The PR name follows the format `[SEDONA-XXX] my subject`. ## What changes were proposed in this PR? We've spotted several performance hits of map algebra functions: 1. `ImageUtils.createConstantImage` is very slow, we'd better manually create a buffered image, which is way faster. 2. The `.getData()` method on `BufferedImage` objects creates an unnecessary copy of the raster object. We've added a utility function to implement a fast path for `BufferedImage`. ## How was this patch tested? Passing existing tests ## Did this PR include necessary documentation updates? - No, this PR does not affect any public API so no need to change the docs. -- This is an automated message from the Apache Git Service.
