  • why does $.ajax(..) not work for me?

    - by dr jerry
    I'm running jquery from a file. And I'm trying to load a svg file from my localhost to populate a svg canvas. However that does not work as expected. What I do from filesystem: $.ajax({ url: url , timeout: 1000, complete: function(xml) { alert('complete'); }, success: function(xml, status, xreq) { alert('success'); }, error: function() { alert('error'); } }); the url reads: http://localhost/image.svg, when I read this url directly from an addressbar from the browser, the pages remains white but the pagesource displays the source of image.svg. Debugging the $.ajax code above, reveals that the success: method is hit, but xml response remains empty. Any help is greatly appreciated. regards, jeroen.

  • PHP FTP Upload thousands of files

    - by user275074
    Hi, I've written a small FTP class which I used to move files from a local server to a remote server. It does this by checking an array of local files with an array of files on the remote server. If the file exists on the remote server, it won't bother uploading it. The script works fine for small amounts of files, but I've noticed that the local server can have as many as 3000+ image files to transfer, this seems to cause the script to flop and only transfer a 100 or so. How can I modify the script to handle potentially thousands of image transfer files?

  • How to store images efficiently (memory-wise) while still being able to process them

    - by Sheeo
    I'm working on a silverlight project where users get to create their own Collages. The problem When loading images into memory, I'm using BitmapImage so that they can be displayed directly with the Image control--but they're locked in afterwards. So I've tried storing them seperately aswell, but that just sucks up huge amounts of RAM. So in short, is there a class that'll let me store JPEG images, be able to show them with the image control, and still be able to export it afterwards? All this needs to be efficient--i.e. I'd rather not want any copying to ARGB arrays or use the WriteableBitmap to copy them over. I require to work with large collections of images, up to 300 at most. Any help apreciated!

  • Right method to build a online whiteboard - JAVA

    - by Nikhar Sharma
    I am building a whiteboard, which would have a server(teacher) and clients(students). Teacher would draw something on his side, which will be shown exactly same to the students. I want to know which component i should use to do the drawing? i am currently drawing on JPanel . I want the screen of Server gets copied on the clients, so for that what could be the right method to do this? option1: i save the JPanel as image, and send thru socket, and loads it on the screen of client, also it always saves the background image only, not what the user has drawn onto it. OR option2: both server and client JPanel dimensions are same, so i just send the new coordinates drawn everytime thru socket, with some protocol to understand whether it is rubber or pencil.. Any help would be appreciated.

  • Hiding Text in ie7

    - by user356849
    So I have this text generated by a javascript plugin. <a class="className">Text</a> a.className { background: url(images/a-image.png) no-repeat; } But the "Text" shows on top of the image... Now... with any respectable web browser, I can use color: rgba(0,0,0,0); to solve the problem, but IE7 doesn't obey standards of any sort. Any ideas?

  • Mac OSX: Passing a link to file from user process to kernel module.

    - by Inso Reiges
    Hello, I need to pass a link to file from a user process to the OSX kernel driver. By link i mean anything that uniquely identifies a file on the local filesystem. I need that link to do I/O on that file in kernel. The most obvious solution seems to pass a file name and use a VFS vnode lookup. However i noticed, that Apple Disk Images helper process passes a raw data array for image-path property to driver when attaching a disk image file: <2f 56 6f 6c 75 6d 65 73 2f 73 74 6f 72 61 67 65 2f 74 65 73 74 32 2e 64 6d 67> What is that diskimages-helper passes to the kernel driver? Some serialized type perhaps? If yes, what type is it and how can i use it?

  • IE - Color transparent not working

    - by poru
    Hello, I have a problem with the IE (what else?): I generate content with CSS which has also a background-image. I looks like that: #nav ul li:after { content: "--"; position: relative; z-index: 99; background: transparent url(image.png); color: transparent; } The text color is in non-IE-browsers transparent, but in all IE browsers it's black and you could see it. How could I make the text transparent/unvisible? I tried already: visibility - opacity - filter - text-indent ... But none did his job right, either it disappears (with it background which I need) or the attribute doesn't apply.

