    • AIX
    • MAC OS X

機能

圧縮とファイル形式

  • WSQ - Wavelet Scalar Quantization
    • Reduces file size varies based on compression technology used.

      The benefit of WSQ fingerprint-specific compression is reduced file size. A sample fingerprint with a resolution of 589 pixels by 605 pixels, 8-bit grayscale results in a file size of 325 KB when compressed with the standard lossless compression technology LZW. When compressed with lossy JPEG the file size is 108 KB. When compressed with PICTools, the file size is 28 KB. This is a space savings of greater than 11X over lossless compression, and almost 4X over JPEG when targeting consistent quality settings.

  • JPEG (Sequential) : 24-bit RGB, 2 to 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-LS : 24-bit RGB, 2 to 16-bit grayscale
    • Provide excellent lossless or near-lossless compression performance over a broad range of images
    • Programmatically set compression for lossless or near lossless, and point transform
    • Compress and decompress single component 2 to 16-bit grayscale images
    • Compress and decompress multiple component 24-bit (RGB) images
    • Compress and decompress 24-bit (RGB) images in any of three modes: Non-interleaved, line-interleaved, or sample-interleaved
    • Encode/decode application (APP), Comment (COM), and Restart (DRI, RST) Markers
    • Supports image cropping
    • Strictly adheres to the JPEG-LS specification
  • Lossless JPEG : 24-bit RGB, 2 to 8-bit grayscale
  • PCX
  • TGA
  • TIFF
  • BMP
  • DCX
  • GIF / LZW
  • HD Photo (JPEG XR) - HDP, WDP
    • Offers higher image quality, greater preservation of data and advanced features for today's digital imaging applications
    • A still image compression algorithm for continuous tone image data and features lossy, as well as lossless, compression, multiple color spaces, a wide dynamic range, and extensive metadata support
    • Implementation in PICTools is 40% to 60% faster than Microsoft's shipping HD Photo DPK

カラー画像処理と編集

  • Delivers buffer to buffer image processing for maximum flexibility
  • Includes the high-performance API (Application Programmers Interface) offers total control of image processing functions
