  • Flickering Image in Java?

    - by Noah Cagle
    OK so I am coding a game right now to prepair for Ludum Dare SharkJam, and I am using a new method for programming, because the last method I had crashes my PC, so this one should work. Well it does work and all, better too, but the images that I put in it flicker. Here is the whole main class (where the images are drawn) package me.NoahCagle.watermaze; import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferedImage; import javax.swing.JFrame; import me.NoahCagle.watermaze.entity.EntityShark; import me.NoahCagle.watermaze.entity.Player; import me.NoahCagle.watermaze.input.Keys; import me.NoahCagle.watermaze.map.Map; public class Game extends JFrame { private static final long serialVersionUID = 1L; Map map = new Map(0, 0); Player player = new Player(50, 30); static EntityShark shark = new EntityShark(400, 400); public Image dbImage; public Game() { setSize(800, 600); setDefaultCloseOperation(EXIT_ON_CLOSE); setLocationRelativeTo(null); setVisible(true); setTitle("Water Maze"); setResizable(false); setBackground(Color.blue); addKeyListener(new Keys()); } public static void main(String[] args) { new Game(); Thread s = new Thread(shark); s.start(); } public void paint(Graphics g) { dbImage = new BufferedImage(getWidth(), getHeight(), BufferedImage.TYPE_INT_RGB); g.drawImage(dbImage, map.x, map.y, null); g.drawImage(player.player, player.x, player.y, this); g.drawImage(shark.shark, shark.x, shark.y, this); repaint(); } } What this code does for me is makes the Images work correctly, just flickering, alot. Can anyone help me with my issue? EDIT: I think it has something to do with where I call the repaint method in the paint method, so look there.

  • Jetty: Mount to a directory on a different host

    - by jettyQuestion
    I'm looking to map to a directory on a different host using Jetty/Maven when working locally. I've found you can do this w/ Apache using mod_jk (JkMount/JkUnMount), but haven't figured it how to do the same on jetty. On our dev/q/live servers, we have Apache in front of JBoss and use mod_jk to do this. Locally, we're using jetty To give you an idea of what I'm talking about, this is how you would configure Apache to accomplish this: in httpd.conf: JkMount /images/* host2 JkMount /* host2 JkUnMount /images/* host1 workers.properties: worker.list=host2,host1 worker.host2.host=host-2.theDomain.com worker.host2.port=46654 worker.host1.host=host-1.theDomain.com worker.host1.port=46655 Is there a way to configure Jetty to do the same thing? Btw, locally, I'm using the Maven plugin for Eclipse if that makes a difference. thanks!

  • jQuery/CSS related problem

    - by MrAwesome
    Hi I am new to jQuery, and this is the page I'm currently developing. http://90.230.237.71/gandhi.html (Hope that works now :P) When I hit "Show/hide gallery" all the images are first opened vertically, and later they are corrected to their horizontal placement, that's the problem. They should be horizontal right away! I don't know if this is due to jQuerys slideDown or entirely CSS-related, but the code is all there for you. Initally, the images are set to display: none, perhaps they then are invisibly stored vertically. Then slideDown is performed and last, the CSS-attributes are changed to "display: inline". Perhaps I need to change execution order of slideDown and setting the CSS-attributes... but how? I NEED HELP... for many reasons, but I only want you to help me with this one ;) And also, please actually look at the code before making any assumptions. It's all there in the code.

  • iPhone - Adding new sections and rows into UITableView

    - by Dev
    I have a UITableView to display a list of data. The list will contain images, so I am loading images with lazy loading. Now I don't want to load the whole list at a time. The loading should be like, first it should load some 10 records and when we scrolling down to the tableview, it should automatically load next 10 records as on. For this I need to add rows when I am scrolling to bottom. The tableview may contain different sections. So how can I add new rows and new sections at the end of the tableview while scrolling down?

  • How to display Youtube videos in a jQuery lightbox (Wordpress)?

