• How to secure images with Rails?

  - by NotDan

  I have a gallery in my rails app that needs to only allow certain images to be shown to specific, logged in users. I am using Paperclip for image processing now, but it saves all images in a public folder available to anyone. Note that I don't have to use Paperclip if there is a better way, and I already have the login system in place. I just need a way to place the images in a non-public location, but still be able to serve them as needed. Is it possible to only allow these images to be served to authenticated users?

• A basic animation not showing up

  - by Rilakkuma

  I still try different basics with android, and now I'm stuck with animation. I'm trying to implement a simple animation. I've defined animation in xml file like this: alpha android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" duration="3000" repeatCount="infinite" In my main view group I have an ImageView defined like this: <ImageView android:id="@+id/someb" android:src="@drawable/earth_normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5dip"/> And this is from my starting activity class: public class Ohayou extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView earth = (ImageView)findViewById(R.id.someb); Animation earthFadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fade_in); earth.startAnimation(earthFadeInAnimation); } It finds ImageView successfuly and creates animation. but when I start emulator ImageView just shows the original src image, not an animation. What am I doing wrong? Thanks

• Non US characters in section headers for a UITableView

  - by epatel

  I have added a section list for a simple Core Data iPhone app. I followed this so question to create it - How to use the first character as a section name but my list also contain items starting with characters outside A-Z, specially Å,Ä and Ö used here in Sweden. The problem now is that when the table view shows the section list the three last characters are drawn wrong. See image below It seems like my best option right now is to let those items be sorted under 'Z' if ([letter isEqual:@"Å"] || [letter isEqual:@"Ä"] || [letter isEqual:@"Ö"]) letter = @"Z"; Someone that have figured this one out? And while I'm at it... 'Å', 'Ä' and 'Ö' should be sorted in that order but are sorted as 'Ä', 'Å' and 'Ö' by Core Data NSSortDescriptor. I have tried to set set the selector to localizedCaseInsensitiveCompare: but that gives a out of order section name 'Ä. Objects must be sorted by section name' error. Seen that too?

• How to store Hierarchical K-Means tree for a large number of images, using Opencv?

  - by AquaAsh

  I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

• should I use Navigator or View State ?

  - by Audrey

  Hi I want to create an application has this sort of function: http://looklet.com/create In this application when you click the button (or some tilelist) on the right the model on the left update accordingly. I wonder how they achieve this. Originally i think it's some sort of image-only pop-up window but then pop-up window seems to update the entire view. Then I think it might be only change view state, but then I still confused how it can be done using view state. Flex expert please give me some hint !

• Display different xsl:attribute depending on the code

  - by Johann

  Dear All, I have the following xsl code in an xsl document <A target="_blank" style="text-decoration=none"> <xsl:attribute name="href">viewdoc.aspx?doc=<xsl:value-of select="URLFilePath"/>&amp;mode=inline</xsl:attribute> <xsl:attribute name="prefix"><xsl:value-of select="FileName"/>: </xsl:attribute> <IMG src="images/word_small.gif" border="0"/> </A> and in the code-behind I am doing this newItemNode = xmlDocument.CreateElement("URLFilePath") newItemNode.InnerText = correctedPath xmlItemNode.ParentNode.AppendChild(newItemNode) Now that works fine for word documents. However I need a way in code to check the extension of the file, and display the correct Image and xsl:attribute depending on the If statement. So the If statement will be like this:- If correctedPath.ToLower.Contains(".doc") Then //display the word icon and attributes Else //display the excel icon and attributes End If Can you please give me some tips and help on how I can achieve this? Thanks

• How to speed this kind of for-loop?

  - by wok

  I would like to compute the maximum of translated images along the direction of a given axis. I know about ordfilt2, however I would like to avoid using the Image Processing Toolbox. So here is the code I have so far: imInput = imread('tire.tif'); n = 10; imMax = imInput(:, n:end); for i = 1:(n-1) imMax = max(imMax, imInput(:, i:end-(n-i))); end Is it possible to avoid using a for-loop in order to speed the computation up, and, if so, how?

• FileNotFoundException when cropping a photo

  - by James G

  I'm trying to crop a photo to use in a Live Wallpaper but I'm getting a FileNotFoundException when the crop activity tries to save my new cropped image. This is the code I'm using: File file = new File(getFilesDir(), "wallpaper.jpg"); Intent intent = new Intent("com.android.camera.action.CROP"); intent.setData(uri); DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); intent.putExtra("outputX", metrics.widthPixels * 2); intent.putExtra("outputY", metrics.heightPixels); intent.putExtra("aspectX", metrics.widthPixels * 2); intent.putExtra("aspectY", metrics.heightPixels); intent.putExtra("scale", true); intent.putExtra("noFaceDetection", true); intent.putExtra("output", Uri.parse("file:/" + file.getAbsolutePath())); startActivityForResult(intent, REQUEST_CROP_IMAGE); The wallpaper.jpg file seems to exist on DDMS file explorer so I'm not sure what I'm doing wrong. Any advice is greatly appreciated.

