  • How to load image data from resource bitmap file for directshow filter ?

    - by Forrest
    I need put one bitmap image to my directshow filter. Then user can use this bitmap image and do not care where is it. First, I import this bitmap file into resource bundle, and get one IDB_BITMAP1. Then, I need to read this IDB_BITMAP1 using opencv cvLoadImage or some windows image API to load this image into buffer. So question is how to do this ? Or is that possible ? Thanks

  • How does one smooth an image used as a control skin?

    - by kevmoo
    I'm embedding an image like this: [Embed(source="/tool_deleteUp.png")] private static const c_deleteButton_styleUp:Class; I'm using it like this: _removeButton = new Button(); _removeButton.setStyle('upSkin', c_deleteButton_styleUp); When I rotate the button, the image doesn't scale smoothly. I know the tricks one uses to scale an image loaded in an Image control, but I'm banging my head against a wall trying to figure out how to do it here. Help!

  • In an iPhone app, is it beneficial to tile a background image that has a pattern in it?

    - by Dr Dork
    Here's an example of the type of background image I'm talking about, the iPhone Notes app... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

  • How do I disable auto- poster image generation on the video tag?

    - by ekallevig
    I'm using the 'poster' attribute on a video tag and the way it seems to work at least in webkit browsers is that it loads the poster image and then once enough of the video has loaded, it replaces that poster with an auto-generated poster from the video file itself. However, my poster images don't match the auto-generated posters which results in a weird experience of one image loading, then being replaced in a few seconds by the auto-generated image. Is there any way to prevent the auto-generated image from being used?

  • How to draw image in memory manually in pyglet?

    - by Mossen
    In pyglet, I want to create an image buffer in memory, then set the bytes manually, then draw it. I tried making a 3x3 red square like this in my draw() function: imageData = pyglet.image.ImageData(3, 3, 'RGB', [1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0 ]) imageData.blit(10, 10) ...but at runtime, Python complains: ctypes.ArgumentError: argument 9: <type 'exceptions.TypeError'>: wrong type Is this the right approach? Am I missing a step? How can I fix this?

  • Anyone know how to get an LTSP image working with VIA VX855 chipset?

    - by Bryan
    I'm running an LTSP server on Ubuntu 11.10 and can load the i386 image via PXE boot on a VirtualBox VM just fine. However, when I PXE boot a Dell FX130 thin client on the LTSP network the login screen ends up being a white screen with a bunch of wavy black lines going up and down it. The 11.10 splash screen displays just fine as the image is booted, then I get a "INVALID CARD NUMBER" message, then a black screen, then finally the white screen with wavy lines. I'm not sure if the "INVALID CARD NUMBER" message has anything to do with the issue, but in the end the white screen with wavy lines makes me think it's a video driver problem. On the LTSP server, I chrooted into /opt/ltsp/i386 and made sure xserver-xorg-video-openchrome was installed. I did notice that no xorg.conf exits in /etc/X11 though.

  • How to make a disk image and restore from it later?

    - by Torben Gundtofte-Bruun
    I'm a new Linux user. I've reinstalled my Wubi from scratch at least ten times the last few weeks because while getting the system up and running (drivers, resolution, etc.) I've broken something (X, grub, unknowns) and I can't get it back to work. Especially for a newbie like me, it's easier (and much faster) to just reinstall the whole shebang than try to troubleshoot several layers of failed "fixing" attempts. Coming from Windows, I expect that there is some "disk image" utility that I can run to make a snapshot of my Linux install (and of the boot partition!!) before I meddle with stuff. Then, after I've foobar'ed my machine, I would somehow restore my machine back to that working snapshot. What's the Linux equivalent of Windows disk imagers like Acronis True Image or Norton Ghost? Note: I found a similar question here.

  • How can I convert an image from raw data in Android without any munging?

    - by stephelton
    I have raw image data (may be png, jpg, ...) and I want it converted in Android without changing its pixel depth (bpp). In particular, when I load a grayscale (8 bpp) image that I want to use as alpha (glTexImage() with GL_ALPHA), it converts it to 16 bpp (presumably 5_6_5). While I do have a plan b (actually, I'm probably on plan 'e' by now, this is really becoming annoying) I would really like to discover an easy way to do this using what is readily available in the api. So far, I'm using BitmapFactory.decodeByteArray(). While I'm at it. I'm doing this from a native environment via jni (passing the buffer in from C, and a new buffer back to C from Java). Any portable solution in C/C++ would be preferable, but I don't want to introduce anything that might break in future versions of Android, etc.

  • Foolproof way to ensure Google news pulls the correct image for it's thumbnails?

    - by Anthony
    Google news results have an acompanying thumbnail next to articles that show up in the results. If google's crawler can't find a thumbnail to pull from our site, it uses its next best guess from another site, therefore linking the image to another site but still uses our headline. Example: Headline from Reuters, Image from Livemint: Our pages absolutely have images, they are not massive in file-size or dimensions, yet we are not having them pulled / crawled correctly. We have read up on the suggestions from google, and from others around the web and nothing is panning out. Has anyone had any experience where they can ensure google news will pull a thumbnail of our choosing?

  • Properly create centered vertical navigation list with a hover image on both sides?

