• Why pseudo-elements :before and :after appear in front of my DIV element and not behind?

  - by Dim13i

  I have a DIV element with this given class: .slideshow { background: white; width: 700px; height: 300px; padding:10px; margin: 0 auto; position: relative; box-shadow: 0px 0px 5px grey, 0px 10px 20px rgba(0,0,0,.1) inset; } I define those two pseudo-elements (:before and :after): .slideshow:before, .slideshow:after { content: " "; background: green; width: 50%; height: 50%; position: absolute; z-index: -10; } My problem is that those two pseudo-elements appear in front of my DIV and not behind. Is there any specific reason for this behaviour? Here is an example: EXAMPLE The Javascript part is a bit messy but i'm still working on it. Also I've noticed that if I delete all the JS part I don't have anymore this problem, but I don't think there is anything in the code that should modify the slideshow DIV SOLVED: The problem is in the javascript part where I have: $('.slideshow').css('-webkit-transform', 'rotate(0deg)'); Removing this line solved the problem. I guess that pseudo-elements :before and :after are not compatible with the property transform.

• Why do I get errors when using unsigned integers in an expression with C++?

  - by neuviemeporte

  Given the following piece of (pseudo-C++) code: float x=100, a=0.1; unsigned int height = 63, width = 63; unsigned int hw=31; for (int row=0; row < height; ++row) { for (int col=0; col < width; ++col) { float foo = x + col - hw + a * (col - hw); cout << foo << " "; } cout << endl; } The values of foo are screwed up for half of the array, in places where (col - hw) is negative. I figured because col is int and comes first, that this part of the expression is converted to int and becomes negative. Unfortunately, apparently it doesn't, I get an overflow of an unsigned value and I've no idea why. How should I resolve this problem? Use casts for the whole or part of the expression? What type of casts (C-style or static_cast<...)? Is there any overhead to using casts (I need this to work fast!)? EDIT: I changed all my unsigned ints to regular ones, but I'm still wondering why I got that overflow in this situation.

• Creating Thumbnails with CFImage Aborting Because of Server Load?

  - by nephilite

  I am uploading in image via a form and I want to, in addition to saving the image, save a variety of thumbnails in both png and jpg format. To do this I am using the code below. The initial image uploads fine but then, after spinning for a moment I get an error of: "Request aborted due to heavy system load." (from my host crystaltech), and none of the thumbnails have made it through. I've tried it with even just one resize (and no converts) and it still fails. What am I doing wrong? This issue is somewhat urgent....Thanks! ` <cffile action="upload" destination="#Application.filePath#Icons\#app#Icon.png" filefield="Icon" nameconflict="overwrite"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="50%" height="50%" destination="#Application.filePath#Icons\#app#Icon_Half.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="resize" width="25%" height="25%" destination="#Application.filePath#Icons\#app#Icon_Quarter.png" overwrite="yes"> <cfimage source="#Application.filePath#Icons\#app#Icon.png" action="convert" destination="#Application.filePath#Icons\#app#Icon.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Half.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Half.jpg"> <cfimage source="#Application.filePath#Icons\#app#Icon_Quarter.png" action="convert" destination="#Application.filePath#Icons\#app#Icon_Quarter.jpg"> `

• Is there an equivalent for ActiveRecord#find_by equivalent for C#?

  - by Benjamin Manns

  I'm originally a C# developer (as a hobby), but as of late I have been digging into Ruby on Rails and I am really enjoying it. Right now I am building an application in C# and I was wondering if there is any collection implementation for C# that could match (or "semi-match") the find_by method of ActiveRecord. What I am essentially looking for is a list that would hold Rectangles: class Rectangle { public int Width { get; set; } public int Height { get; set; } public String Name { get; set; } } Where I could query this list and find all entries with Height = 10, Width = 20, or name = "Block". This was done with ActiveRecord by doing a call similar to Rectangle.find_by_name('Block'). The only way I can think of doing this in C# is to create my own list implementation and iterate through each item manually checking each item against the criteria. I fear I would be reinventing the wheel (and one of poorer quality). Any input or suggestions is much appreciated.

• Fast, Unicode-capable, cross-platform programmer's text editor that shows invisibles like ZWSP?

