JAI Image Manipulation Task Example

[Kevin Grey <KG...@dynamicsoft.com>]

Heya,

	Please comment on the following image manipulation task.  The
operations would be performed depth-first and would pass the resulting image
up the branch to the next element.  This example draws aligned text inside a
rectangle with a transparent background, which is then drawn to the
coordinates (50,50).  The image is then scaled to 10% of its size, rotated
45 degrees, then draws what ends up to be a circle with a diameter of 1
pixel.  It then does some levels adjustments.  I haven't considered stuff
like color balance or composites too much.  Let me know what you think.

<image-manip srcdir="D:/development/jakarta-ant/TEST_IMAGES"
includes="**/*.jpg,**/*.bmp">
	<draw xloc="50" yloc="50">
		<rectangle width="10" height="10" bgcolor="transparent">
			<text align="left" valign="middle" point="10"
string="Hello World"/>
		</rectangle>
	</draw>
	<scale dim="10%x10%"/>
	<rotate angle="45"/>
	<draw xloc="40" yloc="40">
		<scale dim="1x1">
			<circle bgcolor="FF0000" radius="5"/>
		</scale>
	</draw>
	<levels brightness="50" contrast="50" gamma="1.4"/>
	<autolevels/>
</image-manip>

shrinking down large images to thumbnails, generating an XML list of said
large images and thumbnails then XSLT-ing it into a file.

Batik has an ant task, so they must have found other uses

Please provide a use case for an Image Manipulation
task in a build environment.
