WindowsXP) and it utilizes the GUID feature. I confess to know little about how or why we use the GUID, but I do know that I cannot touch it. So, when I try hg clone, it fails unless I change the GUID in the cloned directory (ie create new GUID in Visual Studio and then paste that new GUID to replace the old one). To me, this completely defeats the purpose and utility of quick easy clones. It also makes difficult all the many workflows that require multiple clones. Is there a workaround, or is there something I'm doing wrong? How can I simplify and/or remove this problem? Would Bazaar make this easier? Thank you!

  • How can I do batch image processing with ImageJ in Java or clojure?

    - by Robert McIntyre
    I want to use ImageJ to do some processing of several thousand images. Is there a way to take any general imageJ plugin and apply it to hundreds of images automatically? For example, say I want to take my thousand images and apply a polar transformation to each--- A polar transformation plugin for ImageJ can be found here: http://rsbweb.nih.gov/ij/plugins/polar-transformer.html Great! Let's use it. From: [http://albert.rierol.net/imagej_programming_tutorials.html#How%20to%20automate%20an%20ImageJ%20dialog] I find that I can apply a plugin using the following: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" ""))) This is good because it suppresses the dialog which would otherwise pop up for every image. But running this always brings up a window containing the transformed image, when what I want is to simply return the transformed image. The stupidest way to do what I want is to just close the window that comes up and return the image which it was displaying. Does what I want but is absolutely retarded: (defn x-polar [imageP] (let [thread (Thread/currentThread) options ""] (.setName thread "Run$_polar-transform") (Macro/setOptions thread options) (IJ/runPlugIn imageP "Polar_Transformer" "") (let [return-image (IJ/getImage)] (.hide return-image) return-image))) I'm obviously missing something about how to use imageJ plugins in a programming context. Does anyone know the right way to do this? Thanks, --Robert McIntyre
