  • TIF opens via IE, but not within a page

    - by tsilb
    I have a picture: http://www.kconnolly.net/Gallery/Panoramas/Mountainscapes/DSCN2049_stitch_sm.tif Which loads fine when I paste it into my address bar. However, when I embed it within a Page, I get a broken image icon. However, all browsers treat it as a download. Conversely, this image, which was made the same way, works fine when I embed it within a Page. Browsers treat this as a Document and not as a Download: http://www.kconnolly.net/Gallery/Panoramas/Mountainscapes/DSCN2060_stitch_sm.tif Why is that?

  • rotate pdf by a certain degree in adobe acrobat

    - by user15660
    I imported a .jpg image into adobe acrobat to convert it into PDF form with textboxes and stuff. the scanned .jpg is tilted and has to be rotated 5 deg. anti-clockwise. I know how to do this on image editor like paint.net. But I want to do this on PDF itself. is there anyway to rotate document/images in PDF by any other degree other than 90,180 or 270? thanks in advance

  • How can I transfer a user state of a win7 machine that won't boot?

    - by askvictor
    I have a windows 7 machine that won't boot completely, even in safe mode. I want to re-image the machine using a generic software image, but would like to keep the user data (including settings etc) that are on there ala Windows Easy Transfer. I can mount the hard disk on another machine - can I use Easy Transfer to transfer the user state of an account on the non-booted OS? Or do I need explore USMT?

  • My PNG has transparency, but after saving with PHP GD, transparency is lost [closed]

    - by Harry Stroker
    I found the solution to my problem. See below the original post and completely at the bottom my solution. I made a stupid mistake :) First I crop an image and then save it to a png file. Right after this, I also show the image. However, the saved png does not have transparency and the shown one has. What is going on? $this->resource = imagecreatefrompng($this->url); imagealphablending($this->resource, false); imagesavealpha($this->resource, true); $newResource = imagecreatetruecolor($destWidth, $destHeight); imagealphablending($newResource, false); imagesavealpha($newResource, true); $resample = imagecopyresampled($newResource,$this->resource,0,0,$srcX1,$srcY1,$destWidth,$destHeight,$srcX2-$srcX1, $srcY2-$srcY1); imagedestroy($this->resource); $this->resource = $newResource; // SAVING imagepng($this->resource, $destination, 100); // SHOWING header('Content-type: image/png'); imagepng($this->resource); The reason I also save the image is for caching. If the script is executed on a png, it saves a cached png. Next time the image is requested, the png file will be shown, but it has lost its transparency. Even stranger: When I save that cached png image as (within Firefox), it saves it suddenly as a jpg, even though the extension was png. Downloading the cached png using chrome and opening it in Photoshop gives the error: "file-format module cannot parse the file". I will show you the shown PNG and the generated PNG: http://www.foodmuseum.nl/SaveProblemTransparency.png Once I try to show that saved PNG with the GD library, it gives me an error. EDIT NO NO NO NO THIS IS NOT A DUPLICATE!!!... I ALREADY USED THEIR SOLUTION. The solution in the supposedly duplicate works for showing my image. But I also try to save it with the exact same resource, but then it has no transparency. EDIT 2 - SOLUTION I found out what the problem was. It was a stupid mistake. The script I provided above were cut out of a class and placed as sequential code, while in real this is not what exactly happened. The save image function: function saveImage($destination,$quality = 90) { $this->loadResource(); switch($extension){ default: case 'JPG': case 'jpg': imagejpeg($this->resource, $destination, $quality); break; case 'gif': imagegif($this->resource, $destination); break; case 'png': imagepng($this->resource, $destination); break; case 'gd2': imagegd2($this->resource, $destination); break; } } However... $extension does not exist. I fixed it by adding: $extension = $this->getExtension($destination);

