  • Jquery hide show list

    - by faxtion
    Having few issues with a jquery hide show item. Got a list of images, want to show the first one but hide the rest and when the user clicks next the current one is hidden and then the next list item is shown. Been banging head against wall for a while, and there is probably a very easy solution but for some reason I am unable to see it. Would be grateful of any advice. $(function() { $('#feat>li:gt(0)').hide(); var $links = $('#feat>li'); var $item = $('#feat>li'); $links.click(function() { var $par = $(this); $par.slideUp(700, function() { var index = $links.index( $par.get(0) ) $item.eq( index ).slideDown(700); }); }); }); <div id="feature"> <ul id="feat"> <li><img src="images/sample.png" /><a href="#">Next</a></li> <li><img src="images/sample2.jpg" /><a href="#">Next</a></li> <li><img src="images/sample.png" /><a href="#">Next</a></li> </ul> </div>

  • Stretch Background Image Resizes With Browser Windows

    - by user241673
    I am trying to replicate the image resizing found at http://devkick.com/lab/fsgallery/ but with the code I have below, it is not working properly. When resizing the browser window to have small width and big height, white space shows up at the bottom of the page. feel free to see it & edit at http://jsbin.com/ifolu3 The CSS: html, body {width:100%; height:100%; overflow:hidden;} div.bg {position:absolute; width:200%; height:200%; top:-50%; left:-50%;} img.bg {min-height:50%; min-width:50%; margin:0 auto; display:block;} The JS/jQuery: $(window).resize(function(){ var ratio = Math.max($(window).width()/$('img.bg').width(),$(window).height()/$('img.bg').height()); if ($(window).width() $(window).height()) { $('img.bg').css({width:image.width()*ratio,height:'auto'}); } else { $('img.bg').css({width:'auto',height:image.height()*ratio}); } }); The HTML - (sorry for the formatting, had trouble getting "<" to show) [body] [div class="bg"] [img class="bg" src="bg.jpg" /] [/div] [/body]

  • FileReference.load() does not as excepted

    - by Yang Bo
    I used Flash player 10, and Flex SDK 3.4. The code as followings: // Following comes callbacks function imageLoadOpenCallback(evt:Event):void { trace("in--open"); } function imageLoadCompleteCallback(evt:Event):void { trace("in--load"); var fr:FileReference = evt.target as FileReference; trace(fr.data); } function imageLoadErrorCallback(evt:IOErrorEvent):void { trace("in--ioerror"); } function imageSelectCancelCallback(evt:Event):void { trace("in cancel"); } function imageSelectCallback(evt:Event):void { trace("in -- select"); for (var i:int=0; i<frl.fileList.length; i++) { frl.fileList[i].addEventListener(Event.OPEN, imageLoadOpenCallback); frl.fileList[i].addEventListener(Event.COMPLETE, imageLoadCompleteCallback); frl.fileList[i].addEventListener(IOErrorEvent.IO_ERROR, imageLoadErrorCallback); frl.fileList[i].load(); trace(frl.fileList[i]); trace(frl.fileList[i].creationDate); trace(frl.fileList[i].creator); trace(frl.fileList[i].data); trace(frl.fileList[i].name); } } // Following comes UI handlers function onAddPictures():void { var imageFilter:FileFilter = new FileFilter("Images", "*.jpg;*.png"); frl.addEventListener(Event.SELECT, imageSelectCallback); frl.addEventListener(Event.CANCEL, imageSelectCancelCallback); frl.browse([imageFilter]); } Only the imageSelectCancelCallback handler get called when I select some files in the dialog. But no load/open/io_error handler get called at all. I have Google some code example, in which it used FileReference instead of FileReferenceList. I don't know the reason, could you please help me?

  • SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

    - by Kami
    I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

  • jQuery How do you get an image to fade in on load?

    - by Cool Hand Luke UK
    All I want to do is fade my logo in on the page loading. I am new today to jQuery and I can't managed to fadeIn on load please help.

