  • Attachment_fu: can't disable :partition option

    - by Nathan Long
    I'm trying to use the Attachment_Fu plugin in a Rails project, and want to customize the paths where uploaded files are saved. The documentation shows this option: :partition # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. (The 0001 part is an ID from a table.) I don't want that, so I set the partition option to false, like so: class Photo < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 500.kilobytes, :resize_to => '320x200', :thumbnails => {:thumb => '100x100>' }, :partition => false validates_as_attachment end ...but the :partition => false option has no effect. Has anybody else encountered this problem? How did you fix it?

  • Iphone UIButton not working in nested UIViews

    - by Charles Peterson
    This is so damn simple im sure! Im missing something and im exhausted from trying to fix it. hopefully someone can help. The Button in CharacterView.m works but the button nested down in CharacterMale.m does not. I'm not using IB everything is done progmatically. What would cause one button to work and other not? ///////////////////////////////////////////////////////////////////////////////// CharacterController.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterController.h" #import "CharacterView.h" @implementation CharacterController - (id)init { NSLog(@"CharacterController init"); self = [ super init ]; if (self != nil) { } return self; } - (void)loadView { [ super loadView ]; characterView = [ [ CharacterView alloc ] init]; self.view = characterView; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)dealloc { [super dealloc]; } @end ///////////////////////////////////////////////////////////////////////////////// CharacterView.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterView.h" #import "CharacterMale.h" @implementation CharacterView - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { characterMale = [ [ CharacterMale alloc ] init]; [self addSubview: characterMale]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 200, 200, 100); [button setImage:[UIImage imageNamed:@"btnCharSelect.png"] forState:UIControlStateNormal]; [button addTarget:self action:@selector(ApplyImage:) forControlEvents:UIControlEventTouchUpInside]; [ self addSubview: button ]; } return self; } - (void)drawRect:(CGRect)rect { } -(void)ApplyImage:(id)sender { NSLog(@"CharacterView button works"); } - (void)dealloc { [super dealloc]; } @end ///////////////////////////////////////////////////////////////////////////////// CharacterMale.m ///////////////////////////////////////////////////////////////////////////////// #import "CharacterMale.h" #import "CharacterController.h" @implementation CharacterMale - (id)init { self = [ super init]; if (self != nil) { UIImage *image = [UIImage imageNamed:@"charMale.png"]; imageView = [[ UIImageView alloc] initWithImage:image]; [image release]; [ self addSubview: imageView ]; UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(0, 0, 200, 100); [button setImage:[UIImage imageNamed:@"btnCharSelect.png"] forState:UIControlStateNormal]; [button addTarget:self action:@selector(ApplyImage:) forControlEvents:UIControlEventTouchUpInside]; [ self addSubview: button ]; } return self; } -(void)ApplyImage:(id)sender { NSLog(@"CharacterMal button works"); } - (void)dealloc { [super dealloc]; } @end

  • How do I forward map a point in OpenCV using mapx & mapy?

    - by Charles
    Ultimately, I'm trying to determine the 3D location of a point I've identified in two cameras (using OpenCV 2.3.1, Windows 7, C++). I'm having trouble locating the 2D point for each camera from its mapx & mapy. I could not find in Bradski & Kaehler's OpenCV book how to do it. PROCESS calibrateCamera for each of the pair stereoCalibrate stereoRectify detect the blob I want to locate in 3D on each camera in 2D initUndistortRectifyMap for each camera Eventually, perspectiveTransform PROBLEM with 5: I have the x and y location of the point in the distorted and unrectified image for each camera(from #4) but I don't know how to get the undistorted and rectified x and y for each camera from the two maps initUndistortRectifyMap creates for each camera. I don't want to remap the whole image since I only want to learn the 3D location of one object for each frame. QUESTION: How do I forward map a point (get the undistorted and rectified x and y) with its two maps? Thanks for any help.