  • Saving images only available when logged in

    - by James
    Hi, I've been having some trouble getting images to download when logged into a website that requires you to be logged in. The images can only be viewed when you are logged in to the site, but you cannot seem to view them directly in the browser if you copy its location into a tab/new window (it redirects to an error page - so I guess the containing folder has be .htaccess-ed). Anyway, the code I have below allows me to log in and grab the HTML content, which works well - but I cannot grab the images ... this is where I need help! <? // curl.php class Curl { public $cookieJar = ""; public function __construct($cookieJarFile = 'cookies.txt') { $this->cookieJar = $cookieJarFile; } function setup() { $header = array(); $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/gif;q=0.8,image/x-bitmap;q=0.8,image/jpeg;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: en-us,en;q=0.5"; $header[] = "Pragma: "; // browsers keep this blank. curl_setopt($this->curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7'); curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header); curl_setopt($this->curl, CURLOPT_COOKIEJAR, $this->cookieJar); curl_setopt($this->curl, CURLOPT_COOKIEFILE, $this->cookieJar); curl_setopt($this->curl, CURLOPT_AUTOREFERER, true); curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true); curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true); } function get($url) { $this->curl = curl_init($url); $this->setup(); return $this->request(); } function getAll($reg, $str) { preg_match_all($reg, $str, $matches); return $matches[1]; } function postForm($url, $fields, $referer = '') { $this->curl = curl_init($url); $this->setup(); curl_setopt($this->curl, CURLOPT_URL, $url); curl_setopt($this->curl, CURLOPT_POST, 1); curl_setopt($this->curl, CURLOPT_REFERER, $referer); curl_setopt($this->curl, CURLOPT_POSTFIELDS, $fields); return $this->request(); } function getInfo($info) { $info = ($info == 'lasturl') ? curl_getinfo($this->curl, CURLINFO_EFFECTIVE_URL) : curl_getinfo($this->curl, $info); return $info; } function request() { return curl_exec($this->curl); } } ?> And below is the page that uses it. <? // data.php include('curl.php'); $curl = new Curl(); $url = "http://domain.com/login.php"; $newURL = "http://domain.com/go_here.php"; $username = "user"; $password = "pass"; $fields = "user=$username&pass=$password"; // Calling URL $referer = "http://domain.com/refering_page.php"; $html = $curl->postForm($url, $fields, $referer); $html = $curl->get($newURL); echo $html; ?> I've tried putting the direct URL for the image into $newURL but that doesn't get the image - it simply returns an error saying since that folder is not available to view directly. I've tried varying the above in different ways, but I haven't been successful in getting an image, though I have managed to get a screen through basically saying error 405 and/or 406 (but not the image I want). Any help would be great!

  • Android: Set a random image using setImageResource

    - by Tom Jones
    I need a help with setting a random image using setImageResource method. In the drawable folder, I have a jpeg file named photo0.jpg, photo1.jpg...photo99.jpg. And the following code works: int p = R.drawable.photo1; image.setImageResource(p); The above will display photo1.jpg but I want to show a random image. I tried the following but it doesn't work. String a = "R.drawable.photo"; int n = (int) (Math.random()*100) String b = Integer.toString(n); String c = a+b; int p = Integer.parseInt(c);//checkpoint image.setImageResource(p); It seems like the string "R.drawable.photoXX" isn't being changed to integer at the checkpoint. Could someone please teach me a right code? Thank you in advance.

  • How to show an image on jasper report?

    - by spderosso
    Hi, I want to show an image on a jasper report. I have the following on the .jrxml: <image> <reportElement x="181" y="0" width="209" height="74"/> <imageExpression class="java.lang.String"><![CDATA["logo.jpg"]]></imageExpression> </image> The image logo.jpg is in the same directory as the .jrxml. By just putting that it didn't work for me. I googled a bit and found out that jasper report considers what i put on the .jrxml as a relative path to the JVM directory and that to change this I need to pass as a "REPORT_FILE_RESOLVER" parameter a FileResolver that returns the file. So, I did the following in my .java (is located in same place as the .jrxml and the image) FileResolver fileResolver = new FileResolver() { @Override public File resolveFile(String fileName) { return new File(fileName); } }; HashMap<String, Object> parameters = new HashMap<String, Object>(); parameters.put("REPORT_FILE_RESOLVER", fileResolver); ... Which should return the expected file, but I still get a net.sf.jasperreports.engine.JRException: Error loading byte data : logo.jpg at net.sf.jasperreports.engine.util.JRLoader.loadBytes(JRLoader.java:301) at net.sf.jasperreports.engine.util.JRLoader.loadBytesFromLocation(JRLoader.java:479) at net.sf.jasperreports.engine.JRImageRenderer.getInstance(JRImageRenderer.java:180) ... What am I doing wrong? Thanks!

