  • CGImageCreateWithMask with an image as a mask

    - by Peyman
    Hi I am trying to use an image (painted as Core Graphics) to create a mask. What I am doing is this 1. creating a Core Graphics path CGContextSaveGState(context); CGContextBeginPath(context); CGContextMoveToPoint(context,circleCenter.x,circleCenter.y); //CGContextSetAllowsAntialiasing(myBitmapContext, YES); CGContextAddArc(context,circleCenter.x, circleCenter.y,circleRadius,startingAngle, endingAngle, 0); // 0 is counterclockwise CGContextClosePath(context); CGContextSetRGBStrokeColor(context,1.0,0.0,0.0,1.0); CGContextSetRGBFillColor(context,1.0,0.0,0.0,0.2); CGContextDrawPath(context, kCGPathFillStroke); 2. then I'm saving the context that has the path just painted CGImageRef pacmanImage = CGBitmapContextCreateImage (context); 3. restoring the context CGContextRestoreGState(context); CGContextSaveGState(context); 4. creating a 1 bit mask (which will provide the black-white mask) bitsPerComponent = 1; bitsPerPixel = bitsPerComponent * 1 ; bytesPerRow = (CGImageGetWidth(imgToMaskRef) * bitsPerPixel); mask = CGImageCreate(CGImageGetWidth(imgToMaskRef), CGImageGetHeight(imgToMaskRef), bitsPerComponent, bitsPerPixel, bytesPerRow, greyColorSpace, kCGImageAlphaNone, CGImageGetDataProvider(pacmanImage), NULL, //decode YES, //shouldInterpolate kCGRenderingIntentDefault); 5. masking the imgToMaskRef (which is a CGImageRef imgToMaskRef =imgToMask.CGImage;) with the mask just created imageMaskedWithImage = CGImageCreateWithMask(imgToMaskRef, mask); CGContextDrawImage(context,imgRectBox, imageMaskedWithImage); CGImageRef maskedImageFinal = CGBitmapContextCreateImage (context); returning the maskedImageFinal to the caller of this method (as wheelChoiceMadeState, which is a CGImageRef) who then updates the CALayer contents property with the image theLayer.contents = (id) wheelChoiceMadeState; the problem I am seeing is that the mask does not work properly and looks very strange indeed. I get strange patterns across the path painted by the Core Graphics. My hunch is there is something with CGImageGetDataProvider() but I am not sure. Any help would be appreciated thank you

  • Disk2VHD image used in Win 7 as a bootable VPC

    - by John
    I have used Disk2VHD to create a VHD of my old XP Laptop's boot drive. I would like to use it as an XP virtual machine on my new Win7 machine. I have tried doingit on a second XP machine and the VPC boots properly using that VHD but under Win7 I can't get it to act as the boot disk for the VPC. Any ideas? TIA J

  • Looking For a .NET Task Scheduling library

    - by Hounshell
    I'm looking for the following features: Scheduler uses SQL Server as the backing store Tasks can be scheduled by one application and executed by another I can have multiple applications, each of which handles a specific subset of tasks Tasks can be triggered at specific times, now, or based on the success or failure of other tasks Data can be attached to tasks There are a number of nice-to-have's, like a web management console, clustering/failover support, customizable logging, but they're not requirements. On the surface Quartz.NET has a nice interface and seems to fit the bill as it satisfies (1), (4 with some custom work) and (5), but I've been beating my head against (2) and (3) seems like I'd have to invest more effort than it's worth, especially given how convoluted the innards of it are. Any other libraries out there? Open source is preferred, with free as a close runner up. It's really hard to get management to pay for things like this when it's not their idea.

  • Differences between AForge and OpenCV

    - by vrish88
    Hello, I am just learning about computer vision and C#. It seems like two prominent image processing libraries are OpenCV and AForge. What are some of the differences of the two? I am making a basic image editor in C# and while researching I have come across articles on both. But I don't really know why I would choose one over the other. I would like to eventually improve the app to include more advanced functions. Thanks.

  • Fix common library functions, or abandon then?