  • possible to have a 'publish to facebook' button on my site?

  • QT- QImage and multi-threading problem.

    - by umanga
    Greetings all, Please refer to image at : http://i48.tinypic.com/316qb78.jpg We are developing an application to extract cell edges from MRC images from electron microscope. MRC file format stores volumetric pixel data (http://en.wikipedia.org/wiki/Voxel) and we simply use 3D char array(char***) to load and store data (gray scale values) from a MRC file. As shown in the image,there are 3 viewers to display XY,YZ and ZX planes respectively. Scrollbars on the top of the viewers use to change the image slice along an axis. Here is the steps we do when user changes the scrollbar position. 1) get the new scrollbar value.(this is the selected slice) 2) for the relavant plane (YZ,XY or ZX), generate (char* slice;) array for the selected slice by reading 3D char array (char***) 3) Create a new QImage* (Format_RGB888) and set pixel values by reading 'slice' (using img-setPixel(x,y,c);) 4) This new QImage* is painted in the paintEvent() method. We are going to execute "edge-detection" process in a seperate thread since it is an intensive process.During this process we need to draw detected curve (set of pixels) on top of above QImage*.(as a layer).This means we need to call drawPoint() methods outside the QT thread. Is it the best wayto use QImage for this case? What is the best way to execute QT drawing methods from another thread? thanks in advance,

  • iPhone - UIImage imageScaledToSize Memory Issue

    - by bbullis21
    I have done research and tried several times to release the UIImage memory and have been unsuccessful. I saw one other post on the internet where someone else was having this same issue. Everytime imageScaledToSize is called, the ObjectAlloc continues to climb. In the following code I am pulling a local image from my resource directory and resizing it with some blur. Can someone provide some help on how to release the memory of the UIImages called....scaledImage and labelImage. This is the chunk of code where the iPhone Intruments has shown to have the ObjectAlloc build up. This chunk of code is called several times with an NSTimer. //Get local image from inside resource NSString * fileLocation = [[NSBundle mainBundle] pathForResource:imgMain ofType:@"jpg"]; NSData * imageData = [NSData dataWithContentsOfFile:fileLocation]; UIImage * blurMe = [UIImage imageWithData:imageData]; //Resize and blur image UIImage * scaledImage = [blurMe _imageScaledToSize:CGSizeMake(blurMe.size.width / dblBlurLevel, blurMe.size.width / dblBlurLevel) interpolationQuality:3.0]; UIImage * labelImage = [scaledImage _imageScaledToSize:blurMe.size interpolationQuality:3.0]; imgView.image = labelImage;

  • CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

    - by CaboONE
    I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

  • Wordpress and Anythingslider Navigation Thumbnails

    - by Tom
    So I am using AnythingSlider in Wordpress. This is why I am trying to call the thumbnails from the original posts. Anything slider will configure thumbnail navigation like this: function formatText(index, panel) { return index + ""; } $(function () { $('.anythingSlider').anythingSlider({ navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }); }); As you can see, the navigationFormatter will allow me to format the nav (including thumbnails) however I want. For example, to format thumbnails, I could do this: navigationFormatter : function(i, panel){ // add thumbnails as navigation links return '<img src="images/th-slide-' + ['civil-1', 'env-1', 'civil-2', 'env-2'][i - 1] + '.jpg">'; } So my issue is getting the wordpress slide images to show up there dynamically, rather than in a folder (as the above example shows). For reference, this is my php query that is pulling the posts image (from a script I've already written: <img class="slider-img" style="float:left;" src="<?php if(function_exists('wp_get_post_image')){ echo wp_get_post_image(array( 'return_html' => false, 'width' => 500 )); } ?>" /> I hope this update helps. Thank you guys so much. The Stack overflow community is great!

