  • Printer image correction

    - by Matthew Shinal
    Here is my problem: my printer and scanner (HP psc2410xi) prints darker than the photos taken and teh scanner has a background fuzz. I want to create and install files to have the printer lighten the photos it prints (yellow becomes dark yellow, etc) and delete the "fuzz" from the scanner image (you can see it on a blank scan and yes I did clean the scanner). I'm thinking there is a way to take a printed image, scan that in, and subtract the two images from each other to get the correction factor.

  • How to implement explosion in OpenGL with a particle effect?

    - by Chan
    I'm relatively new to OpenGL and I'm clueless how to implement explosion. So could anyone give me some ideas how to start? Suppose the explosion occurs at location $(x, y, z)$, then I'm thinking of randomly generate a collection of vectors with $(x, y, z)$ as origin, then draw some particle (glutSolidCube) which move along this vector for some period of time, says after 1000 updates, it disappear. Is this approach feasible? A minimal example would be greatly appreciated.

  • Need help drawings planets in Java.

    - by d33j
    I am looking for help/links/notes/agorithms/URLs/examples on drawing/rendering spheres in pure Java (so that I can hopefully, one day, generate/render planets with various surfaces & atmospheres) So for the moment, i'd be pretty happy to be able to start off with just drawing a wireframed sphere(s). ps: I don't want to use external libraries like Java3D, JOGL or aftermarket engines like JMonkeyEngine, Would rather keep it as straight Java.

  • A little on speaking and evaluations...

    - by AaronBertrand
    Buck Woody ( blog | twitter ) just published a great post on session evaluations , and a lot of his points hit home for me. The premise is that the evaluations are not really meant for the attendee or the event organizers, but so that the speaker can get better and make the next session better. In light of this, at least in my opinion, the existing evaluation forms (and the way attendees tend to fill them out) do not achieve this at all. It may be a little more work for events to generate a more...(read more)

  • How to use data mining principles in this project?

    - by Simon
    I'm getting a Data Mining class this semester and we are free for the final project. For a few months I'm working on procedural planets rendering (something like this http://www.youtube.com/watch?v=rL8zDgTlXso). Do you have any idea of which data mining principles I could use to keep working this project ? Maybe I could try to generate interesting terrains from a set of real maps ? Any publications on that subject ? Any other ideas ?

  • Intersection points of plane set forming convex hull

    - by Toji
    Mostly looking for a nudge in the right direction here. Given a set of planes (defined as a normal and distance from origin) that form a convex hull, I would like to find the intersection points that form the corners of that hull. More directly, I'm looking for a way to generate a point cloud appropriate to provide to Bullet. Bonus points if someone knows of a way I could give bullet the plane list directly, since I somewhat suspect that's what it's building on the backend anyway.

  • 'dd' access to a drive

    - by John
    I've been working with making custom bootloader and kernel code (not necessarily Linux kernel). I'm putting the images on USB, and was using dd to place them on the sector they needed to be on, and I'm getting tired of burning the image to /dev/sda instead of /dev/sdb (effectively destroying my hard drive). So I was wondering if I could somehow give user access to the 'dd' command, but only to the /dev/sdb drive, so that if I accidentally type /dev/sda it won't let me, because I wouldn't have run the command as sudo or root.

  • SQLSaturday #162 : Cambridge, England

    - by AaronBertrand
    Yesterday I presented at SQL Saturday #162 . My slide deck and samples are here: Slide Deck & Samples: Bertrand - T-SQL Bad Habits & Best Practices I also wanted to answer a question from an audience member after the session about how to generate YYYYMMDD strings to represent yesterday's date in order to append to a backup file name. In this case because we're probably not worried about performance (you're performing this calculation once), we can just use string conversion (see this blog...(read more)

  • Can I use Ubuntu to write a Windows 7 ISO to USB in Ubuntu?

    - by Salim Fadhley
    I need to create a Windows installation USB drive from an ISO file. I used unetbootin which seems to be the only tool that can write non-linux images. The USB disk boots (sort-of), but it gets stuck at the very first stage. A UNetbootin spash screen that keeps counting-down from ten to 0, and then restarts. The screen looks like this: Is there a way to make Windows boot from a USB image created on Linux?

  • What alternatives to Animated GIFs are natively supported on all popular modern browsers on tablets, etc. without pluggins?

    - by Clay Nichols
    I was looking for an alternative animated images to Animated GIFS. But per CanIUseit support for APNGs seems to being phased out. And MNG support isn't even listed there and pages about it don't even mention Chrome (suggesting those pages are very very old) Clarification: This is for a web app, so it'll need to support: - Safari on iPad (so can't depend on extensions) - Chrome on Windows and Mac - Safari 6.0+ on Mac - Chrome on Android

  • Nautilus Image Converter: strip EXIF metadata

    - by plua
    I just found out that images can have more than 20KB of EXIF data. Not really an issue with 2MB files, but if you have small thumbnails this really adds up. I use mogrify often to resize, and I can use mogrify -strip to remove the EXIF data. However, if I use Nautilus Image Converter there is no way to strip this data. Is there something in the configuration I can set so it always automatically adds the -strip flag to the command?

  • invalid / unauth Product Key (10 replies)

  • JGridView (Part 2)

    - by Geertjan
    The second sample in the JGrid download is a picture viewer that needs to be seen to be believed. Here it is, integrated into a NetBeans Platform application (click to enlarge it): When you mouse over the images, they change, showing several different images instantaneously. Here's the explorer view above, mainly making use of code from the sample: public class JGridView extends JScrollPane { @Override public void addNotify() { super.addNotify(); final ExplorerManager em = ExplorerManager.find(this); if (em != null) { final JGrid grid = new JGrid(); Node root = em.getRootContext(); final Node[] nodes = root.getChildren().getNodes(); final PicViewerObject[] pics = new PicViewerObject[nodes.length]; for (int i = 0; i < nodes.length; i++) { Node node = nodes[i]; pics[i] = node.getLookup().lookup(PicViewerObject.class); } grid.getCellRendererManager().setDefaultRenderer(new PicViewerRenderer()); grid.setModel(new DefaultListModel() { @Override public int getSize() { return pics.length; } @Override public Object getElementAt(int i) { return pics[i]; } }); grid.setFixedCellDimension(160); grid.addMouseMotionListener(new MouseAdapter() { int lastIndex = -1; @Override public void mouseMoved(MouseEvent e) { if (lastIndex >= 0) { Object o = grid.getModel().getElementAt(lastIndex); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(lastIndex); if (r != null && !r.contains(e.getPoint())) { ((PicViewerObject) o).setMarker(false); grid.repaint(r); } } } int index = grid.getCellAt(e.getPoint()); if (index >= 0) { Object o = grid.getModel().getElementAt(index); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(index); if (r != null) { ((PicViewerObject) o).setFraction(((float) e.getPoint().x - (float) r.x) / (float) r.width); ((PicViewerObject) o).setMarker(true); lastIndex = index; grid.repaint(r); } } } } }); grid.getSelectionModel().addListSelectionListener(new ListSelectionListener() { @Override public void valueChanged(ListSelectionEvent e) { //Somehow compare the selected item //with the list of books and find a matching book: int selectedIndex = grid.getSelectedIndex(); for (int i = 0; i < nodes.length; i++) { int picId = pics[i].getId(); if (selectedIndex == picId) { try { em.setSelectedNodes(new Node[]{nodes[i]}); } catch (PropertyVetoException ex) { Exceptions.printStackTrace(ex); } } } } }); setViewportView(grid); } } } The next step is to create a generic JGridView that will handle any kind of object automatically.