    - by Ian Boyd
    Imagine i have a function with a bug in it: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } So the call: MakeLocation("Springfield", "MO"); would return "Springfield, MO" Now there's a slight problem, what if the user called: MakeLocation("Springfield, MO", "OH"); The called it wrong, obviously. But the function would return "Springfield, MO, OH". The system was functioning like this for many years, until i noticed the function being used wrong, and i corrected it. And i also updated the original function to catch such an obvious mistake - in case it's happening elsewhere: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } And testing showed the problem fixed. Except we missed an edge case, and the customer found it. So now the moral dillema. Do you ever add new sanity checks, safety checks, assertions to exising code? Or do you call the old function abandoned, and have a new one: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } Boolean MakeLocation2(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } The same can apply for anything: Question FetchQuestion(Int id) { if (id == 0) throw new EFetchQuestionException("No question ID specified"); ... } Do you risk breaking existing code, at the expense of existing code being wrong?

  • Change the contrast of Image like Adobe Photoshop in ASP.net C#

    - by Hoque
    While I was trying to change the brightness and contrast of Image using C#, but I could not get success in changing the contrast of the Image. May I expect any support from here. I am using ColorMatrix to do that. Here are the code that I am using for brightness(works fine) and contrast(does not work properly). public static ColorMatrix CreateBrightnessMatrix(float Brightness) { if (Brightness < -1 || Brightness > 1) throw new ArgumentOutOfRangeException("Brightness value is out of range"); ColorMatrix cm = new ColorMatrix(new float[][]{ new float[] { 1f, 0, 0, 0, 0}, new float[] { 0, 1f, 0, 0, 0}, new float[] { 0, 0, 1f, 0, 0}, new float[] { 0, 0, 0, 1f, 0}, new float[] {Brightness, Brightness, Brightness, 1f, 1f}}); return cm; } public static ColorMatrix CreateContrastMatrix(float Contrast) { if (Contrast < 0 || Contrast > 3) throw new ArgumentOutOfRangeException("Contrast value is out of range"); float Trans = (1f - Contrast) / 2f; ColorMatrix cm = new ColorMatrix(new float[][]{ new float[] {Contrast, 0f, 0f, 0f, 0f}, new float[] { 0f, Contrast, 0f, 0f, 0f}, new float[] { 0f, 0f, Contrast, 0f, 0f}, new float[] { 0f, 0f, 0f, 1f, 0f}, new float[] { Trans, Trans, Trans, 0f, 1f}}); return cm; } Thanks.

  • How to setup ASP.NET Ajax Library and WCF Data Services

    - by Jronny
    I was following http://msdn.microsoft.com/en-us/magazine/ee336022.aspx but there were js errors. for example Sys is undefined So I added http://ajax.microsoft.com/ajax/act/40412/start.js. Then Sys.Data is undefined So I added http://ajax.microsoft.com/ajax/act/40412/MicrosoftAjaxDataContext.debug.js. But then TypeError: Sys.Data.OpenDataContext is not a constructor What shall I do to be able to call the service the way they do it on the first link? What are the scripts and resources needed? Thanks a lot.

  • CherryPy sessions for same domain, different port

    - by detly
    Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

  • saving WPF InkCanvas to a JPG - image is getting cropped

    - by Jason
    I have a WPF InkCanvas control I'm using to capture a signature in my application. The control looks like this - it's 700x300 However, when I save it as a JPG, the resulting image looks like this, also 700x300 The code I'm using to save sigPath = System.IO.Path.GetTempFileName(); MemoryStream ms = new MemoryStream(); FileStream fs = new FileStream(sigPath, FileMode.Create); RenderTargetBitmap rtb = new RenderTargetBitmap((int)inkSig.Width, (int)inkSig.Height, 96d, 96d, PixelFormats.Default); rtb.Render(inkSig); JpegBitmapEncoder encoder = new JpegBitmapEncoder(); encoder.Frames.Add(BitmapFrame.Create(rtb)); encoder.Save(fs); fs.Close(); This is the XAML I'm using: <Window x:Class="Consent.Client.SigPanel" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Background="Transparent" Topmost="True" AllowsTransparency="True" Title="SigPanel" Left="0" Top="0" Height="1024" Width="768" WindowStyle ="None" ShowInTaskbar="False" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" > <Border BorderThickness="1" BorderBrush="Black" Background='#FFFFFFFF' x:Name='DocumentRoot' Width='750' Height='400' CornerRadius='10'> <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center"> <TextBlock Name="txtLabel" FontSize="24" HorizontalAlignment="Center" >Label</TextBlock> <InkCanvas Opacity="1" Background="Beige" Name="inkSig" Width="700" Height="300" /> <StackPanel HorizontalAlignment="Center" Orientation="Horizontal"> <Button FontSize="24" Margin="10" Width="150" Name="btnSave" Click="btnSave_Click">Save</Button> <Button FontSize="24" Margin="10" Width="150" Name="btnCancel" Click="btnCancel_Click">Cancel</Button> <Button FontSize="24" Margin="10" Width="150" Name="btnClear" Click="btnClear_Click">Clear</Button> </StackPanel> </StackPanel> </Border> In the past this worked perfectly. I can't figure out what changed that is causing the image to shift when it is saved.