  • [AS3] BitmapData cut-off

    - by Fristi
    Hello, I am writing a MovieClip rasterizer which rasterizes all the frames in the specified movieclip. Here's the code for rasterizing: for ( var i:int = start; i <= end; i++ ) { //goto the next frame clip.gotoAndStop( i ); //get the bounds bounds = clip.getBounds(clip); //create a new bitmapdata container bitmapData = new BitmapData( transformer.width == -1 ? bounds.width : transformer.width, transformer.height == -1 ? bounds.height : transformer.height, transformer.transparent, transformer.color ); //rotate the clip if (clip.rotation != 0) transformer.rotate( clip.rotation * (Math.PI / 180) ); //scale the clip if (clip.scaleX != 1 || clip.scaleY != 1) transformer.scale( clip.scaleX, clip.scaleY ); //translate the movieclip to its zero point if (transformer.matrix.tx == 0 && transformer.matrix.ty == 0) transformer.translateToZero( bounds ); //draw the bitmap data with the transformers bitmapData.draw( this._source, transformer.matrix, transformer.colorTransform, transformer.blendMode, transformer.clipRect, //new Rectangle(0, 0, bounds.width, bounds.height), transformer.smoothing ); //push the data on the array frames.push( bitmapData ); } Now the result is different - http://i42.tinypic.com/lfv52.jpg - (note the head and left shoe). Anyone knows what the problem is? I've seen people adding 'extra' pixels to their boundary box at the BitmapData constructor, but thats nasty imo.

  • Print raw data to a thermal-printer using .NET

    - by blauesocke
    I'm trying to print out raw ascii data to a thermal printer. I do this by using this code example: http://support.microsoft.com/kb/322091 but my printer prints always only one character and this not until I press the form feed button. If I print something with notepad the printer will do a form feed automatically but without printing any text. The printer is connected via usb over a lpt2usb adapter and Windows 7 uses the "Generic - Generic / Text Only" driver. Anyone knows what is going wrong? How is it possible to print some words and do some form feeds? Are there some control characters I have to send? And if yes: How do I send them? Edit 14.04.2010 21:51 My code (C#) looks like this: PrinterSettings s = new PrinterSettings(); s.PrinterName = "Generic / Text Only"; RawPrinterHelper.SendStringToPrinter(s.PrinterName, "Test"); This code will return a "T" after I pressed the form feed button (This litte black button here: swissmania.ch/images/935-151.jpg - sorry, not enough reputation for two hyperlinks) Edit 15.04.2010 16:56 I'm using now the code form here: c-sharpcorner.com/UploadFile/johnodonell/PrintingDirectlytothePrinter11222005001207AM/PrintingDirectlytothePrinter.aspx I modified it a bit that I can use the following code: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[1] { 13 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); Running this code has the same effekt like pressing the form feed button, it works fine! But code like this still does not work: byte[] toSend; // 10 = line feed // 13 carriage return/form feed toSend = new byte[2] { 66, 67 }; PrintDirect.WritePrinter(lhPrinter, toSend, toSend.Length, ref pcWritten); This will print out just a "B" but I expect "BC" and after running any code I have to reconnect the USB cable to make it work agian. Any ideas?

