  • Removing the transparency from image while keeping the actual image

    - by KPL
    Hello people, I have three images,and , they are not square or rectangular in shape. They are just like face of anyone. So, basically, my images are in the size 196x196 or anything like that, but complete square or rectangle with the face in the middle and transperant background in the rest of the portion. Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question.

  • Configuring web.xml for webservices and servlet.

    - by Win Man
    Hi, I am new to Restlets. Trying to configure the web.xml (on JBoss). I have 2 entries, one for a servlet (got nothing to do with webservices) other for webservices, using Restlet. Here are the entries.. <servlet> <servlet-name>AuthenticationServlet</servlet-name> <servlet-class>com.safeid.web.server.api.servlet.AuthenticationServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>AuthenticationServlet</servlet-name> <url-pattern>/authenticate/*</url-pattern> </servlet-mapping> <!-- Start of Entries for the REST Web Services. --> <context-param> <param-name>org.restlet.application</param-name> <param-value>com.safeid.web.server.SafeIDRouterApplication</param-value> </context-param> <servlet> <servlet-name>RestletServlet</servlet-name> <servlet-class>com.noelios.restlet.ext.servlet.ServerServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>RestletServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <!-- END of Entries for the REST Web Services.--> Both don't work together. In the above setup the Restlet works. However when I change the RestletServlet /* to something like <servlet-mapping> <servlet-name>RestletServlet</servlet-name> <url-pattern>/credential/*</url-pattern> </servlet-mapping> the Restlet stop working and the AuthenticationServlet works fine. What am I missing here?

    - by John Mee
    Can anyone tell me the .hgignore pattern to track one specific file in a directory and to ignore everything else? I have a "media" directory which contains a "default.png", for obvious purposes, and the rest of the directory will hold user media. We want hg to ignore everything in the media directory excepting the default file.

  • How to use multi-level SUBDIRS in Makefile.am:s?

    - by Jukka Dahlbom
    A common issue automake complains about is caused by following lines in various Makefile.am:s Makefile.am: SUBDIRS = deployment transport/http/util transport/http/common engine transport The intent of this line is to force the order of building so that transport/http/util and transport/http/common are build before the engine directory, and building rest of the transport after engine is build. This line causes the following error when running automake under MinGW: Makefile.am:1: directory should not contain `/'

  • Moving files between Windows computers without creating network shares

    - by mavnn
    What's needed: To move several directories between two Windows 2008 servers on a regular basis. Due to security requirements, neither server is supposed to have network shares set up or extraneous software installed. What's available: Administrator access to both machines (including remote desktop access if that helps). A third machine with: Visual Studio 2010 Cygwin Bonus extras The script that does the rest of the work (apart from moving the files) is currently written in F#, but any .net/command line based solution would be fine.

  • resttemplate getForObject map responsetype

    - by Zack Macomber
    I'm invoking a rest service that returns JSON like this: { "some.key" : "some value", "another.key" : "another value" } I would like to think that I can invoke this service with a java.util.Map as the response type but that's not working for me. I get this exception: org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [interface java.util.Map] Should I just specify String as the response type and convert the JSON to a Map?

  • I need a way to not rotate a subview when the parent view rotates

    - by jmurphy
    Hello, I have a situation where I have a view, and several subviews, and the view and all but one of its subviews are expected to rotate. The one subview that I don't want to rotate is a UIImageView and the image gets distorted when I rotate so I need it to simply not rotate when the rest of the views components rotate. Does anybody know of a way to achieve this? Is there some excludeFromRotating property I've overlooked? Thanks!

  • Java and C++ on Stack Unwinding issue

    - by sahs-i-muhterem
    As far as I know, in case of an uncaught exception, C++ destroys the local variables immediately, Java releases the references and leaves the rest for the garbage collector. Is this right? What exactly is the difference between Java and C++ on this issue? in other words, which of these two languages is considered better in terms of stack unwinding issue? :)

  • Why do browsers use my saved password for all forms in the one site?

    - by user313272
    Is there a way to limit the url of saved credentials in browsers? For example, if I save a username and password for http://www.website.com/login can I make it so that the rest of the forms in the site don't use these details? http://www.website.com/members, http://www.website.com/admin etc... I'm aware of the autocomplete attribute but I don't want to turn off autocomplete entirely. I would like it if the browser remembered the login details per form or url.

  • Custom language - FOR loop in a clojure interpeter?

    - by Mark
    I have a basic interpreter in clojure. Now i need to implement for (initialisation; finish-test; loop-update) { statements } Implement a similar for-loop for the interpreted language. The pattern will be: (for variable-declarations end-test loop-update do statement) The variable-declarations will set up initial values for variables.The end-test returns a boolean, and the loop will end if end-test returns false. The statement is interpreted followed by the loop-update for each pass of the loop. Examples of use are: (run ’(for ((i 0)) (< i 10) (set i (+ 1 i)) do (println i))) (run ’(for ((i 0) (j 0)) (< i 10) (seq (set i (+ 1 i)) (set j (+ j (* 2 i)))) do (println j))) inside my interpreter. I will attach my interpreter code I got so far. Any help is appreciated.