  • Texture2D.GetData fails to return pixel colour data

    - by Chris Charabaruk
    Because I'm using sprite sheets instead of an individual texture per sprite, I need to pass in a Rectangle when calling Texture2D.GetData() in my collision detection for per-pixel tests. Unfortunately, without fail I get an ArgumentException percolated down from an internal method inside the Texture (not Texture2D) class. My code for getting the texture data looks like this: public override Color[] GetPixelData() { Color[] data = new Color[(int)size.Product()]; Rectangle rect = new Rectangle(hframe * (int)size.X, vframe * (int)size.Y, (int)size.X, (int)size.Y); #if DEBUG if (sprite.Bounds.Contains(rect) && sprite.Format == SurfaceFormat.Color) #endif sprite.GetData(0, rect, data, 0, 1); return data; } Even with the check to ensure I'm grabbing a valid rectangle and that the texture format matches what I'm trying to get, I still get that exception, claiming "The size of the data passed in is too large or too small for this resource." Unfortunately, the debugger won't let me check the locals within the Texture.ValidateTotalSize() method where the exception originates. Has anyone else had this problem and knows how to fix it? I'm relying on AABB testing only for now, but that doesn't really work for some of my game's entities due to odd shapes, rotation and scaling.

  • Strange behavior of RigidBody with gravity and impulse applied

    - by Heisenbug
    I'm doing some experiments trying to figure out how physics works in Unity. I created a cube mesh with a BoxCollider and a RigidBody. The cuve is laying on a mesh plane with a BoxCollider. I'm trying to update the object position applying a force on its RigidBody. Inside script FixedUpdate function I'm doing the following: public void FixedUpdate() { if (leftButtonPressed()) this.rigidbody.AddForce( this.transform.forward * this.forceStrength, ForceMode.Impulse); } Despite the object is aligned with the world axis and the force is applied along Z axis, it performs a quite big rotation movement around its y axis. Since I didn't modify the center of mass and the BoxCollider position and dimension, all values should be fine. Removing gravity and letting the object flying without touching the plane, the problem doesn't show. So I suppose it's related to the friction between objects, but I can't understand exactly which is the problem. Why this? What's my mistake? How can I fix this, or what's the right way to do such a moving an object on a plane through a force impulse?

  • Sending BLOBs in a JSON service,... how?

    - by Marten Sytema
    Hello I have a webservice (ie. servlet) implemented in Java. It gets some data from a MySQL table, with one column being of type BLOB (an image), and some other columns are just plain text. Normally I would store the file outside the database with a pointer to it in the database, but due to circumstance I now have to use this BLOB column... What is the proper way to send this? How to encode the image in a JSONObject, and how to parse (and RENDER!) it on the otherside ? I want to use JSONP, to avoid having to proxy it through the consumer's webserver. So that the consumer can just put in a tag pointing to the webservice, calling a callback. Any thoughts how to handle images in this situation? Also thoughts on performance etc. are interesting!

  • Palm webOS CSS Targeting Hack?

    - by Tom
    Although it is not good practice, I am looking for a CSS hack to target Palm webOS. The problem is that Safari 3+ is awesome, and I can do some things like gradient background animations on text, but only in Safari. Right now I use @media screen and (-webkit-min-device-pixel-ratio:0) {} and it works like a charm, no Opera, Firefox, or whatever, because if I set the background to the image as I do in Safari they will all be ruined. But Palm's browser is based on webkit, and it uses the rules inside, and Palm's browser doesn't support text backgrounds so all I get is the image moving, no text. I would prefer a CSS hack, but if need be a Javascript one will do.

  • Call glutinit in a PHP extension

    - by Yijinsei
    Hi guys, I am developing a php extension that require the use of opengl. I tried to initialize the library with glutinit; it works in CLI environment but when I tried on browser it doesn't seem to execute the code. The code is actually executed on the server side. It is part of a process to extract features from an image, and the server will return a list of closest image to the user. I very new to opengl, so I'm not sure what kind of error is this, does anybody have any knowledge with this?

  • Linux, how to capture screen, and simulate mouse movements.

