  • Java 2D Resize

    - by jon077
    I have some old Java 2D code I want to reuse, but was wondering, is this the best way to get the highest quality images? public static BufferedImage getScaled(BufferedImage imgSrc, Dimension dim) { // This code ensures that all the pixels in the image are loaded. Image scaled = imgSrc.getScaledInstance( dim.width, dim.height, Image.SCALE_SMOOTH); // This code ensures that all the pixels in the image are loaded. Image temp = new ImageIcon(scaled).getImage(); // Create the buffered image. BufferedImage bufferedImage = new BufferedImage(temp.getWidth(null), temp.getHeight(null), BufferedImage.TYPE_INT_RGB); // Copy image to buffered image. Graphics g = bufferedImage.createGraphics(); // Clear background and paint the image. g.setColor(Color.white); g.fillRect(0, 0, temp.getWidth(null),temp.getHeight(null)); g.drawImage(temp, 0, 0, null); g.dispose(); // j2d's image scaling quality is rather poor, especially when // scaling down an image to a much smaller size. We'll post filter // our images using a trick found at // http://blogs.cocoondev.org/mpo/archives/003584.html // to increase the perceived quality.... float origArea = imgSrc.getWidth() * imgSrc.getHeight(); float newArea = dim.width * dim.height; if (newArea <= (origArea / 2.)) { bufferedImage = blurImg(bufferedImage); } return bufferedImage; } public static BufferedImage blurImg(BufferedImage src) { // soften factor - increase to increase blur strength float softenFactor = 0.010f; // convolution kernel (blur) float[] softenArray = { 0, softenFactor, 0, softenFactor, 1-(softenFactor*4), softenFactor, 0, softenFactor, 0}; Kernel kernel = new Kernel(3, 3, softenArray); ConvolveOp cOp = new ConvolveOp(kernel, ConvolveOp.EDGE_NO_OP, null); return cOp.filter(src, null); }

  • how to convert byte array to image in java?

    - by nemade-vipin
    I am developing a Web application in Java. In that application, I have created webservices in Java. In that webservice, I have created one webmethod which returns the image list in base64 format. The return type of the method is Vector. In webservice tester I can see the SOAP response as xsi:type="xs:base64Binary". Then I called this webmethod in my application. I used the following code: SBTSWebService webService = null; List imageArray = null; List imageList = null; webService = new SBTSWebService(); imageArray = webService.getSBTSWebPort().getAddvertisementImage(); Iterator itr = imageArray.iterator(); while(itr.hasNext()) { String img = (String)itr.next(); byte[] bytearray = Base64.decode(img); BufferedImage imag=ImageIO.read(new ByteArrayInputStream(bytearray)); imageList.add(imag); } In this code I am receiving the error: java.lang.ClassCastException: [B cannot be cast to java.lang.String" on line String img = (String)itr.next(); Is there any mistake in my code? Or is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue? Note:- I already droped this question and I got the suggetion to try the following code Object next = iter.next(); System.out.println(next.getClass()) I tried this code and got the output as byte[] from webservice. but I am not able to convert this byte array to actual image. is there any other way to bring the image in actual format? Can you provide me the code or link through which I can resolve the above issue?

  • How to upload image to remote server in iphone?

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to upload a image which i am clicking with the help of the camera. I am trying the following code to upload the image to the remote server. -(void)searchAction:(UIImage*)theImage { UIDevice *dev = [UIDevice currentDevice]; NSString *uniqueId = dev.uniqueIdentifier; NSData * imageData = UIImagePNGRepresentation(theImage); NSString *postLength = [NSString stringWithFormat:@"%d",[imageData length]]; NSString *urlString = [@"http://www.amolconsultants.com/im.jsp?" stringByAppendingString:@"imagedata=iPhoneV0&mcid="]; urlString = [urlString stringByAppendingString:uniqueId]; urlString = [urlString stringByAppendingString:@"&lang=en_US.UTF-8"]; NSLog(@"The URL of the image is :- %@", urlString); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:imageData]; NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self]; if (conn == nil) { NSLog(@"Failed to create the connection"); } } But nothing is getting posted. Nothing comes in the console window also. I am calling this method in the action sheet. When the user clicks on the 1st button of the action sheet this method is called to post the image. Can anyone help me with this... Any code will be very helpful... Thanx in advance...

