  • CSS: series of floated elements without wrapping but rather scrolling horizontally

    - by tybro0103
    I'm working on a album viewer. At the top I want a horizontal container of all the image thumbnails. Right now all the thumbnails are wrapped in a div with float:left. I'm trying to figure out how to keep these thumbnails from wrapping to the next line when there are too many, but rather stay all in one horizontal row and use the scrollbar. Here's my code: (I don't want to use tables) <style type="text/css"> div { overflow:hidden; } #frame { width:600px; padding:8px; border:1px solid black; } #thumbnails_container { height:75px; border:1px solid black; padding:4px; overflow-x:scroll; } .thumbnail { border:1px solid black; margin-right:4px; width:100px; height:75px; float:left; } .thumbnail img { width:100px; height:75px; } #current_image_container img { width:600px; } </style> <div id="frame"> <div id="thumbnails_container"> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/glry-pixie-bob-kittens.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-KitJan08-1.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-KitJan08-3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/PB-Jan08.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/gallery3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/images/gallery4.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/Gallery-Pics/kitten3.jpg" alt="foo" /></div> <div class="thumbnail"><img src="http://www.blueridgexotics.com/Gallery-Pics/kitten1.jpg" alt="foo" /></div> </div> <div id="current_image_container"> <img src="http://www.whitetailrun.com/Pixiebobs/PBkittenpics/shani-kits/Cats0031a.jpg" alt="foo" /> </div> </div>

  • Is there a way to increase how much is cached for thumbnail views of pictures?

    - by JimDel
    Is there a way to increase how much is cached for thumbnail views of pictures? If I'm looking through a folder of .png files for example, with "medium" set as the view size. The screen will eventually fill all the thumbnails with the appropriate pictures. But as I scroll down it takes a while for the pictures to fill in again. I would like a way for "off screen" pictures to fill in before I get the that section of the screen. Is there a way to do this? Thanks

  • Can I manually add a thumbnail web page to the Chrome homepage?

    - by andygrunt
    Is there a way to manually add a web page to the 8 thumbnails that appear when you open Chrome? I want to add Google Maps for easy access. The Google front page already shows up so I presume the Google Maps page never will as it's a subset of Google (i.e. I get to it via the main Google front page). I know I can add a shortcut to the toolbar but would rather add it as a thumbnail. And while I'm here, is it possible to increase the number of thumbnails that appear? I'm running the release/stable version of Chrome in Windows XP.

  • Tool to create unscaled call-out from a thumbnail image?

    - by Mal Ross
    I'm creating an online tutorial for some software and need to include screenshots. In particular, I want to highlight the position and appearance of a given control in a large screen. Given that I haven't got the space to show the screen at full resolution (at least, not alongside the tutorial text), I figured I would use a kind of call-out from a thumbnail. Here's my poor first effort, made in Paint.NET: Given how long this took me to craft, I'd really like to find a tool to speed things up (and make them look a little more professional!). Preferably a free one, too - or one that has a downloadable trial. The exact style it produces isn't that important, provided it achieves the desired effect. Can anyone help me out? Thanks, Mal. P.S. I'm using Windows Vista.

  • How can I resize a set of sprite images?

    - by Tyler J Fisher
    Hey StackExchange GameDev community, I'm attempting to resize series of sprites upon instantiation of the class they're located in. I've attempted to use the following code to resize the images, however my attempts have been unsuccessful. I have been unable to write an implementation that is even compilable, so no error codes yet. wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); I've heard that Graphics2D is the best option. Any suggestions? I think I'm probably best off loading the images into a Java project, resizing the images then outputting them to a new directory so as not to have to resize each sprite upon class instantiation. What do you think? Photoshopping each individual sprite is out of the question, unless I used a macro. Code: package game; //Import import java.awt.Image; import javax.swing.ImageIcon; public class Mario extends Human { Image wLeft = new ImageIcon("sprites\\mario\\wLeft.PNG").getImage(); //Constructor public Mario(){ super("Mario", 50); wLeft = wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); }

  • How to Extract the images from the doc file without Having Microsoft office ?

    Originally posted on: http://geekswithblogs.net/anirugu/archive/2013/06/29/how-to-extract-the-images-from-the-doc-file-without.aspxMany time we got the doc file who have some images. We need to try to extract them in Microsoft word which come with Windows 7 (not Microsoft office word). Looking to this article http://www.techrepublic.com/blog/itdojo/save-images-in-microsoft-word-documents-as-separate-files/135 This article is only useful when you have Microsoft word installed. Now if I don’t have Microsoft office then what ? No problem, here is a trick. when you open the doc file in Word  then select the image and right click on image and choose cut. open the Microsoft paint. paste them here. Without clicking anywhere click on crop icon on toolbar.   Now you got your image in the same size as you have in word file. Don’t worry about Image format. Microsoft paint have support for save them in PNG format.

