how can I find out if the user has choosen RenderRegion/Render Active Objects. I tried it with RDATA_ACTIVEOBJECTSONLY but that isn't working and I don't find the command for Render Region and the choosen coordinates for Render Region.

this can be found by checking for a few things
firstly check if the editor render flag is set
if it is you can ask for the resolution of the render ray->sizex,ect
the ask check as follows
x1 = ray->left;
y1 = ray->top;
x2 = ray->right;
y2 = ray->bottom;
if this w and h are not the same as the xres or yres then you know that this is a marque render.
there are no commands for render region.
you must make a render thread , create/ clone a document and call renderdocument.
for this you must provide a bitmap among other things.
its important that the bitmap be the same size as the xres,yres even if your just doing a marque render.
I hope that helps

thanks that will help and how can I find out RenderActiveObject for the editor renderer?

what do you mean by RenderActiveObject ?
I dont understand that bit cam you explain a bit more and I can maybe help you.

I mean when you make editor rendering you have 3 different choices Render All in the Editor / Rende Region or Render Active Objects. That means it render only the selected objects into the edior. I have tried RDATA_ACTIVEOBJECTSONLY but that only return the setting for Render Active Objects in the Global Render Settings and not for the edior rendering.

I haven't found any way to access this information and are still waiting for a reply from the programmers. I guess you could see if all objects in the scene are active. (If they still are in the render document.)
Out of curiosity, why do need this flag?

Uhh... Maybe I am missing the point here, but, doesn't GetActiveDocument()->GetActiveObjects() do the trick? Get AtomArray and loop through objects, done. Anyway, that is what I did for VELMA.
Mikael, I think the reason she wants the active objects is to only generate the NPR strokes for those objects. Otherwise the NPR strokes would be generate for all objects in the scene even though only the active objects were rendering. Might have something to do with speed also. ( this is assuming Cathleen is generating the strokes from the scene and not the render geometry ).
My unbounded speculations...

I guess she means the detection of the call itself. She wants to detect if this command is chosen by the user rather than getting the active objects themselves.
If not, yes, looping thru the AtomArray is the way to go as darf mentions.

Huh, that makes sense too. I will have to go look at the VELMA code as I believe I solved that. Hmm...

According to the programmers, the flag isn't set in the main document, but in the render data. The render data is available to all post effects and can be retreived using Render::GetRenderData().