  - by Roger_S

  Our publishing workflow includes Windows and Linux machines (there are some Macs too, but not in the critical-path workflow). Many texts include both English and Khmer and are marked-up in XML. XML Copy Editor is the best cross-platform open-source XML editor I've discovered. It utilizes the Scintilla editing component, which is generally good with Unicode but which does not enable non-printing or invisible characters like U+200B (zero-width space) and U+200C (zero-width non-joiner) to be displayed. Khmer does not separate words with a space character as Western languages do, so ZWSP is used in electronic texts to enable applications to break lines easily. Ideally I'd edit the markup and the content in a single editor, but XML awareness is less important at times than being able to display invisibles. (OpenOffice.org Writer and Microsoft Word are the only two apps I know that will display ZWSP. They are not suitable for the markup and text manipulations that need to be done to prepare manuscripts for publication, unfortunately, although I guess they're fine for authoring.) I tried out a promising editor last week, but a search-and-replace regex operation that took under a second in TextPad 4.7.3 lasted over twenty seconds. So I want to mention that speed and the ability to handle large (up to 150mb) files is also a concern. Is there a good, fast, free or not too expensive text editor, with versions on Windows and Linux and maybe mac too, Unicode-aware and capable of displaying invisibles like ZWSP? That has syntax highlighting, can handle large files and is customizable enough that I won't tear my hair out in frustration? Thanks, Roger_S

• Opencv video frame not showing Sobel output

  This is a continuation question from Opencv video frame giving me an error I think I closed it off, Im new to Stackoverflow. I have code below that Im trying to see its Sobel edge image. However the program runs but the output is just a grey screen where if I mouseover the cursor disappears. Does anyone see the error? or is it a misunderstanding about the data structures Im using IplImage *frame, *frame_copy = 0; // capture frames from video CvCapture *capture = cvCaptureFromFile( "lightinbox1.avi"); //Allows Access to video propertys cvQueryFrame(capture); //Get the number of frames int nframe=(int) cvGetCaptureProperty(capture,CV_CAP_PROP_FRAME_COUNT); //Name window cvNamedWindow( "video:", 1 ); //start loop for(int i=0;i<nframe;i++){ //prepare capture frame extraction cvGrabFrame(capture); cout<<"We are on frame "<<i<<"\n"; //Get this frame frame = cvRetrieveFrame( capture ); con2txt(frame); frame_copy = cvCreateImage(cvSize(frame->width,frame->height),IPL_DEPTH_8U,frame->nChannels ); //show and destroy frame cvCvtColor( frame,frame,CV_RGB2GRAY); //Create Sobel output frame_copy1 = cvCreateImage(cvSize(frame->width,frame->height),IPL_DEPTH_16S,1 ); cvSobel(frame_copy,frame_copy1,2,2,3); cvShowImage("video:",frame_copy1); cvWaitKey(33);} cvReleaseCapture(&capture);

• YouTube API, jQuery attr won't swap element attributes (I think) in IE, but works in FF

  - by Anthony

  JavaScript (jQuery) function display_youtube(new_url) { $('#movie_url').removeAttr('value'); $('#embed_url').removeAttr('src'); $(document).ready(function() { $('#movie_url').attr('value', new_url); $('#embed_url').attr('src', new_url); $('#shade').css('display', 'block'); $('#youtube_player').css('display', 'block'); $('#exit_youtube').css('display', 'block'); }); } HTML <object width="720" height="480"> <param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" /> <param name="allowFullScreen" value="true" /> <param name="allowscriptaccess" value="always" /> <embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" /> </object> Hyperlink <a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a> What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?

• Rendering a CGPDFPage into a UIImage

  - by James Antrobus

  I'm trying to render a CGPDFPage (selected from a CGPDFDocument) into a UIImage to display on a view. I have the following code in MonoTouch which gets me part way there. RectangleF PDFRectangle = new RectangleF(0, 0, UIScreen.MainScreen.Bounds.Width, UIScreen.MainScreen.Bounds.Height); public override void ViewDidLoad () { UIGraphics.BeginImageContext(new SizeF(PDFRectangle.Width, PDFRectangle.Height)); CGContext context = UIGraphics.GetCurrentContext(); context.SaveState(); CGPDFDocument pdfDoc = CGPDFDocument.FromFile("test.pdf"); CGPDFPage pdfPage = pdfDoc.GetPage(1); context.DrawPDFPage(pdfPage); UIImage testImage = UIGraphics.GetImageFromCurrentImageContext(); pdfDoc.Dispose(); context.RestoreState(); UIImageView imageView = new UIImageView(testImage); UIGraphics.EndImageContext(); View.AddSubview(imageView); } A section of the CGPDFPage is displayed but rotated back-to-front and upside down. My question is, how do I select the full pdf page and flip it round to display correctly. I have seen a few examples using ScaleCTM and TranslateCTM but couldn't seem to get them working. Any examples in ObjectiveC are fine, I'll take all the help I can get :) Thanks

• Dynamic editor upload into web page. Need advice

  - by Andrew Florko

  Hello everybody, I am writing intranet site for tracking employees science activities in organization. There lots of editable information on each personal page (science degree, publications & so on) so I upload editor per request (user clicks "edit" and modal dialog with html editor: set of textboxes/comboboxes/autocomplete features & validation logic appears). Editor is html layout that is wrapped with jquery dialog plugin + some logic, written as javascript functions that should be invoked from the callee page (onsubmit, validate, afterLoad editor events). There are also attributes (editor preferrable with and height) that are passed to callee page also. Currently I send these functions & attribute as ... function onsubmit() { }; function validate() { } var width = 640; var height = 800 ... code that is embedded into the request page. Function calls and editor markup wrap with jquery plugin completed in the callee page. It works, but I have some try { call editor event handler } catch { } stuff in callee page (because not every editor provides these functions) and some attributes (editor width & height for instance) that are loaded as variables declared in javascript. Please, suggest, is there a better approach to build & use custom editors for my situation. Thank you in advance!

