  • convert image to spritesheet of tiles for isometric map?

    - by Paul
    is there a way to convert an isometric image (like the first image) to a spritesheet (like the second image), in order to place each image on the isometric map with the code? The map looks like the first image, but some buildings are bigger than just one tile, so I need several squares (let's say the first image is a building, made of multiple tiles with different colors), and each square is placed with an offset of 64x32. The building is created in Blender and I save the image with the isometric perspective. But I have to split each square from this image in order to have the spritesheet, maybe there is smarter way, or a java software that would make the conversion for me?

  • Why does linux-image-virtual depend on a generic kernel now?

    - by ændrük
    The linux-image-virtual metapackage has historically provided a kernel that is specifically designed for use in virtual machines: Ubuntu 8.04: linux-image-2.6.24-32-virtual Ubuntu 10.04: linux-image-2.6.32-44-virtual Ubuntu 11.10: linux-image-3.0.0-26-virtual Ubuntu 12.04: linux-image-3.2.0-32-virtual Apparently, this has now changed: Ubuntu 12.10: linux-image-3.5.0-17-generic What's the explanation? Is this still the correct kernel to use in a virtual machine?

  • How to detect a touch on transparent area of an image in a (libgdx) stage?

    - by Usman
    Can some one please help to detect a touch on an image which I am using as an actor in a stage. The image is actually a long diagnol brush which has plenty of transparent area. The problem is when I touche the transparent area of the brush image it is also triggering the clicklistener of the image. I need the click listener should only be called when the finger actually touched the visible image not the area which is empty. I am using libgdx-0.9.4 libraries. Here is my simple piece of code. import com.badlogic.gdx.scenes.scene2d.ui.Image; import com.badlogic.gdx.scenes.scene2d.ui.ClickListener; Image brushImg = new Image(ImageCache.getTexture("brush")); brushImg.width = mStage.width()*0.75f; brushImg.height = mStage.height()*0.75f; brushImg.setClickListener(new ClickListener() { @Override public void click(Actor actor, float x, float y) { SoundFactory.play("brush"); }

  • Linking with an image: Background vs <img>

    - by FreshCode
    What is considered best practice (semantically) when using text with an image to link to an internal page or category? Option 1 <nav> <a href="/kittens"> <img src="kittens.png" /> <span>Kittens</span> </a> <a href="/puppies"> <img src="puppies.png" /> <span>Puppies</span> </a> </nav> Option 2 <nav> <a href="/kittens" class="kittens">Kittens</a> <a href="/puppies" class="puppies"><span>Puppies</a> </nav> where the CSS is defined: a.kittens { background-image:url("kittens.png"); width:40px; height:60px; } a.puppies { background-image:url("puppies.png"); width:40px; height:60px; } Should I use a styled background for the link, or an <img> inside the anchor element?

  • Create a system image in Windows 8

    - by Greg Low
    One of the things that I've just come to accept is that the designers of Windows 8 and I think very differently.It'll take a long time to convince me that shutting down the computer is a "setting". Even after using Windows 8 for quite a while now, I still find that I struggle nearly every day, just trying to do things that I previously knew how to do. That's just not a good thing.Today I decided to create a system image as I hadn't made one lately. I started in Control Panel looking for Backup options. That yielded nothing except programs that wanted to "Save backup copies of my files with file history". I thought "oh well, let's just try the new search options". I hit the Windows key and typed "Backup". No, nothing came up there either.I searched again all over the Control Panel options to no avail.So it was time to hit Google again. Once again, clearly lots of people used to know how to do this and have been trying to work out where this option went.The first trick is that there are a bunch of Control Panel options that don't appear in the Control Panel. In the address bar at the top, if you click on Control Panel, you'll find there is an option that says "All Control Panel Options". That is curious given that's where I thought I was when I opened Control Panel. No hint is given on that screen that there are a bunch of hidden options. None the less, I then checked out "all" the options.The option that you need to create a system image in Windows 8 turns out to be the "Windows 7 File Recovery" option that appears in this extended list. Why does it say "Windows 7" when it's for "Windows 8" as well and I'm running "Windows 8"? Why do I have to choose an option that says "File Recovery" to create a system image backup?<sigh>But at least I've recorded it here for the next time I forget where to find it.

  • Scale an image with unscalable parts

    - by Uko
    Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

    - by Madan Mohan
    Hi Guys, I am getting the data form Parser, In that I am getting a set of urls. Using these urls can I make image url by appending any data values getting from the parser. http://musicbrainz.org/ws/1/artist/f27ec8db-af05-4f36-916e-3d57f91ecf5e?type=xml&inc=url-rels+artist-rels using these url i get data and set of urls.They are not providing image url or thumbnail. So, Is it possible to get or form an image url from parser (http://musicbrainz.org/ws/1/artist/f27ec8db-af05-4f36-916e-3d57f91ecf5e?type=xml&inc=url-rels+artist-rels) and display in the web view. Please help me from this problem. Thank You, Madan Mohan.

