Shows some of the things reflex.js does.

First 3 images with class "reflex" only, last 3 with "idistance?? iheight?? iopacity?? iborder? icolor??????" ...

"reflex iopacity50"

"reflex iopacity75"

"reflex iopacity25"

Images used are copyrighted and are used for demonstration only.

Download reflex.js and include it into your webpage.

<script type="text/javascript" src="reflex.js"></script>

To get the effect just add a class="reflex" to the image (minimum dimension: 32x32).
The needed vertical space of the canvas element will grow by the height of the reflection, plus the height of the distance.

• Initialisation class "reflex"
• vary the reflection by adding idistance followed by the desired height in pixel:
  Reflection distance class "idistance" - min=0 max=100 default=0
• vary the reflection by adding iheight followed by the desired height in percent:
  Reflection height class "iheight" - min=10 max=100 default=33
• vary the reflection by adding iopacity followed by the desired opacity in percent:
  Reflection opacity class "iopacity" - min=0 max=100 default=33
• vary the border by adding iborder followed by the desired wide in pixel:
  Border wide class "iborder" - min=0 max=100 default=0
• vary the border by adding icolor followed by the desired color as hex:
  Border color class "icolor" - min=000000 max=ffffff default=f0f4ff
• vary the 3D Z-Tilt direction by adding one of the following:
  Z-Tilt direction class "itiltright" or "itiltnone" or "itiltleft"
  by default "reflex.js" cycles through [right|none|left].

If you want flexibility, use "cvi_reflex_lib.js" instead of "reflex.js". You can make your images respond to user actions (e.g. changing one or more options when the image is hovered over).

Set defaults using Javascript

cvi_reflex.defaultTilt = 'none'; //STR 'n|l|r'-'none|left|right'
cvi_reflex.defaultHeight = 33; //INT 10-100 (%)
cvi_reflex.defaultDistance = 0; //INT 0-100 (px)
cvi_reflex.defaultTransparency = 50; //INT 1-100 (%)
cvi_reflex.defaultBorder = 0; //INT 0-20 (px)
cvi_reflex.defaultColor = '#ffffff'; //STR '#000000'-'#ffffff'
cvi_reflex.defaultBoxmode = false; //BOOLEAN
If cvi_filter_lib.js is loaded also...
cvi_reflex.defaultFilter = null; //OBJ [{f='grayscale'},{f='emboss', s:1}...]

Add images using Javascript

cvi_reflex.add(image, options);
image should be an image element: document.getElementById("myimg")
options can contain one or more values: {tilt: value, height: value, distance: value, transparency: value, border: value, color: value, boxmode: value, filter: value}

Examples:

cvi_reflex.add(document.getElementById("myimg"), { height: 25, distance: 10 });
<img onLoad="cvi_reflex.add(this, { height: 25, distance: 10 });" ...>

Modify images using Javascript

cvi_reflex.modify(image, options);
If the image has already an effect but a option value has changed, the effect will be changed accordingly.

Example:

cvi_reflex.modify(document.getElementById("myimg"), { tilt: "left" });

Remove effect from an image using Javascript

cvi_reflex.remove(image);

If you are using the more flexible "cvi_reflex_lib.js" instead of "reflex.js", you'll get access to additional features by the following support libraries (part of distribution):

• cvi_filter_lib.js supports image filtering capabilities. [WYSIWYG-Editor]
  Provides image filter capability for Canvas (only if getImageData/setImageData is supported).
  
  filter : [{#1 filter options},{#2 filter options}...];
  options   e.g. {f: 'contrast', s: 1.5 }
  f == STRING filter name e.g. "invert" Default: null (required)

       "invert" Reverses all colors of the image

       "adjusthsba" Adjust hue & saturation & brightness & alpha channel of the image (s == [h,s,b,a])
       "smooth" Smoothes the image (result is similar to bluring)
       "spinblur" Blurs by rotating the centered image
       "zoomblur" Blurs by zooming the centered image
       "motionblur" Blurs by moving the image to a defined direction
       "outline" Creates grayscaled outline images by different operators (e.g. sobel, prewitt...).
       "blur" Bluring the image by (in build and extendable cvi_matrix object) convolution
       "median" Smoothes grainy images by (in build and extendable cvi_matrix object) convolution
       "sharpen" Makes image sharper by (in build and extendable cvi_matrix object) convolution

       "convolve" Use your own 3x3 matrix via option m=[[n,n,n],[n,n,n],[n,n,n]]

  s == FLOAT/OBJECT multiplier(s) e.g. 0-255 Defaults to... (optional)

       1         if f=="zoomblur|spinblur" Distance (px)
       1         if f=="smooth" Radius (px 1-10)

       [1,0]     if f=="motionblur" Distance (px) and angle (0-360)
       [auto,0]  if f=="convolve" or m!=null. Divisor of convolution result (-1==auto), 
                 useable for normalization and bias (0-255) for brightness addition
       [1,0,     if f=="outline" Divisor of convolution result, bias (0-255)

        [0,0,0]] 

  m == OBJECT kernel matrix e.g. [[n,n,n],[n,n,n],[n,n,n]] Default: null (optional)
  

  
  

• cvi_istack_lib.js supports image stack capabilities. [Example-Demo]
  Provides fading image stacks for Images and CVI Effects.