  • Asp.net ajax library preview 6 (Ajax toolkits inside a dataview)

    - by Thurein
    Hi, I was using the sys.ui.dataview, ado.net data services and a html page to provide an edit page. It was working fine, but when I wanted to apply some ACT features, for instance watermark or autocomplete on a textbox (input) within the dataview div, its not applied. However, when I move that text box, out of the div, it is working fine and the watermark effect was applied. Am I doing something wrong or any advice ? Thanks

  • CSS: Horizontally scrolling image inside variable width div?

    - by neezer
    I have... <div id="tabs"> <!-- ... --> <div id="interior-photo"> <img src="..."> </div> <!-- ... --> </div> ... and ... #interior-photo { overflow-x: auto; } Basically, I have a page broken down into a main section and a fixed-width right sidebar. Within the main section, I have my tabbed div. The entire page grows with the width of the window, so when the window is resized, the tabbed div grows horizontally in size too. My problem is that the image that I'm loading inside one of the tabbed divs is generally much, much wider than the window usually is (they're panorama pictures; very lengthy horizontally, but not much vertically). I know that I can force the contents of #interior-photo to scroll horizontally using the CSS rule above, but that only seems to work when that same div has a fixed width. Since I want that div to have a variable width, it always seems to display the full width of the image, pushing my layout way out of whack. I know how to fix this using Javascript, but I was wondering if anyone has a CSS-only solution. If you need more information about my layout to solve this issue, please let me know. Thanks!

  • displaying images in a list box so the image resizes based on parent container

  • linking to boost regex in gcc

    - by rboorgapally
    i am trying to compile my program which uses regex on linux. I built the boost library in the libs/regex/build by typing make -fgcc.mak which created a directory gcc which contains the following four files boost_regex-gcc-1_35 boost_regex-gcc-d-1_35 libboost_regex-gcc-1_35.a libboost_regex-gcc-d-1_35.a Now I want to use regex from my program which is in some arbitrary directory. I #included boost/regex.hpp I got the error which stated that regex.hpp is not found. Then I gave the -I option in the g++ compiler. I didn't get that error. But I get the following error undefined reference to `boost::re_detail::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > > >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)' I googled and found that I need to somehow link one of the above 4 libraries to my program. How can I do it. Which one should I link and why?

  • Using DevIL with Xcode

    - by jak3t
    Hello everyone! I'm trying to use DevIL with XCode but I can't get it to work. I tried using the "standard" method by doing "configure make make install" and using #import <IL/il> but it doesn't work. It identifies the library but I still get some compiling errors: Ld build/Release/cg.app/Contents/MacOS/cg normal i386 cd "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1" /Developer/usr/bin/g++-4.2 -arch i386 "-L/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release" "-F/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release" -filelist "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/CGaula1.build/Release/cg.build/Objects-normal/i386/cg.LinkFileList" -framework Foundation -framework AppKit -framework GLUT -framework OpenGL -framework Cocoa -framework AppKit -o "/Users/simaorfreitas/Documents/LESI/3º ano/CG/CGaula1/build/Release/cg.app/Contents/MacOS/cg" Undefined symbols: "_ilConvertImage", referenced from: terreno() in main.o "_ilGetInteger", referenced from: terreno() in main.o terreno() in main.o terreno() in main.o "_ilLoadImage", referenced from: terreno() in main.o "_ilBindImage", referenced from: terreno() in main.o "_ilGetData", referenced from: terreno() in main.o "_ilInit", referenced from: terreno() in main.o "_ilGenImages", referenced from: terreno() in main.o ld: symbol(s) not found collect2: ld returned 1 exit status` So i tried do it by using the macports libdevil install. It installed correctly but nothing seems to work. Do I need to change my #import declarations? Any suggestion to install DevIL on the Mac correctly and use it in a XCode Project? Thanks a lot!

