Synchronize the writing of several products from Python API.
It would be nice to have a way of using multiwriter from Python API without having to define a new application like AppImageListWriter in MAJA.
If we consider a flow like the following:
+----+ /--------\ +-----+ /----------------\ +---------+ /------------\ +----------+ /----------\ +-------+
| S1 | --> | to_xyz | --> | XYZ | --> | extractNormals | --> | Normals | --> | computeLIA | --> | LIA | --> | OrthoLIA | --> | S2LIA |
+----+ \--------/ +-----+ \----------------/ +---------+ \------------/ +----------+ \----------/ +-------+
|
|
v
+------------+ /----------\ +----------+
| Sin | --> | OrthoSin | --> | S2Sin |
+------------+ \----------/ +----------+We don't have any way (as of v7.2) to plug extra applications on separate paths after an application that produces several images.
In an ideal world, we could write something like
otb.write_outputs(appOrthoLIA, appOrthoSin)
