Pegasus Compression Engine Gets A Tune Up!TAMPA Fla.--(BUSINESS WIRE)--June 18, 1998--Pegasus Imaging Corporation, announces the release today of new version of the PICTools imaging libraries for software developers. PICTools which is used by many leading multimedia and imaging companies including iPIX, Pegasus Software LLC, Trellix, PictureVision, Mindscape, NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. , The Learning Company, Dataware, Konica, CompuServe and other industry leader offers C/C++ developers the fastest digital imaging available with maximum control over image processing. PICTools version 2.0, the first major update of the high speed PICTools toolkit in over 2 years, extends the features of PICTools low level image compression toolkit providing software developers access to the fastest commercial implementations of JPEG JPEG in full Joint Photographic Experts Group Standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. , CCITT See ITU. CCITT - Commite' Consultatif International de Telegraphique et Telephonique. (International consultative committee on telecommunications and Telegraphy). CCITT changed its name to ITU-T on 1 March 1993. Group3/Group 4 image data and many standard raster image formats including BMP (1) (BitMaP) Also known as a "bump" file, it is the native, bitmapped graphics format in Windows. A BMP can be saved in several color options: 1-, 4-, 8- and 24-bit color provide 2, 16, 256 and 16,000,000 colors respectively. BMP files use the .BMP or . , TGA, PCX (1) A bitmapped graphics file format that handles monochrome, 2-bit, 4-bit, 8-bit and 24-bit color and uses RLE to achieve compression ratios of approximately 1.1:1 to 1.5:1. Images with large blocks of solid colors compress best under the RLE method. See PC Paintbrush. , GIF GIF in full Graphics Interchange Format Standard computer file format for graphic images. GIF files use data compression to reduce the file size. The original version of the format was developed by CompuServe in 1987. , TIF, and PNG. "Our customers demand and receive complete control over the manipulation of the image data used in their applications," says Chris Lubeck, Director of Development. "PICTools provides an incredible feature set for handling data with awesome speed and the lowest memory and disk footprint possible." PICTools is a modular Application Programmers Interface (API) that can optionally access compressed DLLs for creating the smallest executable possible. The PICTools 32 bit toolkit supports multithreading, memory to memory image control, streams based processing, optional 16 bit built in thunking See thunk. layer and optional plug-ins for ePIC compression, lossless compression, wavelet compression, and medical compression. Pegasus' involvement with imaging standards including the X3L3 JPEG committee, JPEG 2000, JBIG, and the Snowbird compression conferences enables Pegasus to provide cutting edge enhancement to the JPEG, ePIC and Wavelet compression technologies. Aside from the MMX , DCT (Discrete Cosine Transform) An algorithm that is widely used for data compression. Similar to Fast Fourier Transform, DCT converts data (pixels, waveforms, etc.) into sets of frequencies. The first frequencies in the set are the most meaningful; the latter, the least. and Huffman speed optimizations within PICTools, Pegasus has added advanced JPEG features which are demonstrated on http://www.jpg.com including: -- Color Palette Optimization -- High Quality Image Zooming -- Enhanced JPEG speed/ 30 fps Motion JPEG -- Direct Compress/Decompression to and from YUV space -- Region of Interest Viewing -- Lossless Rotate/Recompress/Mirror -- Region of Interest Optimization / Compression -- Contrast / Brightness / Color / Tint Control -- Color to Grayscale In computing, a grayscale or greyscale digital image is an image in which the value of each pixel is a single sample. Displayed images of this sort are typically composed of shades of gray, varying from black at the weakest intensity to white at the strongest, though in Conversion All of these PICTool's enhancements mean better, faster imaging. Downloadable trial version toolkits are available from the Pegasus web site at http://www.jpg.com. On-line testing of the Pegasus JPEG implementation can be done by visiting the JPEG Wizard home page, http://www.jpegwizard.com. Current PICTools implementations include all Windows environments (3.1, 95, NT, 98), OS/2, Macintosh with custom ports available to other environments including PLDs, ASICs and DSPs. Pegasus Imaging was founded in 1991 as a digital imaging technology company and today provides development toolkits, imaging research, end user imaging tools and applications.
