  • Uri for bitmap in subfolder (c# wpf)

    - by the empirical programmer
    I have a wpf app where I'm using an image. To reference the image I use: Uri uri = new Uri("pack://application:,,,/assemblyName;Component/myIcon.png"); BitmapImage(uri) If I add the png directly under the csproj file (with its properties BuildAction=Resource) then it works fine. But I want to move it to a subfolder under the csproj. Another SO question asked about bitmaps\uri's (857732) and an answer linked to this msdn. So I tried : Uri uri = new Uri("pack://application:,,,/assemblyName;Component/Icons/myIcon.png"); But that did not work. Any ideas?

  • CKEditor adds html entities to inline CSS. Is the CSS still valid?

    - by Mihai Secasiu
    I have this piece of code: <table style="background-image: url(path/to_image.png)"> And when I load it in CKEditor it's transformed in: <table style="background-image: url(&quot;path/to_image.png&quot;)"> Is this still still valid CSS? Actually I'm not so interested if it's valid but if there would be any problems with any web browser or email client ( the editor is used for composing a html email ). Firefox and Thunderbird seem to be fine with it.

  • How can I receive CameraActivities result in a DIFFERENT Activity (i.e. not in the launching one)?

    - by steff
    Hi, I hope the title says it all: I've got Activity A which fires up the Camera intent via: Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intent, REQUEST_CAMERA); After the picture is taken I can easily grab the picture in: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) But I'd like to receive the result in Activity B in which the image can be edited. Right now I'm receiving the result in Activity A and pass it over to Activity B which results in showing the GUI of Activity A for a short while: Intent i = new Intent().setAction("DisplayJPEG"); i.setClass(this, EditImageActivity.class); i.putExtra("IMAGE_URI", uri); startActivityForResult(i, REQUEST_EDIT_IMAGE); Of course, I will need the result from Activity B in Activity A after the image has been edited. But that should work with: setResult(resultCode, data); So there has to be a way to do what I need. Please point me into the right direction. Thanks in advance, steff

  • Refreshing a binding that uses a value converter

    - by Hadi Eskandari
    I have a WPF UI that is bound to an object. I'm using a ValueConverter to convert a property to a specific image by a business rule: public class ProposalStateImageConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { var proposal = value as Proposal; var basePath = "pack://application:,,,/ePub.Content;component/Images/General/Flag_{0}.png"; string imagePath; if(proposal.Invoice != null) { imagePath = string.Format(basePath, "Good"); } else { imagePath = string.Format(basePath, "Warning"); } var uri = new Uri(imagePath); var src = uri.GetImageSource(); //Extention method return src; } } It is working fine, but later, when the object's state changes, I want to refresh the image and make the value converter reevaluate. How is this possible?

  • flash with recaptcha or any other captcha solution

    - by Katsuke
    Hello there, I have been looking over the internet for a while about this, but it doesn't seem like there is any information available specifically related to captcah and flash. My purpose is to create an image up-loader on flash, and implement "recaptcha" on it, so the upload is controlled. I know that some people will say, "well you can't automatize flash input so you don't need captcha in this situation" even though this is somewhat true, there is still screen macro programs that could potentially make the computer upload hundreds of pictures if there is not something in place to avoid it. I thought of implementing my own captcha but that seems to me like i would be reinventing the wheel, can anyone point me on the right track for this? or suggest another approach to avoid abuse on my image up-loader flash?

  • Telerik RadAjaxManager and Mouse Events in Chrome

    - by kuzco
    Whenever I'm using Telerik's RadAjaxManager in Chrome, the events sent to any mouse events I'm using are passed as null. For instance, the following: <img id="Image1" src="image.gif" onclick="alert(event)" /> <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> </AjaxSettings> </rad:RadAjaxManager> Alerts null when clicking the image. This does not happen in IE or FF. The version of the RadAjaxManager is 1.8.5.0. I'm guessing the problem does not occur in later versions, but an upgrade is not an option at the moment. I tried Telerik's support forum, but they didn't really provide any answer. What could cause such a problem? And how can it be dealt with?

  • Nav drop down with rounded corner troubles...

