  • Progressively transparent image with CSS3?

    - by Teiviere
    I want images that gradually "gradient" to blend in with the background color (white/transparent) as it gets to the bottom. Is there a way I can apply a CSS3 gradient or some sort of gradual transparency using CSS3 to the bottom edges of the image so it looks like its fading into the background color? I know I can make images with some photoeditor to achieve that effect, but I am curious to know if CSS3 can accomplish it.

  • what firefall linux distro applicance could track internet usage per device in my home?

    - by GregH
    Hello, Anyone know of a community edition/open source/free firewall/gateway software product that I could install onto an old PC to act as my firewall/gateway/proxy etc, BUT for which it has the power to track internet usage per device in my home. So: a) Mandatory - Track internet usage for devices on my home network on a per device basis (e.g. various PCs/Xbox etc) b) Mandatory - Report/graph would would give a breakdown of internet usage, per device (e.g. IP address), per day. c) Desirable - as in b) above but per hour d) Desirable - realtime graph (e.g. 5 minute measurement intervals or something) that shows current internet usage per device e) Mandatory - Handles all internal<=internet requests for all protocols (e.g. HTTP, HTTPS, xbox etc) f) Mandatory - No explicit settings in clients required - i.e. Transparent Monitoring concept (for both HTTP and non-HTTP traffic like xbox, skype etc) g) Mandatory - easy "appliance" like installation onto a dedicated low spec PC thanks in advance

  • Multi-monitor aterm transparency

    - by Bryan Ward
    I have 3 monitors which I set the background with using xpmroot my-5760x1200bg.png I then setup aterm to use transparency by adding the following to my ~/.Xdefaults file. aterm*transparent:true aterm*shading:60 aterm*background:Black aterm*foreground:White aterm*scrollBar:true aterm*scrollBar_right:true aterm*transpscrollbar:true aterm*saveLines:32767 aterm*font:*-*-fixed-medium-r-normal--*-140-*-*-*-*-iso8859-1 aterm*boldFont:*-*-fixed-bold-r-normal--*-*-140-*-*-*-*-iso8859-1 I am getting transparency on my aterm windows, but the image that is coming through with the transparency isn't correct. On the left monitor things are fine, but the middle and right monitors both seem to use the leftmost 1920x1200 of the background image as what is behind the terminal window. It would be as if every screen had the same background as the monitor on the left. Is this something that can be configured to be correct, or is this a bug? I'm running Gentoo Linux with Xmonad.

  • Proxy server modifying request/response upon pass through

    - by jamiei
    I would like to set up a non-transparent proxy server that will selectively modify HTTP requests and responses as it passes them through. The motivation for wanting to modify the data on the fly and not at the original source are not part of the question. I'm hoping there is a solution which allows the modification scripts to be written in a mainstream programming language. I am aware of guides for Squid which allow you to flip images etc on the way through but I was hoping for a slightly more established and less hackish solution. Does anyone know of an established open source project or environment (Any major platform) which would allow me to script in arbitrary modifications to the data being passed through?

  • Taking screenshots in Windows Vista, Windows 7, with transparent areas outside the app region

