  • Clean install vs disk image

    - by Thanos
    Once a year I am making a clean install on windows, in order to keep my system fast. After posting a question on making a bootable windows usb with exe programs where I was adviced to make a disk image, a new question rose. What is the difference in making a disk image and performing a clean install on windows? Which is better in terms of speed, general performance, value for time and transfering between different computers?

  • Acordex Image viewer throws out of memory exception in CITRIX environment

    - by neha
    We have a .net 2.0 application. In the .aspx page we are calling the java applet using . This applet is calling the Acordex Image viewer. In the production environment users are facing "out of memory" or "insufficient memory" issues when users try to open the image or magnify an image in Acordex viewer. Strangely when the users logout and login again they are able to see the same image without any errors. The website is hosted in a CITRIX environment. We have access to this environment but we are not able to reproduce this issue on the test servers or the local machines. We dont know what is causing this issue. What should we do to troubleshoot the issue? Do we have to increase the memory allotted to the users in CITRIX? The RAM is around 4 gb. Number of simultaneous users - 10-13. image size is max 2 mb Following is the code used to call Acordex image viewer:

  • Codeigniter image manipulation class rotates image during resize

    - by someoneinomaha
    I'm using Codeigniter's image manipulation library to re-size an uploaded image to three sizes, small, normal and large. The re-sizing is working great. However, if I'm resizing a vertical image, the library is rotating the image so it's horizontal. These are the config settings I have in place: $this->resize_config['image_library'] = 'gd2'; $this->resize_config['source_image'] = $this->file_data['full_path']; $this->resize_config['maintain_ratio'] = TRUE; // These change based on the type (small, normal, large) $this->resize_config['new_image'] = './uploads/large/'.$this->new_file_name.'.jpg'; $this->resize_config['width'] = 432; $this->resize_config['height'] = 288; I'm not setting the master_dim property because the default it set to auto, which is what I want. My assumption is that the library would take a vertical image, see that the height is greater than the width and translate the height/width config appropriately so the image remains vertical. What is happening (apparently) is that the library is rotating the image when it is vertical and sizing it per the configuration. This is the code in place I have to do the actual re-sizing: log_message('debug', 'attempting '.$size.' photo resize'); $this->CI->load->library('image_lib'); $this->CI->image_lib->initialize($this->resize_config); if ($this->CI->image_lib->resize()) { $return_value = TRUE; log_message('debug', $size.' photo resize successful'); } else { $this->errors[] = $this->CI->image_lib->display_errors(); log_message('debug', $size.' photo resize failed'); } $this->CI->image_lib->clear(); return $return_value;

  • Sanity check on this idea for an Image Viewer in a web app

    - by Charlie Flowers
    I have an approach in mind for an image viewer in a web app, and want to get a sanity check and any thoughts you stackoverflowers might have. Here's the whirlwind nutshell summary: I'm working on an ASP.NET MVC application that will run in my company's retail stores. Even though it is a web application, we own the store machines and have control over them. We have a "windows agent" running on the store machine which we can talk to via http post (it is a WCF service, and our web app has permission to talk to it from the browser). One of the web pages needs to be an "image viewer" page with some common things like Rotate & Zoom. Now, there are some WebForms controls that offer Rotate and Zoom. However, they take up server resources and generate a good bit of traffic between the server and the browser. For example, the Rotate function would cause an ajax call to the server, which would then generate a new image written to a .NET Canvas object, which would then be written to a file on the server, which would then be returned from the ajax call and refreshed inside the browser. Normally, that's a pretty good way of doing things. But in our case, we have code running on the store machine that we can communicate with. This leads me to consider the following approach: When the user asks to view an image, we tell our "windows agent" to download it from our image server to the store machine. We then redirect our browser to our image viewer page, which will pull the image from the local file we just wrote to the store machine. When the user clicks "Rotate", we cause JavaScript code in the browser to call our "windows agent" software, asking it to perform the "Rotate" function. The "windows agent" does the rotation using the same kind of imaging control that would formerly have been used on the server, but it does so now on the store machine. Javascript in the browser then refreshes the image on the page to show the newly rotated image. Zoom and similar features would be implemented the same way. This seems to be much more efficient, scalable, and responsive for the end-users. However, I've never heard of anything like it being done, mostly because it's rare to have this combination of a web app plus a "windows agent" on the client machine. What do you think? Feasible? Reasonable? Any pitfalls I overlooked or improvements / suggestions you can see? Has anyone done anything like this who would like to offer the wisdom of experience? Thanks!

