The app is currently available in English and it was last updated on 2012-01-28. The program can be installed on Linux, Win2000, Win7 x32, Win7 x64, Win98, WinMobile, WinServer, WinVista, WinVista x64, WinXP.
For fingerprint images WSQ (Wavelet Scalar Quantization) is superior to other lossy compression methods, such as JPEG, and was chosen by FBI (U.S. Federal Bureau of Investigation) as the fingerprint image compression standard.
WSQ is a lossy compression method that is well-suited for preserving the very high resolution details of grayscale images while maintaining high compression ratios of typically 12:1 to 15:1.
Cognaxon WSQ image library provides the easy way to add WSQ image format support to your software projects. WSQ image library reads and converts between WSQ and 33 other graphic file formats, it is small (~ 2 Megabytes) and fast, and has graphics format conversion utility.
Supported formats for reading:
WSQ, BMP, TIFF, TIF, JPG, JPEG, JP2, JPC, JPE, PNG, GIF, PSP, JFIF, RLE, DIB, TGA,WIN,VST,VDA,ICB, FAX, EPS, PCX, PCC, SCR, RPF, RLA, SGI, RGBA, RGB, BW, PSD, PDD, PPM, PGM, PBM, CEL, PIC, PCD, CUT, IFF, ICO, WMF, EMF.
Supported formats for writing:
