  • Problem in displaying image in FireFox

    - by Param-Ganak
    Hello friends, I have a JSP page on which I have a div tag in which there is a a IMG tag. Using this IMG tag I want to show an image in it. Here the source path of an image is comes from database so I assigned a JSP variable using JSP scriplet. This JSP variable have the source path of an image. This path of image may be of different machine or of same machine i.e. images are stored on different machine or on same machine i.e. on local machine on different drive. The problem is that how to give path of image stored on different machine as well as on same machine. I have tried different ways like by giving ip address of that machine. Here is the path that of local machine where the image is stored img src= file:\localhost\D:\ScannedSheets\testproj/batch1/IMG001.jpg style="z-index:1; position:absolute; top:0; left:0; width:850; height:1099" With this syntax the image is visible in Internet Explorer but With the same syntax Its not visible in FireFox, Google Chrome etc. Please Guide me in friends. Also tell me that how to give path of the image stored on different machine which works In Internet Explorer, FireFox, Google chrome etc.

  • Ajax Update Panel Not Displaying Updated Image in IE, Chrome and FireFox

    - by jmease
    I have a parent page with an Ajax Update Panel that contains an image and a button. There is a hyperlink that opens up a child page. When the child page is submitted, there is an onclientclick event that triggers a javascript function that clicks the button in the update panel on the parent page, the button's click event being the trigger for the panel as well as the event that updates the image URL. When I use this on my android tablet, it works perfectly. However, it doesn't work at all on any browser I've used on a PC (Windows XP). The Image URL updates, but the updated image doesn't display without refreshing the entire page. In IE, I can right click on the image and click Show Image and it updates. In Chrome and Firefox, I have to refresh the entire page. Why would an Ajax control only work properly on the Android OS and what could I be doing wrong that would cause the image not to redisplay on my PC without refreshing the page even though the image URL is clearly being updated properly. I suspect a caching issue, but don't know how to correct.

  • Show image on hover with PHP

    - by Sorosh
    I have a small problem with my PHP code and It would be very nice if someone could help me. I want to display an image when hovering over a link. This is the link with the PHP code that I have now: <a href="<?php the_permalink(); ?>"><?php if ( has_post_thumbnail() ) {the_post_thumbnail();} else if ( has_post_video() ) {the_post_video_image();}?></a> This code shows a image, but I want to execute this code when hovering over the link with the image: <?php echo print_image_function(); ?> The code also shows a image that belongs to a category. I don't want the initial image to disappear I simply want to show the second image on top off the first image when hovering over the first image. I don't know if it is helpful but I use Wordpress and I am not a PHP expert. I even don't know if this is going to work. Thats why I am asking if somebody can help me with this. Thanks in advance

  • Why would Copying a Large Image to the Clipboard Freeze a Computer?

