  • Simple image server

    - by Joel
    I have a bunch of images that I need others to browse via a web browser in pretty much the same way as Apache-Gallery. I'd be able to dump all my images in a directory so that users hitting: http://server:port/directory would see small thumbnails and selecting an image would load it full size on a page with options to browse the previous or next image. I'm looking for a non Apache solution, much like the wonderfull Python simple http server, that can be launched anywhere with minimal configuration & fuss e.g. python -m SimpleHTTPServer 8000 In fact, the python solution above is pretty much want I want except it doesn't thumbnail the images but just a simple directory listing. Happy to use an app written in any common language so long as it is self contained and can run on linux on a custom port (and to re-iterate, not an Apache module).

  • Scale transform in xaml (in a controltemplate) on a button to perform a "zoom"

    - by Matt B
    Hi all, I've got a button with an image in it and it's being styled by the following: <ControlTemplate x:Key="IconButton" TargetType="Button"> <Border> <ContentPresenter Height="80" Width="80" /> </Border> <ControlTemplate.Triggers> <EventTrigger RoutedEvent="Button.Click"> <BeginStoryboard> <Storyboard TargetProperty="Opacity"> <DoubleAnimation From="1" To="0.5" Duration="0:0:0.5" /> <DoubleAnimation From="0.5" To="1" Duration="0:0:0.5" /> </Storyboard> </BeginStoryboard> </EventTrigger> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard> <Storyboard TargetProperty="Width"> <DoubleAnimation From="80" To="95" Duration="0:0:0.2" /> </Storyboard> </BeginStoryboard> </EventTrigger> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="Cursor" Value="Hand"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> Button is as follows: <Button Template="{StaticResource IconButton}" Name="btnExit"> <Image Source="Images/Exit.png" /> </Button> The problem is that the width doesn't change when my mouse goes over. (Or at least - the width of the image does not...) I believe there is a "scale" transform I can use to enlarge the button and all it's contents? how would I do that here...? Thanks.

  • image decoding problem in android

    - by achie
    Some of the images are not being displayed in the web browser in android while they work fine on all other machines and mobile devices. this is an example of one of those images http://s3.amazonaws.com/itriage/logos/19/iphone_list.jpg?1261515055 So I tried to pull the image to see it if it works from code. This is what I did URL url = new URL(address); InputStream is = (InputStream) url.getContent(); Drawable d = Drawable.createFromStream(is, "src"); It works for most images but for some images including this images it gives this error D/skia (28314): --- decoder-decode returned false Why is this happening and how can I prevent this. I saw an example on the developers forum but thats when we are accessing the image directly. But what I want is the browser to handle it. So how do I encode my images on my server for the android devices to recognise them correctly?

  • Getting Image size of JPEG from its binary

    - by rajeshsr
    Hi I have a lot of jpeg files with varying image size. For instance, here is the first 640 bytes as given by hexdump of an image of size 256*384(pixels): 0000000: ffd8 ffe0 0010 4a46 4946 0001 0101 0048 ......JFIF.....H 0000010: 0048 0000 ffdb 0043 0003 0202 0302 0203 .H.....C........ 0000020: 0303 0304 0303 0405 0805 0504 0405 0a07 ................ 0000030: 0706 080c 0a0c 0c0b 0a0b 0b0d 0e12 100d ................ I guess the size information mus be within these lines. But am unable to see which bytes give the sizes correctly. Can anyone help me find the fields that contains the size information?

  • Making a DVD video with a still image and PCM 16bit audio with ffmpeg

    - by João
    I'm trying to make a small video with a still image and a sound file playing in the background to pass it to dvdauthor and create a DVD. The command I'm using is this: ffmpeg -loop_input -i image.jpg -qscale 2 -i song.flac -aspect 4:3 -target pal-dvd -acodec pcm_s16le -shortest output.mpg However, the resulting video file doesn't have sound at all (testing it on VLC Player). I don't know if I can't combine "-acodec pcm_s16le" with "-target pal-dvd" to override the later, or if there is something else wrong with the command. If I try without the "-acodec pcm_s16le" parameter the video and audio works, I can even create a DVD ISO with it. However, the audio stays as AC3. I wanted to include with the video the lossless audio, not a compressed one. I suppose the DVD standart allows to have PCM audio in it, am I right?