  Set defaults

  cvi_istack.defaultImagearray = null; //OBJ e.g. [{source:'image.jpg'}]
cvi_istack.defaultMainwidth  = 128; //INT 80-n (px width)
cvi_istack.defaultMainheight = 128; //INT 80-n (px height)
cvi_istack.defaultPlayframes = 20; //INT 1-100 equals frames to fade (* 30 milliseconds)
cvi_istack.defaultPlaydelay  = 5000; //INT 1000-n equals milliseconds (1/1000)
cvi_istack.defaultLoadtimeout= 3000; //INT 1000-n equals milliseconds (1/1000)
cvi_istack.defaultNoiefade   = false;//BOOLEAN IE's Alpha filter produces rough edges
cvi_istack.defaultPlayscript = ''; //STRING e.g. 'cvi_bevel'|'cvi_corner'|'cvi_curl'|'cvi_edge'|'cvi_glossy'|
'cvi_instant'|'cvi_reflex'|'cvi_slide'|'cvi_sphere'|'cvi_strip'
  

  imagearray supports source (required) and options (optional).

  Add stack

  cvi_istack.add(element, options);
  

  element  == div element

  options  e.g. {mainwidth: 128, mainheight: 128, ...}

  imagearray == OBJ Default: null
mainwidth  == INT 32 - n Default: 128
mainheight == INT 32 - n Default: 128
playframes == INT 1 - 100 Default: 20
playdelay  == INT 1000 - n Default: 5000
loadtimeout== INT 1000 - n Default: 3000
noiefade   == BOL true or false Default: false
playscript == STR Default: ''
  

  Advices: All images should have the same aspect ratio like the stack object.
  cvi_slide and cvi_strip creates generally 1:1 objects (using the larger dimension),
  cvi_sphere creates generally 1:1 objects (using the smaller dimension) and
  cvi_reflex creates objects with additional height (for the reflection).
  Hint: By adding a stack to a div element, the former content of the element will be overwritten.

  Get some informations

  FLOAT  = cvi_istack.version;
STRING = cvi_istack.released;

  Play stack

  cvi_istack.play(element);

  Pause stack

  cvi_istack.pause(element);

  Remove stack

  cvi_istack.remove(element);

  Example

  <script type="text/javascript">
  <!--
  	var photos = new Array();
  	photos = [
  		{source:'images/fire.jpg', options:'{tilt:"l",text:"fire"}' },
  		{source:'images/jeans.jpg', options:'{tilt:"r",text:"jeans"}' },
  		{source:'images/rose.jpg', options:'{tilt:"l",text:"rose"}' },
  		{source:'images/swirl.jpg', options:'{tilt:"r",text:"swirl"}' },
  		{source:'images/fruits.jpg', options:'{tilt:"l",text:"fruits"}' },
  		{source:'images/heart.jpg' }
  	];
  	
  	function init_ImageStack() {
  		cvi_instant.defaultPreserve=true;
  		cvi_instant.defaultTilt='left';
  		cvi_instant.defaultFontattr= [100,100,100];
  		cvi_istack.add(document.getElementById('wrapper_div'),{
  			imagearray: photos,
  			mainwidth: 200,
  			mainheight: 200,
  			playdelay: 3000,
  			playscript: 'cvi_instant',
  			noiefade: true
  		});
  	}
  	
  	if(window.attachEvent) {
  		window.attachEvent("onload", init_ImageStack);
  	}else {
  		window.addEventListener("load", init_ImageStack, false);
  	}
  -->
  </script>
    		

• Fast and easy to implement. Just add class="reflex" to the image and your good to go.
• Don't need to spend time in an image editor creating an Cover Flow^™ image effect.
  *Cover Flow is a trademark of Apple Inc..
• Works really well with forum avatars. Doesn't require additional server work.
• It's dead easy to change the attributes of the images.
• Free of charge use on non-commercial and private web sites.

In older browsers, the script degrades and your visitors won't notice a thing.