  • What influences running time of reading a bunch of images?

    - by remi
    I have a program where I read a handful of tiny images (50000 images of size 32x32). I read them using OpenCV imread function, in a program like this: std::vector<std::string> imageList; // is initialized with full path to the 50K images for(string s : imageList) { cv::Mat m = cv::imread(s); } Sometimes, it will read the images in a few seconds. Sometimes, it takes a few minutes to do so. I run this program in GDB, with a breakpoint further away than the loop for reading images so it's not because I'm stuck in a breakpoint. The same "erratic" behaviour happens when I run the program out of GDB. The same "erratic" behaviour happens with program compiled with/without optimisation The same "erratic" behaviour happens while I have or not other programs running in background The images are always at the same place in the hard drive of my machine. I run the program on a Linux Suse distrib, compiled with gcc. So I am wondering what could affect the time of reading the images that much?

  • I'm getting a "Does not implement IController" error on images and robots.txt in MVC2

    - by blesh
    I'm getting a strange error on my webserver for seemingly every file but the .aspx files. Here is an example. Just replace '/robots.txt' with any .jpg name or .gif or whatever and you'll get the idea: The controller for path '/robots.txt' was not found or does not implement IController. I'm sure it's something to do with how I've setup routing but I'm not sure what exactly I need to do about it. Also, this is a mixed MVC and WebForms site, if that makes a difference.

  • WPF Blurry Images - Bitmap Class

    - by Luke
    I am using the following sample at http://blogs.msdn.com/dwayneneed/archive/2007/10/05/blurry-bitmaps.aspx within VB.NET. The code is shown below. I am having a problem when my application loads the CPU is pegging 50-70%. I have determined that the problem is with the Bitmap class. The OnLayoutUpdated() method is calling the InvalidateVisual() continously. This is because some points are not returning as equal but rather, Point(0.0,-0.5) Can anyone see any bugs within this code or know a better implmentation for pixel snapping a Bitmap image so it is not blurry? p.s. The sample code was in C#, however I believe that it was converted correctly.

  • javascript replace text with images problem

    I'm extremely new to JS and have this code that I'm trying to tweak.

Basically, I'm trying to change every instance of a card type with an image on a webpage Here's the code: window.onload = function(){ var cardname = new Array(); cardname[0] = "Ace of Hearts^<img src='http://upload.wikimedia.org/wikipedia/commons/thumb/7/7c/Ornamental_h_a.svg/88px-Ornamental_h_a.svg.png' />";

  • RubyQT QGraphicsview scale images to fit window

    I'm trying to make an image scale inside of a QGraphicsView and having zero success. I did find this C++ question with what seemed to be the same problem:http://stackoverflow.com/questions/2489754/qgraphicsview-scrolling-and-image-scaling-cropping I borrowed the approach of overriding the drawback/foreground. However when I run the script I'm greeted with a method_missing error: method_missing: undefined method drawPixmap for #<Qt::Painter:0x7ff11eb9b088> QPaintDevice: Cannot destroy paint device that is being painted What should I be doing to get the QGraphicsView to behave the way I want? class Imageview < Qt::GraphicsView attr_reader :pixmap def initialize(parent=nil) # @parent=parent super() @pixmap=pixmap Qt::MetaObject.connectSlotsByName(self) end def loadimage(pixmap) @pixmap=pixmap end def drawForeground(painter, rect) #size=event.size() #item= self.items()[0] #Qt::GraphicsPixmapItem.new #pixmap=@pixmap #painter=Qt::Painter.new [email protected](Qt::Size.new(rect.width,rect.height),Qt::KeepAspectRatio, Qt::SmoothTransformation) # painter.begin(self) painter.drawPixmap(rect,sized,Qt::Rect.new(0.0, 0.0, sized.width,sized.height)) #painter.end() # item.setPixmap(sized) #painter.end self.centerOn(1.0,1.0) #item.scale() # item.setTransformationMode(Qt::FastTransformation) # self.fitInView(item) end def updateSceneRect painter=Qt::Painter.new() drawForeground(painter,self.sceneRect) end end app=Qt::Application.new(ARGV) #grview=Imageview.new pic=Qt::Pixmap.new('pic') grview=Imageview.new() grview.loadimage(pic) scene=Qt::GraphicsScene.new #scene.addPixmap(pic) grview.setScene(scene) #grview.fitInView(scene) grview.renderHint=Qt::Painter::Antialiasing | Qt::Painter::SmoothPixmapTransform grview.backgroundBrush = Qt::Brush.new(Qt::Color.new(230, 200, 167)) grview.show app.exec

