  • Using JavaScript to change the URL used when a page is bookmarked...

    - by user30997
    JavaScript doesn't allow you to update window.location without triggering a reload. While I agree with this policy in principle (it shouldn't be possible to visit my website and have JavaScript change the location bar to read www.yourbankingsite.com,) I believe that it should be possible to change www.foo.org/index to www.foo.org/help. The only reason I care about this is for bookmarking. I'm working on a photo browser, and when a user is previewing a particular image, I want that image to be the default if they should bookmark that page. For example, if they are viewing foo.org/preview/images0-30 and they click on image #15, that image is expanded to a medium-sized view. If they then bookmark the page, I want the bookmark URL to be foo.org/preview/images0-30/active15. Any thoughts, or is there a security barrier on this one as well? I can certainly understand the same policy being applied here, but one can dream.

  • How do I use a string as a keyword argument?

    - by Issac Kelly
    Specifically, I'm trying to use a string to arbitrairly filter the ORM. I've tried exec and eval solutions, but I'm running into walls. The code below doesn't work, but it's the best way I know how to explain where I'm trying to go from gblocks.models import Image f = 'image__endswith="jpg"' # Would be scripted in another area, but passed as text <user input> d = Image.objects.filter(f) #for the non-django pythonistas: d = Image.objects.filter(image__endswith="jpg") # would be the non-dynamic equivalent.

  • UITableViewCell separator line disappears on scroll

    - by iconso
    I'm trying to have a separator cell with a custom image. I did try something like that: In my cellForRowAtIndexPath: NSString *cellIdentifier = [NSString stringWithFormat:@"identifier"]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier]; } cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:19]; cell.textLabel.text = [self.menuItems objectAtIndex:indexPath.row]; cell.textLabel.textColor = [UIColor colorWithRed:128/255.0f green:129/255.0f blue:132/255.0f alpha:1.0f]; cell.backgroundColor = [UIColor whiteColor]; UIImageView *imagView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"reaL.png"]]; imagView.frame = CGRectMake(0, cellHeight, cellWidth, 1); [cell.contentView addSubview:imagView]; switch (indexPath.row) { case 0: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"img1.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"route.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 1: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"img.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"money.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 2: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"auto.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"cars.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 3: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"impostazioni.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"impostazioni.png"] scaledToSize:CGSizeMake(27, 27)]; // cell.imageView.contentMode = UIViewContentModeScaleAspectFill; break; case 4: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"info.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"info.png"] scaledToSize:CGSizeMake(27, 27)]; break; default: break; } return cell; When I lunch the app everything is good, but when I scroll the the table, or when I select a cell the separator lines disappear. How I can have a permanent custom line separator?

  • Distance between hyperplanes

    - by michael dillard
    I'm trying to teach myself some machine learning, and have been using the MNIST database (http://yann.lecun.com/exdb/mnist/) do so. The author of that site wrote a paper in '98 on all different kinds of handwriting recognition techniques, available at http://yann.lecun.com/exdb/publis/pdf/lecun-98.pdf. The 10th method mentioned is a "Tangent Distance Classifier". The idea being that if you place each image in a (NxM)-dimensional vector space, you can compute the distance between two images as the distance between the hyperplanes formed by each where the hyperplane is given by taking the point, and rotating the image, rescaling the image, translating the image, etc. I can't figure out enough to fill in the missing details. I understand that most of these are indeed linear operators, so how does one use that fact to then create the hyperplane? And once we have a hyperplane, how do we take its distance with other hyperplanes?

