  • Median Filter a bi-level image with JAI

    - by Mark
    I'd like to apply a Median Filter to a bi-level image and output a bi-level image. The JAI median filter seems to output an RGB image, which I'm having trouble downconverting back to bi-level. Currently I can't even get the image back into gray color-space, my code looks like this: BufferedImage src; // contains a bi-level image ParameterBlock pb = new ParameterBlock(); pb.addSource(src); pb.add(MedianFilterDescriptor.MEDIAN_MASK_SQUARE); pb.add(3); RenderedOp result = JAI.create("MedianFilter", pb); ParameterBlock pb2 = new ParameterBlock(); pb2.addSource(result); pb2.add(new double[][]{{0.33, 0.34, 0.33, 0}}); RenderedOp grayResult = JAI.create("BandCombine", pb2); BufferedImage foo = grayResult.getAsBufferedImage(); This code hangs on the grayResult line and appears not to return. I assume that I'll eventually need to call the "Binarize" operation in JAI. Edit: Actually, the code appears to be stalling once I call getAsBufferedImage(), but returns nearly instantly when the second operation ("BandCombine") is removed. Is there a better way to keep the Median Filtering in the source color domain? If not, how do I downconvert back to binary?

  • Ubuntu 10.04 (Lucid) OpenLDAP invalid credentials issue

    - by gmuller
    This won't be a question, but a solution to an infuriating problem on Ubuntu 10.04. If you tried to deploy an LDAP server using this distro following the tutorials below, you'll be on serious trouble. Tutorials: https://help.ubuntu.com/9.10/serverguide/C/openldap-server.html https://help.ubuntu.com/9.10/serverguide/C/samba-ldap.html The error first appear, on the line: "ldapsearch -xLLL -b cn=config -D cn=admin,cn=config -W olcDatabase=hdb olcAccess" It simply won't allow admin to access the "cn=config", thus you won't be able to deploy the LDAP server correctly. After almost a week searching for a solution, I've found this page: https://bugs.launchpad.net/ubuntu-docs/+bug/333733 On comment #5, the solution is presented. Quoting the author: when you get to the setting up ACL part you all of a sudden need to use a cn=admin,cn=config, that doesn't exist creating a config.ldif with dn: olcDatabase={0}config,cn=config changetype: modify add: olcRootDN olcRootDN: cn=admin,cn=config dn: olcDatabase={0}config,cn=config changetype: modify add: olcRootPW olcRootPW: secret dn: olcDatabase={0}config,cn=config changetype: modify delete: olcAccess and adding it with ldapadd -Y EXTERNAL -H ldapi:/// -f config.ldif It's unacceptable that a Linux distribution, popular like Ubuntu, have such ridiculous bug. Hope it helps everyone!

  • AutoMapper a viable alternative to two way databinding using a FormView?

    - by tbone
    I've started using the FormView control to enable two way databinding in asp.net webforms. I liked that it saved me the trouble of writing loadForm and unloadForm routines on every page. So it seemed to work nicely at the start when I was just using textboxes everywhere....but when it came time to start converting some to DropDownLists, all hell broke lose. For example, see: http://stackoverflow.com/questions/2435185/not-possible-to-load-dropdownlist-on-formview-from-code-behind ....and I had many additional problems after that. So I happened upon an article on AutoMapper, which I know very little about yet, but from the sounds of it, this might be a viable alternative to two-way databinding a form to an domain entity object? From what I understand, AutoMapper basically operates on naming convention, so, it will look for matched names properties(?) on the source and destination objects. So, basically, I have all my domain entities (ie: Person) with properties (FirstName, LastName, Address, etc)....what I would like to be able to do is declare my asp controls with those exact same names, and have automapper do the loading and unloading. One obvious caveat is that AutoMapper would have to know the proper property name for each control type, ie: Person.FirstName -- form.FirstName*.Text* Person.Country -- form.Country.SelectedValue Person.IsVerified -- form.IsVerified.Checked ....so it would have to have the smarts to find the control on the form, determine its type, and then load/unload between the domain object and the webform control into the proper property of the control. So if this worked, a person could just get rid of the cursed FormView control entirely, and it would be just one line of code each for binding and unbinding a webform. Possible?

