Please use the users list for questions about how to use GeoTools.
What you want to do is probably possible. The tricky bits are what projection your tiff is in and that the zipcode (centroids?) are also in a projected coordinate system.

We are first time users of GeoTools. Our use case is for a given tif image & radius, we would like to know if there is possibility in geotools API to get all pixels falling within the radius (with zipcode ,distancewhich can be 10km,20km or miles from zipcode as input) . The output should be pixel values from input geo location to 10kms radius.