  • PHP/GD - Cropping and Resizing Images

    - by Alix Axel
    I've coded a function that crops an image to a given aspect ratio and finally then resizes it and outputs it as JPG: <?php function Image($image, $crop = null, $size = null) { $image = ImageCreateFromString(file_get_contents($image)); if (is_resource($image) === true) { $x = 0; $y = 0; $width = imagesx($image); $height = imagesy($image); /* CROP (Aspect Ratio) Section */ if (is_null($crop) === true) { $crop = array($width, $height); } else { $crop = array_filter(explode(':', $crop)); if (empty($crop) === true) { $crop = array($width, $height); } else { if ((empty($crop[0]) === true) || (is_numeric($crop[0]) === false)) { $crop[0] = $crop[1]; } else if ((empty($crop[1]) === true) || (is_numeric($crop[1]) === false)) { $crop[1] = $crop[0]; } } $ratio = array ( 0 => $width / $height, 1 => $crop[0] / $crop[1], ); if ($ratio[0] > $ratio[1]) { $width = $height * $ratio[1]; $x = (imagesx($image) - $width) / 2; } else if ($ratio[0] < $ratio[1]) { $height = $width / $ratio[1]; $y = (imagesy($image) - $height) / 2; } /* How can I skip (join) this operation with the one in the Resize Section? */ $result = ImageCreateTrueColor($width, $height); if (is_resource($result) === true) { ImageSaveAlpha($result, true); ImageAlphaBlending($result, false); ImageFill($result, 0, 0, ImageColorAllocateAlpha($result, 255, 255, 255, 127)); ImageCopyResampled($result, $image, 0, 0, $x, $y, $width, $height, $width, $height); $image = $result; } } /* Resize Section */ if (is_null($size) === true) { $size = array(imagesx($image), imagesy($image)); } else { $size = array_filter(explode('x', $size)); if (empty($size) === true) { $size = array(imagesx($image), imagesy($image)); } else { if ((empty($size[0]) === true) || (is_numeric($size[0]) === false)) { $size[0] = round($size[1] * imagesx($image) / imagesy($image)); } else if ((empty($size[1]) === true) || (is_numeric($size[1]) === false)) { $size[1] = round($size[0] * imagesy($image) / imagesx($image)); } } } $result = ImageCreateTrueColor($size[0], $size[1]); if (is_resource($result) === true) { ImageSaveAlpha($result, true); ImageAlphaBlending($result, true); ImageFill($result, 0, 0, ImageColorAllocate($result, 255, 255, 255)); ImageCopyResampled($result, $image, 0, 0, 0, 0, $size[0], $size[1], imagesx($image), imagesy($image)); header('Content-Type: image/jpeg'); ImageInterlace($result, true); ImageJPEG($result, null, 90); } } return false; } ?> The function works as expected but I'm creating a non-required GD image resource, how can I fix it? I've tried joining both calls but I must be doing some miscalculations. <?php /* Usage Examples */ Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '1:1', '600x'); Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '2:1', '600x'); Image('http://upload.wikimedia.org/wikipedia/commons/4/47/PNG_transparency_demonstration_1.png', '2:', '250x300'); ?> Any help is greatly appreciated, thanks.

  • Perf: Viewing thousands of images in Silverlight 3 on a 3D Wall

    - by Bob Holland
    I currently work on a very cool Silverlight app that displays photos in a 3D wall space like the Wall3D demo that is thrown in with Blend 3. The problem I am currently facing is performance. The app works like this: As you scroll right or left the 3d photo wall rotates As each movement is made, the next column of photos are downloaded, decoded into a BitmapImage and thrown into a 3D Wall Node. As you can imagine users (if you let them) will want to flip through the photos really quickly, but the problem I have is I cannot display the photos quick enough. In most cases it's a beautiful app that works really well, but when an album contains over 300 photos, you can imagine the sort of memory taken up by all the BitmapImage classes and how moving the slider can jump from photo 20 to photo 120 in a second. Of course we have algorithms in place to not download every photo in between, but I still can't work out a fast way to get the photos displayed. It may be a case that we need to throw away the 'great for show' 3D wall and go to a flat DeepZoom like wall like the Playboy archive one that Vertigo did. Still not sure, let me know your thoughts. P.S. We are using Kit3D for all the 3D work, it's using PerspectiveCamera, Model3DGroup, ModelVisual3D, RotateTransform3D & TranslateTransform3D. Cheers, Bob.