    Hi. I have ceated several django apps and stuffs for my own fund and so far everything has been working fine. Now i just created new project (django 1.2.1) and have run into trouble from 1st moments. I created new app - game and new model Game. i created admin.py and put related stuff into it.

  • MySQL Relational Database Foreign Key

    - by user623879
    To learn databasing, I am creating a movie database. To associate multiple directors with a movie, I have the following schema: movie(m_ID, ....) m_director(dirID, dirName)//dirID is a autoincrement primary key m_directs(dirID, m_ID) //dirID, m_ID are set as foreign Keys in the mysql database(InnoDB engine) I have a program that connects to the db that needs to add a movie to the database. I can easily add a new entry to the movie table and the m_director table, but I am having trouble adding a entry in the m_directs table. INSERT INTO m_director (dirName) VALUES("Jason Reitman"); INSERT INTO m_directs (dirID, m_ID) VALUES(LAST_INSERT_ID(), "tt0467406"); I am using this sql statement to insert a new director and add the association to the movie. I know the primary key of the movie, but I don't know the dirID, so I use LAST_INSERT_ID() to get the last id of the director just inserted. The problem I am having is that I get the following error: MySql.Data.MySqlClient.MySqlException (0x80004005): Cannot add or update a child row: a foreign key constraint fails (`siteproducts`. `m_directs`, CONSTRAINT `m_directs_ibfk_2` FOREIGN KEY (`dirID`) REFERENCES `m_directs` (`dirID`) ON DELETE CASCADE ON UPDATE CASCADE) Any ideas?

  • Poco SocketReactors for a Proxy Server

    - by Genesis
    Can anyone give me some idea of the best way to implement a non-blocking proxy server using a Poco Socket Reactor? Currently I have a blocking implementation where if a readable notification arrives from the client I am writing what is read directly to the server, and if a readable notification arrives from the server I am writing what is read directly to the client. To achieve this I keep the thread that initiated the server connection alive but I would prefer to switch to non-blocking and have any threads which are used to initiate a connection removed once the server and client sockets are registered with the reactor and the SOCKS5 handshake is over. With a SocketReactor one can register event handlers for a single socket but the trouble is I would need to store whatever is read from that socket in a global buffer until the corresponding server socket is ready to be written to as from my testing I dont seem to be able to just write directly to the server when client data arrives. I am thinking of using a struct that contains the client socket, server socket, client buffer and server buffer and whenever a writable notification comes along for either the client or server, finding the corresponding buffer and writing this. Any thoughts?

  • Usercontrol losing Viewstate across Postback

    - by Robert W
    I have a user control which uses objects as inner properties (some code is below). I am having trouble with setting the attribute of the Step class programmatically, when set programmatically it is being lost across postback which would indicate something to do with Viewstate (?).

  • Why is document.body == null in Firefox but not Safari

    - by dlamblin
    I have a problem with a page where I am trying to get colorbox (a kind of lightbox for jQuery) working. It doesn't work apparently due to the document.body being null in FireFox (3.5.3). This is not the case in Safari (4.0.3) where the colorbox works. Something that jumps out at me is that (I'm using Drupal 6) drupal has appended a script tag to set some JavaScript variables at the very bottom of the page, below the closing body and html tags. Otherwise I don't see a problem. Unfortunately I'm having a lot of trouble getting it not to do that. Could it be this that's causing FF to have issues with the body? Using colorbox's example files in Firefox does work (and the document.body is defined there). Is there any way I could use jQuery to refill the document.body property with something from $() perhaps, or should I keep banging at drupal to not put a script tag outside the html tags (easier said than done)? To clarify the document.body is null even after the page is done loading. Here's a Firebug console capture: >>> document.body null >>> $().attr('body') null

  • extracting RDL data using LINQ

    - by BobC
    I'm working with some SQL Report definition files (RDLs), using LINQ to extract component query statements for validation. I'm trying to extract the <DataSet> elements from under the <DataSets> element. I seem to be getting hung up with one of the elements under <DataSet><Fields><Field> which has a namespace qualifier <rd:TypeName> I've been using LINQ to XML for other parts of the files where there is no namespace qualifiers with no trouble, by specifying a default namespace. The RDL specifies two namespaces: xmlns="http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner"> When I try to get the <DataSets> element, however, I get the following error: System.Xml.XmlException - The ':' character, hexadecimal value 0x3A, cannot be included in a name. I know it has to do with the namespace qualifier (rd:) in one of the child elements, but I'm having difficulty getting a LINQ expression that works. Any help would be appreciated. Thanks!

