  • Flash AS3: position loaded images from loop based on image height

    - by HeroicNate
    I'm trying to dynamically stack images that are being pulled in via an xml file. Below is what I'm doing, and it almost works. The problem is that it only seems to fire off the event complete function on the very last one, instead of going for all of them. Is there a way to make it run the even.complete function for each image? function aboutfileLoaded(event:Event):void { aboutXML = new XML(aboutTextLoader.data); for(var l:int = 0; l < aboutXML.aboutimages.image.length(); l++) { imageLoader = new Loader(); imageSource = aboutXML.aboutimages.image[l]; if (imageSource != "") { this.imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, aboutimageLoaded); this.imageLoader.load(new URLRequest(imageSource)); //aboutBox.aboutContent.addChild(imageLoader); //imageLoader.y = imageYpos; //imageYpos = imageYpos + 50; } } } function aboutimageLoaded(event:Event):void { aboutBox.aboutContent.addChild(imageLoader); this.imageLoader.y = imageYpos; imageYpos = imageYpos + this.imageLoader.height; }

  • 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

  • jQuery Syntax Error - Trying to detect viewport size and select background image to use w/CSS

    - by CuppyCakes
    Hi all. Please be gentle, I'm still learning. I imagine that the solution to my problem is simple and that perhaps I have just been in front of the computer too long. I am trying to detect the size of the viewport, and then use a different sized image for a background on an element depending on the size of the viewport. Here is what I have so far: $(document).ready(function(){ var pageWidth = $(window).width(); if ( pageWidth <= 1280 ) { $('#contact').css('background-image', 'url(../images/contact_us_low.jpg)'); } elseif ( pageWidth > 1280 ) { $('#contact').css('background-image', 'url(../images/contact_us_high.jpg)'); } }); Error: missing ; before statement [Break on this error] elseif ( pageWidth 1280 ) {\n (Line 7) To me it seems like all of my semi-colons are in the right place. Two questions: Am I going about solving the problem in a sensible way? To me a simple conditional should solve this background problem, as the code is merely selecting between two images based on what size it detects the viewport to be. Can you please help point out my n00b syntax error? Sometimes it really does help to have an extra pair of eyes look at something like this, even if small. Thank you kindly for your advice, I will continue poking and perusing the docs I have available to me.

  • how to use php to include an image in a word file?

    - by altvali
    Hi all! Somebody has asked me to make an app in php that will generate a .doc file with an image and a few tables in it. My first approach was: somethingsomething else cevaaltceva'); fclose($fh); ? This uses the data uri technique of embedding an image. This will generate an html file that will be rendered ok in web browsers but the image is missing in Microsoft Office Word, at least in the standard setup. Then, while editing the file with Word, i've replace the image with an image from file and Microsoft Word changed the contents of the file into Open XML and added a folder, new_files where he put the imported image (which was a .png), a .gif version of the image and a xml file: Now this isn't good enough either since i want this to be all kept in a single .doc file. Is there a way to embed an image in an OpenXML-formatted .doc file? Any help will be much appreciated.

  • Dynamically adjust padding on an image?

    - by Cory
    What I'm basically attempting to do is dynamically change a padding value for a scrubber image based on player position data provided by an app. I have been able to leverage the provided number to dynamically increase the width of a progress overlay image and create a progress bar, but I would like a scrubber diamond at the leading edge of the progress bar. To do this, I have positioned the scrubber diamond at the same starting point as the progress overlay and would like to increase the padding on the diamond at the same rate as the width is increasing for the progress overlay, allowing them to pace each other with the scrubber diamond moving as the song plays. Any help with the script necessary to manipulate padding-left dynamically would be very much appreciated. var progress = Ecoute.playerPosition(); var width = 142.5 / length * progress + 1.63; EcouteSel('Progression').width = width.toString(); EcouteSel('Scrubber').style('padding-left', 'width'); We define progress as the player position, width as a function of the progress and then apply that function to the ID applied to the progress over lay image. But how do I accomplish that for padding-left? style.paddingLeft ...based functions have broken the controller outright. I'm at a loss and any help would be appreciated.

