• PBKDF2-HMAC-SHA1

  - by Jason

  To generate a valid pairwise master key for a WPA2 network a router uses the PBKDF2-HMAC-SHA1 algorithm. I understand that the sha1 function is performed 4096 times to derive the PMK, however I have two questions about the process. Excuse the pseudo code. 1) How is the input to the first instance of the SHA1 function formatted? SHA1("network_name"+"network_name_length"+"network_password") Is it formatted in that order, is it the hex value of the network name, length and password or straight ASCII? Then from what I gather the 160 bit digest received is fed straight into another round of hashing without any additional salting. Like this: SHA1("160bit digest from last round of hashing") Rise and repeat. 2) Once this occurs 4096 times 256 bits of the output is used as the pairwise master key. What I don't understand is that if SHA1 produces 160bit output, how does the algorithm arrive at the 256bits required for a key? Thanks for the help.

• CruiseControl: How to read logs from exec task

  - by Marty

  I start an external groovy script via cruisecontrol, which basically works. My problem is that if the groovy script fails I only get the "error string found" in my cruise webapp and email; its even not in the log files. The groovy script writes it output to stdout and to a logfile. How it is possible to display the output of an external script in the cruisecontrol logs? <project name="proj"> <schedule> <exec workingdir="/myscripts/folder" command="//bin/groovy" args="build.groovy -p ${project.name}.properties" errorstr="Exception"/> </schedule> </project>

• Perl - Internal File (create and execute)

  - by drewrockshard

  I have a quick question about creating files with perl and executing them. I wanted to know if it was possible to generate a file using perl (I actually need a .bat script) and then execute this file internally to the program. I know I can create files, and I have with perl, however, I'm wanting to do this internally to the program. So, what I want it to do is actually create a batch script internally to the program (no file is actually written to the disk, everything remains in memory, or the perl program), and then once it completes the writing of the file, I'd like to be able to actually execute this file, and then discard the file it just wrote. I'm basically trying to have it create a batch script on the fly, so that I can just have output text files from the output of the script, rather than creating the batch script on disk, then executing it, and then deleting the batch file from disk when its done. Can this be done and how would I go about doing this? Regards, Drew

• Dividing a Video into Frames and Sending Frames to Streams

  - by Amit Kumar

  I have to implement a "demux" that divides up a video stream and sends each frame to one of multiple output streams in a round-robin fashion. I am trying to implement the demux as follows. The video stream contains one frame after another and is implemented via a java InputStream. Each frame has a frame header followed by the image data. The demux needs to read the frame header to know the size of the image data. The image data can then be redirected from the input video stream to one of the output streams (java OutputStream). My problem is about how to implement this redirection. That is, connect the InputStream to the OutputStream to send N bytes (here N is the size of the image data), and then disconnect and connect to another OutputStream. I have seen the interface of PipedInputStream etc but they do not seem to implement the disconnection.

• what perl regex should I use to get value from line

  - by Octopus

  I am trying to capture the cpu usage from the running process. For SunOS, I have below output process,10050,user1,218,59,0,1271M,1260M,sleep,58.9H,0.02%,java here the cpu % is at 11th field if we separate by comma(,). To get this value I am using below regex regex => q/^process,(?:.*?),((?:\d+)\.(?:\d+))%,java$/, but for the linux system I have below output. process,26190,user1,20,0,1236m,43m,6436,S,0.0,1.1,0:00.00,java, here the cpu usage is at 10th column What regex pattern should i use to get this value. Appreciate for any suggestion.