• jQuery Manual Resizable DIV

  - by JC

  Hi, I'm trying to create a resizable div without using jQuery's interface library. var myY = 0; var mouseDown = false; var originalHeight = 0; function resize(e){ if(mouseDown == true){ $("#cooldiv").height(originalHeight+e.pageY-myY); } } $(document).ready(function(){ $().mouseup(function(e){ myY = 0; mouseDown = false; originalHeight = 0; $().unbind("mousemove", resize); }); $("#resizeBar").mousedown(function(e){ myY = e.pageY; originalHeight = $("#cooldiv").height(); mouseDown = true; $().bind("mousemove", resize); }); }); ... <div id="cooldiv" style="width: 500px; height: 300px; background-color: #cccccc; position: relative;"> <div id="resizeBar" style="height: 10px; width: 500px; background-color: #aaaaaa; position: absolute; bottom: 0;"></div> </div> The first resize works fine(i.e. mousedown, mousemove then mouseup), but on subsequent (mousedown+mousemove)s, the browser attempts to drag the whole resizeBar div instead of properly resizing its parent container. On mouseup, the div then starts resizing "cooldiv" on mousemove without any mousedown required, until a further click of the mouse. These problems don't show up in Internet Explorer.

• Center big image in smaller div

  - by larin555

  I'm trying to align images in the center of a slider div. I'm adjusting FlexSlider css by the way. Here's my CSS code : .flexslider {margin: 0; padding: 0; width: 600px; height:480px; overflow:hidden;margin-left:auto;margin-right:auto;} .flexslider .slides > li {display: none; -webkit-backface-visibility: hidden;} /* Hide the slides before the JS is loaded. Avoids image jumping */ .flexslider .slides img {width:auto;height:100%; display: inline-block; text-align:center;} Everything is working like I want, except that I want wider image to be centered in the div. Right now it is left-aligned. I cannot use background-image by the way. Any ideas? I also tried applying to the .flexslider .slides img : margin-left:-50%...not working margin-left:auto and margin-right:auto...not working left:50% and right:50%...not working either

• CSS: 100% of container height without modifying the container

  - by Rena

  Yeah, this ugly question again. I'm writing some HTML that gets inserted into a page. I have no control over the rest of the page. The structure is something like: <table <tr <td rowspan="2"left column</td <td height="1"top row above content</td </tr <tr<td height="220"my content here</td</tr </table I can write whatever I want into that table cell (including style tags to pack in my CSS), but I can't touch anything outside of it, which means I can't set the height of any parent element (including html and body), add a doctype (it has none), etc - that already kills just about every solution I can find (all seem to be "add a doctype" and/or "give the parent container a fixed height"). What I want to do is simply have a <div fill the entire cell. Width is no problem but unsurprisingly height is being a massive pain. Writing "height: 100%" doesn't do anything unless the container has a fixed height (the height="220" attribute apparently doesn't count) or the div uses absolute positioning - and then it seems to want to use 100% of the window's height (and width even) instead of the cell's. The root of the problem is the left column varies in height, as does the content, and when the left column cell is larger than the content, it won't expand to fill the cell it's in. If I set a fixed height for the content, it'll be much larger than necessary most of the time, and if I don't, it doesn't take up all of the cell and leaves an ugly gap at the bottom.

• HTML5 Video Element on iPad doesn't fire onclick?

  - by bhups

  I am using the video element in my HTML as following:<div id="container" style="background:black; overflow:hidden;width:320px;height:240px" <video style="background:black;display:block" id="vdo" height="240px" width="320px" src="http://mydomain/vid.mp4"</video</div And in javascript I am doing this:var video=document.getElementById('vdo'); var container=document.getElementById('container'); video.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); container.addEventListener('click', function(e) { e.preventDefault(); console.log("clicked"); }, false); On desktop safari/chrome everything is working fine. I can see two "clicked" in the console. But on ipad there is nothing. First I tried with iOS versin 3.2, then I updated it to the latest one 4.2.1 without any success.I found a similar question HTML5 Video Element on iPad doesn't fire onclick or touchstart events? where it suggests not to use controls in video tag and I am not using it.

• Why is this unordered list formatting differently in IE7?

