filter chaining in editor tool

[Matthias Welwarsky-2]

Hello,

how can I chain two filters in an editor tool? I want to use a Levels and an
Invert filter in sequence, the Invert filter working on the output of the
Levels filter. But the setFilter method only allows for setting a single
filter.

regards,
matthias

Hi Mathias.

This is why Batch Queue Manager exist. You cann do it as well into editor.

But for the moment, level tool is not yet ported to BQM. It still
todo. If you is interrested to code it (:=)))...

Actually, I'd rather try to do it like in RawProcessingFilter, implementing a
simple helper filter that calls LevelsFilter and then InvertFilter. But
LevelsFilter doesn't implement chaining and InvertFilter doesn't seem to work
as a slave.

This si why;, porting level tool to BQM is better. Invertfilter
already exist in BQM.

Level tool must be ported as Curve tool.