  • How do I create an OpenCV image from a PIL image?

    - by scrible
    I want to do some image processing with OpenCV (in Python), but I have to start with a PIL Image object, so I can't use the cvLoadImage() call, since that takes a filename. This recipe (adapted from http://opencv.willowgarage.com/wiki/PythonInterface) does not work because cvSetData complains argument 2 of type 'void *' . Any ideas? from opencv.cv import * from PIL import Image pi = Image.open('foo.png') # PIL image ci = cvCreateImage(pi.size, IPL_DEPTH_8U, 1) # OpenCV image data = pi.tostring() cvSetData(ci, data, len(data)) I think the last argument to the cvSetData is wrong too, but I am not sure what it should be.

  • "A generic error occurred in GDI+" error while showing uploaded images

    - by Prasad
    i am using the following code to show the image that has been saved in my database from my asp.net mvc(C#) application:. public ActionResult GetSiteHeaderLogo() { SiteHeader _siteHeader = new SiteHeader(); Image imgImage = null; long userId = Utility.GetUserIdFromSession(); if (userId > 0) { _siteHeader = this.siteBLL.GetSiteHeaderLogo(userId); if (_siteHeader.Logo != null && _siteHeader.Logo.Length > 0) { byte[] _imageBytes = _siteHeader.Logo; if (_imageBytes != null) { using (System.IO.MemoryStream imageStream = new System.IO.MemoryStream(_imageBytes)) { imgImage = Image.FromStream(imageStream); } } string sFileExtension = _siteHeader.FileName.Substring(_siteHeader.FileName.IndexOf('.') + 1, _siteHeader.FileName.Length - (_siteHeader.FileName.IndexOf('.') + 1)); Response.ContentType = Utility.GetContentTypeByExtension(sFileExtension.ToLower()); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.BufferOutput = false; if (imgImage != null) { ImageFormat _imageFormat = Utility.GetImageFormat(sFileExtension.ToLower()); imgImage.Save(Response.OutputStream, _imageFormat); imgImage.Dispose(); } } } return new EmptyResult(); } It works fine when i upload original image. But when i upload any downloaded images, it throws the following error: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. at System.Drawing.Image.Save(Stream stream, ImageCodecInfo encoder, EncoderParameters encoderParams) at System.Drawing.Image.Save(Stream stream, ImageFormat format) For. Ex: When i upload the original image, it shows as logo in my site and i downloaded that logo from the site and when i re-upload the same downloaded image, it throws the above error. It seems very weird to me and not able to find why its happening. Any ideas on this?

  • Vertical Aligned Text and Image in list

    - by Wayne
    Is there a way of vertical aligning text and an image in a list? e.g. <li>Some text here <img src="image.jpg" alt="" /></li> The text doesn't align in the middle of the side of the image, it appears at the bottom then the image is next to it. I need the text to be in the center point between the image on the side. What's the best way of doing it? I know having a image inside a list isn't valid HTML (AFAIK). Thanks :)

  • JFrame does not refresh after deleting an image

    - by dajackal
    Hi! I'm working for the first time with images in a JFrame, and I have some problems. I succeeded in putting an image on my JFrame, and now i want after 2 seconds to remove my image from the JFrame. But after 2 seconds, the image does not disappear, unless I resize the frame or i minimize and after that maximize the frame. Help me if you can. Thanks. Here is the code: File f = new File("2.jpg"); System.out.println("Picture " + f.getAbsolutePath()); BufferedImage image = ImageIO.read(f); MyBufferedImage img = new MyBufferedImage(image); img.resize(400, 300); img.setSize(400, 300); img.setLocation(50, 50); getContentPane().add(img); this.setSize(600, 400); this.setLocationRelativeTo(null); this.setVisible(true); Thread.sleep(2000); System.out.println("2 seconds over"); getContentPane().remove(img); Here is the MyBufferedImage class: public class MyBufferedImage extends JComponent{ private BufferedImage image; private int nPaint; private int avgTime; private long previousSecondsTime; public MyBufferedImage(BufferedImage b) { super(); this.image = b; this.nPaint = 0; this.avgTime = 0; this.previousSecondsTime = System.currentTimeMillis(); } @Override public void paintComponent(Graphics g) { Graphics2D g2D = (Graphics2D) g; g2D.setColor(Color.BLACK); g2D.fillRect(0, 0, this.getWidth(), this.getHeight()); long currentTimeA = System.currentTimeMillis(); //g2D.drawImage(this.image, 320, 0, 0, 240, 0, 0, 640, 480, null); g2D.drawImage(image, 0,0, null); long currentTimeB = System.currentTimeMillis(); this.avgTime += currentTimeB - currentTimeA; this.nPaint++; if (currentTimeB - this.previousSecondsTime > 1000) { System.out.format("Drawn FPS: %d\n", nPaint++); System.out.format("Average time of drawings in the last sec.: %.1f ms\n", (double) this.avgTime / this.nPaint++); this.previousSecondsTime = currentTimeB; this.avgTime = 0; this.nPaint = 0; } } }

