Questions tagged [zigzag]

The term "zigzag", in graphic design, describes a line composed of small lines in which any pattern of two small lines have the same length and form equal angles relative to any other patterns in the zigzag. The term also is the name of an encoding system for integers.

Zigzag offers an attractive and mention-able separators in some design approaches. The first Zigzag widely drawn was made by ancient Egyptian in hieroglyph writings.

zigzag example which depicts water.

From "Signed Types" on Encoding - Protocol Buffers - Google Code:

ZigZag encoding maps signed integers to unsigned integers so that numbers with a small absolute value (for instance, -1) have a small varint encoded value too. It does this in a way that "zig-zags" back and forth through the positive and negative integers, so that -1 is encoded as 1, 1 is encoded as 2, -2 is encoded as 3, and so on
