  • HD Photo (JPEG XR) - HDP, WDP
  • Provides support for fully standards based JPEG XR
  • Higher image quality, greater preservation of data and advanced features for today’s digital imaging applications
  • A still image compression algorithm for continuous tone photographic images
  • Features lossy and lossless compression, multiple colorspaces, a wide dynamic range, and extensive metadata support
  • Performance optimized
  • JPEG (Progressive)
  • JPEG (Sequential) – 24-bit RGB, 8-bit grayscale
  • Patented technology for enhanced JPEG decompression will remove block artifacts from over-compressed JPEG images without blurring
  • IPTC metadata support within JPEG
  • JPEG (Progressive) to JPEG (Sequential) Transcoder
  • JPEG 2000 - 24-bit RGB, 8-bit grayscale
  • Supports a user-configurable number of threads per operation for optimal throughput on multicore CPUs
  • Metadata support
  • JPIP Client/Server Technology for JPEG 2000
  • Ideal for large images
  • Provides sophisticated imaging technology enabling engineers to design and build a JPEG 2000 JPIP implementation wholly in accordance with the JPEG 2000, Part 9 standard
  • The JPIP standard is designed to speed optimize network viewing of user selectable resolutions and areas of interest on JPEG 2000 images
  • Provides a complete JPIP API for client and server side deployments, and provides JPEG 2000 compliant compression, JPIP request and receive, and decompression of JPEG 2000 images
  • The Accusoft Pegasus JPIP implementation benefits from many years of experience working with streamed multi-resolution image formats
  • Learn more about JPIP (here)
  • PCX
  • Camera RAW
  • Automatic detection and decompression of vendor-specific Camera RAW photos from Canon, Fuji, Kodak, Minolta, Nikon, Olympus and more (See list of makes and models)
  • PNG
  • TGA
  • TIFF
  • Metadata support
  • BMP
  • DCX
  • ePIC (Proprietary)
  • Supports PIC format compression, replacing the JPEG Huffman encoder with the proprietary ELS entropy encoder for 15% more compression
  • Can be losslessly converted back to JPEG format using Op_RORE
  • GIF / LZW
Image Editing & Processing

  • Advanced JPEG Editing within Compressed JPEG DCT Space
  • Provides JPEG editing directly on JPEG compressed data thereby avoiding the quality loss of recompression and color conversion normally associated with editing JPEG images (more)
  • Auto Red Eye Detection and Removal with Confidence Reporting
  • Adjust for glare, darkness, and red face
  • Decompresses the eye area, makes the corrections, recompresses the area, and replaces the area with the improved image
  • Remove compression artifacts
  • Auto Color Leveling
  • Color Conversion, Palette Creation, Rotation
  • Deskew
  • Overlap filter options
  • Post processing filter strength settings
  • Embedded orientation flags
  • Tiling
  • Subband control
  • EXIF Metadata Editing
  • Image Resizing
  • IPTC metadata support within JPEG
  • Regional Image Compression
  • Reduce compressed JPEG file size while preserving image quality by applying the optimal compression settings to one or more areas of an image
  • Reorient JPEG Images
  • Sub-Image Processing
  • Quickly decode and view a rectangle within a JPEG image without decoding the rest of the image data.
  • Buffer to buffer image processing for maximum flexibility
  • The high-performance API (Application Programmers Interface) offers total control of image processing functions
