 There are two reasons why QuPath uses `RegionRequest` objects:
 
-- You'd otherwise need to pass a lot of parameters to the `readBufferedImage` method
+- You'd otherwise need to pass a lot of parameters to the `readRegion` method
 - `RegionRequests` can be (and are) used as keys for an image cache
 
 In any case, the above script assumes a single-plane image.
