The column ISO 8859-1 shows how the file signature appears when interpreted as text in the common ISO 8859-1 encoding, with unprintable characters represented as the control code abbreviation or symbol, or codepage 1252 character where available, or a box otherwise. In some cases the space character is shown as ␠.
Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that the decrypted information appears as a visual image. One of the best-known techniques has been credited to Moni Naor and Adi Shamir, who developed it in 1994. [1] They demonstrated a visual secret sharing ...
It also works to "fall back" or replace 8-bit bytes using the appropriate code-point for a legacy encoding when errors in the UTF-8 are detected, allowing recovery even if UTF-8 and legacy encoding is concatenated in the same file. Prefix code: The first byte indicates the number of bytes in the sequence. Reading from a stream can ...
HTML is a markup language that defines the structure and presentation of web pages. It is one of the core technologies of the World Wide Web, along with CSS and JavaScript. HTML allows creating and formatting text, images, links, tables, forms, and other elements on a web page. Learn more about the history, syntax, and features of HTML on Wikipedia.
Binary translation. In computing, binary translation is a form of binary recompilation where sequences of instructions are translated from a source instruction set to the target instruction set. In some cases such as instruction set simulation, the target instruction set may be the same as the source instruction set, providing testing and ...
In the document-scanning industry, this is often referred to as "bi-tonal". A binary image is one that consists of pixels that can have one of exactly two colors, usually black and white. Binary images are also called bi-level or two-level, Pixelart made of two colours is often referred to as 1-Bit or 1bit. [2]
Dilation (usually represented by ⊕) is one of the basic operations in mathematical morphology. Originally developed for binary images, it has been expanded first to grayscale images, and then to complete lattices. The dilation operation usually uses a structuring element for probing and expanding the shapes contained in the input image.
Without proper rendering support, you may see question marks, boxes, or other symbols instead of Braille characters. The Unicode block Braille Patterns (U+2800..U+28FF) contains all 256 possible patterns of an 8-dot braille cell, thereby including the complete 6-dot cell range. [3] In Unicode, a braille cell does not have a letter or meaning ...
