- Recycle captured bitmap in createBitmapFromActivity() after saving to disk, eliminating ~9.6 MB leaked per test invocation - Switch IntBuffer allocation from heap (IntBuffer.allocate) to native memory (ByteBuffer.allocateDirect) to bypass JVM heap constraints - Add overflow guard for large capacity * INTEGER_BYTES computations - Wrap ParallelPixelProcessor analyze() and transform() in try/finally to guarantee buffer cleanup on exceptions - Recycle diff bitmap in HighContrastDiff.generate() after saving - Update ImageBufferTest to reflect direct buffer allocation behavior
Replace full-image IntBuffer allocation with stripe-based processing to dramatically reduce peak Java heap usage during bitmap comparison. - Process bitmaps in horizontal stripes using Bitmap.createBitmap() sub-regions and copyPixelsToBuffer(), keeping per-stripe heap usage under ~1 MB instead of ~19 MB for full-image buffers - Stripe height is dynamically calculated based on available heap memory - Revert ByteBuffer.allocateDirect() change (no benefit on Android where direct buffers use VMRuntime.newNonMovableArray on the Java heap) - Add mockBitmapCreateBitmap() test helper and update all processor tests