  • Getting a JPEG image from a hex string in XML.

    - by Jesse Knott
    Well here goes, I am trying to collect a picture that is encoded as a hex string in an xml file. I have been looking all over for the answer to this and have not been able to find it any where. Here is what I have now. byte[] bytes = Convert.FromBase64String(FilterResults("PHOTOGRAPH")); MemoryStream mem = new MemoryStream(bytes); Image bmp2 = Image.FromStream(mem); return bmp2; The FilterResults function just returns the string from the XML. I am able to get the string of characters and convert it into a byte[] but as soon as I execute the Image.FromStream(mem) I get an "Parameter Incorrect" error. Any ideas?

  • Why can't I set the Image Source in WPF app?

    - by elmonty
    I'm just learning WPF. I'm using VS 2008. I've added an Image control to my XAML, and I added a GIF file to the project. If I use the XAML Designer's property panel to set the image's Source property, the drop-down list for the Source property contains the following: C:\Sample Project;component/pinHorizontal.gif There are several problems with this: My project, named "Sample Project," is not in the root of my drive. Why is ";component" in there? If I select this value as given, I get the error "Property value is not valid" (yeah, no kidding). If I go into the XAML source and set the Source property manually, like so: The XAML Designer gives me this error: "The file pinHorizontal.gif is not part of the project or its 'Build Action' property is not set to 'Resource'." Why is this task so difficult? How do I assign an image source?

  • Java Swing: how to add an image to a JPanel ?

    - by Leonel
    I have a JPanel to which I'd like to add JPEG and PNG images that I generate on the fly. All the examples I've seen so far in the Swing Tutorials, specially in the Swing examples use ImageIcons. I'm generating these images as byte arrays, and they are usually larger than the common icon they use in the examples, at 640x480. Is there any (performance or other) problem in using the ImageIcon class to display an image that size in a JPanel ? What's the usual way of doing it ? How to add an image to a JPanel without using the ImageIcon class ? Edit: A more careful examination of the tutorials and the API shows that you cannot add an ImageIcon directly to a JPanel. Instead, they achieve the same effect by setting the image as an icon of a JLabel. This just doesn't fill right...

  • How to use Haar wavelet to detect LINES on an image?

    - by Ole Jak
    So I have Image like this I want to get something like this (I hevent drawn all lines I want but I hope you can get my idea) I want to use SURF ( (Speeded Up Robust Features) is a robust image descriptor, first presented by Herbert Bay et al. in 2006 ) or something that is based on sums of 2D Haar wavelet responses and makes an efficient use of integral images for finding all straight lines on image. I want to get relative to picture pixel coords start and end points of lines. So on this picture to find all lines between tiles and thouse 2 black lines on top. Is there any such Code Example (with lines search capability) to start from? I love C and C++ but any other readable code will probably work for me=)

  • How do I stop image spam from being uploaded to my (future) site?

    - by Pete Lacey
    I have in mind an idea for a generally accessible site that needs to allow images to be uploaded. But I'm stymied on how to prevent image spam: porn, ads in image form, etc. Assumptions: I'm assuming that the spammers are clever, even human. I'm skeptical of the efficacy of image analysis software. I do not have the resources to approve all uploads manually. I am willing to spend money on the solution -- within reason. This site will be location-aware, if that helps. How does Flickr do it or imgur? Or do they?

  • Scaling an image in a scroller resizes the scroller when relative dimension are set to the scroller

    - by tit
    Hi, I would like to position relatively a scroller in my application like below. When I scale the image, I resize the scroller... <s:Scroller width="50%" height="50%" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> If I set absolute dimension to the scroller like below, it does not resize (behaviour I want) <s:Scroller width="400" height="400" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> .. but my intention is to position the scroller relatively to other components. Any explanations/solutions? Thanks

  • Workaround for Outlook 2007 for wrapping text around image with margin?

    - by DavidW
    As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

  • PHP: creating a smooth edged circle, image or font?

    - by Chad Whitaker
    I'm making a PHP image script that will create circles at a given radius. I used: <?php imagefilledellipse ( $image, $cx, $cy, $w, $h, $color ); ?> but hate the rough edges it produces. So I was thinking of making or using a circle font that I will output using: <?php imagettftext ( $image, $size, $angle, $x, $y, $color, 'fontfile.ttf', $text ); ?> So that the font will produce a circle that has a smooth edge. My problem is making the "font size" match the "radius size". Any ideas? Or maybe a PHP class that will produce a smooth edge on a circle would be great! Thank you.

  • My image does not load on a jQuery fade in effect even though the div loads.

