Summary

This RFC is mostly a fix for a missing RAM parameter to be used by any persistent filter in OTB applications.

Rationale

The RAM parameter is not used automatically when calling a persistent filter in an OTB application. It is necessary to set it in the DoExecute() : filter->GetStreamer()->SetAutomaticAdaptativeStreaming(RAM);

The RAM parameter has been added in applications that needed it. Its value has been forwarded to all persistent filters. A few exceptions although :

Application Segmentation : the tile size is a parameter of the application
Applications using otb::StreamingShrinkImageFilter : this filter doesn't allow us to set RAM usage.

Tests

Documentation

Additional notes

This RFC could be extended with some work on the StreamingShrinkImageFilter to make it support a custom RAM usage.
