Clear Lens - JQuery Plugin


This is my New jQuery Plugin.  You can find the working example at http://jsfiddle.net/ajai/k8Ube/
Hope it will be useful to some one.... 

I have used "pixastic" for image processing. 

To implement the plugin you have to include the pixastic library. and call the plugin in $(window).load event, Beacuse for image processing first the image should be loaded. Hope you all know $(window).load will be triggered after all the assets are loaded.

DEMO

Fork this on GitHub

How to use?

It is very simple to implement the plugin
1. include you jQuery 
2. include Pixastic Library
3. include the plugin code
4. Add attribute fitler="blur" for images that you want to apply
5. on $(window).load Event call the following code

$('img').blurLens();
or 
$('img').blurLens({
    width: 200,
    height: 200,
    blur: 5
});
width - Width of lens
height - Height of lens
blur - Blur Amount

JQuery 

(function ($) {
    $.fn.blurLens = function (lensproperty) {

        return $(this).each(function (ind, elm) {
            if ($(elm).attr('filter') == 'blur') {
                var w = 50;
                var h = 50;
                var blur = 2;

                if (lensproperty && lensproperty.width) w = lensproperty.width;
                if (lensproperty && lensproperty.height) h = lensproperty.height;
                if (lensproperty && lensproperty.blur) blur = lensproperty.blur;

                $(elm).wrap('

');

                var wrapper = $('



').width($(elm).width()).height($(elm).height());
                wrapper.appendTo($(elm).parent());


                var lens = $('



').css('background', 'url(' + $(elm).attr('src') + ') no-repeat 0 0').width(w).height(h);
                lens.appendTo(wrapper);

                var endL = $(wrapper).width() - w;
                var endT = $(wrapper).height() - h - 3;

                $(wrapper).on('mousemove', function (e) {
                    lens.show();
                    var l = e.pageX - $(this).offset().left;
                    var t = e.pageY - $(this).offset().top;
                    lens.css({
                        left: l + 'px',
                        top: t + 'px',
                            'background-position': '-' + l + 'px -' + t + 'px'
                    });
                });

                $(wrapper).on('mouseout', function (e) {
                    lens.hide();
                });

                $(elm).parent().css('visibility', 'visible');

                $(elm).pixastic("blurfast", {
                    amount: blur
                });
            }
        });
    }
})(jQuery);

CSS

.blur {
    visibility: hidden;
    position:relative;
}
.blur .lens-wrap {
    position:absolute;
    top:0;
    left:0;
    width:100%;
    height:100%;
    z-index:200;
    overflow:hidden;
}
.blur .lens {
    display:none;
    width:50px;
    height: 50px;
    border:1px solid rgba(0, 0, 0, 0.5);
    box-shadow:0px 0px 10px #333;
    position:absolute;
    top:0;
    left:0;
    /*border-radius:100%;*/
    z-index:100;
    box-sizing:border-box;
    -moz-box-sizing:border-box;

Random Bouncing Ball Animation

Simple Animation Using C

Here i have used fillpoly function to draw the object body and used fillellipse function to draw tier. animation is done by looping through the objects x & y position until user hits a key. Keypress event is achived  by using kbhit function. Smoothness of animation is controlled by delay function. Change the delay values to change the animation speed Source: #include<stdio.h> #include<conio.h> #include<graphics.h> #include<dos.h> void main() { int gd=DETECT,gm,i=-300,j; int poly[16]={100,100,250,100,250,50,300,50,325,90,325,140,100,140,100,100}; int tpoly[16]={100,100,250,100,250,50,300,50,325,90,325,140,100,140,100,100}; initgraph(&gd,&gm,""); getch(); while(!kbhit()) { for(j=0;j<16;j+=2) { poly[j]=tpoly[j]+i; } fillpoly(8,poly); setfillstyle(5,7); bar(275+i,60,295+i,85); setfillstyle(5,8); fillellipse(140+i,140,20,20); fillellipse(280+i,140,20,20); setfillstyle(1,0); fillellipse(140+i,140,10,10); fillellipse(280+i,140,10...

RGB in C

Default palette size for normal graphics driver is 16 i.e) the color number rages from 0 to 15 To use rgb color modes we have to choose VGA or IBM 8514 as a graphics driver For VGA, Palette size is 16 i.e) color number ranges from 0-16 For IBM 8514, Palette size is 256 i.e) color number ranges from 0-255, we can also say it as VGA with 256 palette size By using setrgbpalette function we can generate RGB colors, we can generate colors with respect to Palette size. This function replaces the default palette colors with the generated Palette colors. Syntax: void setrgbpalette(int colornum, int red, int green, int blue); /* colornum - color number in palette (0-15 or 0-255 depens on graphics driver) red - color value for red (0-255) green - color value for green (0-255) blue - color value for blue (0-255) */ Example: #include<graphics.h> #include<stdio.h> #include<conio.h> #include<stdlib.h> #include<time.h> void main(){ in...