  • Android : Stop image scaling down

    - by John Smith
    Hi, I'm trying to draw an image in a view but having problems trying to maintain the scale of the original image. Basically, I have a small view and I would like to show part of the image in the view. The intention then is to perform a translation on the image so that a different part appears in the view. No matter what I try, either the image is down-scaled automatically to fit the view or the whole image is viewable. I've tried playing about with the settings on BitmapDrawable, ImageView and Layout to no avail. Anyone know a good way to achieve this?

  • How to test whether an image is already in cache? [migrated]

    - by Evik James
    I am developing a web site that has a lot of large, high-quality images on the home page. On the home page, there is an image carousel that pulls ten high quality images from a database. The images can be 1 meg each. The carousel images aren't my problem (right now), but it has something to do with it. The problem I am trying to address right now is that I use a high quality background image that I want to continue using, it's about 180k. If I have the background in cache on the home page, I want to use it. If not, then I don't want to use it on the home page. I'll load it from a different page. When the user returns to the home page, and the background image is in cache, I want to use it. Can I test whether an image is already in cache and if so, dynamically load or NOT load based on that? You can see the home page here: http://flyingpiston2012-com.securec37.ezhostingserver.com/

  • How to boot Windows XP using the image file(not the extracted image file)

    - by Nrew
    Is it possible to boot from an iso image file itself. Because when you burn it, it gets extracted. Because in linux you can just place the .iso file in a removable media and boot from it without extracting. Is it possible to make something like that in windows? What I'm saying is related to this: http://wintoflash.com/forum/viewtopic.php?f=5&t=312 Something like creating a flash drive which has the ability to install multiple os. They have something like this in pendrivelinux but I can't find it anymore. But that boot manager can only install linux. And other live cd's used in cleaning the system. That's why I'm asking if its possible to make a custom windows xp or windows 7 installer so that the image file alone can boot.

  • How to transfer Windows Vista disk image to new machine

    - by Mike Hobbs
    I'm trying to upgrade a user's machine to some better hardware. I know of Easy Transfer, but I'd rather not have to reinstall all the programs that are already present. (Some of which are no longer available, anyway). Instead, I'm trying to transfer the entire disk image from one machine to the other, but I ran into issues. If I copy the partition image over to the new machine using Clonezilla, I get errors on boot saying that I need to insert the Vista install disk and run repair. I do that, but it then says that it is unable to repair whatever it is that's broken. Next, I tried to sysprep the old machine before creating the image, but sysprep fails saying that it encountered some sort of system error. Should it be possible to sysprep any arbitrary machine, or does it only work on a relatively clean install? Could it be a missing driver that is tripping me up? The new machine is a fairly stock desktop that shouldn't need any special drivers beyond what's already present in standard Vista. Are there any foolproof methods for doing this sort of thing?