  • UItabBarItem highlight state image

    - by Paul Solomon
    I'd like to be able to change the highlighted state image on an UITabBarItem when it is selected? Is it possible to subclass and access this? or do I need to roll my own navigation code? - start edit I didn't articulate what I was looking for earlier. I am looking for the semi-transparent white overlay reference that the device adds to the selected state/image of the UITabBar. See image! http://solomon71.com/images/UITabBarItem.png

  • Interpolation and Morphing of an image in labview and/or openCV

    - by Marc
    I am working on an image manipulation problem. I have an overhead projector that projects onto a screen, and I have a camera that takes pictures of that. I can establish a 1:1 correspondence between a subset of projector coordinates and a subset of camera pixels by projecting dots on the screen and finding the centers of mass of the resulting regions on the camera. I thus have a map proj_x, proj_y <-- cam_x, cam_y for scattered point pairs My original plan was to regularize this map using the Mathscript function griddata. This would work fine in MATLAB, as follows [pgridx, pgridy] = meshgrid(allprojxpts, allprojypts) fitcx = griddata (proj_x, proj_y, cam_x, pgridx, pgridy); fitcy = griddata (proj_x, proj_y, cam_y, pgridx, pgridy); and the reverse for the camera to projector mapping Unfortunately, this code causes Labview to run out of memory on the meshgrid step (the camera is 5 megapixels, which apparently is too much for labview to handle) I then started looking through openCV, and found the cvRemap function. Unfortunately, this function takes as its starting point a regularized pixel-pixel map like the one I was trying to generate above. However, it made me hope that functions for creating such a map might be available in openCV. I couldn't find it in the openCV 1.0 API (I am stuck with 1.0 for legacy reasons), but I was hoping it's there or that someone has an easy trick. So my question is one of the following 1) How can I interpolate from scattered points to a grid in openCV; (i.e., given z = f(x,y) for scattered values of x and y, how to fill an image with f(im_x, im_y) ? 2) How can I perform an image transform that maps image 1 to image 2, given that I know a scattered mapping of points in coordinate system 1 to coordinate system 2. This could be implemented either in Labview or OpenCV. Note: I am tagging this post delaunay, because that's one method of doing a scattered interpolation, but the better tag would be "scattered interpolation"

  • Is it possible to lightbox many images but only show one image to activate them?

    - by Obay
    Hi, I'm using Lightbox to display photos. So If I have two categories of photos, "work" and "vacation", I would do... <a href="images/image-1.jpg" rel="lightbox[work]">image #1</a> <a href="images/image-2.jpg" rel="lightbox[work]">image #2</a> <a href="images/image-3.jpg" rel="lightbox[work]">image #3</a> <a href="images/image-4.jpg" rel="lightbox[vacation]">image #4</a> <a href="images/image-5.jpg" rel="lightbox[vacation]">image #5</a> <a href="images/image-6.jpg" rel="lightbox[vacation]">image #6</a> This displays 6 images, and when I click one of them, it starts the Lightbox. However, I'd like to be able to display only two images initially (one for 'work', one for 'vacation'), but when one of them is clicked, it behaves like the first example, e.g. display all photos in that category through Lightbox. Is this possible? If so, how? Any help is very much appreciated! :) Thanks

  • Set the Image brightness and contrast using OpenGL ES.

    - by Viral
    hi friends, I want to set Image Brightness and contras of images that are in my photo library, I got the code from http://developer.apple.com/iphone/library/samplecode/GLImageProcessing/Introduction/Intro.html, but that will work on the EAGL layer i.e. all the effects are provided on image that is put initially not on the image that are selected from the photo library ,as this function will work on the view(EAGLview) and not on the image view. so how to change the brightness and contras of any images that are selected from the photo library?? if any one know this please let me know.. regards viral.

