9.0.0 Oct 28, 2020 iAuto 2021 We've introduced a new preset that brings together the best our of image correction technology!
Image Quality Improvements We've spent most of 2020 focusing on advancing our image correction quality, and have made a number of specific improvements:
  1. Better Sharpening, especially on print. We built a new sharpening system and carefully tuned it with our printing partners to ensure that photos of all sizes and contents are crisp and sharp.
  2. Skin Tone Preservation. New Skin & Depth Bias AUTO mode set with BIASMODE BIAS_AUTO.
  3. Better Highlights - better detail preservation when using Skin & Depth Bias at high strengths and new Highlights parameter to control Highlight preservation - most noticeable when using Exposure at high strengths. Set with PFCCOREPARAM.iHighlightPreservation
  4. Better overall tone and contrast due to an improvement in our Depth processing and algorithm
  5. New Super Contrast algorithm controlled via the PFCCOREPARAM.iLocalContrast parameter. This is designed to add depth and emphasize contours for amazing images.

Pre-built Command Line Utility We've taken our SDK, Sample code, and years of implementation feedback from dozens of customers and put this all together in a command line application that's included with each SDK license. This tool offers a simple, reliable and fast way to integrate Perfectly Clear into many existing photo workflows. The application supports a wide range of use-cases and is ready for immediate use in the most demanding production environments. • Other Major Improvements
  1. New support for Clipart detection using our AI-based image content detection using PFCREJECTOPTION
  2. New PFC_ApplyStrengthToParam() function to simplify a single 'Strength' slider like used in EyeQ desktop applications
  3. New PFC_GetRecommendedParam() function to quickly determine recommended exposure, and other “auto” parameters