• Debug.WriteLine not working

  - by Velika

  In the past, perhaps versions of Visual Studio prior to the 2008 that I am using now, I would do something like this in my VB.NET code: System.Diagnostics.Debug.WriteLine("Message") ..and the output would go to the output window. Now it doesn't. Something must first apparently be enabled. If this involves "attaching a debugger", please explain how to do it. It seems to me that it should just work without too much of a fuss. Here's a video explaining the issue in real time and showing you all my settings http://screencast.com/t/YQnPb0mJcs I'm using VS2008

• Value Comparison with a multivalued column in SQL Database Table

  - by Rishabh Ohri

  Hi All, Suppose there is a table A which has a column AccessRights which is multivalued( Eg of values in it in this format STOLI,HELP,BRANCH(comma separated string) Now a stored procedure is written against this table to fetch records based on a AccessRight parameter sent to the SP. Let that parameter be @AccessRights, this is also a comma separated string which may have a value like STOLI,BRANCH,HELPLINE etc Now I want to compare individual values from the parameter @AccessRights with the column AccessRights. Current Approach is I split the Comma Separated string(@AccessRights) using a User Defined Function Split. And I get Individual values in a Table variable(Contains only one column "accessGroup"), the individual values are in a Table variable under the column name accessGroup and I use following code in the SP for comparison Where AccessRights like '%'+accessGroup+'%' Now if the user passes the parameter (HELP, OLI) instead of( HELP,STOLI) the SP will give the output. What should be done for comparison so that that subststring OLI does not give the output for STOLI

• Convert a PDF to a Transparent PNG with GhostScript

  - by Jonathon Wolfe

  Hi all. I am attempting, unsuccessfully, to use Ghostscript to rasterize PDF files with a transparent background to PNG files with a transparent background. I've searched high and low for questions from others attempting the same thing and none of the posted solutions, which as far as I can tell come down to specifying -sDEVICE=pngalpha, have worked with my test files. At this point I would really appreciate any advice or tips a more experienced hand could provide. My test PDF is located here: http://www.kolossus.com/files/test.pdf It could be that the issue is with this file, but I doubt it. As far as I can tell, it has no specified background, and when I open the file with a transparency-aware app like Photoshop or Illustrator, sure enough it displays with a transparent background. However, when opened with an application like Adobe Reader the file is rendered with a white background. I believe that this has more to do with the application rendering the PDF than with the PDF itself -- apps like Adobe Reader assume you want to see what a printed document will look like and therefore always show a white canvas behind the artwork -- but I can't be sure. The gs command I'm using is: gs -dNOPAUSE -dBATCH -sDEVICE=pngalpha -r72 -sOutputFile=test.png test.pdf This produces a PNG that has transparent pixels outside of the bounding box of the artwork in the file, but all pixels that are inside the artwork's bounding box are rasterized against a white background. This is a problem for me, as my artwork has drop shadows and antialiased edges that need to be preserved in the final output, and can't just be postprocessed out with ImageMagick. A sample of my PNG output is at the same location as the pdf above, with .png at the end (stackoverflow won't let me include more than one url in my post). Interestingly, I see no effects from using the -dBackgroundColor flag, even if I set it to something non-white like -dBackgroundColor=16#ff0000. Perhaps my understanding of the syntax of this flag is wrong. Also interestingly, I see no effects from using the -dTextAlphaBits=4 -dGraphicsAlphaBits=4 flags to try to enable subpixel antialiasing. I would also appreciate any advice on how to enable subpixel antialiasing, especially on text. Finally, I'm using GPL Ghostscript 8.64 on Mac OS 10.5.7, and the rendering workflow I'm trying to get set up is to generate transparent PNG images from PDFs output by PrinceXML. I'm calling Ghostscript directly for the rasterization instead of using ImageMagick because ImageMagick delegates to Ghostscript for PDF rasterization and I should be able to control the rasterization better by calling GS directly. Thanks for your help. -Jon Wolfe

• sys.stdout not reassigning to sys.__stdout__

  - by Vince

  I'm pretty new to Python so I am still just learning the language. One of the things I came across was reassigning sys.stdout to change the default output of print. So I wrote this as a test: import sys sys.stdout = open('log.txt','a') print('hey') sys.stdout.close() sys.stdout = sys.__stdout__ print('hi') Now the string 'hi' is not written to the file but it does not show in the default output either. When I assign some other variable to sys.stdout in the beginning and change it back it works, but I'm just wondering why its not changing back the first time.