  • display image and script for a set period of time

    - by Ryan Max
    This is very similar to a question I asked the other day but my page code has become significantly more complicated and I need to revisit it. I've been using the following code: $('#myLink').click(function() { $('#myImg').attr('src', 'newImg.jpg'); setTimeout(function() { $('#myImg').attr('src', 'oldImg.jpg'); }, 15000); }); To replace an image for a set period of time (15 seconds) when the link is clicked, then after 15 seconds, revert to the original image. However now, I'd like to run a snippet of javascript as well when the link is clicked (in addition to replacing the image), and only when the link is clicked (it's related to the 15 second image) and then have the js code disappear as well after the 15 seconds...however I'm not sure how to have jquery send js code into the page...Basically I just want jQuery to "echo" this code onto the page underneath the 15 second while I am there, but I don't know how jquery formats this "echo". Does this question make sense?

  • Drupal image management

    - by vian
    Please suggest how should I approach these requirements. What ready-to-use solutions (modules) are best suited to achieve something like this: What I need is an image library that has searchable, tagged images that are already resized when we publish them. If the author searches the library and the image he needs isn’t there, he can upload one and have it added to the index. The important thing is that images in the library can be sorted into three categories: News images, top story images and feature images so that, over time, we don’t end up with hundreds of images crammed into one folder, thus making browsing a pain (and to prevent someone from something like: Searching for a keyword so they can find an image for the news, picking an image, and then seeing it’s 1600X. 1200). Also, I need something which will assemble thumbnail galleries easily. I don’t want to have to go to the image library, get a URL, go back, paste it in, etc. I should be able to pick, say, 8 images and say “create gallery”. How this objective is achieved is flexible, but I am looking for a shortcut to get around assembling screenshot galleries by hand.

  • iPhone: launch image for tab app?

    - by Karsten Silz
    I have a tab-based iPhone app where I want to increase the perceived start-up speed with a launch image. As defined by the iPhone HIG, the launch image is a screenshot of your app (called Default.png) that is displayed immediately and looks very similar to the app's first screen (e.g., the screenshot of an empty table when the app displays a table first). Now the problem with a tab-based app is that users can rearrange the order of tabs so that any of the tabs may be the first tab to show upon launch. I think I read somewhere that you can't change the Default.png programmatically in your app, but I couldn't find that in the HIG (and the "Clock" app seems to do exactly that - having one launch image per tab). So, how do provide a launch image for a tab-based app?

  • OutOfMemoryException with Image.Clone - Only on Windows 2003

    - by Jeff Rapp
    So here's my issue. I have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this: Dim bte() As Byte = System.Convert.FromBase64String(imgStr) Dim ms As New IO.MemoryStream(bte) Dim bmp As New System.Drawing.Bitmap(ms) Dim monoImage As Drawing.Bitmap = New Drawing.Bitmap(1200, 1800, Drawing.Imaging.PixelFormat.Format1bppIndexed) Dim rect As New Drawing.Rectangle(0, 0, 1200, 1800) monoImage = bmp.Clone(rect, Drawing.Imaging.PixelFormat.Format1bppIndexed) And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line. Any ideas as to what's happening, or perhaps a better solution to converting the image to B&W?