  • Bitmap manipulation in C++ on Windows

    - by Oliver
    Hi, I have myself a handle to a bitmap, in C++, on Windows: HBITMAP hBitmap; On this image I want to do some Image Recognition, pattern analysis, that sort of thing. In my studies at University, I have done this in Matlab, it is quite easy to get at the individual pixels based on their position, but I have no idea how to do this in C++ under Windows - I haven't really been able to understand what I have read so far. I have seen some references to a nice looking Bitmap class that lets you setPixel() and getPixel() and that sort of thing, but I think this is with .net . How should I go about turning my HBITMAP into something I can play with easily? I need to be able to get at the RGBA information. Are there libraries that allow me to work with the data without having to learn about DCs and BitBlt and that sort of thing?

  • C++ How do I properly use getline for ifstream members.

    - by John
    Ok so I have a problem with getline. I have a file that contains a couple strings. I created it by myself and I have each string on a seperate line. Ex. textfile.txt Line 1 Line 2 Line 3 Line 4 //Little snip of code ifstream inFile("textfile.txt"); getline(inFile, string1); When I debug the program and ask it to print out string1 it shows that "Line 1\r" is saved into string1. I understand that it's from me actually hitting enter when I created the file. This problem causes my program to have a segmentation fault. I know my code works because if I use ofstream to write the file first and then i read it in, it works. So for my quesiton, is their anyway to use the getline function without it picking up the escape sequence \r? If i am not clear just let me know.

  • Gluing tiles together using imagemagick's montage command

    - by AP257
    This seems like it might be a reasonably common question, so I'm going to ask it using as many keywords as I can think of! I have a bunch of (well, nine) tile jpegs, with standard tile filenames. Each jpeg is 220x175 pixels: (top row) tile_1_0_0.jpg tile_1_1_0.jpg tile_1_2_0.jpg (middle row) tile_1_0_1.jpg tile_1_1_1.jpg tile_1_2_1.jpg (bottom row) tile_1_0_2.jpg tile_1_1_2.jpg tile_1_2_2.jpg How can I use imagemagick/montage to 'glue' or join them all together to make a single, coherent image? I don't want to resize them at all, so I guess the final image should be 660x525. That would be montage with no framing, shadowing, bordering, etc - just the nine original images, glued together to make a single jpeg. I know it should be something along these lines, but I'm struggling with getting the order and sizing right: montage +frame +shadow +label -tile 3x3 -geometry <options> *.jpg joined.jpg

  • Get redirected url from code

    - by Skoder
    Hey, I'm using an API which, given a url, redirects to a file on the server. The file names have "_s,_m and _l" appended to the end (small, medium, large). However, since the url's querystring is parsed dynamically, I don't retrieve the actual file name. The image displays correctly, but is it possible to retrieve the filename of the image file from the code? (i.e. where the url has redirected to)? e.g. http://api.somesite.com/getimage?small (this is what I enter) "http://somesite.com/images/userimage_s" (this is where it redirects to. I would like to get this address from code) Thanks for any advice

  • Captcha Alternative, how secure?

    - by aslum
    I do the web page for my local library, and I was thinking it might be kind of appealing to have a "custom" captcha based on book covers. So serve up one of several dozen book covers, and have the patron filling out the form type the book title to prove they're human. Assuming I stripped the title/author info from the image and filename, would that be enough? Would the fact that it was a unique system on a fairly small website be enough to make it effective? Just how tricky are the spam bots these days? Would having the image name be the ISBN # be too obvious?

  • Interface Builder hang up on retina images

    - by Jim
    In my app I create 2 folders for images "Standard" and "Retina" where I put a lot of images for my app. When I open one of my xib file, Interface Builder hang up... I found that if I remove Retina Image that is used by this xib, then IB will open xib without any problem... This problem occurs only with 1 xib file, another xib files can be opened without any problems. What can be the reason of hang up? Can image be bad? Or maybe I shouldn't put Retina Images to "Retina" folder? What can be the reason? Thanks...