    - by Damainman
    I have a navigation list I placed inside of a , I am attempting to get an image that appears on both sides of a link when you hover. Basically a an arrow on each side of the link. I have managed to get the effect I am looking for with: <ul> <li style=""> <a href="#">Services</a> </li> <li> <a href="#">About</a> </li> <li> <a href="#">Media</a> </li> <li> <a href="#">FAQ</a> </li> <li> <a href="#">Portfolio</a> </li> <li> <a href="#">Contact</a> </li> </ul> .nav ul{ list-style:none; text-align:center; } .nav li:hover a:before, .nav li:hover a:after { content:url(../images/nav_bullet.png); } The end result will look like the following but with the list centered: link >> Hovered Link << link However I am not sure if that is the best way of going about it, and the image is too close to the text. I tried placing a margin and padding but that didn't work. To top of it off, the image is not vertically centered with the link text. Anyone know of a proper way to do this as I am just going by trial and error? Thank you in advance!

  • Is it possible to use the Raring install image as a package repo (like the old alternate CD)?

    - by jamadagni
    I use Kubuntu and recently upgraded to Raring directly from Precise. Until Precise, I always installed the OS using the alternate CD and not the desktop CD, because I could later on mount the image and use it as an offline package repo. For instance if I remove a package installed by the default installer and later I want to install it again, I can just install it from the ISO without needing to download it again. However, since Quantal the alternate CD no longer exists, so I am not sure how to set up the installed image as a local repo. I mean, doing find . -name "*.deb" inside the ISO tree after loopmounting it only shows a few packages like libc6 gcc and such and not the full set of packages that are actually installed -- I presume they are included in pre-installed form inside casper/filesystem.squashfs. Given this situation, is it or is it not possible to use the Raring install images as offline repos? If yes, how? Thank you!

  • How to determine edges in an images optimally?

    - by SorinA.
    I recently was put in front of the problem of cropping and resizing images. I needed to crop the 'main content' of an image for example if i had an image similar to this: the result should be an image with the msn content without the white margins(left& right). I search on the X axis for the first and last color change and on the Y axis the same thing. The problem is that traversing the image line by line takes a while..for an image that is 2000x1600px it takes up to 2 seconds to return the CropRect = x1,y1,x2,y2 data. I tried to make for each coordinate a traversal and stop on the first value found but it didn't work in all test cases..sometimes the returned data wasn't the expected one and the duration of the operations was similar.. Any idea how to cut down the traversal time and discovery of the rectangle round the 'main content'? public static CropRect EdgeDetection(Bitmap Image, float Threshold) { CropRect cropRectangle = new CropRect(); int lowestX = 0; int lowestY = 0; int largestX = 0; int largestY = 0; lowestX = Image.Width; lowestY = Image.Height; //find the lowest X bound; for (int y = 0; y < Image.Height - 1; ++y) { for (int x = 0; x < Image.Width - 1; ++x) { Color currentColor = Image.GetPixel(x, y); Color tempXcolor = Image.GetPixel(x + 1, y); Color tempYColor = Image.GetPixel(x, y + 1); if ((Math.Sqrt(((currentColor.R - tempXcolor.R) * (currentColor.R - tempXcolor.R)) + ((currentColor.G - tempXcolor.G) * (currentColor.G - tempXcolor.G)) + ((currentColor.B - tempXcolor.B) * (currentColor.B - tempXcolor.B))) > Threshold)) { if (lowestX > x) lowestX = x; if (largestX < x) largestX = x; } if ((Math.Sqrt(((currentColor.R - tempYColor.R) * (currentColor.R - tempYColor.R)) + ((currentColor.G - tempYColor.G) * (currentColor.G - tempYColor.G)) + ((currentColor.B - tempYColor.B) * (currentColor.B - tempYColor.B))) > Threshold)) { if (lowestY > y) lowestY = y; if (largestY < y) largestY = y; } } } if (lowestX < Image.Width / 4) cropRectangle.X = lowestX - 3 > 0 ? lowestX - 3 : 0; else cropRectangle.X = 0; if (lowestY < Image.Height / 4) cropRectangle.Y = lowestY - 3 > 0 ? lowestY - 3 : 0; else cropRectangle.Y = 0; cropRectangle.Width = largestX - lowestX + 8 > Image.Width ? Image.Width : largestX - lowestX + 8; cropRectangle.Height = largestY + 8 > Image.Height ? Image.Height - lowestY : largestY - lowestY + 8; return cropRectangle; } }

  • Upload file in Android webview

    - by Sunny
    I have a html form like this <form data-ajax="false" action='UserPhoto.php' class="settings" method='POST' enctype='multipart/form-data' > <input type='file' style="height:25px" name='photo' /> <input type='hidden' name='task' value='upload'> <input type='hidden' name='file_size' value='5000000'> and I want to upload it by using webView posturl function, is it possible? as I know posturl can send String data by this way String value1 = "persistent=1"; String value2 = "&email="+ 2nd_value; String value3 = "&password="+ 3rd_value; String postData = value1+value2+value3; webView.postUrl("http://www.abc.php",EncodingUtils.getBytes(postData, "BASE64")); but is it possible for me to post .png together with some string values? and I know another method using this way to upload photo conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("ENCTYPE", "multipart/form-data"); conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); conn.setRequestProperty("photo", fileName); but this way doesn't communicate with webview, I need to post the photo using webview as user session is kept with it. Thanks for helping.