  • Microsoft Surface - Flip & Scatter View Items

    - by Angelus
    Hi Guys, I'm currently trying to get flip to work with scatterview items, and I'm having some trouble conceptually with it, using a plugin called Thriple (http://thriple.codeplex.com/). Essentially, a 2 sided thriple control looks like this: <thriple:ContentControl3D xmlns:thriple="http://thriple.codeplex.com/" Background="LightBlue" BorderBrush="Black" BorderThickness="2" MaxWidth="200" MaxHeight="200" > <thriple:ContentControl3D.Content> <Button Content="Front Side" Command="thriple:ContentControl3D.RotateCommand" Width="100" Height="100" /> </thriple:ContentControl3D.Content> <thriple:ContentControl3D.BackContent> <Button Content="Back Side" Command="thriple:ContentControl3D.RotateCommand" Width="100" Height="100" /> </thriple:ContentControl3D.BackContent> </thriple:ContentControl3D> What I'm struggling to grasp is if I should be making 2 separate ScatterView templates to bind to the data I want, and then each one would be the "front" and "back" of a scatterview item OR should i make 2 separate ScatterView items which are bound to the data I want, which is then bound to the "back" and "front" of a main ScatterView item? If there is a better way of using doing flip animations with ScatterViewItem's, that'd be cool too! Thanks!

  • Example of testing a RPC call using GWT-TestCase with GAE

    - by Stephen Cagle
    How is that for a lot of acronyms! I am having trouble testing GWT's RPC mechanism using GWT's GWTTestCase. I created a class for testing using the junitCreator tool included with GWT. I am attempting to test using the built in Google App Engine using the created "hosted mode" testing profile created by junitCreator. When I run the test, I keep getting errors saying things like Starting HTTP on port 0 HTTP listening on port 49569 The development shell servlet received a request for 'greet' in module 'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml' [WARN] Resource not found: greet; (could a file be missing from the public path or a <servlet> tag misconfigured in module com.google.gwt.sample.stockwatcher.StockWatcher.JUnit.gwt.xml ?) com.google.gwt.user.client.rpc.StatusCodeException: Cannot find resource 'greet' in the public path of module 'com.google.gwt.sample.stockwatcher.StockWatcher.JUnit' I hope that someone somewhere has successfully run junit test (using GWTTestCase or just plain TestCase) that will allow for the testing of gwt RPC. If this is the case, could you please mention the steps you took, or better yet, just post code that works. Thanks.

  • How to fix IE ClearType + jQuery opacity problem in this script?

    - by Justine
    Hello, I'm having a rather common problem (or so it seems, after some googling around...) with IE messing both bold text AND transparent pngs while animating opacity using jQuery. You can view the sample here: http://dev.gentlecode.net/dotme/index-sample.html (only occurs in IE, obviously) I've seen some blog posts saying the fix is to remove the filter attribute but I'm not sure how to apply it to the script I'm using since I got it from a tutorial and am still learning jQuery... The script goes as follows: $('ul.nav').each(function() { var $links = $(this).find('a'), panelIds = $links.map(function() { return this.hash; }).get().join(","), $panels = $(panelIds), $panelWrapper = $panels.filter(':first').parent(), delay = 500; $panels.hide(); $links.click(function() { var $link = $(this), link = (this); if ($link.is('.current')) { return; } $links.removeClass('current'); $link.addClass('current'); $panels.animate({ opacity : 0 }, delay); $panelWrapper.animate({ height: 0 }, delay, function() { var height = $panels.hide().filter(link.hash).show().css('opacity', 1).outerHeight(); $panelWrapper.animate({ height: height }, delay); }); return false; }); var showtab = window.location.hash ? '[hash=' + window.location.hash + ']' : ':first'; $links.filter(showtab).click(); }); I would appreciate if someone could go over it and show me how to fix the opacity issue. Will the filter method also fix the trouble I'm having with transparent pngs having pixelated ugly borders like the bold type as well? Thanks in advance for all help!

