The image compression ratio can be chosen freely between lossless and very high compression. You can choose the reconstruction ratio as well. With lossless compression depending upon picture structure compression rates are achieved from 1:1,5 to 1:5. In this case only the specified amount of the data will be read from the file. LuraWave is based on the Wavelet technology and is ideally suitable for the digital photography, for picture files and eCommerce.