  • [FLEX] Images won't dynamically refresh

    - by Bridget
    I am writing a Flex application to receive xml from an httpservice. That works because I can populate a datagrid with the information. The xml sends image pathnames. A combobox sends a new HttpService call onChange. This repopulates the datagrid and puts new images in the folder that flex is accessing. I want to dynamically change the image without changing the pathname of the image. <mx:Canvas id="borderCanvas"><mx:Canvas id="dropCanvas"> <mx:Tile id="adTile"><mx:Image></mx:Image> </mx:Tile></mx:Canvas></mx:Canvas> This is my component. I assign my Image sources using this code: var i:Number = 0; while ( i <= dg_conads.rowCount){ var img:Image = new Image(); img.source = null; img.source = imageSource+i+".jpg"; adTile.addChild(img); i++; } My biggest problem is that the images are not refreshing. I get the same image even though I've prevented caching from the HTML wrapper and the ASP.Net website. The image automatically loads in the folder and refreshes in the folder but I can't get the image to refresh in the application. I've tried removeAllChildren(); delete(adTile.getChildAt(0)); and neither worked.

  • How can I put an image in my form?

    - by Santeron
    Hey guys, I'm having a problem. I want to put an image inside a form in Java and I don't know if I'm using a proper technique (found it somewhere in a web page). private void iconSelect() { String iconString = ""; if (typeCombobox.getSelectedIndex() == 0) { iconString = "LP_"; } else if (typeCombobox.getSelectedIndex() == 1) { iconString = "HP_"; } else if (typeCombobox.getSelectedIndex() == 2) { iconString = "BP_"; } else if (typeCombobox.getSelectedIndex() == 3) { iconString = "BS_"; } if (RB_Gain_Clean.isSelected()) { iconString = iconString + "Clean"; } else if (RB_Gain_dB.isSelected()) { iconString = iconString + "dB"; } ImageIcon icon = new ImageIcon("images/" + iconString + ".jpg"); Image img = icon.getImage(); if (iconGraphLabel.getWidth() > 0 && iconGraphLabel.getHeight() > 0) { img = img.getScaledInstance(iconGraphLabel.getWidth(), iconGraphLabel.getHeight(), java.awt.Image.SCALE_SMOOTH); } icon = new ImageIcon(img); iconGraphLabel.setIcon(icon); } So it actually shows the image and it is resizing but when I resize my form and then make it smaller again, the label doesn't seem to follow the resizing so it stays bigger than the window. Also, since I'm not very familiar with java's graphics, can anyone tell me how can I control a window resizing event so I redraw the picture? Right now the method is triggered by the combobox and the radiobuttons shown in the code. Thanks in advance!

  • Oracle Blob as img src in PHP page

    - by menkes
    I have a site that currently uses images on a file server. The images appear on a page where the user can drag and drop each as is needed. This is done with jQuery and the images are enclosed in a list. Each image is pretty standard: <img src='//network_path/image.png' height='80px'> Now however I need to reference images stored as a BLOB in an Oracle database (no choice on this, so not a merit discussion). I have no problem retrieving the BLOB and displaying on it's own using: $sql = "SELECT image FROM images WHERE image_id = 123"; $stid = oci_parse($conn, $sql); oci_execute($stid); $row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS); $img = $row['IMAGE']->load(); header("Content-type: image/jpeg"); print $img; But I need to [efficiently] get that image as the src attribute of the img tag. I tried imagecreatefromstring() but that just returns the image in the browser, ignoring the other html. I looked at data uri, but the IE8 size limit rules that out. So now I am kind of stuck. My searches keep coming up with using a src attribute that loads another page that contains the image. But I need the image itself to actually show on the page. (Note: I say image, meaning at least one image but as many as eight on a page). Any help would be greatly appreciated.

