  • Bitmap manipulation in C++ on Windows

    - by Oliver
    Hi, I have myself a handle to a bitmap, in C++, on Windows: HBITMAP hBitmap; On this image I want to do some Image Recognition, pattern analysis, that sort of thing. In my studies at University, I have done this in Matlab, it is quite easy to get at the individual pixels based on their position, but I have no idea how to do this in C++ under Windows - I haven't really been able to understand what I have read so far. I have seen some references to a nice looking Bitmap class that lets you setPixel() and getPixel() and that sort of thing, but I think this is with .net . How should I go about turning my HBITMAP into something I can play with easily? I need to be able to get at the RGBA information. Are there libraries that allow me to work with the data without having to learn about DCs and BitBlt and that sort of thing?

  • iOS and Infrared

    - by Mustafa
    Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)? Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how? What are the limitations and requirements? What kind of additional hardware is required? If it's available in the market? Which protocols should i know about? Which iOS libraries can help me in the process. Can anyone point me in the right direction. Thanks.

  • Ubuntu on Samsung NP700Z5B - no Grub

    - by copolii
    I just bought a Samsung NP700Z5B laptop. Gorgeous machine and great performance! I do 2 things when I get a new laptop: Format the HD and install Winblows from a CD to ditch the bloatware Install some variant of Linux on it (lately Ubuntu) Step 1 worked fine (until earlier today), but I haven't been able to install Ubuntu on it for the past 3 days! I've tried Mint12, Ubuntu 12.04, Ubuntu 11.10, Ubuntu 11.04 and Ubuntu 10.04. The live CD and the installations all run fine and report no problems, but when I reboot grub is nowhere to be found! The system goes directly to Winblows! I've tried booting from the liveCD and re-installing grub via the chroot and purge & reinstall methods (https://help.ubuntu.com/community/Grub2) and neither makes a difference. I've also tried copying the boot sector: dd if=/dev/sda of=linux.bin bs=512 count=1 and putting it on c: then setting bcdedit to add the entry to the Windows bootloader with no results. Earlier today I decided to try and set my boot partition as an EFI boot partition ... bad choice, now I don't even have the Winblows boot loader. I've officially ran out of ideas. Tried calling Samsung, but they're closed (they'd probably say something stupid along the lines of "Samsung recommends Windows 7" ... I've had Dell say that to me). Any help would be greatly appreciated. Update 1 Tried re-installing 12.04 and now I get the screen continously turning off and back on, but still no sign of booting ... it has been doing it for 15 mins so far (I set the boot partition type to ext2 instead of ext4) Update 2 Well ... this just gets better and better. I inserted the installation USB key to reboot it and the flickering stopped for about a minute (remained on) then it started turning off and on again

  • Windows 8.1 - unfixable grub

    - by Nick
    I have a Gigabyte laptop that came with secure boot and windows 8. After a bit of battling, I managed to get my dual boot with Ubuntu 13.10.. Anyway, I upgraded zindows to 8.1, now grub is gone. I restarted from a live CD and chrooted to my drive. I used boot-repair multiple times (with successful output) both in default and with some advanced options; also reinstalled grub manually... Each time it tries once to boot to grub but gives a message for a very short amount of time. I recorded it and it is a regular bios message "Rebbot and Select proper Boot device of Insert Boot media in selected boot device and press a key" I even tried something called EasyBCD under winblows, it shows the correct boot options, but same there, it is unable to make the linux partition fire up. Anyway, no way to boot my linux box. Does anyone have an idea how to fix this? No need to redirect me to another post with grub reinstall or boot-repair, seen them all... I am thinking of trying this other boot loader, refind, to see if it works http://www.rodsbooks.com/refind/index.html Also re-reading this bios message, I'm thinking my partition might not have a boot flag anymore... I'll try that too with parted. Although both grub and win 8 are supposed to fire up from the same boot partition (the EFI one) Please help! thx

  • release vs setting-to-nil to free memory

    - by Dan Ray
    In my root view controller, in my didReceiveMemoryWarning method, I go through a couple data structures (which I keep in a global singleton called DataManager), and ditch the heaviest things I've got--one or maybe two images associated with possibly twenty or thirty or more data records. Right now I'm going through and setting those to nil. I'm also setting myself a boolean flag so that various view controllers that need this data can easily know to reload. Thusly: DataManager *data = [DataManager sharedDataManager]; for (Event *event in data.eventList) { event.image = nil; event.thumbnail = nil; } for (WondrMark *mark in data.wondrMarks) { mark.image = nil; } [DataManager sharedDataManager].cleanedMemory = YES; Today I'm thinking, though... and I'm not actually sure all that allocated memory is really being freed when I do that. Should I instead release those images and maybe hit them with a new alloc and init when I need them again later?