  • Flex AdvancedDataGrid - ColumnOrder With Formatter and ItemRenderer Question For Experts

    - by robin1126
    I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below. The number columns have formatting done for zero precision and 2 digits precision. The itemRenderer is just to show Blue Color if the number is +ve and Red Color if the number is -ve. It looks something like below ... I am trying to save the users setting of column order when he closes the application and reload with the same order when the user opens the applications. I am using SharedObjects and below is the code. for(var i:int=0; i< adgrid.columns.length;i++){ var columnObject:Object = new Object(); columnObject.columnDataField = adgrid.columns[i].dataField as String; columnObject.columnHeader =adgrid.columns[i].headerText as String; columnObject.width = adgrid.columns[i].width; columnArray.push(columnObject); } and then I save the columnArray to SharedObject. I retrive them using the below code for(var i:int=0;i adgrid.columns[i].dataField =columnArray[i].columnDataField; adgrid.columns[i].headerText =columnArray[i].columnHeader; adgrid.columns[i].width = columnArray[i].width; } How can I save and reload the Formatter and ItemRenderer data . I am having trouble saving the formatter and itemrenderer and reloading it again. I would really appreciate if you can shown the code. How can I reshuffle the columns but can preserve all the properties of it to the sharedobject and recover it again.

Basically, what I'm after is something like the Task pane in an MMC: The app has three columns in the main part of the display. I need a column on the right side which is resizable. I presume this means using a Grid with a GridSplitter but anything that works will do. I want to be able to save the width of the right-side column when the app is closed and load it when the app is opened but this should be an initial size: the user should be able to resize it. When I resize the window, I want the left- and right-side columns to stay the same size and the middle column to resize with the window width. The left- and right-side columns need to have a minimum width. When I resize the right-side column I want the centre column to get smaller but not the left-side column. I also want to be able to toggle the visibility of the right-side column with a toggle button which is outside the column and when it returns to visibility I want it to be the same width it was before. I'm trying to do as much as possible in XAML and with binding. And can I have it topped with cream, ice cream and chocolate chips, please? :-)

  • Parsing XML via jQuery, nested loops

    - by Coughlin
    I am using jQuery to parse XML on my page using $.ajax(). My code block is below and I can get this working to display say each result on the XML file, but I am having trouble because each section can have MORE THAN ONE and im trying to print ALL grades that belong to ONE STUDENT. Here is an example of the XML. <student num="505"> <name gender="male">Al Einstein</name> <course cid="1">60</course> <course cid="2">60</course> <course cid="3">40</course> <course cid="4">55</course> <comments>Lucky if he makes it to lab, hopeless.</comments> </student> Where you see the I am trying to get the results to print the grades for EACH student in each course. Any ideas on what I would do? Thanks, Ryan $.ajax({ type: "GET", url: "final_exam.xml", dataType: "xml", success: function(xml) { var student_list = $('#student-list'); $(xml).find('student').each(function(){ $(xml).find('course').each(function(){ gradeArray = $(this).text(); console.log(gradeArray); }); var name = $(this).find("name").text(); var grade = $(this).find("course").text(); var cid = $(this).find("course").attr("cid"); //console.log(cid); student_list.append("<tr><td>"+name+"</td><td>"+cid+"</td><td>"+grade+"</td></tr>"); }); } });