• Pass a class as a parameter?

  - by JuBu1324

  I have been lead to believe that it is possible to pass a class as a method parameter, but I'm having trouble implementing the concept. Right now I have something like: - (id)navControllerFromView:(Class *)viewControllerClass title:(NSString *)title imageName:(NSString *)imageName { viewControllerClass *viewController = [[viewControllerClass alloc] init]; UINavigationController *thisNavController = [[UINavigationController alloc] initWithRootViewController: viewController]; thisNavController.tabBarItem = [[UITabBarItem alloc] initWithTitle: title image: [UIImage imageNamed: imageName] tag: 3]; return thisNavController; } and I call it like this: rootNavController = [ self navControllerFromView:RootViewController title:@"Contact" imageName:@"my_info.png" ]; What's wrong with this picture?

• Bugs in scroll-follow with Google map (Firefox and Safari)

  - by earlyriser

  A scroll follow effect is when a part of the web design is always visible, even when the window is scrolled. There are animated and static versions of this. The animated is ok http://robertomartinez.info/cobra/index.html But I prefer the fixed version, however I have some bugs: http://robertomartinez.info/cobra/index_fixed.html -In Firefox, when you scroll the page, you will see a kind of vertical cut in the lorem ipsum text (below the HERE indication). This is caused by the image tiles of the map, then if you drag and drop the map, the cut will appear in another side. -In Safari, when you scroll the page, the div follows, but the map images stay in the same position. Do you have solutions for theses issues? Thanks.

• server automatically changes the case of files extensions

  - by AlanChavez

  I have the following problem, if I upload any file to my web server it automatically renames the file to an uppercase extension. For instance: If I upload picture.jpg my server automatically changes it to picture.JPG If I use <img src="picture.jpg"> my server returns a 404 error but if I use <img src="picture.JPG"> then the server displays the image. Can the .htaccess solve this issue? something with RewriteRule and RewriteCond? RewriteCond %{HTTP_HOST} ^$\.jpg [NC] RewriteRule ^(.*)$ $1\.JPG [R=301,L] Any help will be greatly appreciated! Thanks!

• Instantaneous frequency not plotting correctly in Matlab

  - by user2951069

  I'm trying to convert square wave data to instantaneous frequency and plot against time. It works correctly for one data set, but three others are plotting as shown in the image: http://i.imgur.com/iuL648o.png Time is linear, so it shouldn't be plotting like that. Anyone have any ideas as to what's going on? I'm using the following code: ddiff = diff(flow(:,1)); locations = find(ddiff(1:end-1,1)>0.1 & ddiff(2:end,1) <=0.1); for z = 2:length(locations) inst_freq(z-1) = 1/(time(locations(z))-time(locations(z-1))); freq_time(z-1) = time(locations(z)); end plot(freq_time,inst_freq)

• One table for uploads for multiple resources in CakePHP

  - by Mef

  Hi, I have CakePHP app in which I'd like to attach gallery to multiple resources. Let's say I've got artists, each one has own gallery. I've got articles, every article has some images attached to it and so on. Now I set up tables like this: Artists hasMany Artistimages, fields in artistimages table are: id, artist_id, filename, filetype, filesize etc. Articles hasMany Articleimages, fields in articleimages table are: id, article_id, filename, filetype, filesize etc. ...but this is not how it should be, I think. Is there possibility to have one table called for example uploads which will contain all images with foreign key pointing to resource its reffering to? How to tell CakePHP which image is coming from which resource?

• jquery custom drag and drop

  - by samlochner

  I am trying to create functionality similar to drag and drop. I need to create my own as there will be some significant differences to the drag and drop in the jquery UI. I would like to have mousemove being called repeatedly at all times, and mousedown called every time the mouse is pressed. So I have the following code: $(document).bind('mousemove',function(e){ $("#coords").text("e.pageX: " + e.pageX + ", e.pageY: " + e.pageY); }); $(document).bind('mousedown',function(e){ }); ('coords' is the id of a div) As I move the mouse, coordinates are reported correctly in 'coords'. If I depress a mouse button and then move the mouse, coordinates are still reported correctly. But if I depress a mouse button on an image and then move the mouse, coordinates are reported correctly for a few sets, and then they seize up! Why is this happening and how can I fix it? Thanks, Sam

• Will Algorithm written in OCaml compiled from C be Faster than Algorithm written in Pure C code?