  • Animating UIImageView iPhone

    - by Fred Dpn
    Hi, i'm having trouble about animating an Image in a UIImageView. I've created an image view in interface builder and linked it to its iboutlet. Here is my code. @interface Game : UIViewController <UIAccelerometerDelegate>{ IBOutlet UIImageView *diying; } @property (nonatomic, retain) UIImageView *diying; In the viewDidLoad method i've written this code NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"Die1.gif"], [UIImage imageNamed:@"Die2.gif"], [UIImage imageNamed:@"Die3.gif"], [UIImage imageNamed:@"Die4.gif"], nil]; diying.animationImages = imageArray; diying.animationDuration = 1.1; diying.contentMode = UIViewContentModeBottomLeft; [diying startAnimating]; [super viewDidLoad]; which is a adaptation of what i've found here : http://icodeblog.com/2009/07/24/iphone-programming-tutorial-animating-a-game-sprite/ NB : those .gif files are simple images and are not animated. I did the tutorial and it worked fine but i can't figure out why it my adaptation doesn't work !

  • Documenting and defining content types for a CMS or similar project

    - by Rimian
    I'm writing up some documentation on a Drupal project and my task is to define the content types and their attributes. The intended audience is project managers and developers. So it could be a high level document that gives an overview of the system. (I think that's how I describe it: high level rather than high detail) At the moment I'm using open office and bullet points but it seems like an amateurish method when I need to describe details that could be useful for a developer (me). Something like UML would describe detail but is probably more complicated than I need right now and could be too technical for others on the team. Are there any universal methods or templates that I can use to describe information in this case?

  • How can I embed a conditional comment for IE with innerHTML?

    - by Samuel Charpentier
    Ok so I want to conditionally add this line of code; <!--[if ! IE]> <embed src="logo.svg" type="image/svg+xml" /> <![endif]--> Using: document.getElementById("logo") .innerHTML='...'; In a if()/else() statement and it don't write it! If i get rid of the selective comment ( <!--[if ! IE]><![endif]-->) and only put the SVG ( <embed src="logo.svg" type="image/svg+xml" /> ) it work! what should I do? I found a way around but i think in the Android browser the thing will pop up twice. here's what I've done ( and its Validated stuff!); <!DOCTYPE html> <html> <head> <META CHARSET="UTF-8"> <title>SVG Test</title> <script type="text/javascript"> //<![CDATA[ onload=function() { var ua = navigator.userAgent.toLowerCase(); var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile"); if(isAndroid) { document.getElementById("logo").innerHTML='<img src="fin_palais.png"/>'; } } //]]> </script> </head> <body> <div id="logo"> <!--[if lt IE 9]> <img src="fin_palais.png"/> <![endif]--> <!--[if gte IE 9]><!--> <embed src="fin_palais.svg" type="image/svg+xml" /> <!--<![endif]--> </div> </body>

  • Mac OSX: Passing a file from user process to kernel module.

    - by Inso Reiges
    Hello, I need to pass a link to file from a user process to the OSX kernel driver. By link i mean anything that uniquely identifies a file on the local filesystem. I need that link to do I/O on that file in kernel. The most obvious solution seems to pass a file name and use a VFS vnode lookup. However i noticed, that Apple Disk Images helper process passes a raw data array for image-path property to driver when attaching a disk image file: <2f 56 6f 6c 75 6d 65 73 2f 73 74 6f 72 61 67 65 2f 74 65 73 74 32 2e 64 6d 67> What is that diskimages-helper passes to the kernel driver? Some serialized type perhaps? If yes, what type is it and how can i use it?

  • Re-measuring custom item renderer on a List

    - by leolobato
    I'm writing an Adobe Air client to a service similar to Twitter. On the timeline (List component) I have a custom item renderer which is basically a Canvas with a fixed-width Image and a Text control, which is multi-line. If the text is long enough to change the Canvas height, it will only be resized if I manually change the width of the Window, forcing a redraw of all renderers. If I simply scroll through the List, all "new" renderers will have the minimum height possible (which is the Image height). Any ideas on how to force the re-measurement of the renderer when I set it's data? Thanks in advance! :)

