Perl
ImageMagick convert Images from one format to another
IntroductionA Picture speaks louder than a thousand words. Most of the programming problems I usually worked with and involved in where dealing with just TEXT. So now I wanted to programatically work with images. I needed to warp, rotate, scale, stretch, convert from jpeg to png, png to jpeg, jpeg to bmp, bmp to jpeg etc. So I decided to search on how to do such a thing easily. Well the first obvious answer is to do handle all ...

in the
ASCII code. 64 different characters implies 6 bits as the word length. (no: of bits to represent a character)(2^6=64). So the encoding method is to group the binary data in groups of 6 bits. 10001010010010011110101101010100100100111000101001001001111010110101010010010011Now the grouped 6 bits words are represented by letters, digits and punctuations. A table is defined to denote the mappings of the bit pattern to a corresponding character. Here is a sample of base64 encoding ...

Fun with UNICODE and Mirroring Character
What is UNICODE?Everything you see on your computer is represented by 0's and 1's. Characters are also encoded in the form of 0's and 1's. In this method each character is represented by a number. A common method of encoding is called
ASCII (American Standard for Information Interchange). In this method each character is represented by 8 bits. Therefore 256 different characters can be represented using this method. But 256 characters ...
