  • xubuntu 12.04 can't change desktop background/wallpaper permanently

    - by Frank
    If I change the desktop background (wallpaper) via right-click on desktop = desktop settings = single image, and select another background image from the list, or add a photo of my own (via the "+" symbol), I can actually change the background image, but after logging out or restarting, the wallpaper is always reset to the original xubuntu 12.04 background. So, basically, I can't find a way to permanently change the desktop background. Any ideas?

  • How to make my simple round sprite look right in XNA

    - by Joshua Perina
    Ok, I'm very new to graphics programming (but not new to coding). I'm trying to load a simple image in XNA which I can do fine. It is a simple round circle which I made in photoshop. The problem is the edges show up rough when I draw it on the screen even with the exact size. The anti-aliasing is missing. I'm sure I'm missing something very simple: GraphicsDevice.Clear(Color.Black); // TODO: Add your drawing code here spriteBatch.Begin(); spriteBatch.Draw(circle, new Rectangle(10, 10, 10, 10), Color.White); spriteBatch.End(); Couldn't post picture because I'm a first time poster. But my smooth png circle has rough edges. So I found that if I added: spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.NonPremultiplied); I can get a smooth image when the image is the same size as the original png. But if I want to scale that image up or down then the rough edges return. How do I get XNA to smoothly resize my simple round image to a smaller size without getting the rough edges?

  • Can WebGL be used to create a tile-based multi-layer scrolling platform game?

    - by Nicholas Hill
    I've found WebGL (based on OpenGL) to be a fiendish and unforgiving framework for those learning to write HTML5-based games. Despite the presence of many examples on how to get started, I'm really struggling to understand how I could simply load a bunch of images and render them to a canvas quickly using WebGL. My specific scenario involves trying to render a map using a bespoke but simple multi-layered tile engine, where each value in a three dimensional array points to the image to use for that location in the rendered image. Think "Sonic the Hedgehog" via tilesets, tiles, maps, layers, sprites etc. Can anyone enlighten me: 1) How can I load an image that I can use as a texture in WebGL? 2) How can I dynamically select an image at run time and draw it at any co-ordinate, that I also select at run time?

  • How to change my website's appearance in a Facebook wall post?

    - by Lode
    When posting a website link in a Facebook wall post, Facebook fetches some content (title, text and image) from the website to show it to readers. Is there a way I can adjust / propose which content is used / preferred by Facebook? I found someone saying to use <meta property="og:image" content="image.jpg">, but this doesn't seem to have any effect. But maybe Facebook caches these results for a while?

  • Grub not showing installed kernels

    - by Markus
    Although I have several kernel versions in /boot and having them in my grub.cfg, they are not displayed in the grub boot menu. Running update-grub seems to work, as it puts the kernels in the grub.cfg in /boot/grub.

  • TGA loader: reverse height

    - by aVoX
    I wrote a TGA image loader in Java which is working perfectly for files created with GIMP as long as they are saved with the option "origin" set to "Top Left" (Note: Actually TGA files are meant to be stored upside down - "Bottom Left" in GIMP). My problem is that I want my image loader to be capable of reading all different kinds of TGAs, so my question is, how do I flip the image upside down? Note that I store all image data inside a one-dimensional byte array, because OpenGL (glTexImage2D to be specific) requires it that way. Thanks in advance.

  • Difficulties with rotation of a sprite

    - by Andy
    I want to program a dolphin that jumps and rotates like a real dolphin. Jumping is not the problem, but I don't know how to make the rotation. My dolphin always rests in the same angle while it jumps. But I want that it changes the rotation during the jump, like a real dolphin does. How can I improve the rotation? public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D image, water; float Gravity = 5.0F; float Acceleration = 20.0F; Vector2 Position = new Vector2(1200,720); Vector2 Velocity; float rotation = 0; SpriteEffects flip; Vector2 Speed = new Vector2(0, 0); public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; graphics.PreferredBackBufferWidth = 1280; graphics.PreferredBackBufferHeight = 720; } protected override void Initialize() { base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); image = Content.Load<Texture2D>("cartoondolphin"); water = Content.Load<Texture2D>("background"); flip = SpriteEffects.None; } protected override void Update(GameTime gameTime) { float VelocityX = 0f; float VelocityY = 0f; float time = (float)gameTime.ElapsedGameTime.TotalSeconds; KeyboardState kbState = Keyboard.GetState(); if(kbState.IsKeyDown(Keys.Left)) { rotation = 0; flip = SpriteEffects.None; VelocityX += -5f; } if(kbState.IsKeyDown(Keys.Right)) { rotation = 0; flip = SpriteEffects.FlipHorizontally; VelocityX += 5f; } // jump if the dolphin is under water if(Position.Y >= 670) { if (kbState.IsKeyDown(Keys.A)) { if (flip == SpriteEffects.None) { rotation = 45; VelocityY += 40f; } else { rotation = -45; VelocityY += 40f; } } } else { VelocityY += -10f; } float deltaY = 0; float deltaX = 0; deltaY = Gravity * (float)gameTime.ElapsedGameTime.TotalSeconds; deltaX += VelocityX * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; deltaY += -VelocityY * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; Speed = new Vector2(Speed.X + deltaX, Speed.Y + deltaY); Position += Speed * (float)gameTime.ElapsedGameTime.TotalSeconds; Velocity.X = 0; if (Position.Y + image.Height/2 > graphics.PreferredBackBufferHeight) Position.Y = graphics.PreferredBackBufferHeight - image.Height/2; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(water, new Rectangle(0, graphics.PreferredBackBufferHeight -100, graphics.PreferredBackBufferWidth, 100), Color.White); spriteBatch.Draw(image, Position, null, Color.White, MathHelper.ToRadians(rotation), new Vector2(image.Width / 2, image.Height / 2), 1, flip, 1); spriteBatch.End(); base.Draw(gameTime); } }

