  • Makes significant correctness improvements to the FastScaling engine. You may need to adjust your interpolation settings to increase perceptual sharpness.
  • Fixes memory leak in OpenCV (Faces, RedEye) by upgrading OpenCVSharp
  • Performance improvements
  • Adds performance monitoring (see /resizer.debug)
  • Adds support for remote license files and remote reporting of performance and environment/config metrics. If you are using a remote license file, check /resizer.debug to see exactly what will be reported. By using a remote license you agree to have this information logged when your license file is fetched. We will not sell this information; we primarily use it to determine the focus of our development and optimization efforts.