  • Convert partition to Virtual Disk image

    - by Rick
    I have a 250 GB HD with a XP partition. I partitioned the XP Box to 112 GB, since the max Virtual PC can load is 127 GB. I have a new motherboard and can't load into the partition, so I am using Windows 7. I have tried using WinImage to create the image but it creates an image of the whole disc (250 GB) and will not load on Virtual PC cause of the size limit. What would be best to convert to VHD correctly?

  • Best Practice for Images with Codeigniter : Generating Thumbs or Resizing on the Fly

    - by Steve K
    Hi all, I know there’s been a good deal written on thumbnail generation and the like with CI, but I wanted to explain what I’ve made and see what kind of best-practice advice I could find. Here’s my story… Currently, I have a site which allows users to upload collections of photos to projects they’ve created after first creating an account. Upon account creation, the site generates folders for the users in the following fashion for each of five pre-defined projects: /students/username/project_num/images/thumbs/ (This is to say that within a pre-created students folder, the username, project_num, images and thumbs folders are created recursively five times.) When a user uploads images to a project, I have a gallery controller which uploads the full images into the images folder for the project_num, and then creates a smaller thumbnail which maintains its ratio. So far so good. On the index page of the site, where these thumbnails and full images are displayed, I had a bit of a brain lapse, thinking I could simply output the full image while resizing it via css for a ‘medium-size’ image which would lead to the full-size image when clicked. (To be clear, the path is: Click on thumbnail— Load scaled full-size (medium-size) image via ajax into a display area above thumbs— Click on medium-sized image— Load full size image via lightbox, or something of that nature.) I have everything working to this point, except, as one might imagine, resizing the full-sized images with css doesn’t maintain aspect ratio for the thumbs, which means I need to find the best way to resize these. In thinking about it, I figured I had two options: I could resize the image on the fly when the user clicks a thumbnail to load the medium-sized image via ajax. (I have a method ‘get_image($url)’ in my gallery controller which simply loads a view with an image tag and the image source passed to it, etc.) I thought perhaps I could send it first to my gallery model, resize it there on the fly, and send it on to the view. The problem I’m having is that resizing it on the fly and echoing it out gives me the raw image data (I apologize, I don’t know that’s the right term). I’ve tried using data_uris to format the raw data into something echoable, but with no success. Is this method possible? The second option I considered was to generate a second medium-sized thumbnail when the user uploads the image with maintain_ratio set to true. This method is slightly less ideal, given that when providing a way for the user to delete their projects, I’ll need to scan for an additional set of images to delete. Not a huge deal, definitely, but something I figured could be avoided by generating the medium-sized image on the fly. I hope I’ve been clear in my explanations, if long-winded! I’m very curious to see what suggestions folks have about the best way to handle this. Much thanks for reading, and any suggestions are much-appreciated! Steve K.