  • Preview.app only auto-refreshes if you alt-tab to it.

    - by dreeves
    I'm working on a program that generates an image. I can keep the image open in Preview and when the image changes, Preview refreshes it, but only when I alt-tab (sorry, command-tab) to it. I'd like to keep the image in view and have it auto-refresh without touching it. Is that possible? (One ridiculous way I've found to do this is with a script that converts the image to a PDF file which I can keep open in Skim.app (a PDF reader) which has that ability.)

  • What is the recommended MongoDB schema for this quiz-engine scenario?

    - by hughesdan
    I'm working on a quiz engine for learning a foreign language. The engine shows users four images simultaneously and then plays an audio file. The user has to match the audio to the correct image. Below is my MongoDB document structure. Each document consists of an image file reference and an array of references to audio files that match that image. To generate a quiz instance I select four documents at random, show the images and then play one audio file from the four documents at random. The next step in my application development is to decide on the best document schema for storing user guesses. There are several requirements to consider: I need to be able to report statistics at a user level. For example, total correct answers, total guesses, mean accuracy, etc) I need to be able to query images based on the user's learning progress. For example, select 4 documents where guess count is 10 and accuracy is <=0.50. The schema needs to be optimized for fast quiz generation. The schema must not cause future scaling issues vis a vis document size. Assume 1mm users who make an average of 1000 guesses. Given all of this as background information, what would be the recommended schema? For example, would you store each guess in the Image document or perhaps in a User document (not shown) or a new document collection created for logging guesses? Would you recommend logging the raw guess data or would you pre-compute statistics by incrementing counters within the relevant document? Schema for Image Collection: _id "505bcc7a45c978be24000005" date 2012-09-21 02:10:02 UTC imageFileName "BD3E134A-C7B3-4405-9004-ED573DF477FE-29879-0000395CF1091601" random 0.26997075392864645 user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioFiles [ 0 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "English" date 2012-09-22 01:15:04 UTC } 1 { audioFileName "C3669719-9F0A-4EB5-A791-2C00486665ED-30305-000039A3FDA7DCD2" user "2A8761E4-C13A-470E-A759-91432D61B6AF-25982-0000352D853511AF" audioLanguage "Spanish" date 2012-09-22 01:17:04 UTC } ]

  • All images are gone after open a doc file created by libreoffice writer

    - by user71465
    I got a paper template in .doc format from a conference site. Now when i work on it with libreoffice and insert image to it and insert caption for the image, after closing the file and opening it again, all images are gone. I saw that when the image Anchor is set "to frame" the image will be gone but when it is set to e.g. "to paragraph" it will maintain but it's alignment will be corrupted. Also, i need the Anchor to be set to "Frame". What can I do? I searched the net but i didn't find a good answer.

