Dmip: remove node ? unlink ?

Oliver — Wed, 27 May 2009 09:29:58 GMT

Hello,
I didn't find a way to remove a node froma graph, and to unlink two nodes.
Is it a planned feature, is it by design ?
Today I must rebuild the whole graph each time I want to make a small change (ie bypass a node).

Alternate question: is there a way to disable a node (ie inPlace processing will do nothing, and regular processing will copy the first source image input) ?

Regards
Oliver

Hi Oliver,

Why do you need unlink capability? Are you trying to implement dynamically (at run time)modified graph? Note, you will need to compile a graph after changes in its configuration.

There is no such capability in DMIP predefined nodes. I think you may implement this in your custom node.

Vladimir

Do you mean to disable SrcNode from processing?

If yes, DMIP can sometimes to remove it. It behaviour depends (do copy or do nothing) on several factors:

1. image data pointer and step: if they are not aligned - DMIP creates small aligned buffer and copy-in data.

2. Source data consumers: filters after SrcNode need border values, If you don't prepare border yourself, DMIP will do it for you.