  • How to upload images from iPhone app developed using Titanium

    - by Karthik.K
    Hi, I finally landed up in developing an iPhone app using Titanium Mobile. Now the problem I face is, Im able to run the app, and the app also sends the image to the server. But Im not able to see the file that got uploaded to the server. I have pasted the iPhone app's code to send image to the server and also, the PHP file that would receive the file from the app. var win = Titanium.UI.currentWindow; var ind=Titanium.UI.createProgressBar({ width:200, height:50, min:0, max:1, value:0, style:Titanium.UI.iPhone.ProgressBarStyle.PLAIN, top:10, message:'Uploading Image', font:{fontSize:12, fontWeight:'bold'}, color:'#888' }); win.add(ind); ind.show(); Titanium.Media.openPhotoGallery({ success:function(event) { Ti.API.info("success! event: " + JSON.stringify(event)); var image = event.media; var xhr = Titanium.Network.createHTTPClient(); xhr.onerror = function(e) { Ti.API.info('IN ERROR ' + e.error); }; xhr.onload = function() { Ti.API.info('IN ONLOAD ' + this.status + ' readyState ' + this.readyState); }; xhr.onsendstream = function(e) { ind.value = e.progress ; Ti.API.info('ONSENDSTREAM - PROGRESS: ' + e.progress+' '+this.status+' '+this.readyState); }; // open the client xhr.open('POST','http://www.myserver.com/tmp/upload2.php'); xhr.setRequestHeader("Connection", "close"); // send the data xhr.send({media:image}); }, cancel:function() { }, error:function(error) { }, allowImageEditing:true }); And here is the PHP code on the server: http://www.pastie.org/891050 I'm not sure where I'm going wrong. Please help me out in this issue. Would love to provide if you need some more information.

  • How to select text, but not images, in CSS

    - by thinkswan
    Simple question: I have the following markup... <a href='#'> <img src='icon.png'> This is the link </a> I want to have the text become underlined on mouseover. What is the CSS selector for selecting only the text in that <a> element and nothing else? I'd rather not wrap it in anything if I don't have to. a:hover { text-decoration: none; } a:hover <select_text_here> { text-decoration: underline; }

  • Deleting a tag from lots of images at once in Aperture?

    - by Bart B
    Aperture makes it easy to tag lost of pictures at once by just selecting all the images, and the dragging and dropping tags from the tags pallet onto the selected images. But when you need to do the reverse, I can't find a way other than editing each image individually. Is there a way I could select multiple images at once and strip a tag out of all of them? Thanks, Bart.

  • Loading Images with Real Screen Resolution (Flash AS3)

    - by yar
    I am loading JPEGs into a Flash presentation using load with a flash.display.Loader and it's working great. The JPEGs are sizing to their native resolution (which is perfect). However, if I maximize the Flash presentation (in the Flash Player), the JPGs do NOT take advantage of the bigger screen. For example, the presentation is 1024x768, and the image is 1280x400. Normally the image shows with a part offscreen in the Flash presentation. However, if I expand the Flash presentation to 1680x1200, the freshly loaded image still goes offscreen. Is there any way to load the jpg (or png, or whatever) to take advantage of the displayed resolution of the Flash presentation? Edit: I realize this question is hard to read, so any help would be appreciated.

  • SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

    - by Kami
    I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

  • Histogram equalisation of colour images with Java

    - by Tunji Gbadamosi
    I'm trying to histogram equalise a colour image with Java. At first I thought about applying the greyscale method to each RGB value, however, I've since learned that this would disrupt the colour distribution of the image. So, my question is: which is a better way to histogram equalise a colour image with Java?

  • Uploading images to a PHP server from Android

    - by Samuh
    I need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST: *$_POST['title']* *$_POST['caption']* *$_FILES['fileatt']* Most of the internet searches suggested either : Download the following classes and trying MultiPartEntity to send the request: apache-mime4j-0.5.jar httpclient-4.0-beta2.jar httpcore-4.0-beta3.jar httpmime-4.0-beta2.jar OR Use URLconnection and handle multipart data myself. Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead. Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work. What is the correct way to get this done in an Android application? Thanks.