    - by Akemi Iwaya
    Sometimes, something really odd happens when using our computers that makes no sense at all…such as copying a simple image to the clipboard and the computer freezing up because of it. An image is an image, right? Today’s SuperUser post has the answer to a puzzled reader’s dilemna. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Original image courtesy of Wikimedia. The Question SuperUser reader Joban Dhillon wants to know why copying an image to the clipboard on his computer freezes it up: I was messing around with some height map images and found this one: (http://upload.wikimedia.org/wikipedia/commons/1/15/Srtm_ramp2.world.21600×10800.jpg) The image is 21,600*10,800 pixels in size. When I right click and select “Copy Image” in my browser (I am using Google Chrome), it slows down my computer until it freezes. After that I must restart. I am curious about why this happens. I presume it is the size of the image, although it is only about 6 MB when saved to my computer. I am also using Windows 8.1 Why would a simple image freeze Joban’s computer up after copying it to the clipboard? The Answer SuperUser contributor Mokubai has the answer for us: “Copy Image” is copying the raw image data, rather than the image file itself, to your clipboard. The raw image data will be 21,600 x 10,800 x 3 (24 bit image) = 699,840,000 bytes of data. That is approximately 700 MB of data your browser is trying to copy to the clipboard. JPEG compresses the raw data using a lossy algorithm and can get pretty good compression. Hence the compressed file is only 6 MB. The reason it makes your computer slow is that it is probably filling your memory up with at least the 700 MB of image data that your browser is using to show you the image, another 700 MB (along with whatever overhead the clipboard incurs) to store it on the clipboard, and a not insignificant amount of processing power to convert the image into a format that can be stored on the clipboard. Chances are that if you have less than 4 GB of physical RAM, then those copies of the image data are forcing your computer to page memory out to the swap file in an attempt to fulfil both memory demands at the same time. This will cause programs and disk access to be sluggish as they use the disk and try to use the data that may have just been paged out. In short: Do not use the clipboard for huge images unless you have a lot of memory and a bit of time to spare. Like pretty graphs? This is what happens when I load that image in Google Chrome, then copy it to the clipboard on my machine with 12 GB of RAM: It starts off at the lower point using 2.8 GB of RAM, loading the image punches it up to 3.6 GB (approximately the 700 MB), then copying it to the clipboard spikes way up there at 6.3 GB of RAM before settling back down at the 4.5-ish you would expect to see for a program and two copies of a rather large image. That is a whopping 3.7 GB of image data being worked on at the peak, which is probably the initial image, a reserved quantity for the clipboard, and perhaps a couple of conversion buffers. That is enough to bring any machine with less than 8 GB of RAM to its knees. Strangely, doing the same thing in Firefox just copies the image file rather than the image data (without the scary memory surge). Have something to add to the explanation? Sound off in the comments.

  • Quitting dozens of the same process in OS X Terminal

    - by Artur Sapek
    Whenever I'm testing a python class I'm working on, I initiate and re-initiate python a lot to refresh the updates I make to the code. When I close the Terminal window later, I get a window that says I am about to quit a LOT of running instances of python. Is this a bug on terminal's part, or am I really running all those? I Ctrl-Z out of it each time but it always says [8]+ Stopped Python where the 8 is incremental and often gets into the 20's and 30's. Am I doing something stupid?

  • Utility to Monitor Kill / Restart Rogue Process?

    - by Sean O
    Hi, I need a Windows (XP/7) utility to continuously monitor always-running processes and kill them (and optionally restart them) if they hang. There are a lot of interactive tools out there (Sysinternals, most notably). But I have a program on a little-used workstation that needs to run continuously and reliably, both of which are not two of its strong suits :) It requires continual babysitting, and I'd rather just have a monitoring utility (even a paid one) that can kill/restart it on definable conditions -- e.g. CPU 80%, Status of "Not Responding", etc.

  • Set process priority to High: Dangerous?

    - by eek142
    I have read that setting something to realtime is a big no-no, so I am not going to do that. But I do have an application that I need to make sure always has the highest priority on my system as it is critical for the rest of the applications I am running. Is there any danger in setting the priority to high, which is one level below realtime? Also, how would I be able to do this by changing the shortcut target? What is the command?

  • Kill .so file process

    - by demonofnight
    I have a program, I cannot change the code. It calls some .so file's function, but don't delete the object in the end. When the owner of the program tries to update the program he kills it and send the update, but the .so file is in use so he can't update the file. It's on an AIX platform. Is it possible to force to kill the .so file? If I do a fuser -f on the file it returns nothing. Can I create another program to kill the program, is there any command to do that?

  • Background process and SIGHUP

    - by Charles Salvia
    My understanding is that a program that is associated with a terminal will receive the SIGHUP signal if that terminal is closed. This usually will terminate the program. I also know that you can use the nohup command along with the & symbol to run the program in the background, and disassociate it from the terminal so that the program is not terminated when the terminal closes (on log out.) However, suppose a program is run normally without nohup, but is then suspended using Cntl-Z. If the program is then resumed in the background using the bg command, will it receive the SIGHUP signal on log out? Or to put it another way: if I have a program which is already running, and I don't want to stop it but I'd like to log out, can I suspend it using Cntl-Z and run it in the background using bg? Or will the program be terminated when I log out?

