How to make a blurry background image?

I use the app free umbrella of Eugene Popov.

and I wonder how this app blurs the background image,

It's pretty cool

anyone has any ideas on this subject?

dlib library seems to do quite easily, but have not tried.

Here is the glaussian_blur() function:

And here is an example of code using this function:

  • How can I change the background image for a single tab on the navigation bar

    I create a film site for LEVEL and for the navigation bar, I intend to have a different character for each tab. However, I can't put one image of each separate tab. Instead, a single image appears on each of the tabs. Here is an example of the CSS source.

    < td width = "200" > < ul id = "navigation" > < br / >

    "< li > < a href ="... / pages/index.html "> home < /a > < /li > < br / >"

    "< li > < a href ="... / pages/cast.html "> Cast < /a > < /li > < br / >"

    "< li > < a href ="... / pages/pictures.html "> photos < /a > < /li > < br / >"

    "< li > < a href ="... / pages/soundtrack.html "> music < /a > < /li > < br / >"

    "< li > < a href ="... / pages/interview.html "> Interviews < /a > < /li > < br / >"

    "< li > < a href ="... / pages/links.html "> links < /a > < /li > < br / >"

    < /ul >

    < table >

    #navigation {}

    list-style-type: none;

    padding: 0px;

    margin: 0px;

    }

    #navigation li {}

    margin: 0px;

    padding: 0px;

    list-style-type: no

    }

    #navigation li a: link, #navigation li a: visited {}

    display: block;

    Width: 200px;

    height: 100px;

    text-decoration: none;

    text-align: center;

    line-height: 100px;

    do-family: "Trebuchet MS", Arial, Helvetica, sans-serif;

    make-weight: bold;

    -ms-transition: 1000ms relieve;

    -o - transition: 1000ms relieve;

    transition: 1000ms relieve;

    color: #648AAE;

    background-repeat: no-repeat;

    background-image: url (.. / Images/gifs/Batman-still-2.gif);

    background-position: center bottom;

    text-transform: uppercase;

    letter-spacing: 0.79em;

    border-radius: 5px;

    }

    #navigation li a: focus, #navigation li a: hover, #navigation li a: active {}

    background-repeat: no-repeat;

    background-position: center bottom;

    background-color: #454545;

    border-radius: 25px;

    }

    So, how can I put one image on each of the tabs (home, cast, photos, etc.). Thanks in advance for your help.

    Assign a class to the element, and use CSS to apply an image as in

  • class = 'home'; > Home

  • Cast

  • Photos

  • Music

  • Interviews

  • Links

  • and the CSS

    #navigation li a: link. Home, #navigation li a: visited. Home {}

    background-image: url (.. / Images/gifs/Batman-still-2.gif);

    }

  • How can I get a background image sensitive identical to the junction College Web site?

    Hello!

    I tried hard to figure out how to get the same effect that has College Junction - home - daily well-being all together . More specifically, the ability to resize the window of my browser and have scale of the background image to size without image quality loss. I have a 1920 x 1034 image. The width of my page is fixed to 800px. Then I fill an object with my image (suitable size) and apply the function of width of 100%. When I saw these settings in the browser, I'm able to resize the upper window of the page of 800px with desirable effect of the image scaled to fit the browser BUT the image loses quality (resolution).

    I bought the QooQee Widget: Smart 1.1 and I'm able to do a little bit reactive recess with her, but I have not found a way to create the same effect as the junctions of college. The best I can do is create an effect similar but end with gray side bars when I resize the browser to one size other than the proportions of the image. (see below)

    site iamge.PNG

    It was a little maddening for me. I have to do something wrong. Maybe my page properties were not correctly setup? Any help would be appreciated, thanks!

    More specifically, the ability to resize the window of my browser and have scale of the background image to size without image quality loss.

    There is no such thing, and there may be - for simple mathematical reasons. The web site that you referenced uses magical, just a very large image (oversized) that most of the browsers is not displayed to the maximum size one way or another. It's an illusion at low cost. The only other factor is the pixel, scaling the browser and in the case of Chrome algorithms, they are dependent on the GPU acceleration, so it's more likely something is wrong with that, if you really see the degradation.

  • How to make a transparent background when editing

    Hello

    I was wondering how to get a transparent background in flash.  I did a lot of research and have seen many forums, but I don't want my file to export to HTML.  Is it possible to have a transparent background, with some having to have a HTML file?  I try this enter into Camtasia Studio, but there is a white rectangle behind the animation, blocking all the rest.

    Thank you

    Orion31

    You export a video to enter in Camtasia? If, therefore, in the export options video there is a checkbox to say to ignore the color of the scene and to generate an alpha channel. Don't say to compress the video in Adobe Media Encoder, just take the MOV file in Camtasia.

    If you say that Camtasia supports importing of SWF files, then it would be Camtasia to make the background transparent.
