Please note: Fragmentors will not be supported in the up-coming NetKernel 4.0 product. We no longer recommend that fragmentors be written nor used. We have converted the image fragmentors to accessors and suggest that any use of this functionality be converted to the accessor form.

---

The image fragmentor is declared in module urn:org:ten60:util:image. It performs basic bitmap image processing by specifying URI fragment declarations. In all cases fragmentation operations are on an image resource specified by a [uri] and with a mimetype which matches image/*.

The image resource could be static or dynamically generated (for example using SVG2Image). Image resource may be of any type supported by underlying Java AWT technologies (PNG, JPEG, GIF, TIFF) - see image parser and image serializer for information in tranrepting image resources.

Quantize

[uri]#quantize(2-256)

Quantize the colour palette of the image down to the specified number of colours - can dramatically reduce image size. Note: quantize looses any transparency in the image.

Crop

[uri]#crop(x, y, width, height)

Crops the image using the x,y top-left co-ordinate and specified width and height.

Scale

[uri]#scale(width, height)

Scales the image to the specified width and height.

Noise

[uri]#noise(0-128)

Adds monochromatic noise to the image.

Background

[uri]#background(red, green, blue)

Sets the background colour to use for transparency - useful for IE browsers which don't render PNG correctly! Each color is an integer from 0-255.