    - by janoChen
    I tried lightbox-plus, fancybox, etc... But I couldn't figure how to do it. Those videos are images posts with a link containing a Youtube video: <p><a href="http://www.youtube.com/watch?v=zUN826BdvV4"> <img class="alignnone size-thumbnail wp-image-40" title="Screenshot" src="http://localhost/custom-post-type/ wp-content/uploads/2011/01/Screenshot2-150x150.png" alt="" width="150" height="150" /></a></p> Fancybox for Wordpress, for example, let me add a lightbox to images, but if the image links to a Youtube video it doesn't work. Any suggestions?

  • Efficient method of finding database rows that have *one or more* qualities from a list of seven qualities

    - by hithere
    Hello! For this question, I'm looking to see if anyone has a better idea of how to implement what I'm currently planning on implementing (below): I'm keeping track of a set of images, using a database. Each image is represented by one row. I want to be able to search for images, using a number of different search parameters. One of these parameters involves a search-by-color option. (The rest of the search stuff is currently working fine.) Images in this database can contain up to seven colors: -Red -Orange -Yellow -Green -Blue -Indigo -Violet Here are some example user queries: "I want an image that contains red." "I want an image that contains red and blue." "I want an image that contains yellow and violet." "I want an image that contains red, orange, yellow, green, blue, indigo and violet." And so on. Users make this selection through the use of checkboxes in an html form. They can check zero checkboxes, all seven, and anything in between. I'm curious to hear what people think would be the most efficient way to perform this database search. I have two possible options right now, but I feel like there must be something better that I'm not thinking of. (Option 1) -For each row, simply have seven additional fields in the database, one for each color. Each field holds a 1 or 0 (true/false) value, and I SELECT based on whatever the user has checked off. (I didn't like this solution so much, because it seemed kind of wasteful to add seven additional fields...especially since most pictures in this table will only have 3-4 colors max, though some could have up to 7. So that means I'm storing a lot of zeros.) Also, if I added more searchable colors later on (which I don't think I will, but it's always possible), I'd have to add more fields. (Option 2) -For each image row, I could have a "colors" text field that stores space-separated color names (or numbers for the sake of compactness). Then I could do a fulltext match against search through the fields, selecting rows that contain "red yellow green" (or "1 3 4"). But I kind of didn't want to do fulltext searching because I already allow a keyword search, and I didn't really want to do two fulltext searches per image search. Plus, if the database gets big, fulltext stuff might slow down. Any better options that I didn't think of? Thanks! Side Note: I'm using PHP to work with a MySQL database.

  • Hibernate won't autogenerate sequence table

    - by Jason
    I'm trying to use a sequence table to generate keys for my entities. I notice that if I just use the @GeneratedValue(strategy=GenerationType.TABLE) with no explicit generator, Hibernate will automatically create the hibernate_sequences table in my DB if it doesn't exist. This is great. However, I wanted to make some changes to the sequence table, so I created a @TableGenerator like the following: @GeneratedValue(strategy=GenerationType.TABLE, generator="vdat_seq") @TableGenerator(name="vdat_seq", table="VDAT_SEQ", pkColumnName="seq_name", valueColumnName="seq_next_val", allocationSize=1) This works fine if I manually create the VDAT_SEQ table in my schema; Hibernate won't auto-create it anymore. This causes an issue in my unit tests, since I'd rather not have to manually create a table and maintain it on our testing DB. Is there a configuration variable or some other way to get Hibernate to generate the sequence table?

  • Syntax problem when checking for a file

    - by Luke
    This piece of code has previously worked but I have C&P it to a new place and for some reason, it now won't work! <? $user_image = '/images/users/' . $_SESSION['id'] . 'a.jpg'; if (file_exists(realpath(dirname(__FILE__) . $user_image))) { echo '<img src="'.$user_image.'" alt="" />'; } else { echo '<img src="/images/users/small.jpg" alt="" />'; } ?> As you can see, I am checking for a file, if exists, showing it, if not, showing a placeholder. The $_SESSION['id'] variable does exist and is being used elsewhere within the script. Any ideas what the problem is? Thanks

  • How to move many files in multiple different directories (on Linux)

    - by user1335982
    My problem is that I have too many files in single directory. I cannot "ls" the directory, cos is too large. I need to move all files in better directory structure. I'm using the last 3 digits from ID as folders in reverse way. For example ID 2018972 will gotta go in /2/7/9/img_2018972.jpg. I've created the directories, but now I need help with bash script. I know the IDs, there are in range 1,300,000 - 2,000,000. But I can't handle regular expressions. I wan't to move all files like this: /images/folder/img_2018972.jpg -> /images/2/7/9/img_2018972.jpg I will appreciate any help on this subject. Thanks!