    - by Konstantin
    jQuery(document).ready(function() { if (useMSIE){ pngfixALL(); }; jQuery(div).show(data_fadeInEffect, 500);return false; // jQuery(div).animate({opacity:1}, 500, 'linear'); }); This is what I have for a fade in effect. When using animate(), the image in the div tag fades in fine. However, when I use show(), the div loads because I can click in that area, but the image itself doesn't load. Why is this happening? I have another area of the code where I click on an 'x' in the image and it fades out using hide(). This works fine.

  • How to change the image by click keyboard arrows?

    - by Nitz
    Hey Guys, I have made one project in java. Now in this particular module, i am showing the user , so i am showing them a stock inventory. Now for doing this. As you will see in the screen shot [ i have put screenshot so you can understand well ]. To show the images , i have made one table and i have put labels in that and then i am setting the icon at the label. Now as soon as user click on the any image, then that image i put on big label. But this works perfect on mouse click but client want that , if user navigate the by keyboard arrow keys then in same should be happen. Means : User navigate by key board then it should reflect on that table [user should know that which is currently seleted ] and then as soon as the user navigate by key board arrow events and then click enter then that image should reflect on big label. Here is the Link for that screenshot.

  • Most optimal way to detect if black (or any color pixels) exist in an image file?

    - by Zando
    What's the best and most flexible algorithm to detect any black (or colored pixel) in a given image file? Say I'm given an image file that could, say, have a blue background. And any non blue pixel, including a white pixel, is counted as a "mark". The function returns true if there are X number of pixels that deviate from each other at a certain threshold. I thought it'd be fastest to just simply iterate through every pixel and see if its color matches the last. But if it's the case that pixel (0,0) is deviant, and every other pixel is the same color (and I want to allow at least a couple deviated pixels before considering an image to be "marked), this won't work or be terribly efficient.

  • Why is my background image not displaying properly in IE7?

    - by JAG2007
    Screenshot of the issue: here Webpage in Question: http://cure.org Offending browser: Internet Explorer 7 You'll notice from the screenshot, or if you view this site in IE7, that the background image is not displaying for the content div (#modal-inner-content). Strangely, the image displays in the other divs where it is used (since it's a sprite, I'm using that same image for #modal-top-border and #modal-btm-border). In all other browsers it displays properly, and even in IE8. I cannot seem to find what CSS rule (or lack thereof) I may be using that IE7 is choking on. NOTE: in order to get the modal screen, just click the link at the very top banner of the page that says "login to your CURE account

  • Rotating an image in all browsers (canvas in IE?)

    - by Tom
    I finally got to work with canvas only to find out that it is not implemented in IE. I tried explore canvas from google to use it in Internet Explorer, but it's not working for my code (http://uptowar.com/test.php - little bug though that it is not removing the old image when rotating). So, is there an other way to smoothly rotate an image around it's bottom center angle? Maybe javascript? Or is there a way to do it with IE and canvas anyway? Edit: Google Chrome also seems to add an ugly border to the canvas example.. there must be an other smooth way? Edit2: tried a hacky javascript way: it causes mayor lags and corrupts the image (http://uptowar.com/test2.php), anyone knows of a working method?

  • Show different product image in new.phtml vs. list

I need this to work only in new.phtml file, and not in the list.phtml.

  • What size should the background image in an MSI be?

    - by r_
    I am trying to create a Windows Installer package using Wix. I'm getting a lot of conflicting information about what size my custom background should be--the Wix documentation suggests a size of 500 x 314 pixels, but this leads to slight image distortion in the installer. I believe that I may be indirectly using the SplashBitmap property in Windows Installer, whose documentation suggests 480 x 320 is the correct size. When I try to use this image size, I also get artefacts in the image. Could anyone tell me what the correct size should be?

  • Choosing a VS project type (C++)

    - by typoknig
    Hi all, I do not use C++ much (I try to stick to the easier stuff like Java and VB.NET), but the lately I have not had a choice. When I am picking a project type in VS for some C++ source I download, what project type should I pick? I had just been sticking with Win32 Console Applications, but I just downloaded some code (below) that will not work right even when it compiles with out errors. I have tried to use a CLR Console Application and an empty project too, and have changed many variables along the way, but I cannot get this code to work. I noticed that this code does not have "int main()" at its beginning, does that have something to do with it?

  • Looking for mass cropping software

    - by Bart van Heukelom
    I'm looking for a tool than runs on Ubuntu that can let me: Open an image in a folder which has thousands Crop and rotate it Save as a copy, automatically named (not manually), with one click. Preferably with something in the name that I can later use to filter these cropped copies in Nautilus (unless it saves in another directory, that'd be even better). Move to next image and repeat Does it exist?

  • Uploading images to a post like on the stackexchange websites [on hold]

    - by Loko
    Stackexchange uses imgur link to show the image to their website, but how do I do this? I am really curious on what ways I can upload an image to a file and show it immediatly again. Like webshops where you can post your products are also uploading images to show them immediatly. What way are there to do this and what is the best / most secure?(I assume how stackexchange does it), but I also have no idea how to do that.
