Reads and converts WSQ and 31 other formats
With regard to fingerprint images WSQ (Wavelet Scalar Quantization) is better than other lossy compression strategies, such as JPEG, plus was chosen by F (U. S. Federal Agency of Investigation) as the particular fingerprint image compression regular.
WSQ is really a lossy data compresion method which is well-suited with regard to preserving the high quality details of grayscale pictures while maintaining high data compresion ratios of typically twelve: 1 to 15: one.
Cognaxon WSQ image collection provides the easy method to add WSQ picture format support to your own software projects. WSQ picture library reads and changes between WSQ and thirty-one other graphic file types, it really is small (~ one. 5 Megabyte) and quick, and it has graphics format transformation utility.
Supported formats with regard to reading:
WSQ, BMP, JPEG, TIF, JPG, JPEG, JPE, PNG, GIF, PSP, JFIF, RLE, DIB, TGA, GET, VST, VDA, ICB, FAX MACHINE, EPS, PCX, PCC, SCR, RPF, RLA, SGI, RGBA, RGB, BW, PSD, PDD, PPM, PGM, PBM, CEL, PIC, PCD, CUT, IFF, ICO, WMF, EMF.
Backed formats for writing:
WSQ - FBIs Wavelet Scalar Quantization,
BMP - Home windows Bitmap Graphics,
TIFF -- Tagged Information File File format (no LZW compression),
PNG - Portable Network Images,
JPEG - Joint Photo taking Experts Group,
RGB -- Silicon Graphics International (uncompressed),
TGA - Truevision Cartello Graphic.
Adding WSQ picture library for your software task is very easy. Just 2-3 steps and many ranges of code are needed. Sample projects are provided for:
Microsoft Visual C / Microsoft Visual C. NET,
Microsoft Visual C#. NET,
Microsoft Visual Basic,
Microsoft Visual Basic. NET,
Borland C Builder,
Borland Delphi,
Sun Java,
MatLab,
Compaq Visual Fortran,
PowerBASIC.