  I'm better about getting things to look good in IE8, FF, and Safari, but IE7 still throws curve balls at me... Please check out this page and scroll down below the nav bar: http://rattletree.com/instruments.php It should become obvious when viewing in FF vs IE7. For some reason the formatting of the list is pushing the list items down on the page... any tips? <ul class="instrument"> <li class="imagebox"><img src="/images/stuff.jpg" width="247" height="228" alt="Matepe" /></li> <li class="textbox"><h3>Matepe</h3><p>This text should be to the right of the image but drops below the image in IE7</p></li> </ul> css: ul.instrument { text-align:left; display:inline-block; } ul.instrument li { list-style-type: none; display:inline-block; } li.imagebox { display:inline; margin:20px 0; padding:0px; vertical-align:top; } li.imagebox img{ border: solid black 1px; } li.textbox { display:inline; } li.textbox p{ margin:10px; width:340px; display:inline-block; }

• How to make DataGrid Row really fully selectable (clicking on non-cell area)

  - by Samuel

  The question might be a little misleading. Here is a screenshot of a DataGrid that has some dummy values (code provided below) Is there a way to make the white area not covered by a cell clickable? My intention: I want to have full row selection. This can be achieved by SelectionUnit="FullRow" which is fine but how can I make the white area implicitly select the entire row without expanding available cells in width and avoiding code behind Here is the repro code: Xaml: <Window x:Class="DGVRowSelectTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" DataContext="{Binding RelativeSource={RelativeSource Self}}"> <DataGrid ItemsSource="{Binding Names}" SelectionMode="Single" SelectionUnit="FullRow" > </DataGrid> </Window> Dummy Code behind of it (just sets the two entries up) using System.Collections.Generic; using System.Windows; namespace DGVRowSelectTest { public partial class MainWindow : Window { private IList<KeyValuePair<string, string>> _names = new List<KeyValuePair<string, string>>{new KeyValuePair<string, string>("A1", "A2"),new KeyValuePair<string, string>("B1","B2")}; public IList<KeyValuePair<string, string>> Names{get { return _names; }set { _names = value; }} public MainWindow() { InitializeComponent(); } } }

• Wrong values reported by pyPDF for various box regions

  - by romor

  Using pyPdf, for most files I get matched results concerning various box's dimensions compared to what Acrobat reports. However for some files I get different values reported by pyPdf and Acrobat, like: pyPdf: artBox: 595.3 x 841.9 bleedBox: 595.3 x 841.9 cropBox: 595.3 x 841.9 trimBox: 517.3 x 754 Acrobat: artBox: 439.35 x 666.13 pt bleedBox: 439.35 x 666.13 pt cropBox: 439.35 x 666.13 pt trimBox: 439.35 x 666.13 pt I thought it's units issue, but then ratio between widths and heights doesn't match also, not mentioning trimBox mismatch Correct results are those reported by Acrobat of course. Does someone know why is this and is there a way I get correct dimensions by using pyPdf? Thanks couple of minutes later... After reading this question: Are PDF box coordinates relative or absolute? I figured I didn't considered uper left corner to be different then 0 (zero). It turned out that box starts at 77.95 x 87.87, so if we reduce reported values of trimBox by this values correct result is obtained. artBox: 0 x 0 bleedBox: 0 x 0 cropBox: 0 x 0 trimBox: 77.95 x 87.87 Other boxes seem with misleading values or I misinterpret them. Snippet: from pyPdf import PdfFileReader pdfread = PdfFileReader(file('my.pdf', 'rb')) page = 1 width = pdfread.getPage(page).trimBox[2]-pdfread.getPage(page).trimBox[0] height = pdfread.getPage(page).trimBox[3] - pdfread.getPage(page).trimBox[1] print width, height

• Get Highest Res Favicon

  - by Jeremy

  I'm making a website that needs to dynamically obtain the favicon of sites upon request. I've found a few api's that can accomplish this fairly well, and so far I'm liking http://www.fvicon.com/. The final image for my website will be 64x64px, and some websites such as Google and Wordpress have nice images of this size that are easily retrieved via this api. Though, of course, most websites only have a 16x16 favicon image and scaling that image to 64x64 has very bad quality loss. Examples: (high res) http://a.fvicon.com/wordpress.com?format=png&width=64&height=64 (low res) http://a.fvicon.com/yahoo.com?format=png&width=64&height=64 Keeping this in mind, I'm planning on somehow determining whether a high-res image is available and, if so, the website will use this image. If not, I want to use a pre-made 64x64 icon with the smaller icon layered over it. What I'm having trouble with is determining if there is a high res favicon available or not. Also, I'm curious if there's a better approach to this situation. I'd rather not use smaller images (64x64 works out really well for this project). The lowest res I'm willing to drop to is 48x48 but even then there will be a significant quality loss for scaling up 16x16 favicons. Any ideas? If you need any more information I will gladly provide it. Thank you!