  • Flash AS3 blur or liquify part of an image with mouse

    - by hamlet
    Hi, I am very beginner in flash. I want to load an image, show a cursor over the image and on mousedown I want to blur that actual part of the image. (e.g you can blur your face on the image and then save the new image). I can delete parts of the image with white line, but I would like to blur it instead // LIVE JPEG ENCODER 0.3 // from bytearray.org import asfiles.encoding.JPEGEncoder; import flash.external.ExternalInterface; ExternalInterface.addCallback("flash_saveImage", inflash_saveImage); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleComplete); loader.load(new URLRequest(loaderInfo.parameters._filename)); //loader.load(new URLRequest("b.jpg")); var container_mc:MovieClip = new MovieClip;//create movieclip function handleComplete(e:Event):void { addChild(container_mc); var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData; var matrix:Matrix = new Matrix(); container_mc.graphics.clear(); container_mc.graphics.beginBitmapFill(bitmapData, matrix, false); //container_mc.graphics.beginFill(0xFFFFFF,0); container_mc.graphics.drawRect(0, 0, bitmapData.width, bitmapData.height); container_mc.graphics.endFill(); swapChildren(container_mc, pencil); container_mc.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing); container_mc.addEventListener(MouseEvent.MOUSE_UP, stopDrawing); container_mc.addEventListener(MouseEvent.MOUSE_MOVE, makeLine); } stage.addEventListener(MouseEvent.MOUSE_MOVE, moveCursor); Mouse.hide(); function moveCursor(event:MouseEvent):void { pencil.x = event.stageX; pencil.y = event.stageY; } function startDrawing(event:MouseEvent):void{ container_mc.graphics.lineStyle(20, 0xFFFFFF, 1); container_mc.graphics.moveTo(mouseX, mouseY); container_mc.addEventListener(MouseEvent.MOUSE_MOVE, makeLine); } function stopDrawing(event:MouseEvent):void{ container_mc.removeEventListener(MouseEvent.MOUSE_MOVE, makeLine); } function makeLine(event:MouseEvent):void{ container_mc.graphics.lineTo(mouseX, mouseY); } function inflash_saveImage ( ):void { var myURLLoader:URLLoader = new URLLoader(); var myBitmapSource:BitmapData = new BitmapData ( container_mc.width, container_mc.height ); // render the player as a bitmapdata myBitmapSource.draw ( container_mc ); // create the encoder with the appropriate quality var myEncoder:JPEGEncoder = new JPEGEncoder( 80 ); // generate a JPG binary stream to have a preview var myCapStream:ByteArray = myEncoder.encode ( myBitmapSource ); var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream"); var myRequest:URLRequest = new URLRequest ( "save.php" ); myRequest.requestHeaders.push (header); myRequest.method = URLRequestMethod.POST; myRequest.data = myCapStream; myURLLoader.load ( myRequest ); } Thanks, hamlet

  • .NET assembly cache / ngen / jit image warm-up and cool-down behavior

    - by Mike Jiang
    Hi, I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C#.NET DLL at the boot up time, to "warm up" the native image of that DLL. It works fine to speed up the loading time to 0.5 sec. However, it only worked for a while. About 30 min. later, it seems to "cool down" again. Is there any way to control the behavior of GAC or native image to be always "hot"? Is this exactly a image address rebasing problem? Thank you for your precious time. Sincerely, Mike

  • How to keep relative position of WPF elements on background image

    - by Masterfu
    Hi folks, I am new to WPF, so the answer to the following question might be obvious, however it isn't to me. I need to display an image where users can set markers on (As an example: You might want to mark a person's face on a photograph with a rectangle), however the markers need to keep their relative position when scaling the image. Currently I am doing this by using a Canvas and setting an ImageBrush as Background. This displays the image and I can add elements like a Label (as replacement for a rectangle) on top of the image. But when I set a label like this, it's position is absolute and so when the underlying picture is scaled (because the user drags the window larger) the Label stays at it's absolute position (say, 100,100) instead of moving to the new position that keeps it "in sync" with the underlying image. To cut the matter short: When I set a marker on a person's eye, it shouldn't be on the person's ear after scaling the window. Any suggestions on how to do that in WPF? Maybe Canvas is the wrong approach in the first place? I could keep a collection of markers in code and recalculate their position every time the window gets resized, but I hope there is a way to let WPF do that work for me :-) I am interested in hearing your opinions on this. Thanks

  • Median Filter a bi-level image with JAI

    - by Mark
    I'd like to apply a Median Filter to a bi-level image and output a bi-level image. The JAI median filter seems to output an RGB image, which I'm having trouble downconverting back to bi-level. Currently I can't even get the image back into gray color-space, my code looks like this: BufferedImage src; // contains a bi-level image ParameterBlock pb = new ParameterBlock(); pb.addSource(src); pb.add(MedianFilterDescriptor.MEDIAN_MASK_SQUARE); pb.add(3); RenderedOp result = JAI.create("MedianFilter", pb); ParameterBlock pb2 = new ParameterBlock(); pb2.addSource(result); pb2.add(new double[][]{{0.33, 0.34, 0.33, 0}}); RenderedOp grayResult = JAI.create("BandCombine", pb2); BufferedImage foo = grayResult.getAsBufferedImage(); This code hangs on the grayResult line and appears not to return. I assume that I'll eventually need to call the "Binarize" operation in JAI. Edit: Actually, the code appears to be stalling once I call getAsBufferedImage(), but returns nearly instantly when the second operation ("BandCombine") is removed. Is there a better way to keep the Median Filtering in the source color domain? If not, how do I downconvert back to binary?