  • Image Preview in ASP.NET MVC

    - by imran_ku07
      Introduction :         Previewing an image is a great way to improve the UI of your site. Also it is always best to check the file type, size and see a preview before submitting the whole form. There are some ways to do this using simple JavaScript but not work in all browsers (like FF3).In this Article I will show you how do this using ASP.NET MVC application. You also see how this will work in case of nested form.   Description :          Create a new ASP.NET MVC project and then add a file upload and image control into your View. <form id="form1" method="post" action="NerdDinner/ImagePreview/AjaxSubmit">            <table>                <tr>                    <td>                        <input type="file" name="imageLoad1" id="imageLoad1"  onchange="ChangeImage(this,'#imgThumbnail')" />                    </td>                </tr>                <tr>                    <td align="center">                        <img src="images/TempImage.gif" id="imgThumbnail" height="200px" width="200px">                     </td>                </tr>            </table>        </form>           Note that here NerdDinner is refers to the virtual directory name, ImagePreview is the Controller and ImageLoad is the action name which you will see shortly          I will use the most popular jQuery form plug-in, that turns a form into an AJAX form with very little code. Therefore you must get these from Jquery site and then add these files into your page.          <script src="NerdDinner/Scripts/jquery-1.3.2.js" type="text/javascript"></script>        <script src="NerdDinner/Scripts/jquery.form.js" type="text/javascript"></script>            Then add the javascript function. <script type="text/javascript">function ChangeImage(fileId,imageId){ $("#form1").ajaxSubmit({success: function(responseText){ var d=new Date(); $(imageId)[0].src="NerdDinner/ImagePreview/ImageLoad?a="+d.getTime(); } });}</script>             This function simply submit the form named form1 asynchronously to ImagePreviewController's method AjaxSubmit and after successfully receiving the response, it will set the image src property to the action method ImageLoad. Here I am also adding querystring, preventing the browser to serve the cached image.           Now I will create a new Controller named ImagePreviewController. public class ImagePreviewController : Controller { [AcceptVerbs(HttpVerbs.Post)] public ActionResult AjaxSubmit(int? id) { Session["ContentLength"] = Request.Files[0].ContentLength; Session["ContentType"] = Request.Files[0].ContentType; byte[] b = new byte[Request.Files[0].ContentLength]; Request.Files[0].InputStream.Read(b, 0, Request.Files[0].ContentLength); Session["ContentStream"] = b; return Content( Request.Files[0].ContentType+";"+ Request.Files[0].ContentLength ); } public ActionResult ImageLoad(int? id) { byte[] b = (byte[])Session["ContentStream"]; int length = (int)Session["ContentLength"]; string type = (string)Session["ContentType"]; Response.Buffer = true; Response.Charset = ""; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = type; Response.BinaryWrite(b); Response.Flush(); Session["ContentLength"] = null; Session["ContentType"] = null; Session["ContentStream"] = null; Response.End(); return Content(""); } }             The AjaxSubmit action method will save the image in Session and return content type and content length in response. ImageLoad action method will return the contents of image in response.Then clear these Sessions.           Just run your application and see the effect.   Checking Size and Content Type of File:          You may notice that AjaxSubmit action method is returning both content type and content length. You can check both properties before submitting your complete form.     $(myform).ajaxSubmit({success: function(responseText)            {                                var contentType=responseText.substring(0,responseText.indexOf(';'));                var contentLength=responseText.substring(responseText.indexOf(';')+1);                // Here you can do your validation                var d=new Date();                $(imageId)[0].src="http://weblogs.asp.net/MoneypingAPP/ImagePreview/ImageLoad?a="+d.getTime();            }        });  Handling Nested Form Case:          The above code will work if you have only one form. But this is not the case always.You may have a form control which wraps all the controls and you do not want to submit the whole form, just for getting a preview effect.           In this case you need to create a dynamic form control using JavaScript, and then add file upload control to this form and submit the form asynchronously  function ChangeImage(fileId,imageId)         {            var myform=document.createElement("form");                    myform.action="NerdDinner/ImagePreview/AjaxSubmit";            myform.enctype="multipart/form-data";            myform.method="post";            var imageLoad=document.getElementById(fileId).cloneNode(true);            myform.appendChild(imageLoad);            document.body.appendChild(myform);            $(myform).ajaxSubmit({success: function(responseText)                {                                    var contentType=responseText.substring(0,responseText.indexOf(';'));                    var contentLength=responseText.substring(responseText.indexOf(';')+1);                    var d=new Date();                    $(imageId)[0].src="http://weblogs.asp.net/MoneypingAPP/ImagePreview/ImageLoad?a="+d.getTime();                    document.body.removeChild(myform);                }            });        }            You also need append the child in order to send request and remove them after receiving response.

