Filter watchers not working with writers

Mantis Issue 15, reported by jinglada, assigned to jmichel, created: 2008-10-28

The progress is not reported. It is only shown at the end of the processing. It works with filters.

With non streamed writers there is no information at the beginning of the processing and one gets:

ImageFileWriter "Writing"

Filter took 0.300398 seconds.

at the end. Note the absence of [***].

With streamed writers the output is:

  1. at the beginning of the processing: "StreamingImageFileWriter "Writing"
  2. At the end: Processing progress:100% [**************************************************] Filter took 98.7035 seconds.

With the watcher on a filter the behaviours is OK.

This was tested with a StandardFilterWatcher, but the behaviour is the same for the FltkFilterWatcher.

All application suffer from this. Only the watchers plugged on filters work: quick-look generation for the viewer, for instance.