  • Data loss when downloading data from LDAP server

    - by Ricky D'Amelio
    Hi there. This question comes from a previous one I asked about handling NSData objects: http://stackoverflow.com/questions/2453785/converting-nsdata-to-an-nsstring-representation-is-failing. I have reached the point where I am taking an NSImage, turning it into NSData and uploading those data bytes to the LDAP server. I am doing this like so; //connected successfully to LDAP server above... struct berval photo_berval; struct berval *jpegPhoto_values[2]; photo_berval.bv_len = [photo length]; photo_berval.bv_val = [photo bytes]; jpegPhoto_values[0] = &photo_berval; jpegPhoto_values[1] = NULL; mod.mod_type = "jpegPhoto"; mod.mod_op = LDAP_MOD_REPLACE|LDAP_MOD_BVALUES; mod.mod_bvalues = jpegPhoto_values; mods[0] = &mod; mods[1] = NULL; //perform the modify operation rc = ldap_modify_ext_s(ld, givenModifyEntry, mods, NULL, NULL); That happens with no errors, and you can see a big blob of data when you're in the command line. My problem is, when I go to access the same data at a later stage, I am getting an image file back that's about 120 times smaller than the original image. //find the jpegPhoto attribute photoA = ldap_first_attribute(ld, photoE, &photoBer); while (strcasecmp(photoA, "jpegphoto") != 0) { photoA = ldap_next_attribute(ld, photoE, photoBer); } //get the value of the attribute if ((list_of_photos = ldap_get_values_len(ld, photoE, photoA)) != NULL) { //get the first JPEG photo_data = *list_of_photos[0]; selectedPictureData = [NSData dataWithBytes:&photo_data length:sizeof(photo_data)]; [selectedPictureData writeToFile:@"/Users/username/Desktop/Photo 2.jpg" atomically:YES]; NSLog (@"%@", selectedPictureData); Has anyone successfully done this before or can anyone see what I might be doing wrong? I appreciate anyone's help. Sorry to post so many questions! Ricky.

  • Setting up a "cookieless domain" to improve site performance

    - by Django Reinhardt
    I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

  • accelerating Wheel - psychtoolbox in matlab

    - by ariel
    Hi I am trying to write a code that will show an acceleration wheel. as long as the user press 'a' the wheel should accelerate counterclock wize. the thing is that it turn in the right direction but it doesn't accelerate. This is the code I am using . PTB-3 windows XP. img=imread('c:\images.jpg'); [yimg,ximg,z]=size(img); rot_spd = 1; larrow = KbName('a'); % modify this for Windows rarrow = KbName('b'); [w,rect]=Screen('OpenWindow',0,[0 0 0]); sx = 400; % desired x-size of image (pixels) sy = yimg*sx/ximg; % desired y-size--keep proportional t = Screen('MakeTexture',w,img); bdown=0; th = 0; % initial rotation angle (degrees) HideCursor while(~any(bdown)) % exit loop if mouse button is pressed [x,y,bdown]=GetMouse; [keyisdown,secs,keycode] = KbCheck; if(keycode(larrow)) th = th - rot_spd-1; % accelerate counterclockwise th end if(keycode(rarrow)) th = th + rot_spd+1; % accelerate clockwise th end destrect=[x-sx/2,y-sy/2,x+sx/2,y+sy/2]; Screen('DrawTexture',w,t,[],destrect,th); Screen('Flip',w); end Screen('Close',w) ShowCursor If anyone has an odea why it doesn't accelerate I'd appriciate it very much.

  • Problem in cropping the UIImage using CGContext?

    - by Rajendra Bhole
    Hi, I developing the simple UIApplication in which i want to crop the UIImage (in .jpg format) with help of CGContext. The developed code till now as follows, CGImageRef graphicOriginalImage = [originalImage.image CGImage]; UIGraphicsBeginImageContext(originalImage.image.size); CGContextRef ctx = UIGraphicsGetCurrentContext(); CGBitmapContextCreateImage(graphicOriginalImage); CGFloat fltW = originalImage.image.size.width; CGFloat fltH = originalImage.image.size.height; CGFloat X = round(fltW/4); CGFloat Y =round(fltH/4); CGFloat width = round(X + (fltW/2)); CGFloat height = round(Y + (fltH/2)); CGContextTranslateCTM(ctx, 0, image.size.height); CGContextScaleCTM(ctx, 1.0, -1.0); CGRect rect = CGRectMake(X,Y ,width ,height); CGContextDrawImage(ctx, rect, graphicOriginalImage); croppedImage = UIGraphicsGetImageFromCurrentImageContext(); return croppedImage; } The above code is worked fine but it can't crop image. The original image memory and cropped image memory i will got same(equal to original image memory). The above code is right for cropping the image?????????????????? How i cropping the image (in behind pixels should also be crop) from the center of the image???????????? I already wasting a lot of time for developing the above code , but i didn't get answer or way to find out how to crop the image.Thanks for sending me answer in advanced.