  • Bitmap Confusion Android

    - by Farhan
    I am getting an image from gallery in onActivityResult() through intent.getdata(). Now i get the data and set it to a bitmap, its size is 716x716 and its setting to full screen. (ImageView's width and height is set to wrap content). Now i created another bitmap after scaling the original through Bitmap.CreateScaledBitmap(orgBitmap,30,30,false); After this, i make sure these things(width,height n size) and they happen as they should be but the problem is that the image is still taking the full screen... rather it should only take 30dp x 30dp. Anyone have an idea what might be the problem??? Thanx

  • Load a bitmap from file in RGB format (without alpha)

    - by Robert
    Hi, i simply want to load a .BMP file and get the Bitmap object in 24bit RGB format (or 32bit in RGB format). All methods I tried return a Bitmap/Image object with PixelFormat = Format32bppArgb. Even if of course BMPs don't have alpha. new Bitmap(System.Drawing.Image.FromFile(fileName, true)); new Bitmap(fileName); I currently solve the problem by copying the first object to another in memory bitmap at 24bit RBG. Is there a single method to do it? Thanks

  • Jquery code working in all browsers apart from FF

    - by alan
    Hi, I have written the following jquery sitting in the head tags of my HTML It is supposed to bring the image that is being hovered over to full opacity and slide another image over it from the right, then return when un-hovered. <script type="text/javascript"> $(function() { $('ul#img-nav li').css({ "opacity": .5 }); $('ul#img-nav li').hover(function() { $(this).stop(true).animate({"opacity":1}); $(this).children('.overlay').stop(true).animate({"left" : "18px" }); }, function() { $(this).stop(true).animate({"opacity":.5}); $(this).children('.overlay').stop(true).animate({"left" : "180px" }); }); }); This works fine in Safari, Chrome, IE (7,8) but not in FF 3.6. Any suggestions why this might be? Many thanks

  • setNeedsDisplayInRect: paints a white rectangle only

    - by Ion Tichy
    Hi, I'm still a little fresh to CoreGraphics programming, so please bear with me. I'm trying to write an application, which allows the user to rub stuff off an image with the finger. I have the basic functionality nailed down, but the result is sluggish since the screen is redrawn completely every time a touch is rendered. I did some research and found out that I can refresh only a portion of the screen using UIView's setNeedsDisplayInRect: method. This does call drawRect: as expected, however everything I draw in the drawRect: following the setNeedsDisplayInRect: is ignored. Instead, the area in the rect parameter is simply filled with white. No matter what I draw inside, all I end up with is a white rectangle. In essence, this is what I do: 1) when user touches screen, this touch is rendered into a mask 2) when the drawRect: is called, the image is masked with that mask There must be something simple I'm overlooking, surely?

  • Five years old Ubuntu system - dist-upgrades always went fine, however some tasks remain

    - by knb
    I have a PC with a current Ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kind of left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

  • Captcha Alternative, how secure?

    - by aslum
    I do the web page for my local library, and I was thinking it might be kind of appealing to have a "custom" captcha based on book covers. So serve up one of several dozen book covers, and have the patron filling out the form type the book title to prove they're human. Assuming I stripped the title/author info from the image and filename, would that be enough? Would the fact that it was a unique system on a fairly small website be enough to make it effective? Just how tricky are the spam bots these days? Would having the image name be the ISBN # be too obvious?

  • How to set up a Bitmap with unmanaged data?

    - by Danvil
    I have int width, height; and IntPtr data; which comes from a unmanaged unsigned char* pointer and I would like to create a Bitmap to show the image data in a GUI. Please consider, that width must not be a multiple of 4, i do not have a "stride" and my image data is aligned as BGRA. The following code works: byte[] pixels = new byte[4*width*height]; System.Runtime.InteropServices.Marshal.Copy(data, pixels, 0, pixels.Length); var bmp = new Bitmap(width, height, System.Drawing.Imaging.PixelFormat.Format32bppArgb); for(int i=0; i<height; i++) { for(int j=0; j<width; j++) { int p = 4*(width*i + j); bmp.SetPixel(j, i, Color.FromArgb(pixels[p+3], pixels[p+2], pixels[p+1], pixels[p+0])); } } Is there a more direct way to copy the data?

  • Possibility to introduce iPad capability for iPhone-App via Update?

    - by samsam
    Hi there. There has been a lot of talk around iPad-Apps / Approval / Store-related Questions. I've recently built an App which I'm just about to release / send to Apple for approval. I'm thinking about developing a dedicated iPad-App as well. Now, in order to not have two seperate Apps in the Store (one for the iPhone, one for the iPad) i want to create an universal-App for both platforms. However, i couldn't figure out if it is possible to first send in my iPhone-only app and later publish an update that enables my app to run on both platforms. Does anyone have an idea on that topic? thanks in advance sam