    - by Jonah1289
    Hi I have worked on the following nav drop down seen here http://charmcitykids.missionmedia.net/. It works and is almost complete, but I have one issue. When you mouseover a nav title the text goes from color to black and then shows the dropdown. That is how it should work, but when you move your mouse to go a nav title within the dropdown the black text(active image) goes back to color and doesnt remain black. Any suggestion when dropdown is active and user is navigating through such to keep the text(active image) black? thnx jonah

  • IOS where to put the configuration of facebook sdk

    - by Carol Smith
    I am trying to integrated my IOS 7 application with Facebook SDK I following this official tutorial https://developers.facebook.com/docs/ios/getting-started which states Configure the .plist Follow these three steps: Create a key called FacebookAppID with a string value, and add the app ID there. Create a key called FacebookDisplayName with a string value, and add the Display Name you configured in the App Dashboard. Create an array key called URL types with a single array sub-item called URL Schemes. Give this a single item with your app ID prefixed with fb. This is used to ensure the application will receive the callback URL of the web-based OAuth flow. The finished .plist should look something like this: My question is where to put these values? They already put this image, maybe it helps you to answer me Edit The problem that I don't have any plist file in my framework in xcode and I can't add a new one because if i did, I would have to add all the variables that you see in the image but the tutorial just stated about some of them

  • Issues loading Jquery (Galleria) script from inside an i-frame (beginner javascript?)

    - by 103188530284789248582
    Hello, first of all - I'm not entirely new to javascript, but am not fluent in it as I am with html and css, and am especially new to jQuery... so please excuse me if this questions seems easy or obvious, but after days of google I still have no solution to the problem... using jQuery 1.4.2.min, jQuery-ui-1.8.1 .... the site in question: http://homecapture.ca/sets/project_index.html The scenario: I have a tabbed menu generated from an unordered list, when a menu item is clicked it reveals an iframe which links to the page containing an image gallery. I am using jQuery UI tabs for the tabbed menu, and the galleries to which I'm linking are jQuery Galleria pages, automatically generated with Jalbum. The problem: The galleria plug-in only works normally from inside of the containing iframe in Chrome, has inconsistent behaviour in IE8 (seems to work in my local copy, but won't load properly online), and is not loaded properly in Firefox. Instead of displaying a thumbnail area and the first large image, the Galleria page shows the first thumbnail only, then when it is clicked the image it links to, but if you right-click and go Back, the iframe content shows up as a properly rendered Galleria page. Jalbum generates more script in the < head of the page in addition to linking to jquery and the galleria plug-in. All of it seems to be in charge of the gallery navigation , and I have relocated it to the < body of the page, in an effort to make it load after the parent page scripts, and together with the gallery content. At this point I am not sure what else I could do to solve the problem, without digging around in all or some of the library and pluging .js files (which I am not knowledgeable enough to do without some pointers). Has anyone dealt with a similar issue? I'm seeing some solutions for manipulating iframe content from a parent page with jQuery on here, is that what I should be researching instead? Thanks in advance for all the help! ps. I tried posting some code, but it seems I do not have enough 'reputation' for things to work right on here either :)

  • Jquery: How can I place triggers on images already cached?

    - by FLX
    Please see: hxxp://flx.me/h/0504/ Source: hxxp://pastebin.com/bDh5k3Qd jquery.preload-min.js: hxxp://jquery.com/plugins/project/Preload jquery.jplayer.min.js: hxxp://www.happyworm.com/jquery/jplayer/0.2.4/developer-guide.htm I'm using jquery.preload-min.js to preload images and to send a play trigger to jquery.jplayer.min.js to start playing a mp3 file. This works great when viewing the page for the first time (or force reloading all content). However, when the image has already been cached, it doesn't use the preloading script and thus does not send the play trigger to jplayer. How can I make it send a play trigger even when the image is cached? Thank you in advance, Dennis

  • Vibrations when exploding/repacking movie

    - by Stefano Borini
    Please bear with me, I know that what I'm doing can sound strange, but I can guarantee there's a very good reason for that. I took a movie with my camera, as avi. I imported the movie into iMovie and then exploded the single frames as PNG. Then I repacked these frames into mov using the following code movie, error = QTMovie.alloc().initToWritableFile_error_(out_path, None) mt = QTMakeTime(v, scale) attrib = {QTAddImageCodecType: "jpeg"} for path in png_paths: image = NSImage.alloc().initWithContentsOfFile_(path) movie.addImage_forDuration_withAttributes_(image, mt, attrib) movie.updateMovieFile() The resulting mov works, but it looks like the frames are "nervous" and shaky when compared to the original avi, which appears smoother. The size of the two files is approximately the same, and both the export and repacking occurred at 30 fps. The pics also appear to be aligned, so it's not due to accidental shift of the frames. My question is: by knowing the file formats and the process I performed, what is the probable cause of such result ? How can I fix it ?

