How to getColor at specific Coord in Canvas?? thx

I am programming a little worm game and am very newby.. please help me with this:
i want to know if the color at a special coordinate is possible to receive. i could not find a proper method in java language. you can only get the general background or foreground color of the whole canvas for example. i only need the color of one point of the canvas. how can i do that??
please help..
mfg, new programmer in need

Look up the BufferedImage class, once you�ve got it set up you can getRGB(x,y) and setRGB(x,y, int), the color returned by get is a packed aRGB int.
Image loadpic = getImage(getDocumentBase(), "test.jpg");
BufferedImage bi = new BufferedImage(width,height,BufferedImage.TYPE_INT_RGB); //there are 13 TYPEs look them up.
Graphics  offG = bi.createGraphics();
//then in paint 
paint(Graphics g)
g.drawImage(bi,0,0,this);
//or to draw on the BufferedImage
offG.drawImage(loadpic,0,0,this);

  • Need Color from specific coord in canvas! plz help

    not much more to say.. im a bloody newbie and cant seem to find the proper method to get the color of a single point in a canvas. thx very much for trying to help me..

    If you have a new class extending Canvas, overide the paint method:
    public void paint(Graphics g)
        g.setColor(Color.red);
        g.fillRect(30,30,1,1);         //  a red dot
    }

  • How to set a specific width to all the TextInputs used in a mxml file on its creation complete?

    How to set a specific width to all the TextInputs used in a mxml file on its creation complete?

    Hi subhajit nag,
    I think the best approach would what I say is if you can make use of a Global variable or using a Singleton class having a variable which can be accessed globally through out the application.
    Below is the sample what I am talking to:
    So in below example you can access the variables textInputWidth and textInputHeight globally throghout the application since you have decalred them in main mxml file.
    You can access these variabled in another mxml file as Application.application.textInputWidth and Application.application.textInputHeight. So if at all you are required to modify these values you are only required to modify at a single place in main mxml file..thats it.
    If you are use any Singleton classes like ModelLocator you can place these variables in this class and refer from that class.
    Hope this resoved your problem..
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical">
    <mx:Script>
      <![CDATA[
       [Bindable]private var textInputWidth:int = 250;
       [Bindable]private var textInputHeight:int = 25;
      ]]>
    </mx:Script>
    <mx:Canvas id="canvas1">
      <mx:TextInput id="txt1" width="{textInputWidth}" height="{textInputHeight}"/> 
    </mx:Canvas>
    <mx:Canvas id="canvas2">
      <mx:TextInput id="txt2" width="{textInputWidth}" height="{textInputHeight}"/> 
    </mx:Canvas>
    <mx:Canvas id="canvas3">
      <mx:TextInput id="txt3" width="{textInputWidth}" height="{textInputHeight}"/> 
    </mx:Canvas>
    <mx:TextInput id="txt4" width="{textInputWidth}" height="{textInputHeight}"/>
    <mx:TextInput id="txt5" width="{textInputWidth}" height="{textInputHeight}"/>

  • How to monitor a specific transaction in Solution Manager ?

    Hi all,
    I have configured the Service Level Reporting and it works correctly.
    But i don't know how to monitor a specific transaction like SM21, DB02, FB01N etc... ?
    In the SL Reports configuration steps, we can configure this option : Select Business Processes For SL Report. I did a lot of tests but it does not work.
    Have i to configure the Business Process Monitoring ?
    Thanks.

    Hello,
    it depends a little on what you want to do. If you use the pure CCMS monitoring with the table ALTRAMONI you get average response time per instance and you only get new measurements once the status changes from green to yellow or red.
    In order to get continuous measurements you should look into Business Process Monitoring and the different documentations under https://service.sap.com/bpm --> Media Libary --> Technical Information. E.g. the PDF Setup Guide for Application Monitoring describes this "newer" dialog performance monitor. Probably you have to click on the calendar sheet in the Media Libary to also see older documents as well. As the Business Process Monitoring integrates with BW (there is also a BI Setup Guide in the Media LIbrary) you can get trendlines there. This BW integration also integrates back with SL Reporting.
    Some guidance for SL Reporting is probably given under https://service.sap.com/rkt-solman but I am not 100% sure.

  • How to find a specific word in sentence in each line?

    How to find a specific word in sentence in each line and output will show start from the beginning from specific word plus with small description from each sentence?
    For example: I need to find a "+Wednesday+" and "+Thursday+" word in each sentence by line by line from "myfile.txt".
    Go ballet class next Wednesday.
    On the Wednesday is going to swim class.
    We have a meeting on Thursday at Panda's.
    Then it will show the output:
    Wednesday : ballet class
    Wednesday : swim class
    Thursday: meeting at Panda's
    I am going to figure out in Java console to read from a file for specific word from each line and how to make it output in correct way. I know already to make input/file codes.

