NetKernel Foundation API

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

Purpose

Scales an image to the dimensions specified by the operator.

The operator document specifies the scale dimensions in pixels. Its syntax is

<imageScale>
  <width>50</width>
  <height>50</height>
</imageScale>

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