Sharp Suits. Apps & Services : Adobe Creative Cloud. Home - Sharp Suits. Fast Company. QR Code and 2D Code Generator | Kerem Erkan. This page is an online two dimensional code generator which is written in PHP. It can generate QR Code, Data Matrix, Aztec Code and Micro QR Code for the time being. Because QR Code is much more popular than the other code formats, it is separately named in the page title. If you need more information on two dimensional bar code systems, I strongly suggest that you take a look at Roger Smolski‘s comprehensive blog on QR Code and two dimensional bar codes.
Using the form on this page, you can create two dimensional code images that trigger various actions on the scanner device. Don’t forget to install Qrafter or Qrafter Pro (why two versions?) Please be sure to read the Notes and FAQ sections below before requesting help in the comments if you encounter any problems with code generation (Especially for Micro QR Codes or backslash characters you may encounter on some codes!). This page is very popular and because of that, it gets an incredible amount of comment spam. Notes: A4 paper format / International standard paper sizes. By Markus Kuhn Standard paper sizes like ISO A4 are widely used all over the world today. This text explains the ISO 216 paper size system and the ideas behind its design. The ISO paper size concept In the ISO paper size system, the height-to-width ratio of all pages is the square root of two (1.4142 : 1). The ISO paper sizes are based on the metric system. ISO 216 defines the A series of paper sizes based on these simple principles: The height divided by the width of all formats is the square root of two (1.4142).
For applications where the ISO A series does not provide an adequate format, the B series has been introduced to cover a wider range of paper sizes. The width and height of a B format are the geometric mean between those of the A and the next larger A(−1) format. Note: The geometric mean of two numbers and is the square root of their product, ()1/2, whereas their arithmetic mean is half their sum, (+)/2.