  • Inline image and caption in article - conform caption's width to image's width

    - by Micah
    Here's my code: <div class="image"> <img src="image.jpg" alt="Image description" /> <p class="caption">This is the image caption</p> </div> Here's my CSS: .image { position: relative; float: right; margin: 8px 0 10px 10px; } .caption { font-weight: bold; color: #444666; } As is above, the caption will conform to the width of div.image. My problem is often the img varies in size, from 100px width to 250px width. I'd like to make the caption width conform to the corresponding width of the image, no matter the size. While I'd love for this to be more semantic as well, I'm not sure how easy it would be to switch p.caption with img. Of course, I'd prefer that method but am taking this a step at a time. Is there some jquery code that I can use to detect the width of the image and add that width as an inline style to the caption tag? Is there a better way to do this? I'm open to suggestions.

  • C# Regex - Replace multiple characters at once without overwriting?

    - by Everaldo Aguiar
    Hello guys, I'm implementing a c# program that should automatize a Mono-alphabetic substitution cipher. The functionality i'm working on at the moment is the simplest one: The user will provide a plain text and a cipher alphabet, for example: Plain text(input): THIS IS A TEST Cipher alphabet: A - Y, H - Z, I - K, S - L, E - J, T - Q Cipher Text(output): QZKL KL QJLQ I thought of using regular expressions since I've been programming in perl for a while, but I'm encountering some problems on c#. First I would like to know if someone would have a suggestion for a regular expression that would replace all occurrence of each letter by its corresponding cipher letter (provided by user) at once and without overwriting anything. Example: In this case, user provides plaintext "TEST", and on his cipher alphabet, he wishes to have all his T's replaced with E's, E's replaced with Y and S replaced with J. My first thought was to substitute each occurrence of a letter with an individual character and then replace that character by the cipherletter corresponding to the plaintext letter provided. Using the same example word "TEST", the steps taken by the program to provide an answer would be: 1 - replace T's with (lets say) @ 2 - replace E's with # 3 - replace S's with & 4 - Replace @ with E, # with Y, & with j 5 - Output = EYJE This solution doesn't seem to work for large texts. I would like to know if anyone can think of a single regular expression that would allow me to replace each letter in a given text by its corresponding letter in a 26-letter cipher alphabet without the need of splitting the task in an intermediate step as I mentioned. If it helps visualize the process, this is a print screen of my GUI for the program: http://img43.imageshack.us/img43/2118/11618743.jpg

  • ASP.NET MVC Image refreshing

    - by user295541
    Hi, I have an Employee object which has an image property. Image class contains image metadata as image caption, and image file name. If I upload a new image for an employee on async way without full post back the new image is not appeared on the page. I use GUID to name the image file to avoid the page caching. I do the image modifying the following way: ctrEmployee employee = Repository.Get(PassedItemID); if (employee.ctrImage != null) { string fullFileName = serverFolder + employee.ctrImage.FileName; FileInfo TheFile = new FileInfo(fullFileName); if (TheFile.Exists) { TheFile.Delete(); } fileName = Guid.NewGuid() + ".jpg"; employee.ctrImage.FileName = fileName; } resizedBmp.Save(string.Format("{0}{1}", serverFolder, fileName), System.Drawing.Imaging.ImageFormat.Jpeg); Repository.Edit<ctrEmployee>(employee); ImageID = employee.Image.Value; return PartialView(UserControlPaths.Thumbnail, new ThumbnailDataModel(employee.Image.Value, 150, 150)); The partial view has an image tag which gets the saved image url string which is a GUID. Anybody has an idea what I do wrong?

  • Is using the .NET Image Conversion enough?