  • Cocoa button won't display image

    - by A Mann
    Just started exploring Cocoa so pretty much a total noob. I've written a very simple game. Set it up in Interface Builder and got it working fine. It contains a number of buttons and I'm now trying to get the buttons to display images. To start with I'm trying to get an image displayed on just one of the buttons which is called tile0 . The image file (it's nothing but a green square at the moment, but I'm just trying to get that working before I attempt anything more exotic) is sitting in the same directory as the class file which controls the game. I have the following code sitting in my wakeFromNib method: NSString *myImageFileName = [[NSString alloc] init]; myImageFileName = @"greenImage.jpg"; NSImage *myImage = [[NSImage alloc] initByReferencingFile:myImageFileName]; [tile0 setImage: myImage]; Trouble is, the game runs fine, but the image isn't appearing on my button. Is there someone who could kindly tell me if I'm doing something obviously wrong? Many Thanks.

  • User clicks on Image, video starts playing

    - by cf_PhillipSenn
    I have an image, and I would like to make the image link to an embedded YouTube video, such that if the user clicks on the image, it starts playing in the place where the picture used to be. <div id="myvideo"> <a href="http://www.youtube.com/watch?v=Msef24JErmU&playnext_from=TL&videos=dgzKE_Lyv7o"> <img src="starryeyedsurprise.jpg"></a> </div> Something like what the above code does, except not just hyperlink to it. So I know I have to have javaScript replace what's in #myvideo with: <object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/Msef24JErmU&hl=en_US&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/Msef24JErmU&hl=en_US&fs=1&rel=0&color1=0x2b405b&color2=0x6b8ab6" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object> And then automatically start playing. I guess I don't need it to be a YouTube video per se, I could just host the video on my own site (it's so low volume that I don't have to worry about serving up a video every once in a while).

  • Problem with php GD image not creating

    - by ThinkingInBits
    With the following code, my browser is returning 'image not created or saved'. I assure you the location of the image exists. So the line within the if statement is returning false for some reason, and yes GD is installed. Any ideas? if ($img = @imagecreatefromjpeg("/var/www/images/upload/1/1.jpg")) { $image_width = imagesx($img); $image_height = imagesy($img); $target_width = 150; $target_height = 150; if ($image_width > $image_height) { $percentage = ($target_width / $image_width); } else { $percentage = ($target_height / $image_height); } $new_image_width = round($image_width * $percentage); $new_image_height = round($image_height * $percentage); $imgResized = imagecreatetruecolor($new_image_width, $new_image_height); imagecopyresampled($imgResized, $img, 0, 0, 0, 0, $new_image_width, $new_image_height, $image_width, $image_height); imagejpeg($imgResized, $this->path, 100); imagedestroy($img); imagedestroy($imgResized); $this->storeThumbnailLocation(); } else { die ("image was not created or saved"); }

  • Out of disk space - /boot at 100%

    - by uvasal
    My /boot is at 100%. When I run aptitude search ~ilinux-image I'm getting loads of unused images. When I try to delete one of them (after checking which one is currently in use by doing uname -r), e.g apt-get autoremove linux-image-3.2.0-44-generic I get: Reading package lists...

