Corner.js 1.8 allows you to add corners (and also shading and shadow) to images on your webpages (alternatively: glossy.js). It uses unobtrusive javascript to keep your code clean. It works in all the major browsers - Mozilla Firefox 1.5+, Opera 9+, IE 6+ and Safari. On older browsers, it'll degrade and your visitors won't notice a thing.

Setting Up

Download "corner.js" and include it into your webpage.

Using It

To add corners just add a class="corner" and an additonal class like "iradius16" to the image.

Classes

• Initialisation class "corner"
• vary the radius by adding iradius followed by the desired radius in pixel:
  Corner radius class "iradius24" - min=0 max=100 default=0
• vary the shading by adding ishade followed by the desired opacity in percentage:
  Image shading class "ishade50" - min=0 max=100 default=0
• vary the shadow by adding ishadow followed by the desired opacity in percentage:
  Image shadow class "ishadow33" - min=0 max=100 default=0
• vary the shadow by adding inverse:
  Shadow invert class "inverse"

Scripting

If you want flexibility, use "cvi_corner_lib.js" instead of "corner.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_corner.defaultRadius = 0; //INT 0-100 (px)
cvi_corner.defaultShadow = 0; //INT 0-100 (% opacity)
cvi_corner.defaultShade = 0; //INT 0-100 (% opacity)
cvi_corner.defaultInverse = false; //BOOLEAN

Add images using Javascript

cvi_corner.add(image, options);
image should be an image element: document.getElementById("myimg")
options can contain one or more values: {radius: value, shadow: value, shade: value, inverse: value}

Example:

cvi_corner.add(document.getElementById("myimg"), { shadow: 75, shade: 0 });

Modify images using Javascript

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

Example:

cvi_corner.modify(document.getElementById("myimg"), { radius: 50 });

Remove effect from an image using Javascript

cvi_corner.remove(image);

Alternatively use "cvi_corners_lib.js" instead of "justcorners.js".

Set defaults using Javascript

cvi_corners.defaultXradius = 16; //INT 0-100 (px)
cvi_corners.defaultYradius = 0; //INT 0-100 (px)
cvi_corners.defaultCorners = "1111"; //STR "0000"-"1111" [top left|top right|bottom left|bottom right]
cvi_corners.defaultBorder = 0; //INT 0-100 (px borderwidth)
cvi_corners.defaultColor = "#0000ff"; //STR "#000000"-"#ffffff" bordercolor
cvi_corners.defaultOpacity = 100; //INT 0-100 (% borderopacity)


Add images using Javascript

cvi_corners.add(image, options);
image should be an image element: document.getElementById("myimg")
options can contain one or more values: {xradius: value, yradius: value, corners: value}

Example:

cvi_corners.add(document.getElementById("myimg"), { corners: "1010" });

Modify images using Javascript

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

Example:

cvi_corners.modify(document.getElementById("myimg"), { xradius: 20, yradius: 10 });

Remove effect from an image using Javascript

cvi_corners.remove(image);

Demonstration

Shows some of the things "corner.js" does.

class = "corner"

class = "corner ishade50"

class = "corner ishadow20"

class = "corner ishade50 ishadow20"

class = "corner ishadow40 inverse"

class = "corner iradius16"

class =
"corner iradius24 ishadow33 inverse"

class =
"corner iradius20 ishadow33"

class =
"corner iradius8 ishade75 ishadow33"

class =
"corner iradius16 ishade66 ishadow30"

class =
"corner iradius32 ishade50 ishadow25"

class =
"corner iradius48 ishade33"

Scaled and linked

2/3 image width and height

class =
"corner iradius12
ishade50 ishadow20"

1/2 image width & height

class =
"corner iradius10
ishade66 ishadow25"

1/3 width & height

class =
"corner
iradius8
ishade75
ishadow30"

justcorners.js instead of corner.js

• Initialisation class "corners"
• vary the radius by adding iradius followed by the desired radius in pixel:
  Corner radius class "iradius24" - min=0 max=100 default=16
• vary the corners by adding iradiae followed by the desired bits as bitchain:
  Corner selection class "iradiae1010" - default=1111 [top left|top right|bottom left|bottom right]
• vary the border by adding iborder followed by the desired width in pixel:
  Corner border class "iborder2" - min=0 max=100 default=0
• vary the border color by adding icolor followed by the color as string:
  Border color class "icolor0000ff" - min=000000 max=ffffff default=0000ff

class =
"corners iradius32"

class =
"corners iradiae1010"

class =
"corners iborder1 icolorffffff"

Supports "usemap"

Why use Javascript Image Corners?

• Fast and easy to implement. Just add class="corner iradius[n]" to the image and your good to go.
• Don't need to spend time in an image editor creating images with corners.
• Works really well with forum avatars. Doesn't require additional server work.
• It's dead easy to change the attributes of the corners.
• 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.

Restrictions

Opera do not support printing of canvas.

Credits

Original idea is mine but the inspiration for the script came from reflection.js.

History

• Added smooth border shading and shining

• Added border support for cvi_corners_lib.js and justcorners.js

• Added scriptable lib versions cvi_corner_lib.js and cvi_corners_lib.js

• Added soft shadows for Internet Explorer 6/7

• Added support for img attributes:
  id alt title src onclick
• Added Internet Explorer support for iradiae

• Added support for Internet Explorer 6/7
  (iradiae is missing and shading isn't complete)

• Added usemap support for block element surrounded images

• Added soft shadows
• Appended justcorners.js

• Initial Release