    - by Steve Sheldon
    Hey Folks, I am trying to take a screenshot of an application and I would like to make the parts of the rectangle that are not part of the applications region be transparent. So for instance on a standard windows application I would like to make the rounded corners transparent. I wrote a quick test application which works on on XP (or vista/windows 7 with aero turned off): protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); Graphics g = e.Graphics; // Just find a window to test with IntPtr hwnd = FindWindowByCaption(IntPtr.Zero, "Calculator"); WINDOWINFO info = new WINDOWINFO(); info.cbSize = (uint)Marshal.SizeOf(info); GetWindowInfo(hwnd, ref info); Rectangle r = Rectangle.FromLTRB(info.rcWindow.Left, info.rcWindow.Top, info.rcWindow.Right, info.rcWindow.Bottom); IntPtr hrgn = CreateRectRgn(info.rcWindow.Left, info.rcWindow.Top, info.rcWindow.Right, info.rcWindow.Bottom); GetWindowRgn(hwnd, hrgn); // fill a rectangle which would be where I would probably // write some mask color g.FillRectangle(Brushes.Red, r); // fill the region over the top, all I am trying to do here // is show the contrast between the applications region and // the rectangle that the region would be placed in Region region = Region.FromHrgn(hrgn); region.Translate(info.rcWindow.Left, info.rcWindow.Top); g.FillRegion(Brushes.Blue, region); } Quick side note: before commenting that this code is doing stuff it shouldn't (or should do, like dispose) in a paint function, I know, it's not going anywhere but this post and is designed purely as a way to quickly show the problem, and that it does... OK, back to the problem ;) When I run this test app on XP (or Vista/Windows 7 with Aero off), I get something like this, which is great because I can eek an xor mask out of this that can be used later with BitBlt. Here is the problem, on Vista or Windows 7 with Aero enabled, there isn't necessarily a region on the window, in fact in most cases there isn't. Can anybody help me figure out how to get the region of the application like this on these platforms. Here are some of the approaches I have already tried... 1. Using the PrintWindow function: This doesn't work because it gives back a screenshot taken of the window with Aero off and this window is a different shape from the window returned with Aero on 2 Using the Desktop Window Manager API to get a full size thumbnail: This didn't work because it draws directly to the screen and from what I can tell you can't get a screenshot directly out of this api. Yeah, I could open a window with a pink background, show the thumbnail, take a screenshot then hide this temporary window but thats a horrible user experience and a complete hack I would rather not have my name on. 3. Using Graphics.CopyFromScreen or some other pinvoke variant of this: This doesn't work because I can't assume that the window I need information from is at the top of the z-order on the screen. Right now, the best solution I can think of is to special case Aero on Windows 7 and Vista to manually rub out the corners by hard coding some graphics paths I paint out but this solution would suck since any application that performs custom skinning will break this. Can you think of another or better solution? If you are here, thanks for taking time to read this post, I appreciate any help or direction that you can offer!

  • Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

    - by ultrasawblade
    I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

  • Can I use iptables on my Varnish server to forward HTTPS traffic to a specific server?

    - by Dylan Beattie
    We use Varnish as our front-end web cache and load balancer, so we have a Linux server in our development environment, running Varnish with some basic caching and load-balancing rules across a pair of Windows 2008 IIS web servers. We have a wildcard DNS rule that points *.development at this Varnish box, so we can browse http://www.mysite.com.development, http://www.othersite.com.development, etc. The problem is that since Varnish can't handle HTTPS traffic, we can't access https://www.mysite.com.development/ For dev/testing, we don't need any acceleration or load-balancing - all I need is to tell this box to act as a dumb proxy and forward any incoming requests on port 443 to a specific IIS server. I suspect iptables may offer a solution but it's been a long while since I wrote an iptables rule. Some initial hacking has got me as far as iptables -F iptables -A INPUT -p tcp -m tcp --sport 443 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 443 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 443 -j DNAT --to 10.0.0.241:443 iptables -t nat -A POSTROUTING -p tcp -d 10.0.0.241 --dport 443 -j MASQUERADE iptables -A INPUT -j LOG --log-level 4 --log-prefix 'PreRouting ' iptables -A OUTPUT -j LOG --log-level 4 --log-prefix 'PostRouting ' iptables-save > /etc/iptables.rules (where 10.0.0.241 is the IIS box hosting the HTTPS website), but this doesn't appear to be working. To clarify - I realize there's security implications about HTTPS proxying/caching - all I'm looking for is completely transparent IP traffic forwarding. I don't need to decrypt, cache or inspect any of the packets; I just want anything on port 443 to flow through the Linux box to the IIS box behind it as though the Linux box wasn't even there. Any help gratefully received... EDIT: Included full iptables config script.

  • Setting my PictureBox to transparent background color doesn't really make it transparent. Bug?

    - by Sergio Tapia
    Here's what I have in VERY simple easy to grasp terms. My form background is Blue. I created a gradient image from white to the Blue from the form background. This is to give the form a nice gradient look. I added a picturebox to my Form and set this image as the Image. I added a picturebox with a Logo on top of the gradient Picturebox, but it's 'grabbing' the Form background color and not respecting the transparent background image I wanted it to grab. So: Blue Form - Huge pictureBox with gradient - Small picturebox thats supposed to respect the gradient. Help please!

  • Add transparent JPanel upon AWT Component to paint on

    - by Gambrinus
    Hi, I've got a Problem: In my Java application I've got an AWT Component (cannot change that one) that streams and shows an avi-file. Now I want to draw upon this movie and thought about putting a transparent JPanel above it and draw on that one. This does not work since I either see the avi-stream or the drawn lines but not both. I read somewhere that AWT does not support transparency of components - but the panel is a JPanel which is able to do so. Can someone please help me with this one - thanks in advance.

