  • [PHP-GD] Background transperancy in imagerotate()

    - by KPL
    Hello people, Since last 2 days, I was trying to add transperancy to the background after rotating an image using imagerotate() PHP-GD function. But, to my great disappointment, it's not working at all. It's just giving out a black background behind it. Here's my code - $patchImageS = 'image.png'; // the image to be patched over the final bg $patchImage = imagecreatefrompng($patchImageS); // resource of image to be patched $patchImage = imagerotate($patchImage, 23, 0, 0); imagepng($patchImage,'tt.png'); I tried to change the parameters being passed in function to imagerotate($patchImage, 23, 5, 0); imagerotate($patchImage, 23, 0, 5); Any help would be highly appreciated.

  • moving between states I get an error in Flex.

    - by Adam
    ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. so i have a function that runs in state1 and has a while(myCanvas.rawChildren.numChildren > 0){ myCanvas.rawChildren.removeChildAt(0); } //this code is definitely the problem.... I can move to state2, but when I move back to state1 i get the error. why? the function that has the while loop only runs when something is searched in state1, so why is it running when coming back from state2?

  • Can't call method in model table class using Doctrine with Zend Framework

    - by Jeremy Hicks
    I'm using Doctrine with Zend Framework. For my model, I'm using a base class, the regular class (which extends the base class), and a table class. In my table class, I've created a method which does a query for records with a specific value for one of the fields in my model. When I try and call this method from my controller, I get an error message saying, "Message: Unknown method Doctrine_Table::getCreditPurchases". Is there something else I need to do to call functions in my table class? Here is my code: class Model_CreditTable extends Doctrine_Table { /** * Returns an instance of this class. * * @return object Model_CreditTable */ public static function getInstance() { return Doctrine_Core::getTable('Model_Credit'); } public function getCreditPurchases($id) { $q = $this->createQuery('c') ->where('c.buyer_id = ?', $id); return $q->fetchArray(); } } // And then in my controller method I have... $this->view->credits = Doctrine_Core::getTable('Model_Credit')->getCreditPurchases($ns->id);

  • Propel: How the "Affected Rows" Returned from doUpdate is defined

    - by Ngu Soon Hui
    In propel there is this doUpdate function, that will return the numbers of affected rows by this query. The question is, if there is no need to update the row ( because the set value is already the same as the field value), will those rows counted as the affected row? Take for example, I have the following table: ID | Name | Books 1 | S1oon | Me 2 | S1oon | Me Let's assume that I write a ORM function of the equivalent of the following query: update `new table` set Books='Me' where Name='S1oon'; What will the doUpdate result return? Will it return 0 ( because all the Books column are already Me, hence there is no need to update), or will it be 2 ( because there are 2 rows that fulfill the where condition) ?

  • Invalid Cross-Thread Operations from BackgroundWorker2_RunWorkerCompleted in C#

    - by Jim Fell
    Hello. I'm getting an error that does not make sense. Cross-thread operation not valid: Control 'buttonOpenFile' accessed from a thread other than the thread it was created on. In my application, the UI thread fires off backgroundWorker1, which when almost complete fires off backgroundWorker2 and waits for it to complete. backgroundWorker1 waits for backgroundWorker2 to complete, before it completes. AutoResetEvent variables are used to flag when each of the workers complete. In backgroundWorker2_RunWorkerComplete a function is called that resets the form controls. It is in this ResetFormControls() function where the exception is thrown. I thought it was safe to modify form controls in the RunWorkerCompleted function. Both background workers are instantiated from the UI thread. Here is a greatly summarized version of what I am doing: AutoResetEvent evtProgrammingComplete_c = new AutoResetEvent(false); AutoResetEvent evtResetComplete_c = new AutoResetEvent(false); private void ResetFormControls() { toolStripProgressBar1.Enabled = false; toolStripProgressBar1.RightToLeftLayout = false; toolStripProgressBar1.Value = 0; buttonInit.Enabled = true; buttonOpenFile.Enabled = true; // Error occurs here. buttonProgram.Enabled = true; buttonAbort.Enabled = false; buttonReset.Enabled = true; checkBoxPeripheryModule.Enabled = true; checkBoxVerbose.Enabled = true; comboBoxComPort.Enabled = true; groupBoxToolSettings.Enabled = true; groupBoxNodeSettings.Enabled = true; } private void buttonProgram_Click(object sender, EventArgs e) { while (backgroundWorkerProgram.IsBusy) backgroundWorkerProgram.CancelAsync(); backgroundWorkerProgram.RunWorkerAsync(); } private void backgroundWorkerProgram_DoWork(object sender, DoWorkEventArgs e) { // Does a bunch of stuff... if (tProgramStat_c == eProgramStat_t.DONE) { tProgramStat_c = eProgramStat_t.RESETTING; while (backgroundWorkerReset.IsBusy) backgroundWorkerReset.CancelAsync(); backgroundWorkerReset.RunWorkerAsync(); evtResetComplete_c.WaitOne(LONG_ACK_WAIT * 2); if (tResetStat_c == eResetStat_t.COMPLETED) tProgramStat_c = eProgramStat_t.DONE; } } private void backgroundWorkerProgram_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { // Updates form to report complete. No problems here. evtProgrammingComplete_c.Set(); backgroundWorkerProgram.Dispose(); } private void backgroundWorkerReset_DoWork(object sender, DoWorkEventArgs e) { // Does a bunch of stuff... if (tResetStat_c == eResetStat_t.COMPLETED) if (tProgramStat_c == eProgramStat_t.RESETTING) evtProgrammingComplete_c.WaitOne(); } private void backgroundWorkerReset_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { CloseAllComms(); ResetFormControls(); evtResetComplete_c.Set(); backgroundWorkerReset.Dispose(); } Any thoughts or suggestions you may have would be appreciated. I am using Microsoft Visual C# 2008 Express Edition. Thanks.