  • Best Practice Method for Including Images in a DataGrid using MVVM

    - by Killercam
    All, I have a WPF DataGrid. This DataGrid shows files ready for compilation and should also show the progress of my compiler as it compiles the files. The format of the DataGrid is Image|File Path|State -----|---------|----- * |C:\AA\BB |Compiled & |F:PP\QQ |Failed > |G:HH\LL |Processing .... The problem is the image column (the *, &, and are for representation only). I have a ResourceDictionary that contains hundreds of vector images as Canvas objects: <ResourceDictionary xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Canvas x:Key="appbar_acorn" Width="48" Height="48" Clip="F1 M 0,0L 48,0L 48,48L 0,48L 0,0"> <Path Width="22.3248" Height="25.8518" Canvas.Left="13.6757" Canvas.Top="11.4012" Stretch="Fill" Fill="{DynamicResource BlackBrush}" Data="F1 M 16.6309,18.6563C 17.1309,8.15625 29.8809,14.1563 29.8809,14.1563C 30.8809,11.1563 34.1308,11.4063 34.1308,11.4063C 33.5,12 34.6309,13.1563 34.6309,13.1563C 32.1309,13.1562 31.1309,14.9062 31.1309,14.9062C 41.1309,23.9062 32.6309,27.9063 32.6309,27.9062C 24.6309,24.9063 21.1309,22.1562 16.6309,18.6563 Z M 16.6309,19.9063C 21.6309,24.1563 25.1309,26.1562 31.6309,28.6562C 31.6309,28.6562 26.3809,39.1562 18.3809,36.1563C 18.3809,36.1563 18,38 16.3809,36.9063C 15,36 16.3809,34.9063 16.3809,34.9063C 16.3809,34.9063 10.1309,30.9062 16.6309,19.9063 Z "/> </Canvas> </ResourceDictionary> Now, I want to be able to include these in my image column and change them at run-time. I was going to attempt to do this by setting up a property in my View Model that was of type Image and binding this to my View via: <DataGrid.Columns> <DataGridTemplateColumn Header="" Width="SizeToCells" IsReadOnly="True"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <Image Source="{Binding Canvas}"/> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> </DataGrid.Columns> Where in the View Model I have the appropriate property. Now, I was told this is not 'pure' MVVM. I don't fully accept this, but I want to know if there is a better way of doing this. Say, binding to an enum and using a converter to get the image? Any advice would be appreciated.

  • Upgrading to 9.2 - Info You Can Use (part 2 - Get Hands On Experience)

    - by John Webb
    Our guest blogger, Rebekah Jackson, continues with a series of helpful hints on planning your upgrade to PeopleSoft 9.2. Get Hands-On Experience With a an Easy to Install Demo Image Once you have identified the features you believe can add value (see part 1 of this series here), we recommend that you use our Demo Images to quickly create a PeopleSoft environment where you can try out the new features. The Demo Images are virtual machines that run in VirtualBox.   They contain a fully functioning PeopleSoft environment, including the database, PeopleTools, and the application.  These images can be loaded onto nearly any sized machine that meets the specs outlined in the documentation, including a powerful desktop machine.     The image allows you to very quickly deploy a fully functioning PeopleSoft instance that you can use to explore new features and functions or run a conference room pilot. To take advantage these Demo Images: Go to the Demo Images Home Page (Doc id 1552548.1) on My Oracle Support. Use the " Demo Image Quick Start Guide" and additional documentation links on that page to download and install your desired Demo Image. New Demo Images are posted for each product area approximately every 10 weeks, available shortly after the corresponding patching image. When installed, use the Demo Image to explore the desired features and capabilities. Important Notes: - It is not required to use the Demo Images to evaluate features and functions – any 9.2 instance will support this. We recommend use of the Demo Images because the setup and configuration is dramatically faster than doing a traditional PeopleSoft install. - For those looking to explore new features and capabilities on PeopleSoft 9.1 releases, we have provided virtual machine images using the Oracle Virtual Machine technology. Details and links are available in Oracle’s PeopleSoft Virtualization Products page (Doc id 1538142.1). /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif"; mso-bidi-font-family:"Times New Roman";}

  • Z-index preventing on hover attribute on another element [migrated]

    - by user18294
    I have two different elements (div class="") within a larger container. Let's call them div class="overlay_container" and div class="title." The div class="overlay_container" has a subclass, .image, which creates an overlay over the entire larger container on hover. The div class="title" has a z-index of 10,000 and lies over .image and therefore over the overlay. Unfortunately, when you hover over "title," the subclass overlay image underneath disappears. I know the problem is obviously that the "title" div is right over the other divs and therefore the on hover will disappear due to the z-index. But how do I fix this? How do I make it so that when you hover over the "title," the .image overlay still appears? If your answer involves jQuery, could you please tell me where to put the script (before the /head tag)? Thanks!

  • Android Bitmap: Collision Detecting

    - by Aekasitt Guruvanich
    I am writing an Android game right now and I would need some help in the collision of the Pawns on screen. I figured I could run a for loop on the Player class with all Pawn objects on the screen checking whether or not Width*Height intersects with each other, but is there a more efficient way to do this? And if you do it this way, many of the transparent pixel inside the rectangular area will also be considered as collision as well. Is there a way to check for collision between Bitmap on a Canvas that disregard transparent pixels? The class for player is below and the Pawn class uses the same method of display. Class Player { private Resources res; // Used for referencing Bitmap from predefined location private Bounds bounds; // Class that holds the boundary of the screen private Bitmap image; private float x, y; private Matrix position; private int width, height; private float velocity_x, velocity_y; public Player (Resources resources, Bounds boundary) { res = resources; bounds = boundary; image = BitmapFactory.decodeResource(res, R.drawable.player); width = image.getWidth(); height = image.getHeight(); position = new Matrix(); x = bounds.xMax / 2; // Initially puts the Player in the middle of screen y = bounds.yMax / 2; position.preTranslate(x,y); } public void draw(Canvas canvas) { canvas.drawBitmap(image, position, null); } }
