Also, FlashPix resolutions are pre-rendered as separate images stored together with original in a pyramid. Results in larger and slower compressed image. Selective Decompression Instantaneous viewing of massive images locally and over networks Only decompress the portion of the image user requests. MrSID Selective Decompression is a patented process. Pan and zoom around a single high resolution image instead of shuffling many small images.
Size is no longer a constraint.
MrSID Seamless Wavelet Compression is a patented process. Other wavelet compressors are not seamless. Compress an Image of Virtually Any Size. The only limitation to the size of image you can compress is the limitations of your operating system. The largest single image compressed with MrSID to date is 37 Gigabytes.