  • Loading and removing images with DOM, Javascript

    - by jesse
    I'm new to DOM and I'm having trouble removing multiple images that I loaded this loads 7 images (1.jpg, 2.jpg, etc..) function loadImages() { for (var i = 1; i < 8; i++ ) { var img = document.createElement("img"); img.src = "images/"+i+".jpg"; var idName = "img"+i+""; document.getElementById(idName).appendChild(img); } } this should remove all of them, but doesn't.. I think it breaks at the removeChild line. function removeImages() { for (var i = 1; i < 8; i++ ) { var idName = "img"+i+""; var d = document.getElementById(idName); d.removeChild(document.getElementById(img)); } } I think I'm doing something fundamentally wrong, because I don't fully understand how this works...

  • Haskell - mapping the odd placed values and the even placed values differently

    - by Abstract
    Hey guys, is there an easy way. To take a list of numbers, say 123456. Then multiply the odd placed by three and the even placed by 1. i.e. (1 * 3) + (2 * 1) + (3 * 3) + (4*1) + (5*3) + (6*1) i was thinking the map function somewhere along the lines. But i don't know how to map *3 to just the odd placed values. Oh and if you could give me the version not in prelude that would be great like the actual function or functions, as if its being imported from an external haskell file Thanks for the help

  • Passing variable string to create arrays (Android)

    - by dweebsonduty
    Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }

  • Check if window has focus

    - by user2536244
    I need to check if the user has windows on focus, I'm currently doing this: var isonfocus=true; window.onblur = function(){ isonfocus=false; } window.onfocus = function(){ isonfocus=true; } And whenever I need to check if the user has the windows on focus I just do if(isonfocus==true). Problem: if the user loses focus before the page loads, even if I do if(isonfocus==true) it will return true, even though the window is not on focus, and defining the var to false var isonfocus=false; will do the reverse. Can someone help me? Thanks.

  • jquery animating different img widths

    - by romeozor
    Hi there, I've been searching for an answer for a long time with no avail, so it's time to ask. I'm trying to use .animate() to change the size of an image once clicked. The first state of the image would be a thumbnail size, which would animate to the image's original size, then to a thumbnail again. The problem is, not all the images have the same "original" size so I need a way to tell one generic function to switch to the current image's original size. This is my current code which loads on $(window).load: $('img[class=resize]').click(function (){ if ($(this).width() != 150) { $(this).animate({width: '150px'}, 400); } else { $(this).animate({width: ''}, 400); } }); Now this obviously doesn't work the way I want it, because .animate() thinks when I say width: '' I want to make the width = 0. Any suggestions how I should go about this?

  • SVG Using Adobe in IE doesn't work when loading page, but saving the page and then loading it works.

    - by Nick
    So I'm trying to get a SVG document to load in IE. I can see it fine, but all calls to .getSVGDocument() fail, the svg onload="onload()" function never gets called and the right-click Adobe SVG Viewer context menu doesn't show up when right-clicking on the svg. It seems as though I'm managing to crash the adobe SVG viewer or something before it is able to call the onload function but after it has drawn the SVG document. As a test I saved the html page to my hard drive and loaded it up and walla - it works! Right-click, onload, and .getSVGDocument() all work. Very curious. For some reason getting the page from the server makes the adobe plugin crap out but loading up static HTML is fine. Any thoughts?

  • Use deployJava.js to check for/automatically install latest JRE version for web applet

    - by Pryo
    I'd like to use the deployJava.js tool to have Java automatically detect the currently installed JRE and install an updated version if necessary. My initial impression when reading about deployJava.js was that it would do this out of the box when you simply set a version number as a function parameter for the "runApplet" function. But this has never seemed to work. Is it even possible to do this, and if so, how? Here is my current code for launching my applet: <script type="text/javascript" src="https://www.java.com/js/deployJava.js"></script> <script type="text/javascript"> var attributes = {id:"applet", name:"TheApplet", code:"TheApplet"}; var parameters = {jnlp_href: "http://localhost/TheApplet.jnlp"}; deployJava.runApplet(attributes, parameters, "1.6.0_31"); </script> Thanks

  • get_called_class hack not working with eval-code.

    - by Ekampp
    Hi there. I am using a ge_called_class hack for allowing late static binding in php version 5.2 (found here). I have the following in my code: # db_record.php $ac = "ForumThread"; $objects = $ac::find("all"); This will not work in php 5.2 for some reason, so I have done this: # db_record.php $ac = "ForumThread"; eval("\$objects = {$ac}::find('all');"); This on the other hand will not work with the get_called_class function. I get an error that the file function can't read the evaled section of code. So how do I solve this problem? Best regards.