  • Signup form using Braintree Transparent Redirect

    - by Robin Fisher
    Hi, I'm developing an application in Rails and want the user to be able to signup and provide their card details on one form. I'm using the Braintree API and their transparent redirect, which means that the form data is posted directly to Braintree. How can I store and later retrieve the non-payment related information provided by the user from that form e.g. account name, username? These values are not returned in the response provided by Braintree. If you look at the Basecamp signup process, this is the result I want to achieve. Thanks Robin

    Hi, I want to have a alpha blended window over a video playing in the background. Considering the fact that a window cannot be made alpha blended over another window unless you take a snap of the background, I had to resort to OpenGL. I have few options for this: (1) To show an object on the WinCE window without showing the OpenGL ES window. Is it possible to do this ?? (2) Make the opengles window transparent and then show the object. Any suggestions will be greatly appreciated. Please can some1 help me by giving some inputs Thanks for any help Aditya

  • Memory-Mapped Files & Transparent Persistence of Java Objects

    - by geeko
    Greeting All, I want to achieve transparent persistence of Java objects through memory-mapped files (utilize the OS paging/swapping mechanism). My problem is: how can I move a Java object to my memory-mapped block ? Plus, how can I force a new object instance to reside in such blocks ? As you all know, a memory-mapped block can be seen as a byte array, and what I am really asking here is how to overlap the address space of Java objects with the one of such arrays ? If Java does not allow me for this, what cross-platform & garbage-collecting OO language would you advise me to use ? Thank you all in advance.

  • iPad/iPhone uiSearchbar transparent background

    - by Tom
    I know this questions was asked(and solved) before, but this wont work for me. as a matter of fact, I had it already solved, but this issue came back out of nowhere and struck me on the head. I am not able to set the background of my UISearchBar transparent. I was always using: searchBar.backgroundColor = [UIColor clearColor]; [[searchBar.subviews objectAtIndex:0] removeFromSuperview]; and it worked nicely... but suddenly it stopped. could be since I upgraded my xcode-version but I am not sure. I spent a couple of hours already investigating this.. Is somebody out there to do this? please point me in the right direction. thanks heaps!!! best regards T

  • UITableViewCell is transparent when not supposed to be

    - by David Liu
    My UITableViewCell is being transparent when it's not supposed to be. My table view has a background color and it shows through the table cell, even though they're supposed to be opaque. I'm not sure why this is. Relevant code: UITableViewCell *cell = [table dequeueReusableCellWithIdentifier:emptyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:emptyIdentifier] autorelease]; } cell.textLabel.text = @"Empty"; cell.textLabel.textAlignment = UITextAlignmentCenter; cell.textLabel.backgroundColor = [UIColor whiteColor]; return cell;

  • Create two semi-transparent images that when stacked produce the target image

    - by posfan12
    Due to CSS limitations I am forced to stack to semi-transparent images on my website. I won't go into detail regarding the CSS since if I can get this question answered the problem is moot. Anyway, I would like to modify image A in the GIMP such that it will look like it did originally after being stacked on top of image B. Both image A and image B have their opacities set to 50%. Image B is a solid color throughout, whereas image A has some minor details such as a gradient. Here's what it looks like before image B is applied on top (and what it should look like in the end): [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_target_image.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_target_image.png[/IMG][/URL] Here's what it looks like after image B has been applied on top: [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_undesired_result.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_undesired_result.png[/IMG][/URL] Thanks!

  • Transparent child control

    - by pps
    Hello all, I'm writing a control that may have some of its parts transparent or semitransparent. Basically this control shows a png image (with alpha channel). The control's parent window has some graphics on it. Therefore, to make the png control render correctly it needs to get image of what the parent window would draw beneath it. Parent dialog might have WS_CLIPCHILDREN flag set, that means that the the parent window won't draw anything under the the png control and in this case png control won't work properly. This control has to work on Windows Mobile also, so it can't have WS_EX_TRANSPARENT

  • Transparent Arc on HTML5 Canvas

    - by Rigil
    Here I have an arc with some transparency applied to one of the two gradients its using:` ctx.arc(mouseX,mouseY,radius,0, 2*Math.PI,false); var grd=ctx.createRadialGradient(mouseX,mouseY,0,mouseX,mouseY,brushSize); grd.addColorStop(1,"transparent"); grd.addColorStop(0.1,"#1f0000"); ctx.fillStyle=grd; ctx.fill(); Is there a way to now give the entire arc some transparency affecting only the arc and none of the rest of the canvas? Thanks