  • Lenovo Windows 8 EFI restore from image

    - by anderhil
    First time here. I have bought e530 with windows 8 and the first hour of work with it i have a problem. I have ssd with windows 7 which i want to use with my new e530. I have made a sysprep of win 7 and installed ssd to the e530. The HDD which was inside e530 i want to use as second hdd instead of my DVD Drive. I connected this HDD through usb-to-sata adapter to copy some files from ssd to the hdd. Unfortunately it didn't see the file system on the HDD (but first time i have booted to it and first boot into Windows 8) I've made some mistakes and i corrupt the filesystem on the hdd. I tried bunch of tricks to recover the GPT, but it didn't work. I have managed to recover the Lenovo_Recovery partition to my ssd using recovery tools. And now I'm stuck, with this new things to me - EFI, GPT, etc i don't how this stuff works, and i have been trying to understand this for hours - but nothing seems to work. I want to restore the Windows 8 to the hdd, so it is there alive. What i have done so far: Formated the HDD I took the PBRALL file from the Lenovo_Recovery " convert gpt create partition Primary size=1000 ID=DE94BBA4-06D1-4D40-A16A-BFD50179D6AC gpt attributes=0x8000000000000001 assign letter=W format quick LABEL=WINRE_DRV create partition efi size=260 assign letter=s format quick fs=fat32 LABEL=SYSTEM_DRV create par msr size=128 create partition primary noerr assign letter=t format quick LABEL=Windows8_OS shrink desired=12197 create partition Primary ID=DE94BBA4-06D1-4D40-A16A-BFD50179D6AC gpt attributes=0x8000000000000001 assign letter=q format quick LABEL=Lenovo_Recovery " it recreated the partitions copied contents of SDRIVE.zip to SYSTEM_DRV partition copied contents of WDRIVE.zip to WINRE_DRV partition Copied restored Lenovo_Recovery back to Lenovo_Recovery partition So now I have 3 system partitions: SYSTE_DRV BOOT boot.sdi EFI BOOT bootx64.efi LenovoBT.efi Lenovo ... Microsoft ... WINRE_DRV\Recovery\WindowsRE\winre.wim Lenovo_Recovery (whic contains install.wim and bunch of other things) So i put back the HDD inside the laptop and tried to boot - but nothing works. It just doesn't boot to anything - no errors - nothing at all. When I choose this HDD manually for boot - just black screen blinks and that's all - it returns back to the devices boot menu. SYSTEM_DRV is EFI partition, so I don't understand why it doesn't boot, it has files needed inside. Can anybody tell me what should be done to make it boot to recovery console or smth like that? How to restore the Windows 8 from the Lenovo_Recovery install.wim image? As I understand I have all the files where they should be, but why it doesn't work? How to troubleshoot such things? Also, if somebody has good link where EFI booting process is explained in details that would be great. Cause i still don't understand how it knows what partition to boot?

  • Fitting an Image to Screen on Rotation iPhone / iPad ?

    - by user356937
    I have been playing around with one of the iPhone examples from Apple' web site (ScrollViewSuite) . I am trying to tweak it a bit so that when I rotate the the iPad the image will fit into the screen in landscape mode vertical. I have been successful in getting the image to rotate, but the image is larger than the height of the landscape screen, so the bottom is below the screen. I would like to image to scale to the height of the landscape screen. I have been playing around with various autoSizingMask attributes without success. The imageView is called "zoomView" this is the actual image which loads into a scrollView called imageScrollView. I am trying to achieve the screen to rotate and look like this.... olsonvox.com/photos/correct.png However, this is what My screen is looking like. olsonvox.com/photos/incorrect.png I would really appreciate some advice or guidance.

  • Why is Adobe Flash Player downloaded as a ".dmg.mdlp" file?

    - by dpddt
    When I download the current Adobe flash player installer from the Adobe website using Safari 6.0.1 under OSX 10.8.2, I end up with a file named 'install_flash_player_osx.dmg.mdlp' in my downloads folder. I am curious as to why the .mdlp extension is being added to the disk image containing the flash player installer, which has always terminated with the .dmg extension in the past. The only program which uses the .mdlp extension that I am aware of is matlab; matlab is installed on this machine and it is the program the OS would like to use to open the file. I have not seen OSX, or any component thereof, replace or append file extensions in the past and I am able to download .dmg files from other websites without this phenomenon occurring. Note that I am not interested in suggestions regarding the opening of the file, but rather an explanation as to why the .mdlp extension is being applied in the first place, whether it be by the local machine or Adobe.

  • Convert color photos of documents to good black-and-white images?

    - by Norman Ramsey
    Since I don't have a copier or scanner, I'm using an 8 megapixel camera to copy documents. This works pretty well except they need a lot of processing afterward. I'd like to get from a photo to a bitmap, but using djpeg -grayscale -pnm photo.jpg | pgmtopbm -threshold -value XXX does not work so well, for two reasons: It's hard to guess what XXX should be, and XXX is different for different photos. Illumination varies, and sometimes a single threshold isn't what's right for the image. How can I do better? The ideal solution will be fully automatic command-line program that I can run on Linux. (I have already written a program to remove dark pixels from the edges of images.)

  • How to install Mac OS X Snow Leopard server on any virtual machine with DMG?

