Description of the provided commands


This extension provides two new commands, transform and unstack.

Subcmd Description
channel -command command

This command creates a new generic transformation channel and stacks it above the specified base <channel>. The given <command> is executed whenever something of importance happens on the channel, it has to implement the desired behaviour of the transformation.

For now see doc/manual for a complete description.


This command provides a tcl-level interface to Tcl_UnstackChannel. If no transformation was stacked upon <channel> this is equivalent to close channel. Else it removes the topmost transformation from the stack.