    I got it and understand much better. Thank you very much. There is a problem with it because I knew how to make
    a specific word in sentence but how I should make Output for specific word and some words from sentence.
    For example:
    Input:
    +"On Thursday go to ballet class"+
    +"Swim class on Friday one time a month at 2 p.m."+
    I used the codes for that:
    class FindSchedule{
         String firstline = "On Thursday go to ballet class ";
         String secondline = "Swim class on Friday one time a month ";
         FindSchedule(){
              System.out.println(firstline + findTheIndex("Thursday", firstline));
              System.out.println(secondline + findTheIndex("Friday", secondline));
         public int findTheIndex(String word, String sentence){
              int index;
              index = sentence.indexOf(word);
              return index;
         public static void main (String[] args){
              new FindSchedule();
    }The output will be:
    Thursday: ballet class
    Friday: 14:00 swim class one time a week
    Notice that time is changing in output complete different from input.
    I need to find out how to extract some words from each sentence for output. Do you know how to do it?

  • How can i print specific pages against searched word or name (in one print command) from 1000 pages

    how can i print specific pages against searched word or name (in one print command) from 1000 pages

    Thanks, Alex!
    ok, I try first approach in print4.vi, but Labview return an error (view jpg); if I cut From, To controls, the VI print all pages. The same things happen also if I trasform I32 in Variant.
    I don't try second approach, because at this time I have only one report
    I try also with VB macro: this is better (print3.vi) but.....if I use:
    Sub Print_Pages_From_To()
    ActiveDocument.ActiveWindow.PrintOut Range:=wdPrintFromTo, From:="2", To:="3"
    End Sub
    is ok; print the pages selected; if I use:
    Sub PrintPages()
    ActiveDocument.ActiveWindow.PrintOut  Pages:="2-3"  
    End Sub
    printer print all pages.
    what do you think?

  • HT2513 how do I share specific events on my calendar with others?

    How do I share specific events on my calendar with others?

    To share an entire calendar via mac and icloud you will either need a iCal server or to login with your icloud account with the computer you want the calendar on. I find the easiest way to share calendars is to sync your calendar with Google Calendar. Login to Google Calendar, under the "My Calendars" Tab on the left side, find the calendar you would like to share. Hover over it with the mouse and an upside down triangle will appear a little to the right of the calendar name. Click on the triangle and click share this calendar.

  • [solved] How to source a specific commit in a Git package?

    Hi there,
    I wonder whether it is possible to use a certain Git commit in the source array of a package.
    Example:
    freshplayerplugin-git
    For debugging purposes I would like to use the commit
    8ff0bd0282205802c482c7d47f216feb0d3394a9
    I tried the following in the source array and it successfully built the package:
    source=('git://github.com/i-rinat/freshplayerplugin.git#commit=8ff0bd0282205802c482c7d47f216feb0d3394a9')
    However, I have no idea how to detect whether it actually built from the specific commit or just skipped the #commit appending.
    Does anyone know how to source a specific commit?
    Thanks ahead!

    Correct syntax for Git repository as a source would be:
    source=('git+https://<repo-url>#[commit|tag|branch]=<ref>')
    To verify it's building correct tree, and moreover to keep sane when dealing with multiple trees I like following pkgver (check https://wiki.archlinux.org/index.php/VC … Guidelines):
    pkgver() {
    cd "$srcdir/<repo-name>"
    printf 'r%s.%s' "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
    producing something like:
    <package-name-git>-r4.34e558d-1-any.pkg.tar.xz
    Also just going to fetched Git tree and checking out what's there is an option (look for makepkg branch), for example:
    $ git show-ref
    34e558d2ef8b2cae212da3ab3f74513a99f9ee1b refs/heads/makepkg
    86350ab5a3a209de4339ef04d75d27c7bd399746 refs/heads/master
    86350ab5a3a209de4339ef04d75d27c7bd399746 refs/remotes/origin/HEAD

  • Hi, I don't know how to find a specific security patch to apply to my Oracle database version to fix a vulnerability

    Hi, I don't know how to find a specific security patch to apply to my Oracle database version 11.2.0.2.0 (on windows server 2003 32 bits) to fix the following vulnerability:
    Risk: High
    Application: oracle_tnslsnr
    Port: 1521
    Protocol: tcp
    Synopsis:
    It is possible to register with a remote Oracle TNS listener.
    Description:
    The remote Oracle TNS listener allows service registration from a remote host. An attacker can exploit this issue to divert data from a
    legitimate database server or client to an attacker-specified system.
    Successful exploits will allow the attacker to manipulate database instances, potentially facilitating man-in-the-middle, sessionhijacking,
    or denial of service attacks on a legitimate database server.
    Solution:
    Apply the work-around in Oracle's advisory.
    Thank you for your help
