Split Image - CodeProject®

Sample screenshot

Introduction

You can create some nice pictures by splitting them up into smaller images. Doing this in Photoshop and keeping the proportions isn't easy (I'm no photoshop guru), instead you can do it using a table. The code below creates the image of the sailboat.

How it's done

The image is loaded into a table as a background image

<style>
#splitimg {
    background:url(http://soderlind.no/s/splitimg/sailboat.gif);
    width:  300px;
    height: 400px;
}
</style>
.
.
.
<table id="splitimg">

Or, if you don't like to use CSS:

<table background="http://soderlind.no/s/splitimg/sailboat.gif" <BR>    width="300" height="400">

Next, place a grid on top of the image using table rows and colums.

<tr>
    <td class="transp"> </td>
</tr>
<tr>
    <td class="hide"></td>
</tr>
<tr>
    <td class="transp"> </td>
</tr>
<tr>
    <td class="hide"></td>
</tr>
<tr>
    <td class="transp"> </td>
</tr>

A TD with a background color will hide that part of the image:

.hide {
    background-color:  #FFFFFF;
    width:  10px;
    height: 10px;
}

A TD without background color will be transparent:

.transp {
    border: 2px solid #000000;
    width:  300px;
    height: 113px;
}

Complete sample code:

<!-- Insert the STYLE code into the <HEAD> section of your page -->

<style>
#splitimg {
    background:url(http://soderlind.no/s/splitimg/sailboat.gif);
    width:  300px;
    height: 400px;
}

.hide {
    background-color:  #FFFFFF;
    width:  10px;
    height: 10px;
}

.transp {
    border: 2px solid #000000;
    width:  300px;
    height: 113px;
}

</style>

<!-- Insert the TABLE code into the <BODY> section of your page -->

<table id="splitimg" cellspacing="0" cellpadding="0" border="0">
<tr>
	<td class="transp"> </td>
</tr>
<tr>
	<td class="hide"></td>
</tr>
<tr>
	<td class="transp"> </td>
</tr>
<tr>
	<td class="hide"></td>
</tr>
<tr>
	<td class="transp"> </td>
</tr>
</table>

Doing this by hand isn't easy, so I created a tool you can use - http://soderlind.no/s/splitimg/default.asp
