Entries in a hash table are referenced using a hash value Figure 151 illustrates the structure of a hash table The hash value is generated from a key by using a hash function A hash function takes a key as input and returns an integer value within some fixed range The ash value is used as an index into an array that contains a list of objects with the same hash value A good hash function should distribute the possible key values evenly across the range of index values Since we are dealing with pixel values that have an equal probability of occurring, we can use a simple hash function which returns values in the range 02 3N - 1 const int mask = (1<<N) - 1 ; unsigned int Hash (unsigned char v1, unsigned char v2, unsigned char v3) { return (v1 & mask) | ((v2 & mask) << N) | ((v3 & mask) << (2 * N)) ; } The big problem with a hash table, especially in PNG compression, is how to handle entries with the same hash value This is known as a hash collision Unless we create a hash table with 16 million entries, something that may be feasible in a few years, we are going to have different 3-byte sequences with the same hash value In addition, we are counting on having identical 3-byte.

Sometimes, the DataSet object directly communicates with the APIs provided by a database management system. Uses the typed programming characteristic of XML. Data is selfdescribing because names for code items correspond to the "real-world" problem solved by the code. The underlying data constructs, such as tables and rows, do not appear, making code easier to read and write. Transmits a DataSet with an XML file. The XML format places no restrictions on data.Related: Java PDF417 Generation , EAN-8 Generating Excel , Codabar Generator ASP.NET When a Code 128 image is generated in C#, user-friendly interface for the encoder allows developers to easily adjust various barcoding settings, and produce images with a fixed size. div>. 3.
