How to select data from figure with predefned window?

Is it possible to select data from figures with different kinds of predefined windows? e.g. select 10 samples and 20 samples windowlength from a figure and save corresponding the data. I looked into the brush function, but I don't know how to predefine the windows. It is also necessarry to see the selecting window during selecting, because I want to avoid artefacts in the selected part.

If you don't have the data that defined the image then you can get it from the image handle as this property. Then you can index into it with any window you like.
