Filters give a great variety of visual effects in web pages dynamically. Image Filters are of three types:
- Gray:-The Gray Filter applies a grayscale image effect in which all color is stripped from the image and all that remains in brightness data.
- Xray:-The Xray Filter applies an Xray effect which is just an inversion of the Gray effect.
- Invert:-The Invert Filter applies a Negative Image effect ie: dark areas become light and light areas become dark.
File name must be given with STYLE attribute as follows:
STYLE="filter:gray"
For example, look at following code snippets:
<Html>
<Body>
<br>
<br>
<table>
<tr>
<td>
<img src="F:\photo.gif" >
</td>
<td>
<img src="F:\photo.gif" STYLE="filter:gray">
</td>
<td>
<img src="F:\photo.gif" STYLE="filter:xray">
</td>
<td>
<img src="F:\photo.gif" STYLE="filter:invert">
</td>
</tr>
<tr align="center"><td>Normal</td>
<td>Gray</td>
<td>XRay</td>
<td>Invert</td>
</tr>
</table>
</Body>
</Html>