  - by Ole Jak

  So I have some cool Image Processing algorithm. I have written it in OCaml. It performs well. I now I can compile it as C code with such command ocamlc -output-obj -o foo.c foo.ml (I have a situation where I am not alowed to use OCaml compiler to bild my programm for my arcetecture, I can use only specialy modified gcc. so I will compile that programm with sometyhing like gcc -L/usr/lib/ocaml foo.c -lcamlrun -lm -lncurses and Itll run on my archetecture.) I want to know in general case will my OCaml code compiled into C run faster than algorithm implemented in pure C?

• Need to dynamically-generate a "sticky note" text

  - by gravyface

  Working on a website that has an image of a sticky note which will change text somewhat frequently (every month or so) as new "todo" items are created on it. Font I'm currently using is not Web Safe and the text is slightly angled to match the skew of the sticky note as well. Now I'm a pragmatist, and in situations like this I would normally secede defeat and opt for something more CSS/HTML practical. But no more! I'm falling a bit behind on what's going on with HTML5, CSS3, PNG graphics, Flash (ugh), and/or any other rich visuals. I'm decent with PHP/CSS/JS (jquery), have dabbled in Flash/actionscript too. My question is: what tools/method should I be looking at here?

• How do I write a Photoshop Extension (8BX) plugin?

  - by Oliver Ahul

  The Adobe Photoshop CS3/4 SDk has a lot of examples for Filter, Import, Export etc plugins but I havent found anything that illustrates how to write a 8BX plugin. Reason I need to write one is to add a new drop down menu to the Photoshop root toolbar (where it displays File, Edit, Image .. Window. Help drop down menus). I have seen product like OneSoftware install an 8BX plugin into Adobe Photoshop CS3\Plug-Ins\Extensions directory that causes PS to add adrop down menu for OneSoft. That suggest this is a solvable problem :-) I tried by changing an existing plugin in the SDlK samples but no go. Specifically i modified the resource file: resource 'PiPL' (ResourceID, plugInName " PiPL", purgeable) { { Kind { **Extension** }, Name { plugInName "..." }, ... Despite using the Extension Kind , PS never loads the plugin. It doesnt generate any compile time or load error either. Anyone has ideas on how to go about doing this ? Thanks

• Stubborn UIButton

  - by Mike

  I have a UIButton that is supposed to be disabled during certain phases. So, when this happens I do [myButton setEnabled:NO]; This is perfect because the button stays grayed and if clicked will not trigger its action, but... when the button is clicked even grayed, it enables again and a second click will trigger its actions (???????!!!!!!!!!!). How can that be? If the button is disabled it is supposed to be "part of the background", i.e., an image without any action. I have tried to make the button vanish using alpha but even if you click on the empty spot, it reappears after the first click and then can trigger actions after the second click... (????) Am I missing something?

• Android ImageButton / Custom-Button?

  - by user568306

  Hi everyone, I am new to android development. So far I could help myself in all matters by reading threads here on stackoverflow. Now I am stuck and need someones help. Unfortunately I am not allowed to post an image of a screenshot because I am a new mamber, so I try to descripe it. I have a Samsung Galasy S and the clock app that ships with it has an button called "+ Create alarm". I want to create a similar button for my app. I've been experimenting with ImageButton. I do know how to get that "+"-Icon onto an ImageButton, but only centered and without text. I guess this is a custom button. Does anyone know how to do this? Can I do it in xml or do I need to extend the view-class and make it my own view?

• ASP.NET Website or Web service?

  - by fireBand

  Hi, I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request. There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service. Is this a better approach? Does ASP.NET Website offer better performance that a Web-service? Which one would be better is this situation? Thanks in advance.

• How to add "loading" screen for UIWebView app each time new page is being loaded?

  - by AragornSG

  I have an app that works with tabs and webview. I already have it setup to refresh the page assigned to a tab each time the item on tabbar is selected. My problem now is that it takes some time to load the page and it's impossible to say if the page being displayed is the old or refreshed one. What I want to do is add a "loading" screen (a simple image) which will be displayed until the refreshed page is loaded. Here is the function I run on each tab tap: - (void) goToPage:(NSString *)sid { NSString *newURL = [NSString stringWithFormat:@"%@/mykingdom.php?sid=%@", appURL, sid]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks!