    - by 2di
    Hi All I need to capture screen (as print screen) in the way so I can access pixel color data, to do some image recognition, after that I will need to generate mouse events on the screen such as left click, drag and drop (moving mouse while button is pressed, and then release it). Once its done, image will be deleted. Note: I need to capture whole screen everything that user can see, and I need to simulate clicks outside window of my program (if it makes any difference) Spec: Linux ubuntu Language: C++ Performance is not very important,"print screen" function will be executed once every ~10 sec. Duration of the process can be up to 24 hours so method needs to be stable and memory leaks free (as usuall :) I was able to do in windows with win GDI and some windows events, but I'ev no idea how to do it in Linux. Thanks a lot

  • General zoom algorithm for drawing program

    - by Steven Sproat
    My GUI toolkit, wxPython provides some methods for implementing a user zoom factor, however the quality isn't too good. I'm looking for ideas on how to create a zooming feature, which I know is complicated. I have a bitmap representing my canvas which is drawn to. This is displayed inside a scrolled window. Problems I forsee: - performance when zoomed in and panning around the canvas - difficulties with "real" coordinates and zoomed in coordinates - image quality not degrading with the zoom Using wxPython's SetUserScale() on its device contexts presents image quality like this - this is with a 1px line, at 30% zoomed in. I'm just wondering the general steps I'll need to take and the challenges I'll encounter. Thanks for any suggestions

  • dojo connect mouseover and mouseout

    - by peirix
    When setting up dojo connections to onmouseover and onmouseout, and then adding content on mouseover, dojo fires the onmouseout event at once, since there is new content. Example: dojo.query(".star").parent().connect("onmouseover", function() { dojo.query("span", this).addContent("<img src='star-hover.jpg'>"); }).connect("onmouseout", function() { dojo.destroy(dojo.query("img", this)[0]); }); The parent() is a <td>, and the .star is a span. I want to add the hover image whenever the user hovers the table cell. It works as long as the cursor doesn't hover the image, because that will result in some serious blinking. Is this deliberate? And is there a way around it?

  • iPhoneOS SDK - Remove Corner Rounding from views (iPad problem)

    - by norskben
    Hi Guys This might be a little bit picky, but in the iPad SplitViewController setup, there are 2 views. Each of the views has a very small black corner rounding. (This is probably the same with iPhone apps too). This rounding is visible in the image below. What I would like to do is remove the black rounding, so the UI doesnt get these two little bumps along the bottom. Has anyone done this, or know how to? -Its surely possible. Hopefully some one has seen this before. Thanks Image Link Mirror

  • Reading Images only from Camera

    - by Ankit
    I wanted to read images only from the Camera folder of the device. Since the folder might be different for different devices, how can I write a simple application for it). So far I have written the following code, which does read from Camera folder, but it also reads from other places on sdcard as well. Cursor childCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, MediaStore.Images.ImageColumns._ID, null); do { ImageView image = new ImageView(); image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ childCursor.getString( childCursor.getColumnIndex( MediaStore.Images.ImageColumns._ID ))); <some other code> } while (childCursor.moveToNext()); How can I create a generic app and filter on Camera Images before displaying. Any help is appreciated.

  • How to pass parameters to Apache Pivot's wtkx:include tag?

    - by Andrew Swan
    I need to create a reusable UI component that accepts a number of parameters (e.g. an image URL and some label text), similar to how JSP tags can accept parameters. The Pivot docs for the "wtkx:include" tag say: The tag allows a WTKX file to embed content defined in an external WTKX file as if it was defined in the source file itself. This is useful for ... defining reusable content templates I was hoping that I could define my component in a WTKX file using standard Pivot components (e.g. a TextInput) and pass it one or more parameters; for example my reusable template called "row.wtkx" might contain a row with an image and a text field, like this (where the ${xxx} bits are the parameters): <TablePane.Row xmlns="org.apache.pivot.wtk"> <ImageView image="@images/${image_url}" /> <TextInput text="${title}" /> </TablePane.Row> I could then reuse this component within a TablePane as follows: <rows> <TablePane.Row> <Label text="Painting"/> <Label text="Title"/> </TablePane.Row> <wtkx:include src="row.wtkx" image_url="mona_lisa.jpg" title="Mona Lisa"/> <wtkx:include src="row.wtkx" image_url="pearl_earring.jpg" title="Girl with a Pearl Earring"/> <wtkx:include src="row.wtkx" image_url="melting_clocks.jpg" title="Melting Clocks"/> </rows> I've made up the ${...} syntax myself just to show what I'm trying to do. Also, there could be other ways to pass the parameter values other than using attributes of the "wtkx:include" tag itself, e.g. pass a JSON-style map called say "args". The ability to pass parameters like this would make the include tag much more powerful, e.g. in my case allow me to eliminate a lot of duplication between the table row declarations. Or is "wtkx:include" not the right way to be doing this?