  • Kill PHP process when connection is closed

    - by user838437
    I've posted the following question to SO, but thought there might be a server based solution. http://stackoverflow.com/questions/9053964/php-script-with-sleep-does-not-exit-on-connection-close I'm running an Ubuntu VPS to run this script, and I'm trying to get the script to die when the user closes the window/tab of his browser. There are several PHP based functions to see if the connection is still open, but none works (trust me, tested them all). Any creative ideas on how I can do this through the server maybe?

  • GD! Converting a png image to jpeg and making the alpha by default white and not black.

    - by Shawn
    I tried something like this but it just makes the background of the image white, not necessarily the alpha of the image. I wanted to just upload everything as jpg's so if i could somehow "flatten" a png image with some transparently to default it to just be white so i can use it as a jpg instead. Appreciate any help. Thanks. $old = imagecreatefrompng($upload); $background = imagecolorallocate($old,255,255,255); imagefill($old, 0, 0, $background); imagealphablending($old, false); imagesavealpha($old, true);

  • Unable to capture standard output of process using Boost.Process

    - by Chris Kaminski
    Currently am using Boost.Process from the Boost sandbox, and am having issues getting it to capture my standard output properly; wondering if someone can give me a second pair of eyeballs into what I might be doing wrong. I'm trying to take thumbnails out of RAW camera images using DCRAW (latest version), and capture them for conversion to QT QImage's. The process launch function: namespace bf = ::boost::filesystem; namespace bp = ::boost::process; QImage DCRawInterface::convertRawImage(string path) { // commandline: dcraw -e -c <srcfile> -> piped to stdout. if ( bf::exists( path ) ) { std::string exec = "bin\\dcraw.exe"; std::vector<std::string> args; args.push_back("-v"); args.push_back("-c"); args.push_back("-e"); args.push_back(path); bp::context ctx; ctx.stdout_behavior = bp::capture_stream(); bp::child c = bp::launch(exec, args, ctx); bp::pistream &is = c.get_stdout(); ofstream output("C:\\temp\\testcfk.jpg"); streamcopy(is, output); } return (NULL); } inline void streamcopy(std::istream& input, std::ostream& out) { char buffer[4096]; int i = 0; while (!input.eof() ) { memset(buffer, 0, sizeof(buffer)); int bytes = input.readsome(buffer, sizeof buffer); out.write(buffer, bytes); i++; } } Invoking the converter: DCRawInterface DcRaw; DcRaw.convertRawImage("test/CFK_2439.NEF"); The goal is to simply verify that I can copy the input stream to an output file. Currently, if I comment out the following line: args.push_back("-c"); then the thumbnail is written by DCRAW to the source directory with a name of CFK_2439.thumb.jpg, which proves to me that the process is getting invoked with the right arguments. What's not happening is connecting to the output pipe properly. FWIW: I'm performing this test on Windows XP under Eclipse 3.5/Latest MingW (GCC 4.4).

  • How do I use CSS to add a non-rectangular border around an image?

    - by KPL
    Hello people, I have three images, and they are not square or rectangular in shape. They are just like face of anyone. So, basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question. EDIT (from comments): How do I put a border around the shape of the image, not a rectangular one around the boundary, using CSS.

  • Verify burned CD image

    - by Brian
    Is there a way to verify a CD image (.iso) after it has been burned (and either the CD burning software does not have a "verify" option, or it was not used at the time of burning)? I tried ripping the CD using dd and comparing the md5sum of that image and the original, but they don't match. I didn't really expect them to, but I'm pretty sure this disc burned without errors (I just want to be sure since this is a master disc to be sent off to be duplicated).