  • jQuery: resizing element cuts off parent's background

    - by Justine
    Hi, I've been trying to recreate an effect from this tutorial: http://jqueryfordesigners.com/jquery-look-tim-van-damme/ Unfortunately, I want a background image underneath and because of the resize going on in JavaScript, it gets resized and cut off as well, like so: http://dev.gentlecode.net/dotme/index-sample.html - you can view source there to check the HTML, but basic structure looks like this: <div class="page"> <div class="container"> div.header ul.nav div.main </div> </div> Here is my jQuery code: $('ul.nav').each(function() { var $links = $(this).find('a'), panelIds = $links.map(function() { return this.hash; }).get().join(","), $panels = $(panelIds), $panelWrapper = $panels.filter(':first').parent(), delay = 500; $panels.hide(); $links.click(function() { var $link = $(this), link = (this); if ($link.is('.current')) { return; } $links.removeClass('current'); $link.addClass('current'); $panels.animate({ opacity : 0 }, delay); $panelWrapper.animate({ height: 0 }, delay, function() { var height = $panels.hide().filter(link.hash).show().css('opacity', 1).outerHeight(); $panelWrapper.animate({ height: height }, delay); }); }); var showtab = window.location.hash ? '[hash=' + window.location.hash + ']' : ':first'; $links.filter(showtab).click(); }); In this example, panelWrapper is a div.main and it gets resized to fit the content of tabs. The background is applied to the div.page but because its child is getting resized, it resizes as well, cutting off the background image. It's hard to explain so please look at the link above to see what I mean. I guess what I'm trying to ask is: is there a way to resize an element without resizing its parent? I tried setting height and min-height of .page to 100% and 101% but that didn't work. I tried making the background image fixed, but nada. It also happens if I add the background to the body or even html. Help?

  • Will the app file be sync from dmgr side after we remove it from installedApps path in Websphere?

    - by wing2ofsky
    do you know whether the app file will be sync from dmgr side and regenerated after we remove it from installedApps path? i've got one issue recently from customer. That is, they uploaded one image file into WASNode installedApps app path manually. Afterwards, they removed that file manually again from installedApps app path. But after restarting the Application server process, that file has been regenerated under same installedApps path. So i suspect that file maybe has been resync from dmgr node, like app file under applications folder. However, first of all, i don't see that image file within application ear file from DMGR applications folder. Moreover, i made a test myself, if i deleted file from installedApps app path, that file never be regenerated any more even though the node sync completed. So does anybody know why? Thanks in advance

  • Zooming to UIView and it's sub-views

    - by leon
    Hi, I have a UIView which I can zoom to (as it is set as a subview of UIScrollView). UIView has UILabel, UITextField, etc. If I just zoom to the UIView, then of course label and text field get fuzzy (the same effect if you are zooming to the image file without changing image resolution). To solve the problem I need to increase the font size and sizes of the UILable and UITextField in according to the scale used to zoom in (scale is passed as a param by the UIScrollView). This is where I am getting confused. Changing frame (by increasing it width and height by zooming scale) I get all my elements (sub-views) repositions (because changing frame effects center and bounds) Question: 1. What would I need to do to zoom in to the sub-views and just increase the sub-view sizes while keeping them in the exactly the same position? thanks

  • How to query data from a password protected https website

    - by Addie
    I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET. The url of the site is: https://www2.emidas.com/default.asp. I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query. System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://www3.emidas.com/users/<username>/file.csv"); Here is the request sent to the site for authentication. I've angle bracketed the real userid and password.

  • IE6 PNG transparency fix with Backgroud positioned

    - by durilai
    So I am using this to fix PNG transparency on background images in IE6 ul li a { background-image: url('/NewSite/Content/Images/Sprite.png'); background-repeat: no-repeat; background-position: 0 -48px; background-image: none; filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src=/NewSite/Content/Images/Sprite.png, sizingMethod='crop'); } This works great, however I have run into a problem when trying to implement this with a sprite. The fix ignores the positioning and renders as if the position was top right. Is there a way to force background position or a better way to do this. I would prefer to not use JavaScript or change to gifs. Any help is appreciated!