  • Dragging Custom Node in JavaFX

    - by Karussell
    I cannot get it working although I am very close to an acceptable solution. I can drag the Dock if it is only a rectangle. But if I add a node (e.g. an image) to this dock I am not able to get a working solution. Do you have a code snippet, link or other advices for me? Here is my code: public class Dock extends CustomNode { // initialize this with an 64x64 image of your choice // via ImageView { image: Image {..}} public var content: Node[]; public var width = 64; public var height = 64; public var xOffset: Number = 0; public var yOffset: Number = 0; var imgX: Number = 0; var imgY: Number = 0; var distX: Number; var distY: Number; public var rasterX = function (n: Number): Number { var MAX = 4 * 64; if (n < 0) { return 0 } else if (n > MAX) { return MAX } else return n } public var rasterY = rasterX; override protected function create(): Node { Group { // if we place the translate here then the whole dock will flicker //translateX: bind imgX; //translateY: bind imgY; content: [ Rectangle { // ... and here 'content' won't be dragged translateX: bind imgX; translateY: bind imgY; height: bind height width: bind width fill: Color.LIGHTGRAY strokeWidth: 4 stroke: Color.BLACK }, content] onMousePressed: function (e: MouseEvent): Void { xOffset = e.x; yOffset = e.y; // Calculate the distance of the mouse point from the image // top-left corner which will always come out as positive value distX = e.x - imgX; distY = e.y - imgY; } onMouseDragged: function (e: MouseEvent): Void { // Find out the new image postion by subtracting the distance // part from the mouse point. imgX = rasterX(e.x - distX); imgY = rasterY(e.y - distY); } } }

  • NLP: any easy and good methods to find semantic similarity between words?

    - by sadawd
    Dear Everyone, I don't know whether stackoverflow covers NLP, so I am gonna give this a shot. I am interested to find the semantic relatedness of two words from a specific domain, i.e. "image quality" and "noise". I am doing some research to determine if reviews of a cameras are positive or negative for a particular attribute of the camera. (like image quality in each one of the reviews). However, not everybody uses the exact same wording "image quality" in the posts, so I am out to see if there is a way for me to build something like that: "image quality" which includes ("noise", "color", "sharpness", etc etc) so I can wrap all everything within one big umbrella. I am doing this for another language, so Wordnet is not necessarily helpful. And no, I do now work for Google or Microsoft so I do not have data from people's clicking behavior as input data either. However, I do have a lot of text, pos-tagged, segmented etc. Thanks

  • Drag and drop objects onto a DIV.. relative vs absolute position and size of target DIV

    - by Scott
    Hi, I have a question about drag and drop and hoping one of you already solved it. I have an online web app where I can drag and drop annotations (arrows, stars) on top of an image that sits on a DIV. Here's some things to know. 1) The image can be any size (sometimes big sometimes small) 2) The DIV of wrapper can be left aligned or centered 3) The DIV of wrapper can be fixed or auto So is there any possible solution to make it so positions of annotations are always relative to the top left corner of the image? So I am using jQuery. How would I get an annotation's position always relative to the top left corner of an image once I drop object? Thanks!

  • MATLAB: draw centroids

    - by Myx
    Hello - my main question is given a feature centroid, how can I draw it in MATLAB? In more detail, I have an NxNx3 image (an rgb image) of which I take 4x4 blocks and compute a 6-dimensional feature vector for each block. I store these feature vectors in an Mx6 matrix on which I run kmeans function and obtain the centroids in a kx6 matrix, where k is the number of clusters and 6 is the number of features for each block. How can I draw these center clusters in my image in order to visualize if the algorithm is performing the way I wish it to perform? Or if anyone has any other way/suggestions on how I can visualize the centroids on my image, I'd greatly appreciate it. Thank you.

  • Responsive grid, floated elements move underneath one another when min-width is reached

    - by Francesca
    I'm in the process of creating a responsive site (currently only working on the main content.) I've created two floated divs with percentage based widths. One contains an image which resizes with the browser resizing. The image has a min-width of 100px. Can anyone tell me why when put into a mobile sized width it doesn't drop down? How can I make the image stack underneath the text? JS Fiddle Live site

  • Valid HTTP header? `GET /page.html Http1.0`?