    - by Eonil
    I'm trying to install Mac OS X Snow Leopard Server on VirtualBox. I know this is duplicated question, however another questions have no fine answer. I'm trying to install on VirtualBox on iMac. So this is pretty legal. But the problem is I want to install with DMG image. Because installing DVD drive is too slow, and I have to install Mac OS X many times. And taking DVD disc from box is annoying too. But VirtualBox fails installing. It couldn't load kernel. It installs well with DVDs. Is there any way to do this? I'm considering using other VM solutions like Parallels or VMWare if they can support install from DMG images well. If you know about them certainly, please let me know.

  • How do I make a USB stick from which to install different OS's?

    - by Hanno Fietz
    Recently, I have made a number of USB sticks to install OS's (several Linux flavors, BSD, Windows) from, on machines that didn't have CD drives. Now, I would prefer to not overwrite the install USB sticks all the time, since it's handy to have them, but neither do I want to pile up USB sticks that I only need every 6 months. It would be great to have a bootable USB stick that fires up some minimal system, lets you choose an ISO image and then reboots from there. How would I go about this? Do I use some minimal Linux? Is there some kind of modified / specialized boot loader? Can I set up GRUB to do this? Should I use virtualization?

  • MS Paint: how to enter proper text?

    - by Peter Mortensen
    How do I enter normal text in Microsoft Paint? Normally I don't have any problems adding text to an image in Paint. But I ran into this problem: The text is supposed to be "abcdefd" (entered in a text editor and pasted). The same characters appear if typed directly. So apparently it is using some other character set. How do I restore normal operation? Platform: MS Paint 5.2, Windows XP Professional x64 SP2, 8 GB RAM.

  • mirroring linux server to external usb harddrive

    - by DuPie
    My google-fu must be sucking. i havent been able to find a good solution for the following: numerous Linux server on commodity hardware Trying to do a recovery mirror copy to external harddrives External harddrives are smaller than source harddrives, but larger than data External drives are connected via usb2 (slow) Servers range from 20GB of data to 400GB of data Servers are remote, so hands on access is a pain need to copy boot files. empty external drives currently Basicly, looking for a way to do use a ghosting solution from INSIDE a running linux server to an external harddrive, without booting a cd etc. the rsync/cpio solutions i've looked at dont work great with grub/dev/proc etc. I understand that since the system isnt offline, it wont be a "mirror" image as files change, but thats ok. Are there any free/commercial products that would work?

  • Make a mosaic picture out of 900 images

    - by unor
    I have ~ 900 pictures (mostly photos) of varying sizes. Now I want to create one big picture that includes all 900 pictures in a small thumbnail-like resolution. The tool should automatically resize the thumnails so that everything fits. All pictures should be added next to each other, so there should be no border/padding. Each picture should be included exactly one time! (however, it would be okay to omit a few so that there is no empty space) I'm looking for a tool (FLOSS, for GNU/Linux) that can do the job. I tried Metapixel, but it needs an input image that should be "resembled" by the thumbnails, and it only uses a selection of all pictures. I found montage, but couldn't get a result yet, because my system was unresponsible for hours after starting it. Maybe there are some tweaks? AndreaMosaic is recommended in this answer, but it's not FLOSS (and needs Wine to run it on GNU/Linux).

    I have a lot of image files, it's all I want to upload to RackSpace cloud files about a million in a single directory the fastest and most efficient way. but I'm use uploading python-cloudfiles script is very slow and I want to know different ways or python script code. because one by one connection upload is very slow. I think one files tar and uncompress directory is better way. but cloudfiles do not support this way. Who know any other way?

But at a certain point of the installation, an error occurs: Impossible to install kernel. a compatible kernel version is missing... … or something like that. I see that the image ISO of the DVD is less than 4GB, but is impossible that there is no compatible kernel version for the system. I have an Asus X53Sc with Intel core I7-2630QM, Geforce GT 520MX.

  • VS2010 "An item with the same key has already been added"

    - by fneep
    I recently installed Visual Studio 2010 and copied and converted an old VS2005 solution to VS2010 When I edit this solution, if I try to change a control's .image property, VS2010 creates a message box telling me that "An item with the same key has already been added" (screenshot below), and won't let me browse for an image. I can add images for any other solution, even others ported from VS2005, but not this one. Any idea what I'm doing wrong?