  • Autocomplete extender problems on user control

    - by RUtt
    I'm having trouble getting autocompleteextender (from ajaxcontroltoolkit) to fire when it is on a user control (it works fine when everything is on an aspx page. In my case I'm using a master page as well as a user control. Here's what I have. On the masterpage (path: masterpages/MasterPage.master) <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnablePageMethods="true"> </asp:ToolkitScriptManager> On the user control (path: controls/sitenavigation/usercontrol.ascx) <asp:TextBox id="txtSearchInput" Runat="server" CssClass="searchinput" Columns="95" MaxLength="95"></asp:TextBox> <asp:AutoCompleteExtender ID="txtSearchInput_AutoCompleteExtender" runat="server" DelimiterCharacters="" Enabled="True" ServiceMethod="GetSuggestions" ServicePath="~/App_Code/WebService.asmx" TargetControlID="txtSearchInput" UseContextKey="False" MinimumPrefixLength="2"> </asp:AutoCompleteExtender> On the Webservice (path: App_Code/WebService.cs) [System.Web.Script.Services.ScriptService] public class WebService : System.Web.Services.WebService { .... [WebMethod] public string[] GetSuggestions(string prefixText, int count, string contextKey) { //my code to return string[] } It seems that my problem is with my ServicePath in the extender but I just can't seem to figure out what it should be, any help would be great. Thanks.

  • C# IsolatedStorage Not Working

    - by Don
    I am building a C# .NET (VS2010) IE8 add-on application but am having some trouble saving data using IsolatedStorage. No exceptions occur but, after writing the data, when I try to read the contents back it is blank, and I can find no evidence that it actually saved. Could anyone point out any problems with the following code please that would explain why it doesn't work? //Write IsolatedStorageFile app_isoStore = IsolatedStorageFile.GetStore( IsolatedStorageScope.User | IsolatedStorageScope.Assembly, null, null); IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream( "app_started.txt", FileMode.OpenOrCreate, FileAccess.Write, app_isoStore); StreamWriter iswriter = new StreamWriter(isoStream); iswriter.WriteLine("Run"); iswriter.Close(); //app_isoStore.Dispose(); app_isoStore.Close(); //Read IsolatedStorageFile app_isoStoreCheck = IsolatedStorageFile.GetStore( IsolatedStorageScope.User | IsolatedStorageScope.Assembly, null, null); IsolatedStorageFileStream isoReadStream = new IsolatedStorageFileStream( "app_started.txt", FileMode.Open, FileAccess.Read, app_isoStoreCheck); StreamReader isreader = new StreamReader(isoReadStream); string rdata = isreader.ReadToEnd(); isreader.Close(); //app_isoStoreCheck.Dispose(); app_isoStoreCheck.Close(); Should I be using: IsolatedStorageFile.GetStore(IsolatedStorageScope.User| IsolatedStorageScope.Domain|IsolatedStorageScope.Assembly, null,null) instead of: IsolatedStorageFile.GetStore(IsolatedStorageScope.User| IsolatedStorageScope.Assembly, null, null) What's the difference between the two GetStore examples above please?

  • How to best handle exception to repeating calendar events

    - by blcArmadillo
    I'm working on a project that will require me to implement a calendar. I'm trying to come up with a system that is very flexible: can handle repeating events, exceptions to repeats, etc. I've looked at the schema for applications like iCal, Lotus Notes, and Mozilla to get an idea of how to go about implementing such a system. Currently I'm having trouble deciding what is the best way to handle exceptions to repeating events. I've used databases quite a bit but don't have a ton of experience with really optimizing everything so I'm not sure which method of the two I'm considering would be optimal in terms of overall performance and ability to query/search: Breaking the repeating event. So taking the changing the ending date on the current row for the repeating event, inserting a new row with the exception, and adding another row continuing the old sequence. Simply adding an exception. So adding a new row with some field that indicates it as an override. So here is why I can't decide. Method one will result in a lot more rows since each edit requires 2 extra rows as apposed to only one row by the second method. On the other hand I think the query to find an event would be much simper, and thus possibly faster(?) using the first method. The second method seems like it will require more calculating on the application server since once you get the data you'll have to remove the intersection of the two rows. I know databases are often the bottleneck for websites and while I'm sure a lot of you are thinking either is fine because your project will probably never get large enough for the difference in efficiency to really matter, I'd still like to implement the best solution. So what method would you guys pick, or would you do something completely different? Also, as a side note I'll be using MySQL and PHP. If there is another technology that you think would be better suited for this, especially in the database area, please mention it. Thanks for the advice.
