  • Downloading image from server without file extension (NSData to UIImage)

    - by Msencenb
    From my server I'm pulling down a url that is supposed to simply be a profile image. The relevant code for pulling down the image from the urls is this: NSString *urlString = [NSString stringWithFormat:@"%@%@",kBaseURL,profile_image_url]; profilePic = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:urlString]]]; My url is in the format (note no file extension on the end since its dynamically rendered) localhost:8000/people/1/profile_image If I load the url in my browser the image displays; however the code above for pulling down the UIImage does not work. I've verified that the code does pull an image from a random site on the interwebs. Any thoughts on why this is happening?

  • Image impending other elements in iphone app view!

    - by wayne
    Hi. If someone could help I have a view in my iphone app with an image, a label and a button. I have positioned the image at the back however when I run the simulator the image is all that is showing. I have done exactly the same thing with other views and they work fine but can't get this one to work. I have checked that the image is "send to back" and other elements are at the front. Still no good. Any advice would be much appreciated. Thanks

  • [Android] How to launch an Activity without a UI?

    - by fjmustak
    Is it in any way possible to launch an activity from the main function without having a UI? i.e. is there a way to create a sort of "wrapper" around another activity, i.e. by launching the main activity, it takes you to another activity automatically. If that is not possible, is there a way to remove the main activity from the stack so that clicking the back button does not take you to a blank UI? Here's an example of what I'm trying to do: public class WrapperActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:555-1212")); startActivity(intent); } }

  • What's best performance way to constantly change image on WP7?

    - by AlRodriguez
    I'm trying to make my own type of remote desktop for WP7. I have a WCF service that returns an image on what's on the target machine's screen. Here's the WCF Server Code: // Method to load desktop image Bitmap image = new Bitmap( ViewSize.Width, ViewSize.Height ); Graphics g = Graphics.FromImage( image ); g.CopyFromScreen( Position.X, Position.Y, 0, 0, ViewSize ); g.Dispose( ); return image; // Convert image to byte[] which is returned to client using ( MemoryStream ms = new MemoryStream( ) ) { Bitmap image = screenGrabber.LoadScreenImage( ); image.Save( ms, ImageFormat.Jpeg ); imageArray = ms.ToArray( ); } Here's the code for the WP7 client: MemoryStream stream = new MemoryStream( data ); BitmapImage image = new BitmapImage( ); image.SetSource( stream ); BackgroundImage.Source = image; The BackgroundImage variable is an Image control. I'm noticing this freeze on the emulator after a short while, and will eventually crash from an OutOfMemoryException. This is already pretty slow ( images show up a good half second later than what's on the screen ), and I'm wondering if there's a better/faster way of doing this? Any help would be great. Thanks in advance.

  • Dynamic Image Caching with Java

    - by zteater
    I have a servlet with an API that delivers images from GET requests. The servlet creates a data file of CAD commands based on the parameters of the GET request. This data file is then delivered to an image parser, which creates an image on the file system. The servlet reads the image and returns the bytes on the response. All of the IO and the calling of the image parser program can be very taxing and images of around 80kb are rendering in 3-4000ms on a local system. There are roughly 20 parameters that make up the GET request. Each correlates to a different portion of the image. So, the combinations of possible images is extremely large. To alleviate the loading time, I plan to store BLOBs of rendered images in a database. If a GET request matches one previously executed, I will pull from cache. Else, I will render a new one. This does not fix "first-time" run, but will help "n+1 runs". Any other ideas on how I can improve performance?

  • Why is my input textbox extending outside margins in BlackBerry and Android, but not iOS?

    - by Dallas
    I have an input field that is extending well beyond the rest of the page, but as the question alludes to, it appears fine in iOS. I am wondering if anyone has run into this issue. My search button, which in iOS is on the right of the search textbox, actually wraps to the next "line" on the other two platforms. I am not using a table, just inside a div, and the CSS isn't doing anything fancy. Any ideas?

  • ScrollBall press events while screen is off on an Android device.

    - by stolksdorf
    I'm writing a quick music player for myself on my Nexus One and really want to add the feature of being able to switch to the next song without removing it from it's case, ie. by pressing the scrollball through the sleeve. I've scoured many resources and... Haven't found a decently easy way to listen to key press events while the screen is off. Can't seem to even get scrollball press events to work. I've tried using a broadcastreciever listening for the Dpad_center intent, but it doesn't seem to function properly. I'm not looking for someone to write the code for me, but if you have successfully done either of these things, any insight on techniques or resources would be amazing. Thanks in advance!

  • How to give credit about an image I display in my website?

    - by Erel Segal Halevi
    I looked for an image for decorating the main page of my website. I found a great image in Wikipedia. The license allows me to use the image, but, I must give credit to the creators (which includes their name and a link to their Flickr page). My question is: what is the best way to give credit about the image, such that the page design will not be harmed? In case it matters: my page is very simple - it contains only the image (floated right), a heading, a small amount of text, and some links. But, my question is more general and probably applies to many different websites.

  • How to spawn a character at certain point and walk to a set point

    - by Robert H.
    I am making a game where I have a background image of a neighborhood. Each location has a different number of customers that are generated to walk on sidewalks. They all walk to a specific location (like a stand or cart that sells stuff), after they get to location I want them to interact with the cart. However, if another customer is already in a sale interaction then the others get in line in order of arrival. After the transaction the customers walk off screen. Any information on how I can do this and what game engine would be needed? Any one have any idea where I should go for this. I already have my game done up through Eclipse/Java without any game engine.

  • Physics don't apply on a unique body AndEngine

    - by Kanga
    I am developing a game in AndEngine so far I managed to create everything I wanted for my sprite that was connected to a BoxBody. I was rotating it moving it everything was great. I wanted my collision detection to be more precise so I changed from boxBody to unique irregular shaped body. I found all the vertices and I just replaced the newly created irregular shaped body with the boxbody everywhere in my code. Not only that the image of the sprite is not in place but all the physics and maths I was doing for movement and physics wont work. Please help me :(. Thanks in advance.
