jQuery ImgBox Plugin

jQuery plugin that draws a box over an image.

Overview

ImgBox reads data- attributes to your image tags and draws a custom styled box over the image. See the demo page for examples.

ImgBox also has an drawable edit mode and you can update the position of the box yourself at anytime.

This plugin can be used with minimum changes to your existing code.

1. jQuery

Size

Usage

Read-only

Place the extra data items into your image tags. You may use width/height or a second set of coordinates. The following 2 are equivalent.

<img data-x="10" data-y="10" data-w="10" data-h="10" class=".." src=".." />

<img data-x="10" data-y="10" data-x2="20" data-y2="20" class=".." src=".." />

You must include one of the mark styler settings when you create the ImgBox, otherwise you won't see anything! Activate the plugin during start up with either of these two minimum configurations. You may specify markClass or markStyle or both but not niether.

$(document).ready(function() {
	$('img').imgbox({markClass:'myclass'});
});

$(document).ready(function() {
	$('img').imgbox({markStyle:{border:'5px solid red'});
});

Editable

The ImgBox has a simple edit mode. Click to set the start point, move the mouse to a new position and click again to trigger the callback function. The data object contains the saved x, y, w, h, x2, y2.

function(data) {}

To switch on edit mode, specify the command as edit and add the saveBox callback.

$(document).ready(function() {
	var imgAdmin = $('img').imgbox({
	markStyle : {
		'border' : '5px solid blue'
	},
	command : 'edit',
	saveBox : function(data) {
		console.log('Thanks for using ImgBox!');
	}
});

If you want to change the coordinates then you need access to the callback object.

$(document).ready(function() {
	var newData = {x: 10, y:10, w:10, h:10};
	var imgAdmin = $('img').imgbox();
	$(img).data(newData);
	imgAdmin.redraw();
});

If you thing imgAdmin needs any other features then create an issue for discussion.
