Example Usage

DPML

<instr>
  <type>imageNoise</type>
  <operand>var:myimage</operand>

NetKernel Foundation API

req=context.createSubRequest("active:imageNoise");
req.addArgument("operand", [resource representation, aspect, or URI] );
req.addArgument("operator", [resource representation, aspect, or URI] );
result=context.issueSubRequest(req);

Purpose

Adds dithered noise to an image with the level specified by the operator.

The operator document specifies the noise level (ranging from 0-255). Its syntax is

<imageNoise>
  <level>100</level>
</imageNoise>

imageNoise accepts and returns an ImageAspect resource which holds a Java AWT bitmap image and can be pipelined into any other image tool.