  • openCV usage cvFindDominantPoints

    - by rsinha
    Hi, Does anyone know how to use the cvFindDominantPoints API of openCV? I basically have a 1 channel, binary image from which I get a set of contours. Judging from the image, I seem to be getting the correct contours. Now, I am selecting one of these contours to get dominant points of. This contour has about 60 vertices. However, the API call to cvFindDominantPoints is giving me a sequence of points (about 15) that does not even lie on the contour. It is quite far from it. Any insight? my usage: CvSeq *dominantpoints = cvFindDominantPoints(targetSeq, tristorage, CV_DOMINANT_IPAN, 7, 9, 9, 150);

  • Using jQuery to store basic text string in mySQL base?

    - by Kenny Bones
    Could someone point me in the right direction here? Basically, I've got this jQuery code snippet: $('.bggallery_images').click(function () { var newBG = "url('" + $(this).attr('src'); var fullpath = $(this).attr('src'); var filename = fullpath.replace('img/Bakgrunner/', ''); $('#wrapper').css('background-image', newBG); // Lagre til SQL $.ajax({ url: "save_to_db.php", // The url to your function to handle saving to the db data: filename, dataType: 'Text', type: 'POST', // Could also use GET if you prefer success: function (data) { // Just for testing purposes. alert('Background changed to: ' + data); } }); }); This is being run when I click a certain button. So it's actually within a click handler. If I understand this correctly, this snippet takes the source if the image I just clicked and strips it so I end up with only the filename. If I do an alert(filename), I get the filename only. So this is working ok. But then, it does an ajax call to a php file called "save_to_db.php" and sends data: filename. This is correct right? Then, it does a callback which does an alert + data. Does this seem correct so far? Cause my php file looks like this: <?php require("dbconnect2.php"); $uploadstring = $_POST['filename']; $sessionid = $_SESSION['id']; echo ($sessionid); mysql_query("UPDATE brukere SET brukerBakgrunn = '$uploadstring' WHERE brukerID=" .$_SESSION['id']); mysql_close(); ?> When I click the image, the jQuery snippet fires and I get the results of this php file as output for the alert box. I think that the variables somehow are empty. Because notice the echo($sessionid); which is a variable I've created just to test what the session ID is. And it returns nothing. What could be the issue here? Edit: I just tried to echo out the $uploadstring variable as well and it also returns nothing. It's like the jQuery snippet doesn't even pass the variable on to the php file?

  • How to perform game object smoothing in multiplayer games

    - by spaceOwl
    We're developing an infrastructure to support multiplayer games for our game engine. In simple terms, each client (player) engine sends some pieces of data regarding the relevant game objects at a given time interval. On the receiving end, we step the incoming data to current time (to compensate for latency), followed by a smoothing step (which is the subject of this question). I was wondering how smoothing should be performed ? Currently the algorithm is similar to this: Receive incoming state for an object (position, velocity, acceleration, rotation, custom data like visual properties, etc). Calculate a diff between local object position and the position we have after previous prediction steps. If diff doesn't exceed some threshold value, start a smoothing step: Mark the object's CURRENT POSITION and the TARGET POSITION. Linear interpolate between these values for 0.3 seconds. I wonder if this scheme is any good, or if there is any other common implementation or algorithm that should be used? (For example - should i only smooth out the position? or other values, such as speed, etc) any help will be appreciated.

  • How to best deal with photos passed to IFilter?

    - by sharptooth
    I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

  • Compact Framework - ListView like control ?

    - by no9
    Hello. I have been playing with Compact Framework lately and i need some advice. I have a collection of items. One of the properties on each item is a string type that holds XML. This XML defines image, font, style etc... Im looking for a control (similar to listView) that would replace listBox control. Im not satisfied with listView control, because it is very limited on items level. The control has to be dynamic enough so that my parser could parse the XML and customise the control. For a start i would like to show an image and perhaps some font styles for each row in the control. Here is a sample what im trying to achieve: Any suggestions?