  • Extracting URIs from RDF web page in Java using Jena Library

  • latex tabular vertical alignment to top?

    - by shoosh
    I'm trying to create a simple tabular with two cells of text and two images below them like so: \begin{tabular}[h]{ c | c} \emph{Normal} & \emph{Cone} \\ \includegraphics[width=0.39\textwidth]{images/pipe1} & \includegraphics[width=0.61\textwidth]{images/pipe2} \end{tabular} The first image is shorter than the second and I want it to be aligned at the top of the cell but for some reason it gets aligned to the bottom of the cell instead. I've tried using the array package and do this: \begin{tabular}[h]{ p{0.39\textwidth} | p{0.61\textwidth} } \emph{Normal} & \emph{Cone} \\ \includegraphics[width=0.39\textwidth]{images/pipe1} & \includegraphics[width=0.61\textwidth]{images/pipe2} \end{tabular} But this doesn't change anything. The first image is still aligned to the bottom. Why is that? Could there be something else going on which forces the alignment to stick to the bottom?

    - by azamsharp
    One again Microsoft poor documentation has left me confused. I am trying to use the new features of the .NET 4.0 framework. I am using the following code to populate the Title and Director but it keeps getting blank. <script language="javascript" type="text/javascript"> Sys.require([Sys.components.dataView, Sys.components.dataContext,Sys.scripts.WebServices], function () { Sys.create.dataView("#moviesView", { dataProvider: "MovieService.svc", fetchOperation: "GetMovies", autoFetch: true }); }); </script> And here it the HTML code: <ul id="moviesView"> <li> {{Title}} - {{Director}} </li> </ul> IS THIS THE LATEST URL TO Start.js file. Here is the Ajax-Enabled WCF Service: [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class MovieService { [OperationContract] public Movie GetMovies() { return new Movie() { Title = "SS", Director = "SSSSS" }; } } [DataContract] public class Movie { [DataMember] public string Title { get; set; } [DataMember] public string Director { get; set; } }

  • How do I pass a lot of parameters to views in Django?

    - by Mark
    I'm very new to Django and I'm trying to build an application to present my data in tables and charts. Till now my learning process went very smooth, but now I'm a bit stuck. My pageview retrieves large amounts of data from a database and puts it in the context. The template then generates different html-tables. So far so good. Now I want to add different charts to the template. I manage to do this by defining <img src=".../> tags. The Matplotlib chart is generate in my chartview an returned via: response=HttpResponse(content_type='image/png') canvas.print_png(response) return response Now I have different questions: the data is retrieved twice from the database. Once in the pageview to render the tables, and again in the chartview for making the charts. What is the best way to pass the data, already in the context of the page to the chartview? I need a lot of charts, each with different datasets. I could make a chartview for each chart, but probably there is a better way. How do I pass the different dataset names to the chartview? Some charts have 20 datasets, so I don't think that passing these dataset parameters via the url (like: <imgm src="chart/dataset1/dataset2/.../dataset20/chart.png />) is the right way. Any advice?

  • How to restore a VirtualBox image given the .vdi file

    - by Ramon Tayag
    Background I have VirtualBox on Linux and recently the drive with the system files failed on me. I'm able to use the Live CD to view the files of the storage drive, and through this, I can copy my data files to another computer while I work on this one. How do I load the .vdi in another computer (or in this case, the fresh install of Ubuntu)? I see many samples online of how to export it, but it assumes the host is currently working. Thanks!

  • PHP - How to use Php inside Php?

    - by Dodi300
    Hello. Can someone tell/show me how to use PHP inside PHP. I'm trying to make the URL of an image change depending on what value is in a MySQL database. Here's an example of what I'm trying to do. Bear in mind that $idx already has a value from the URL of the page. <?php $query = "SELECT * FROM comment WHERE uname='$idx'"; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "<img src='' name='comm' width='75px' height='60px' id='mainimage' />"; } ?> How would I make the source value, for the image, come from a different table?