    - by contactmatt
    I've seen a lot of people try to code their own image conversion techniques. It often seems to be very complicated, and ends up using GDI+ function calls, and manipulating bits of the image. This has got me wondering if I am missing something in the simplicity of .NET's image conversion call when saving an image. Here's the code I have: Bitmap tempBmp = new Bitmap("c:\temp\img.jpg"); Bitmap bmp = new Bitmap(tempBmp, 800, 600); bmp.Save(c:\temp\img.bmp, //extension depends on format ImageFormat.Bmp) //These are all the ImageFormats I allow conversion to within the program. Ignore the syntax for a second ;) ImageFormat.Gif) //or ImageFormat.Jpeg) //or ImageFormat.Png) //or ImageFormat.Tiff) //or ImageFormat.Wmf) //or ImageFormat.Bmp)//or ); This is all I'm doing in my image conversion. Just setting the location of where the image should be saved, and passing it an ImageFormat type. I've tested it the best I can, but I'm wondering if I am missing anything in this simple format conversion, or if this is sufficient?

  • jQuery - Not sure which method to use, closest() and parent() don't work.

    - by Nike
    Hello, again. :) God i feel like i'm spamming stackoverflow, this is my 3rd post for today. Sorry, heh. I even posted a question regarding this before, kind of, but i've changed the code a bit since so i thought it was better to post a new question. $('.pmlist ul li h4 .toggle').click(function() { $(this).closest('.meddel').toggle(250); }); That's what i've got now. The reason why the closest() method isn't working is because the div .meddel is just next to the h4 element. And closest() only crawls right up the DOM tree, ignoring other child elements. Right? parent() works almost the same and doesn't work either. And as i only want to toggle the closest .meddel div in the element, i need something that, yeah justs grabs the nearest one, and not all of them. To clear it up a bit, here's the HTML for one list item: <li class="item"> <h4><a class="toggle">ämne</a><small>2010-04-17 kl 12:54 by <u>nike1</u></small></h4> <div class="meddel"> <span> <img style="max-width: 70%; min-height: 70%;" src="profile-images/nike1.jpg" alt="" /> <a href="account.php?usr=47">nike1</a> </span> <p>text</p> </div> </li> I have several items like that, and if i click one toggle link, i just want the nearest .meddel to be toggled, as mentioned before. Thanks. -Nike

  • How to get image's coordinate on JPanel

    - by Jessy
    This question is related to my previous question http://stackoverflow.com/questions/2376027/how-to-generate-cartesian-coordinate-x-y-from-gridbaglayout I have successfully get the coordinate of each pictures, however when I checked the coordinate through (System.out.println) and the placement of the images on the screen, it seems to be wrong. e.g. if on the screen it was obvious that the x point of the first picture is on cell 2 which is on coordinate of 20, but the program shows x=1. Here is part of the code: public Grid (){ setPreferredSize(new Dimension(600,600)); .... setLayout(new GridBagLayout()); GridBagConstraints gc = new GridBagConstraints(); gc.weightx = 1d; gc.weighty = 1d; gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right gc.fill = GridBagConstraints.BOTH; JLabel[][] label = new JLabel[ROWS][COLS]; Random rand = new Random(); // fill the panel with labels for (int i=0;i<IMAGES;i++){ ImageIcon icon = createImageIcon("myPics.jpg"); int r, c; do{ //pick random cell which is empty r = (int)Math.floor(Math.random() * ROWS); c = (int)Math.floor(Math.random() * COLS); } while (label[r][c]!=null); //randomly scale the images int x = rand.nextInt(50)+30; int y = rand.nextInt(50)+30; Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH); icon.setImage(image); JLabel lbl = new JLabel(icon); // Instantiate GUI components gc.gridx = r; gc.gridy = c; add(lbl, gc); //add(component, constraintObj); label[r][c] = lbl; } I checked the coordinate through this code: Component[] components = getComponents(); for (Component component : components) { System.out.println(component.getBounds()); }