    - by Earlz
    Ok so I've been reading up on HTTP and found this page. This is an example HTTP request that was posted there: GET /http.html Http1.1 Host: www.http.header.free.fr Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, Accept-Language: Fr Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0) Connection: Keep-Alive I tried it in telnet and it worked. But everywhere else I see this kind of request line GET /http.html HTTP/1.1 The important different is that HTTP is all caps and the / character. Are they both correct? They both seem to work on the sites I've tested it on. I've skimmed the RFC of HTTP but didn't find anything of use. Has anyone else seen this kind of request header? Is it officially supported?

  • How can I change the arrow style in a JComboBox

    - by Stephane Grenier
    Let's say I want to use a custom image for the arrow in JComboBox, how can I do this? I understand it's possible using the synth xml files, or maybe even UIManager.put(...), but I don't know how. All I want to do at this time is change the arrow image to something else, either programatically or even just overriding the image it uses. How exactly can I do this?

  • Error when passing data between views

    I'm using a plist (array of dictionaries) to populate a tableview. Now, when a cell i pressed, I want to pass the reprecented dictionary to the detail view with a segue.

  • mocking static method call to c# library class

    - by Joe
    This seems like an easy enough issue but I can't seem to find the keywords to effect my searches. I'm trying to unit test by mocking out all objects within this method call. I am able to do so to all of my own creations except for this one: public void MyFunc(MyVarClass myVar) { Image picture; ... picture = Image.FromStream(new MemoryStream(myVar.ImageStream)); ... } FromStream is a static call from the Image class (part of c#). So how can I refactor my code to mock this out because I really don't want to provide a image stream to the unit test.

  • [PHP-GD] Background transperancy in imagerotate()

    - by KPL
    Hello people, Since last 2 days, I was trying to add transperancy to the background after rotating an image using imagerotate() PHP-GD function. But, to my great disappointment, it's not working at all. It's just giving out a black background behind it. Here's my code - $patchImageS = 'image.png'; // the image to be patched over the final bg $patchImage = imagecreatefrompng($patchImageS); // resource of image to be patched $patchImage = imagerotate($patchImage, 23, 0, 0); imagepng($patchImage,'tt.png'); I tried to change the parameters being passed in function to imagerotate($patchImage, 23, 5, 0); imagerotate($patchImage, 23, 0, 5); Any help would be highly appreciated.

  • Android - Take a photo, save it in app drawables and display it in an ImageButton

    - by Andres7X
    I have an Android app with an ImageButton. When user clicks on it, intent launches to show camera activity. When user capture the image, I'd like to save it in drawable folder of the app and display it in the same ImageButton clicked by the user, replacing the previous drawable image. I used the activity posted here: Capture Image from Camera and Display in Activity ...but when I capture an image, activity doesn't return to activity which contains ImageButton. Edit code is: public void manage_shop() { static final int CAMERA_REQUEST = 1888; [...] ImageView photo = (ImageView)findViewById(R.id.getimg); photo.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent camera = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(camera, CAMERA_REQUEST); } }); [...] } And onActivityResult(): protected void onActivityResult(int requestCode, int resultCode, Intent data) { ImageButton getimage = (ImageButton)findViewById(R.id.getimg); if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) { Bitmap getphoto = (Bitmap) data.getExtras().get("data"); getimage.setImageBitmap(getphoto); } } How can I also store the captured image in drawable folder?

  • FLEX: UIComponent Click Handler??

    - by davidemm
    Hello, Thanks for reading. I'm trying to put a label and an image on a UIComponent, side-by-side. I want to use UIComponent for efficiency reasons, and the entire component is more complicated than just a button with an icon. I'm trying to get a click handler on ther entire UIComponent so that when a click happens on either the label or the image, the same [click] event handler is called. If I add a click handler on the root component, it works, but when I introduce space between the label and the image, the space between them becomes un-clickable. I produce the space by using the move(x,y) method for the label and the image with a small gap between the x/y coordinates. Any ideas how to remedy this? Thanks.