  • Choosing between YUI Charts or Google Visualization API

    - by r2b2
    Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

  • OCR Web Service

    - by sdfx
    I am searching for an OCR web service (eventually open source, preferably free) that simply receives an image and returns the text of the image in writing. I've looked at tesseract, OCRopus and GOCR but the only open server I could find is WeOCR. Unfortunately the detection rates (at least during my tests) are sub-par and the speed is not much better. Does anyone have any experience with OCR web services? I guess the license of tesseract allows the operation of such a service, are there any out there?

  • Amazon S3 collisions with heroku and paperclip

    - by poseid
    I have an app on my localhost for development and an app for testing on heroku. Image upload with localhost and paperclip always works. However, doing the same experiment with image upload on my heroku app, the app hangs... and the upload seems to be going on forever. I suspect that there is a collision going on. What is needed to get but uploads working? Or do I need to use different buckets for each environment?

  • Release a retain UIImage property loaded via imageNamed?

    - by user158103
    In my class object i've defined a (nonatomic, retain) property for UIImage. I assigned this property with an image loaded via [UIImage imageNamed:@"file.png"]; If at some point I want to reassign this property to another image, should I have to release the prior reference? I am confused because by the retain property I know i should release it. But because imageNamed is a convenience method (does not use alloc), im not sure what rule to apply here. Thanks for the insight!

Everything seems to work except the code I put in italic.

  • 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

  • Another answer to the CAPTCHA problem?

    - by Xeoncross
    Most sites at least employ server access log checking and banning along with some kind of bot prevention measure like a CAPTCHA (those messed-up text images). The problem with CAPTCHAs is that they poss a threat to the user experience. Luckily they now come with user friendly features like refresh and audio versions. Anyway, like linux vs windows, it isn't worth the time of a spammer to customize and/or build a script to handle a custom CAPTCHA example that only pertains to one site. Therefore, I was wondering if there might be better ways to handle the whole CAPTCHA thing. In A Better CAPTCHA Peter Bromberg mentions that one way would be to convert the image to HTML and display it embedded in the page. On http://shiflett.org/ Chris simply asks users to type his name into an input. Examples like this are ways to simplifying the CAPTCHA experience while decreasing the value for spammers. Does anyone know of more good examples I could use or see any problem with the embedded image idea?

  • animate rotation

    - by Mike
    I'm trying to animate a rotation using CATransform3DMakeRotation, but the problem is once the animation is finished, the image goes back to its initial position, i.e back to zero. But I'd like to keep it where it finished rotating. How would I do that? edit What I'm trying to do is to create the same compass which comes with the new iPhone. Basically the locationmanager gives me new headings every few seconds (or several per second). Using the new heading and the timestamp, I was trying to get a smooth animation of the image but not getting anywhere. The only thing which seems to work is applying the transform directly, e.g. compassimage.layer.transform = CATransform3DMakeRotation(newHeading.trueHeading *M_PI/180,0,0,1.0): but that's not animated...

  • Drag Rotate UIImageView by touch

    - by rockstardev
    I have an UIImageView that is a subview of an UIView. I'm trying to create a drag rotate effect with the UIImageView similar to spinning a bottle but I'm having trouble calculating the radians to rotate the image by. My code below seems like it should work because I've seen a similar calculation in Flash examples. Can anyone shed some light on what I'm doing wrong? Thanks. This is the code contained in my image view subclass: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; lastLocation = [touch locationInView:[self superview]]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:[self superview]]; CGFloat xDisplacement = location.x - lastLocation.x; CGFloat yDisplacement = location.y - lastLocation.y; CGFloat rad = atan2f(yDisplacement,xDisplacement); self.transform = CGAffineTransformMakeRotation(rad); }
