  • iPhone zoom to userLocation

    - by Taylor Satula
    Hi, I need help making my iPhone app zoom to the users current location. I have seen this answered before on StackOverflow ( http://stackoverflow.com/questions/2423236/zoom-on-userlocation )but I have no idea what I am doing when it comes to iPhone development (I make websites not iPhone apps). I need it explained extremely simply, down to where the code snippets go starting from a blank project. Any help is very much appreciated. -- Taylor

  • Calling Browser Zoom

    - by ThePower
    Hi, I would like to provide two buttons that will zoom in and out in my silverlight application. Basically, I would like them to do exactly the same as clicking Zoom In and Out via the browser. (Or holding CTRL and scrolling the mouse wheel). Is there an easy way to do this or will it be easier to use Scaling? Regards, Lloyd

  • SilverLight 3 Beginner question: Scroll with mousewheel and zoom image with panning

    - by JP Hellemons
    Hello, I would like to make a small silverlight app which displays one fairly large image which can be zoomed in by scrolling the mouse and then panned with the mouse. it's similar to the function in google maps and i do not want to use deepzoom. here is what i have at the moment. please keep in mind that this is my first silverlight app: this app is just for me to see it's a good way to build in a website. so it's a demo app and therefor has bad variable names. the initial image is 1800px width. private void sc_MouseWheel(object sender, MouseWheelEventArgs e) { var st = (ScaleTransform)plaatje.RenderTransform; double zoom = e.Delta > 0 ? .1 : -.1; st.ScaleX += zoom; st.ScaleY += zoom; } this works, but could use some smoothing and it's positioned top left and not centered. the panning is like this: found it @ http://stackoverflow.com/questions/741956/wpf-pan-zoom-image and converted it to this below to work in silverlight Point start; Point origin; bool captured = false; private void plaatje_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { plaatje.CaptureMouse(); captured = true; var tt = (TranslateTransform)((TransformGroup)plaatje.RenderTransform) .Children.First(tr => tr is TranslateTransform); start = e.GetPosition(canvasje); origin = new Point(tt.X, tt.Y); } private void plaatje_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { plaatje.ReleaseMouseCapture(); captured = false; } private void plaatje_MouseMove(object sender, MouseEventArgs e) { if (!captured) return; var tt = (TranslateTransform)((TransformGroup)plaatje.RenderTransform).Children.First(tr => tr is TranslateTransform); double xVerschuiving = start.X - e.GetPosition(canvasje).X; double yVerschuiving = start.Y - e.GetPosition(canvasje).Y; tt.X = origin.X - xVerschuiving; tt.Y = origin.Y - yVerschuiving; } so the scaling isn't smooth and the panning isn't working, because when i click it, the image disappears. thanks in advanced!

  • Image control with pan and zoom ability

    - by corvus
    I am looking for a free .net winforms control which is able to display images. PictureBox isn't a solution because you have to implement all pan&zoom events yourself. The control should be able to display images like 4000x5000 pixels, have zoom and pan buttons.

  • Eclipse Package Explorer Zoom?

    - by british_trader
    Configuring Eclipse to look exactly how you want is a tough job I've found, therefore I'm not going to attempt to do this myself. I'd like to 'zoom out' of the Package Explorer side bar? You see, I like only having my code on the screen with a small section for the files in the project - however I can never see the full path of the file or package I'm currently in because of this. Is there a way to keep the 'main screen' normal, but zoom out of the Package Explorer by about 50%?

  • Is it possible to transcode audio in C# using DirectSound?

    - by Robert Davis
    I want to transcode a lot of audio from its source format to PCM without resampling or messing with the sample size. I figure if Windows Media Player can play the file and it doesn't use a legacy ACM codecs it must be using DirectSound to do so (this is on Windows XP and Windows Server 2k3). So is it possible to access DirectSound from C# and do so? I've tried searching the web but all the examples have been about playback which I have no interest in doing.

  • What's the best way of playing media files (esp. audio) with Mono/C#?

    - by supercheetah
    I'm trying to create something that will be playing some sound and music for some things in Mono+C#, but I'm not sure what the best thing will be for that. I'm trying to make it usable with things like Ogg Vorbis, MP3s, and wave files. My primary platform will be Linux, although a cross platform solution would be nice. Anyone have any suggestions for libraries for playing audio files?

  • Where can I get a splitter to connect a device with a single 3.5 mm plug into the audio input/output jacks on my laptop?

    - by XinJeisan
    I recently bought the :Hype Retro Handset for Mobile Phone" -- its just a device that looks like a handset to use when chatting on a computer or mobile phone that plugs into the phone/computer with a single 3.5 mm plug. I was hoping to use it on my windows 7 Toshiba laptop. I can hear audio fine through the handset but what I'm saying is not being picked up on the handset. On the box it says "some phones and computers may need additional adapters," so I'm hoping it is possible to get a splitter or something for this to work properly. I did email the parent company (http://dglusa.com/) but I haven't heard from them, and, looking over their website, I doubt I will. I also went to the local radio shack, and the guy said I needed a splitter, but he didn't know where to get one. I can find the kind of splitter I think I need online, but I'm unsure whether they are just for output or can also do input/output.

  • Flash in browsers does not play sound accurately using Pulse network audio

    - by Dave M G
    I use PulseAudio to send sound over the LAN to an audio server. When playing any Flash media in Firefox or Chrome, the sound flutters, as if the volume were going up and down every second. The problem does not exhibit with any other software, and I think it's specific to how Flash interacts with my sound set up. How do I get Flash to play nice with the PulseAudio network sound server? Update I have discovered that I can stop the sound fluttering if I follow these steps: Start a Flash video Run pulseaudio --kill on the server Wait about 7 seconds After this, the PulseAudio server automatically respawns, and the sound in the Flash video is perfect. The problem now, though, is that I have to do this every time I start a Flash video. This is obviously not desireable. So, the question is, how do I make whatever it is that makes the sound work when I go through these steps stick so that I don't have to do them? Also, I've uploaded some PulseAudio log output to Pastebin, taken while attempting to play a Flash video, if that helps. I've tried to get logging details from Flash, but despite installing and enabling Flash for debugging, it has not generated any ouput at all. Details I have uploaded an example video of the problem onto Youtube. In the video you can see the opening of a Ted Talk video, and the sound flutters as it plays. The video also stutters while playing back. Here are my sound device output settings:

  • Double audio cd ripping weirdness

    - by jqno
    Since I installed Ubuntu 12.04, Rhythmbox, Banshee and Sound Juicer have started acting weird around double cd's, and specifically, cd #2 of said double cd. Sometimes, they will show the information of cd #1. Track names, durations, and even count are incorrect. Sometimes, they will first show the tracks for cd #1, then continue onto cd #2 if cd #2 has more tracks than #1. Sound Juicer seems to be unable to find any track durations at all, even for single cd's. Obviously, this is a pain when I'm trying to rip double cd's. And I have a fair number of them, which I want to rip. This happens on both my machines (a slightly aging iMac, and a 1-year-old Sony Vaio). However, on previous versions of Ubuntu, this never happened. All on the same machines. So I suspect 12.04 is using a different lib for extracting audio cd data. Just for kicks, I tried with Linux Mint 13, and there it works correctly, even though it claims to be based on Ubuntu 12.04 and therefore should be using (partially) the same software. So if the Mint guys can fix it, I should be able to do it too, right? So, my question: what changed in 12.04 that could cause this? And more importantly: what can I do to fix it?

  • How to make pulseaudio and ubuntu detect the same audio device as alsa driver

    - by Kiwy
    I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.
