How can I get the dimensions of the composition?

I am creating a plug-in that expands the size of the output buffer.

Currently, the user must manually set the input layer, such as the output corresponds to the model after the expansion of the buffer.

I want to do is make an option that creates and the size of the composition of output such as a not updated entry on the scale fits directly into the model.

I intend to do this in a last step using PF_COPY.

My problem is that I can't get the size of the publication.

How do I do that?

I'm on 2015 SDK and I want my plugin to work in AE and first CC

the following steps will have the size of the model:

1 AEGP_GetEffectLayer()

2 AEGP_GetLayerParentComp()

3 AEGP_GetItemFromComp()

4 AEGP_GetItemDimensions()

However, it would be the size of the model in full resolution. Be aware that if you

you will need to take into account the factors of downsample.