  • multi-dimension array problem in RGSS (RPG Maker XP)

    - by AzDesign
    This is my first day code script in RMXP. I read tutorials, ruby references, etc and I found myself stuck on a weird problem, here is the scenario: I made a custom script to display layered images Create the class, create an instance variable to hold the array, create a simple method to add an element into it, done The draw method (skipped the rest of the code to this part): def draw image = [] index = 0 for i in [email protected] if image.size > 0 index = image.size end image[index] = Sprite.new image[index].bitmap = RPG::Cache.picture(@components[i][0] + '.png') image[index].x = @x + @components[i][1] image[index].y = @y + @components[i][2] image[index].z = @z + @components[i][3] @test =+ 1 end end Create an event that does these script > $layerz = Layerz.new $layerz.configuration[0] = ['root',0,0,1] > $layerz.configuration[1] = ['bark',0,10,2] > $layerz.configuration[2] = ['branch',0,30,3] > $layerz.configuration[3] = ['leaves',0,60,4] $layerz.draw Run, trigger the event and the result : ERROR! Undefined method`[]' for nil:NilClass pointing at this line on draw method : image[index].bitmap = RPG::Cache.picture(@components[i][0] + '.png') THEN, I changed the method like these just for testing: def draw image = [] index = 0 for i in [email protected] if image.size > 0 index = image.size end image[index] = Sprite.new image[index].bitmap = RPG::Cache.picture(@components[0][0] + '.png') image[index].x = @x + @components[0][1] image[index].y = @y + @components[0][2] image[index].z = @z + @components[0][3] @test =+ 1 end I changed the @components[i][0] to @components[0][0] and IT WORKS, but only the root as it not iterates to the next array index Im stuck here, see : > in single level array, @components[0] and @components[i] has no problem > in multi-dimension array, @components[0][0] has no problem BUT > in multi-dimension array, @components[i][0] produce the error as above > mentioned. any suggestion to fix the error ? Or did I wrote something wrong ?

  • Bizarre image loading problem from apache2

    - by NateDSaint
    Users have complained a few times about seeing a bizarre set of pink or green stripes on our webpage. At first I thought there were a rash of video card outages, but then someone sent me a screenshot from their browser (IE8). I later saw the same thing, but with slightly different colors on Chrome. Users have experienced this on their iPads and iPhones (iOS Safari). Because I've optimized the site to cache images, the bad image stays around until you clear your cache, so once you do, it resolves itself. My assumption is that the transmission of the image is being cut off mid-stream and then staying that way, but I can't for the life of me figure out why. Here's what I've checked: Header length is being sent, and transmission looks okay (wget sample below): wget http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg --2012-04-05 08:46:00-- http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg Resolving www.superiorlivestock.com (www.superiorlivestock.com)...

  • convert image to spritesheet of tiles for isometric map?

    - by Paul
    is there a way to convert an isometric image (like the first image) to a spritesheet (like the second image), in order to place each image on the isometric map with the code? The map looks like the first image, but some buildings are bigger than just one tile, so I need several squares (let's say the first image is a building, made of multiple tiles with different colors), and each square is placed with an offset of 64x32. The building is created in Blender and I save the image with the isometric perspective. But I have to split each square from this image in order to have the spritesheet, maybe there is smarter way, or a java software that would make the conversion for me?

  • Ubuntu 14.04 has a bunch of old kernel directories

    - by NoBugs
    I saw in Disk Usage Analyzer I have 3.13.0-xx for 8 minor versions of the kernel in /lib/modules. Each is around 200MB. I remember having to go through in Synaptic and remove those old Linux versions before, but hasn't this bug been fixed? Is it just paranoid default setting, that perhaps all of the last half dozen kernels might become unbootable, so it keeps each old one around? Or do I have some developer setting enabled by accident that causes this?

  • Why does linux-image-virtual depend on a generic kernel now?

