ocr: TIFF. 5.0, Appendices Smooth images also compress beuer than noisy images, and simple images compress better than complex images. On a 68082- or 386-based computer, LZW software can be written to compress at between 30K and 80K bytes per second, depending on image characteristics. LZW decompression speeds are typically about 50K bytes per sccond. LZW works well on bilevel images, 1O. Italways beats PackBits, and, generally ties CCITT 1D (Modified Huffman) compression, on our test images, Tying CCITT ID is impressive in that LZW scems tol be considerably faster than CCITT 1D, at least in our im ...
