Hi,
I was wondering if it would be possible to programmatically add area annotation to a model in Simulink.
I have used Simulink.Annotation() to add textual annotation which works fine. I'm looking for a way of highlighting a particular section of the model programmatically depending on certain conditions. The size and position of the area would be determined at runtime.
Any pointers would be much appreciated.
Thank you,
sunny

An "Area" is an "Annotation", with empty "Name", "DropShadow" set as "On".

Not sure that's true.
You can move blocks inside an area together, create a subsystem from blocks inside an area, etc. So I don't think an area annotation is same as an empty text annotation.

You are right, although my statement is also true if you run get_param() on an "Area" and an "Annotation". Anyway, I found a way to create an "Area" by command line:
f14;
add_block('built-in/Area','f14/area','position',[500,20,900,400])

Hi Fangjun Jiang,
That is exactly what I was after. I must've overlooked it in the documentation, so I was always using Simulink.Annotation() instead of add_block(). Thank you.

A follow up question to this. Can one take a screenshot of only the area created?