    - by ændrük
    The linux-image-virtual metapackage has historically provided a kernel that is specifically designed for use in virtual machines: Ubuntu 8.04: linux-image-2.6.24-32-virtual Ubuntu 10.04: linux-image-2.6.32-44-virtual Ubuntu 11.10: linux-image-3.0.0-26-virtual Ubuntu 12.04: linux-image-3.2.0-32-virtual Apparently, this has now changed: Ubuntu 12.10: linux-image-3.5.0-17-generic What's the explanation? Is this still the correct kernel to use in a virtual machine?

  • How to detect a touch on transparent area of an image in a (libgdx) stage?

    - by Usman
    Can some one please help to detect a touch on an image which I am using as an actor in a stage. The image is actually a long diagnol brush which has plenty of transparent area. The problem is when I touche the transparent area of the brush image it is also triggering the clicklistener of the image. I need the click listener should only be called when the finger actually touched the visible image not the area which is empty. I am using libgdx-0.9.4 libraries. Here is my simple piece of code. import com.badlogic.gdx.scenes.scene2d.ui.Image; import com.badlogic.gdx.scenes.scene2d.ui.ClickListener; Image brushImg = new Image(ImageCache.getTexture("brush")); brushImg.width = mStage.width()*0.75f; brushImg.height = mStage.height()*0.75f; brushImg.setClickListener(new ClickListener() { @Override public void click(Actor actor, float x, float y) { SoundFactory.play("brush"); }

  • Linking with an image: Background vs <img>

    What is considered best practice (semantically) when using text with an image to link to an internal page or category? Option 1 <nav> <a href="/kittens"> <img src="kittens.png" /> <span>Kittens</span> </a> <a href="/puppies"> <img src="puppies.png" /> <span>Puppies</span> </a> </nav> Option 2 <nav> <a href="/kittens" class="kittens">Kittens</a> <a href="/puppies" class="puppies"><span>Puppies</a> </nav> where the CSS is defined: a.kittens { background-image:url("kittens.png"); width:40px; height:60px; } a.puppies { background-image:url("puppies.png"); width:40px; height:60px; } Should I use a styled background for the link, or an <img> inside the anchor element?

  • Create a system image in Windows 8

    - by Greg Low
    One of the things that I've just come to accept is that the designers of Windows 8 and I think very differently.It'll take a long time to convince me that shutting down the computer is a "setting". Even after using Windows 8 for quite a while now, I still find that I struggle nearly every day, just trying to do things that I previously knew how to do. That's just not a good thing.Today I decided to create a system image as I hadn't made one lately. I started in Control Panel looking for Backup options. That yielded nothing except programs that wanted to "Save backup copies of my files with file history". I thought "oh well, let's just try the new search options". I hit the Windows key and typed "Backup". No, nothing came up there either.I searched again all over the Control Panel options to no avail.So it was time to hit Google again. Once again, clearly lots of people used to know how to do this and have been trying to work out where this option went.The first trick is that there are a bunch of Control Panel options that don't appear in the Control Panel. In the address bar at the top, if you click on Control Panel, you'll find there is an option that says "All Control Panel Options". That is curious given that's where I thought I was when I opened Control Panel. No hint is given on that screen that there are a bunch of hidden options. None the less, I then checked out "all" the options.The option that you need to create a system image in Windows 8 turns out to be the "Windows 7 File Recovery" option that appears in this extended list. Why does it say "Windows 7" when it's for "Windows 8" as well and I'm running "Windows 8"? Why do I have to choose an option that says "File Recovery" to create a system image backup?<sigh>But at least I've recorded it here for the next time I forget where to find it.

  • Scale an image with unscalable parts

    - by Uko
    Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

  • What partition PlayOnLinux and Wine software has to be installed to?

    - by user211076
    please tell I'm using Ubuntu 12.04 and if I have already created ext4 ./ (partition) and on the same volume I have ./home so if I create a separate partition ./home will the software that I install for example from Ubuntu Download Center will automatically go to ./home (partition) or still ./ (root) because I'm using PlayOnLinux and Wine and all its software only installs to ./home (file system disk) where emulated copy of Windows Xp installed also and it's a lack of space.