  • How do you ensure a <td> is exactly 200px tall?

    - by George Edison
    I have a table with an image inside: <table style="border: 3px solid rgb(0, 0, 0); width: 800px; background-color: rgb(255, 255, 255); margin-left: auto; margin-right: auto; border-collapse: collapse;"> <tbody> <tr> <td style="text-align: center; padding: 0px; margin: 0px;"><img style="width: 800px; height: 200px; border: 0px;" alt="Logo" src="logo.png"> </td> </tr> </tbody> </table> No matter what I do, there is still a little sliver of white at the bottom of the image. A quick check with Chrome's Inspector reveals that the td has a height of 204px! How can I force the td to be the same height as the image? As you can see above, I've tried all sorts of things...

  • Overlay image/map on MapView?

    - by CCDEV
    Okay, hope you can help med here :) I have been searching everywhere to figure this out, but haven't had any luck. I know about Annotations and how to overlay them on a map on the iPhone. But what if I have location like in the forest where there arent any roads or anything. What I am asking is, how can I overlay a custom image (map) over the Map view so that it zooms the right way like the map, in the right scale, and can I add my own annotations on top of the custom image/map? Hop I was clear enough on what I am trying to do?

  • How to set source path of image within html pages to show in webbrowser control

    - by Royson
    Hi in my application there is web browser control to show some static html pages. The pages are displayed properly. but images are not displayed.. I tried with changing src-path but no success. my htmlpages folder is located at bin folder. And i am assigning it as. FileStream source = new FileStream(@"..\HtmlPages\supportHtml.html", FileMode.Open, FileAccess.Read); if i open html files in browser, the images are displayed properly.. So, What is the correct path for images..?? If i set full path to src attribute of <img> tag..it works. but i think its not a proper way. :( EDIT: If i assign d:\myapp\bin\HtmlPages\support.gif then image is displayed. And if i assign "..\HtmlPages\support.gif" or "support.gif" image is not shown.

  • Replacement background image not showing when using GreaseMonkey

    - by Dave C
    I'm trying to use GreaseMonkey to replace the background image of a DIV on bing.com. It's a pretty straightforward call to GM_addstyle: GM_addStyle(".sw_logo " +"{background:url('http://www.kpao.org/blog/kpao-bing-logo-inverse.png') " +"no-repeat 21px 7px transparent}"); However, the image doesn't show up. It's clearly visible in Firebug, and as I twiddle with the CSS in Firebug, I can get it to show up. But it doesn't stay. Any thoughts on why? Maybe it's a bug, but then maybe I'm missing something obvious. Thanks!

  • Background image of table cell

    - by Shuaib
    Hey guys, Trying to set a background image for a table view cell, tried almost everything but failing. Hoping someone would notice what I am doing wrong. Here is how my current code looks like: static NSString *CustomCellIdentifier = @"listCustomCell"; listCustomCell *cell = (listCustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"listCustomCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[listCustomCell class]]) cell = (listCustomCell *)oneObject; } cell.backgroundColor = [UIColor clearColor]; UIImageView *backgroundImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"list_selected.png"]]; //[cell setBackgroundView:backgroundImageView]; cell.backgroundView = backgroundImageView; The image won't show up in the background of the cell. All I see is plain white background. Thanks for help.

  • Sending series of images to display like a movie on iPhone

    - by unknownthreat
    Allow me to elaborate more. On the server, we will have a program that will take data from iPhone and process that data and produce series of images. Each time an image is generated, it will be send back to display on iPhone. I have done all of the things above using UDP, OpenGL, and such. It works. The images are transferred to iPhone and can be displayed, but it is slow. The image's resolution is around 320 x 420 and we send the image pixels by pixels. This naive implementation leads to a slow framerate. I can see around 2-3 frames per second. There are also some UDP packets dropped, and this is expected. Are there any sort of compression method available for something like this? Are there any other method that can make this better? NOTE: please don't just write "compression" as an answer, because we are aware that we will need to do it in some ways.