• Render a view as a string

  - by Dan Atkinson

  Hi all! I'm wanting to output two different views (one as a string that will be sent as an email), and the other the page displayed to a user. Is this possible in ASP.NET MVC beta? I've tried multiple examples: RenderPartial to String in ASP.NET MVC Beta If I use this example, I receive the "Cannot redirect after HTTP headers have been sent.". MVC Framework: Capturing the output of a view If I use this, I seem to be unable to do a redirectToAction, as it tries to render a view that may not exist. If I do return the view, it is completely messed up and doesn't look right at all. Does anyone have any ideas/solutions to these issues i have, or have any suggestions for better ones? Many thanks! Below is an example. What I'm trying to do is create the GetViewForEmail method: public ActionResult OrderResult(string ref) { //Get the order Order order = OrderService.GetOrder(ref); //The email helper would do the meat and veg by getting the view as a string //Pass the control name (OrderResultEmail) and the model (order) string emailView = GetViewForEmail("OrderResultEmail", order); //Email the order out EmailHelper(order, emailView); return View("OrderResult", order); } Accepted answer from Tim Scott (changed and formatted a little by me): public virtual string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) { filter.Dispose(); } //Now replace the response filter response.Filter = oldFilter; } } Example usage Assuming a call from the controller to get the order confirmation email, passing the Site.Master location. string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData);

• How to get XDebug working on Mac command line PHP

  - by Eugene M

  I recently installed Zend Server Community Edition on a Mac with Snow Leopard. I can't get XDebug to work ... it shows up in the output for phpinfo from a web browser, but when I var_dump() a variable, there is no special output, and when I run phpunit, code coverage reports aren't generated. Also when I type php -m at the command line, there is nothing for XDebug. I suspect that it's because the Mac is running the executable of PHP that was bundled with it instead of the executable of PHP that came with the Zend Server install. When I type /usr/local/zend/bin/php -m, XDebug does show up. I followed the instructions at http://akrabat.com/php/some-notes-on-zend-server-ce-for-mac-os-x/. Also I downloaded the xdebug.so from the Komodo web site. Zend Debugger and all other Zend extensions are disabled. So how can I get XDebug working correctly?

• perl escaping \n or \t

  - by Michael

  I need to escape \n so on output I really get newline or tab $ perl -p -e 's/e/a/ge' now I want each e to be substituted with \n $ perl -p -e 's/e/\n/ge' but even \n gives me an error. this was a simplified example. In real script(makefile) I have substitute := perl -p -e 's/@([^@]+)@/defined $$ENV{$$1} ? $$ENV{$$1} : $$1/ge' and in target I have such a nice command $(substitute) $< > $@ and if the input file for perl contains \n at output I will see it literally... I want to have real newline.

• ModelState.AddModelError encodes HTML

  - by NTulip

  Hi I am noticing a weird issue when using ModelState.AddModelError to validate input on my forms. The output from Html.ValidationMessage is not the true HTML value but it's encoded value and so the CSS style is not applied to the error message. Example: private string errorMessage = "<span class=\"negative\">{0}</span><br class=\"hid\" />"; ModelState.AddModelError("title", String.Format(errorMessage, "Tab title is required")); The output is shown as: <span class="field-validation-error">&lt;span class=&quot;negative&quot;&gt;URL is Required&lt;/span&gt;&lt;br class=&quot;hid&quot; /&gt;</span> This didn't use to be the case with their earlier beta's and I am not sure what approach to take here. Thanks Nick