  • Render Silverlight Animation to video file

    - by VOliveira
    Hi guys I need to be able to render a silverlight storyboard animation to video. The animated content itself could be simple UIElements, Images or even two or more videos playing at the same time. Several ideas came to mind like RenderTargetBitmap on a single frame basis, but: 1) I've never tested this against video embedded content 2) Don't know how to actually compose the video from the generated images. Expression Encoder was also on my mind, but I don't know if it's possible to integrate it in a Silverlight/XBAP app to fulfill what's expected from it. What's your opinion on this?

  • HTML5 - Creating a canvas on top of an SVG(or other image)

    - by cawd
    The reason for asking this question is because I want to be able to draw an arrow between two svg images. I want to use canvas to create the arrows, so firstly I generate the svgs then place a canvas on top of them to be able to draw the arrows. I've tried using style=... but haven't had any luck as everytime I add the canvas element it just pushes my svg images to another pl If there's no easy way to do this I'll just create arrows using SVG, I figured it would be more efficient to use canvas if I had to do lots of arrows in a short amount of time.

  • What's some simple F# code that generates the .tail IL instruction?

    - by kld2010
    I'd like to see the .tail IL instruction, but the simple recursive functions using tail calls that I've been writing are apparently optimized into loops. I'm actually guessing on this, as I'm not entirely sure what a loop looks like in Reflector. I definitely don't see any .tail opcodes though. I have "Generate tail calls" checked in my project's properties. I've also tried both Debug and Release builds in Reflector. The code I used is from Programming F# by Chris Smith, page 190: let factorial x = // Keep track of both x and an accumulator value (acc) let rec tailRecursiveFactorial x acc = if x <= 1 then acc else tailRecursiveFactorial (x - 1) (acc * x) tailRecursiveFactorial x 1 Can anyone suggest some simple F# code which will indeed generate .tail?

  • Check directory exists and if it doesnt choose an image

    - by Andy
    I have this code so far which perfectly but relies on there being a directory in place: $path = '/home/sites/therealbeercompany.co.uk/public_html/public/themes/trbc/images/backgrounds/'.$this->slug; $bgimagearray = array(); $iterator = new DirectoryIterator($path); foreach ($iterator as $fileinfo) { if ($fileinfo->isFile() && !preg_match('\.jpg$/', $fileinfo->getFilename())) { $bgimagearray[] = "'" . $fileinfo->getFilename() . "'"; } } I need to work in a bit at the top so that if the directory doesnt exist it defaults to the images sat in the root of the background directory... Any help would be appreciated.

  • Design cache mechanism

    - by Delashmate
    Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

  • How to encode(represent) an ornament?

    - by Daniyar
    I would like to find a numeric representation of kazakh national ornaments for generating new ones. The ornaments essentially consist of combinations of relatively basic ornaments. Usually the ornaments are symmetrical. Here are few examples of basic elements: (The images are a bit distorted) And this is an example of a more complex ornament: How could I encode an ornament's representation in as few numbers as possible? So that I could write a program that would generate an ornament, given some sequence of numbers Any ideas are appreciated. As I write this, I have thought that generating images of snowlfakes may be somewhat relevant, although it's possibly just a fractal.

  • Randomly choose value between 1 and 10 with equal number of instances

    - by user1723765
    I would like to generate 2000 random numbers between 1 and 10 such that for each random number I have the same number of instances. In this case 200 for each number. What should be random is the order in which it is generated. I have the following problem: I have an array with 2000 entries but not each with unique values, for example it starts like this: 11112233333333344445667777777777 and consists of 2000 entries. I would like to generate random numbers and assign each UNIQUE value a separate random number but have an entry for each value So my intended result would look like this: original array: 11112233333333344445667777777777 random numbers: 33334466666666699991778888888888