  • How to display image that is located on another server on the network (ASP.NET)

    - by eviljack
    I've got a ASP.NET site that's located on a local server (MY_SERVER). And one of the things it does is pull up tiff files which are located on another server (ANOTHER_SERVER). The location of each of these files is stored in SQL. I pull up each of these images and am supposed to display them. The problem is: the files are not named with a tiff extension (does it matter?) they aren't displaying at all. I am using an Image control to display these images, and I'm not sure if it matters that the extension is not set (does the image control know the difference between an jpg and a tiff without the extension?) I am guessing the images aren't displaying because they are not on the same server MY_SERVER that the images are located (ANOTHER_SERVER). Any ideas on how to fix this?

  • how to apply Discrete wavelet transform on image

    - by abuasis
    I am implementing an android application that will verify signature images , decided to go with the Discrete wavelet transform method (symmlet-8) the method requires to apply the discrete wavelet transform and separate the image using low-pass and high-pass filter and retrieve the wavelet transform coefficients. the equations show notations that I cant understand thus can't do the math easily , also didn't know how to apply low-pass and high-pass filters to my x and y points. is there any tutorial that shows you how to apply the discrete wavelet transform to my image easily that breaks it out in numbers? thanks alot in advance.

  • MOD Rewrite Mask for Image URL

    - by user345426
    Okay so I am launching a cloned e-commerce site. I want to create a rewrite rule for the image folder for the second site to fetch images from the first site. RewriteRule ^alice.gif$ www.rhinomart.com/images/h_home.gif When I go to alice.gif directly through the browser it simply redirects me to the rhinomart.com URL and image. How do I prevent the redirect from occurring? When I go to http://www.acnbiz.net/alice.gif it should fetch alice.gif directly from Rhinomart.com/images and not redirect. is it possible???

  • CSS Rollovers: how to maintain "hit area" size when hidden image is larger than anchor area

    - by nukefusion
    I have a small problem and I don't think what I want to do can be achieved with just pure CSS, but I figured I'd ask anyway. Basically, I have one DIV which contains a hyperlinked element that is smaller in size to it's parent DIV. So in effect I have a square within a square with the inner square being the "hit area". When I mouse over this inner square I want the background of the outer square to change. I know it's not possible to change the parent DIV's background on a:hover, but I figured I could give the illusion of it happening by nesting a hidden image inside the anchor. This works great until I want to "roll off". The problem is that I want the image to disappear when I leave the area of the anchor tag, not the larger hidden image. Is this possible? For the benefit of everyone I've provided an example to demonstrate what I mean: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Test Rollover</title> <link href="main.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="d1"> <a href="#nogo"> <b id="b1"></b> <b id="b2"></b> </a> </div> </body> And the css: #b1 { width: 200px; height: 200px; top: 100px; left: 100px; background-color:aqua; position: absolute; z-index: 100; } #b2 { width: 400px; height: 400px; background-color:lime; position: absolute; display: none; z-index: 90; } #d1 { width: 400px; height: 400px; background-color:fuchsia; position: relative; } #d1 a:hover #b2 { display: block; } In this example I want the green outer square to disappear when I leave the bounds of the hidden inner blue square.

  • How to draw a transparent stroke (or anyway clear part of an image) on the iPhone

    - by devguy
    I have a small app that allows the user to draw on the screen with the finger. Yes, nothing original, but it's part of something larger :) I have a UIImageView where the user draws, by creating a CGContextRef and the various CG draw functions. I primarily draw strokes/lines with the function CGContextAddLineToPoint Now the problem is this: the user can draw lines of various colors. I want to give him the ability to use a "rubber" tool to delete some part of the image drawn so far, with the finger. I initially did this by using a white color for the stroke (set with the CGContextSetRGBStrokeColor function) but it did't work out...because I discovered later that the UIImage on the UIImageView was actually with transparent background, not white...so I would end up with a transparent image with white lines on it! Is there anyway to set a "transparent" stroke color...or is there any other way to clear the content of the CGContextRef under the user's finger, when he moves it? Thanks