  • Looking for "bitmap-vector" image editor

    - by Borek
    I used to use PhotoImpact which is no longer developed so I'm looking for a replacement. What made PhotoImpact great to me was the ability to work in both bitmap and vector modes. What I mean by that: I could have an image or screenshot and easily add arrows, text captions or shapes to it. These shapes were vector objects so I could come back to them later and amend their properties easily. Software I know of: Paint.NET is purely bitmap so please don't recommend it - layers are not enough for my needs Drawing tools in MS Office work pretty much the way I'd like - you can paste an image and then add vector objects on top of it. It just doesn't feel right to have the full-fidelity original images stored as .docx or .pptx (I don't fully trust Word/Powerpoint that they don't compress the image) I'm not sure about GIMP but if it's just "better Paint.NET" (i.e., layers but no vector objects) I'm not interested Photoshop is out of question purely because of its price tag Corel killed PhotoImpact because they already had a competing product (Paint Shop Pro) but AFAIK it lacks vector features. Any tips for PhotoImpact alternatives would be very welcome.

  • What algorithms would suit image colour summarization? [on hold]

    - by codecowboy
    I would like to analyse a set of hundreds of thousands of product images (clothing, electronic goods etc) and retrieve the dominant colours in each. I'm only interested in the top 3 or 4 colours. The aim is to achieve a degree of certainty that x image is mostly red or image y is mostly orange and blue. The images are likely to be colour jpegs of reasonable quality and approximately 100kb in size. I would like to use C# and the solution should run on a Linux server, preferably using open source libraries. What image processing algorithms or techniques might help me achieve this?

  • How do I un-zoom compiz?

    - by Ken
    I'm using a keyboard I'm not used to, and I hit Super_L instead of Alt_L when I middle-mouse-dragged across the screen. On this Ubuntu 10.04 with Compiz, apparently, this zooms the screen to the area that I dragged across. Now I'm stuck. I can super-middle-drag across a bigger area, but apparently I can't quite hit all of the corners exactly because the screen still moves a bit when I move the mouse around. How do I undo this zoom effect completely? This looks like "EZoom", which says that super-"1" (default keybinding, anyway) should reset it, but that doesn't seem to work here. Close...

  • How do I convert a partially transparent image into polygons?

    - by user82779
    I'm using GLEE2D, a level editor allowing me to import images, scale them, rotate them, and position them onto layers and export the data into XML format. However, it does not tell me objects' boundaries. I can calculate them, but only given the original image's polygons. How do I get polygons of objects in a transparent image? An example object (I outlined it): How would I turn the object, knowing the scaled size of the image, into polygons? Is there an algorithm for this? I'll use OpenGL to draw them.

  • jQuery selector issue finding image with usemap attribute

    I have an image map in my page: <div id="books"> <img src="images/books.png" width="330" height="298" border="0" \ usemap="#map_books" /> <map name="map_books" id="map_books" alt="books"> <area shape="poly" coords="17,73,81,288,210,248,254,264, ..." \ href="/about" alt="books" /> </map> </div> I have a function that tries to find the image in the document using this map: function(elemId) { // elemId = "#map_books" if ($(elemId).attr("tagName") == "MAP") { // find image using this map var selector = "img [usemap=\\" + elemId + "]"; var img = $(selector); if (img.length == 0) { console.log("Could not find image using " + selector); } } It fails to find the image. Could not find image using img [usemap=\#map_books] I've escaped the elemId because it starts with a hash and tried variations of selectors. $("img [usemap$=" + elemId.substring(1) + "]") $("img").find("[usemap=\\" + elemId + "]") Neither find the image. Any ideas?

  • C# program that generates html pages - limit image dimensions on page

    - by Professor Mustard
    I have a C# program that generates a large number of html pages, based on various bits of data and images that I have stored on the file system. The html itself works just fine, but the images can vary greatly in their dimensions. I need a way to ensure that a given image won't exceed a certain size on the page. The simplest way to accomplish this would be through the html itself... if there was some kind of "maxwidth" or "maxheight" property I could set in the html, or maybe a way to force the image to fit inside a table cell (if I used something like this, I'd have to be sure that the non-offending dimension would automatically scale with the one that's being reduced). The problem is, I don't know much about this "fine tuning" kind of stuff in html, and it seems to be a tough thing to Google around for (most of the solutions involve some sort of html specialization; I'm just using plain html). Alternatively, I could determine the width and height of each image at runtime by examining the image in C#, and then setting width/height values in the html if the image's dimensions exceed a certain value. The problem here is that is seems incredibly inefficient to load an entire image into memory, just to get its dimensions. I would need a way to "peek" at an image and just get its size (it could be bmp, jpg, gif or png). Any recommendations for either approach would be greatly appreciated.