• BDD for C# NUnit

  - by mjezzi

  I've been using a home brewed BDD Spec extension for writing BDD style tests in NUnit, and I wanted to see what everyone thought. Does it add value? Does is suck? If so why? Is there something better out there? Here's the source: https://github.com/mjezzi/NSpec There are two reasons I created this To make my tests easy to read. To produce a plain english output to review specs. Here's an example of how a test will look: -since zombies seem to be popular these days.. Given a Zombie, Peson, and IWeapon: namespace Project.Tests.PersonVsZombie { public class Zombie { } public interface IWeapon { void UseAgainst( Zombie zombie ); } public class Person { private IWeapon _weapon; public bool IsStillAlive { get; set; } public Person( IWeapon weapon ) { IsStillAlive = true; _weapon = weapon; } public void Attack( Zombie zombie ) { if( _weapon != null ) _weapon.UseAgainst( zombie ); else IsStillAlive = false; } } } And the NSpec styled tests: public class PersonAttacksZombieTests { [Test] public void When_a_person_with_a_weapon_attacks_a_zombie() { var zombie = new Zombie(); var weaponMock = new Mock<IWeapon>(); var person = new Person( weaponMock.Object ); person.Attack( zombie ); "It should use the weapon against the zombie".ProveBy( spec => weaponMock.Verify( x => x.UseAgainst( zombie ), spec ) ); "It should keep the person alive".ProveBy( spec => Assert.That( person.IsStillAlive, Is.True, spec ) ); } [Test] public void When_a_person_without_a_weapon_attacks_a_zombie() { var zombie = new Zombie(); var person = new Person( null ); person.Attack( zombie ); "It should cause the person to die".ProveBy( spec => Assert.That( person.IsStillAlive, Is.False, spec ) ); } } You'll get the Spec output in the output window: [PersonVsZombie] - PersonAttacksZombieTests When a person with a weapon attacks a zombie It should use the weapon against the zombie It should keep the person alive When a person without a weapon attacks a zombie It should cause the person to die 2 passed, 0 failed, 0 skipped, took 0.39 seconds (NUnit 2.5.5).

• Visual Studio add-in to quickly test a code snippet

  - by Matti Virkkunen

  One thing I really love about languages such as Python is that if you have a piece of code you'd like to try out, you can just open the interactive shell and do it in seconds. Is there a Visual Studio add-in that does the same for C#? Basically what I'm looking for is something that opens up a window or tab with a text editor (preferably with code completion, because VS does it so nicely) and a button that runs the code and displays the output. Extra points for convenience features such as displaying complex output in a user-friendly way (think Firebug's console.log), automatically referencing all the assemblies the current project references, etc. I tried googling for a while, but either I fail at coming up with good keywords, or no-one has made an add-in like this. If there really is none, I'm considering making one myself.

• Separate log files for each web application and shared libraries with log4j

  - by oo_olo_oo

  I have few web applications run on the Tomcat server. Each application contains its own log4j library copy inside its own war. This allows for separate, flexible logging configuration per application. I also have few shared libraries (kept in Tomcat's shared libraries directory). I would like to have shared library loggers output among with the application (which uses them) loggers output (for example: if application A logs to file a.log, and uses library b.jar, I would like b.jar to log also to the a.log file). The problem is, that the shared libraries are loaded by the shared classloader, which causes that they can't access loggers defined by the applications. Is there any solution for this issue?

• How to return a dynamic value from a Mocha mock in Ruby

  - by Vivek

  The gist of my problem is as follows:- I'm writing a Mocha mock in Ruby for the method represented as "post_to_embassy" below. It is not really our concern, for the purpose of describing the problem, what the actual method does. But I need the mock to return a dynamic value. The proc '&prc' below is executing rightly in place of the actual method. But the "with" method in Mocha only allows for boolean values to be returned. So the code below outputs nil. I need it to output the value being passed through orderInfoXml. Does anyone know of an alternate method I can use? require 'rubygems' require 'mocha' include Mocha::API class EmbassyInterface def post_to_embassy(xml) puts "This is from the original class:-" puts xml return xml end end orderInfoXml = "I am THE XML" mock = EmbassyInterface.new prc = Proc.new do |orderXml| puts "This is from the mocked proc:-" puts orderXml orderXml end mock.stubs(:post_to_embassy).with(&prc) mock_result = mock.post_to_embassy(orderInfoXml) p mock_result #p prc.call("asd") output:- This is from the mocked proc:- I am THE XML nil

• Row Number Transformation

  The Row Number Transformation calculates a row number for each row, and adds this as a new output column to the data flow. The column number is a sequential number, based on a seed value. Each row receives the next number in the sequence, based on the defined increment value. The final row number can be stored in a variable for later analysis, and can be used as part of a process to validate the integrity of the data movement. The Row Number transform has a variety of uses, such as generating surrogate keys, or as the basis for a data partitioning scheme when combined with the Conditional Split transformation. Properties Property Data Type Description Seed Int32 The first row number or seed value. Increment Int32 The value added to the previous row number to make the next row number. OutputVariable String The name of the variable into which the final row number is written post execution. (Optional). The three properties have been configured to support expressions, or they can set directly in the normal manner. Expressions on components are only visible on the hosting Data Flow task, not at the individual component level. Sometimes the data type of the property is incorrectly set when the properties are created, see the Troubleshooting section below for details on how to fix this. Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. For 2005/2008 Only - Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Row Number transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations, and this component requires a minimum of SQL Server 2005 Service Pack 1. Downloads The Row Number Transformation  is available for SQL Server 2005, SQL Server 2008 (includes R2) and SQL Server 2012. Please choose the version to match your SQL Server version, or you can install multiple versions and use them side by side if you have more than one version of SQL Server installed. Row Number Transformation for SQL Server 2005 Row Number Transformation for SQL Server 2008 Row Number Transformation for SQL Server 2012 Version History SQL Server 2012 Version 3.0.0.6 - SQL Server 2012 release. Includes upgrade support for both 2005 and 2008 packages to 2012. (5 Jun 2012) SQL Server 2008 Version 2.0.0.5 - SQL Server 2008 release. (15 Oct 2008) SQL Server 2005 Version 1.2.0.34 – Updated installer. (25 Jun 2008) Version 1.2.0.7 - SQL Server 2005 RTM Refresh. SP1 Compatibility Testing. Added the ability to reuse an existing column to hold the generated row number, as an alternative to the default of adding a new column to the output. (18 Jun 2006) Version 1.2.0.7 - SQL Server 2005 RTM Refresh. SP1 Compatibility Testing. Added the ability to reuse an existing column to hold the generated row number, as an alternative to the default of adding a new column to the output. (18 Jun 2006) Version 1.0.0.0 - Public Release for SQL Server 2005 IDW 15 June CTP (29 Aug 2005) Screenshot Code Sample The following code sample demonstrates using the Data Generator Source and Row Number Transformation programmatically in a very simple package. Package package = new Package(); package.Name = "Data Generator & Row Number"; // Add the Data Flow Task Executable taskExecutable = package.Executables.Add("STOCK:PipelineTask"); // Get the task host wrapper, and the Data Flow task TaskHost taskHost = taskExecutable as TaskHost; MainPipe dataFlowTask = (MainPipe)taskHost.InnerObject; // Add Data Generator Source IDTSComponentMetaData100 componentSource = dataFlowTask.ComponentMetaDataCollection.New(); componentSource.Name = "Data Generator"; componentSource.ComponentClassID = "Konesans.Dts.Pipeline.DataGenerator.DataGenerator, Konesans.Dts.Pipeline.DataGenerator, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b2ab4a111192992b"; CManagedComponentWrapper instanceSource = componentSource.Instantiate(); instanceSource.ProvideComponentProperties(); instanceSource.SetComponentProperty("RowCount", 10000); // Add Row Number Tx IDTSComponentMetaData100 componentRowNumber = dataFlowTask.ComponentMetaDataCollection.New(); componentRowNumber.Name = "FlatFileDestination"; componentRowNumber.ComponentClassID = "Konesans.Dts.Pipeline.RowNumberTransform.RowNumberTransform, Konesans.Dts.Pipeline.RowNumberTransform, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b2ab4a111192992b"; CManagedComponentWrapper instanceRowNumber = componentRowNumber.Instantiate(); instanceRowNumber.ProvideComponentProperties(); instanceRowNumber.SetComponentProperty("Increment", 10); // Connect the two components together IDTSPath100 path = dataFlowTask.PathCollection.New(); path.AttachPathAndPropagateNotifications(componentSource.OutputCollection[0], componentRowNumber.InputCollection[0]); #if DEBUG // Save package to disk, DEBUG only new Application().SaveToXml(String.Format(@"C:\Temp\{0}.dtsx", package.Name), package, null); #endif package.Execute(); foreach (DtsError error in package.Errors) { Console.WriteLine("ErrorCode : {0}", error.ErrorCode); Console.WriteLine(" SubComponent : {0}", error.SubComponent); Console.WriteLine(" Description : {0}", error.Description); } package.Dispose(); Troubleshooting Make sure you have downloaded the version that matches your version of SQL Server. We offer separate downloads for SQL Server 2005, SQL Server 2008 and SQL Server 2012. If you get an error when you try and use the component along the lines of The component could not be added to the Data Flow task. Please verify that this component is properly installed.  ... The data flow object "Konesans ..." is not installed correctly on this computer, this usually indicates that the internal cache of SSIS components needs to be updated. This is held by the SSIS service, so you need restart the the SQL Server Integration Services service. You can do this from the Services applet in Control Panel or Administrative Tools in Windows. You can also restart the computer if you prefer. You may also need to restart any current instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Once installation is complete you need to manually add the task to the toolbox before you will see it and to be able add it to packages - How do I install a task or transform component? Please also make sure you have installed a minimum of SP1 for SQL 2005. The IDtsPipelineEnvironmentService was added in SQL Server 2005 Service Pack 1 (SP1) (See  http://support.microsoft.com/kb/916940). If you get an error Could not load type 'Microsoft.SqlServer.Dts.Design.IDtsPipelineEnvironmentService' from assembly 'Microsoft.SqlServer.Dts.Design, Version=9.0.242.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'. when trying to open the user interface, it implies that your development machine has not had SP1 applied. Very occasionally we get a problem to do with the properties not being created with the correct data type. Since there is no way to programmatically to define the data type of a pipeline component property, it can only infer it. Whilst we set an integer value as we create the property, sometimes SSIS decides to define it is a decimal. This is often highlighted when you use a property expression against the property and get an error similar to Cannot convert System.Int32 to System.Decimal. Unfortunately this is beyond our control and there appears to be no pattern as to when this happens. If you do have more information we would be happy to hear it. To fix this issue you can manually edit the package file. In Visual Studio right click the package file from the Solution Explorer and select View Code, which will open the package as raw XML. You can now search for the properties by name or the component name. You can then change the incorrect property data types highlighted below from Decimal to Int32. <component id="37" name="Row Number Transformation" componentClassID="{BF01D463-7089-41EE-8F05-0A6DC17CE633}" … >     <properties>         <property id="38" name="UserComponentTypeName" …>         <property id="41" name="Seed" dataType="System.Int32" ...>10</property>         <property id="42" name="Increment" dataType="System.Decimal" ...>10</property>         ... If you are still having issues then contact us, but please provide as much detail as possible about error, as well as which version of the the task you are using and details of the SSIS tools installed.

• Force maximum width and height for PHPThumb images

  - by Peter

  PHPThumb provides two great variables setting the output maximum width and height BUT "This is always overridden by ?w=_ GETstring parameter" $PHPTHUMB_CONFIG['output_maxwidth'] = 720; $PHPTHUMB_CONFIG['output_maxheight'] = 720; You can also set defaults, and for landscape/portrait: $PHPTHUMB_DEFAULTS['w'] = 720; $PHPTHUMB_DEFAULTS['h'] = 720; $PHPTHUMB_DEFAULTS['hp'] = 720; $PHPTHUMB_DEFAULTS['wl'] = 720; You can set the getsringoverride to enforce the default width/height but then you can't have width/height smaller than the default. $PHPTHUMB_DEFAULTS_GETSTRINGOVERRIDE = false; There doesn't seem to be a way to allow the get paramaters to be used but if entering a value higher than the output_maxwidth/height it outputs that size, not the maximum. How can the output be explicitly restricted to a maximum size, hence protecting the source images?
