Archivo: Flag of Iran (official)

Descripción: The flag of Iran, created from scratch using the official geometric construction from ISIRI (translation at FotW). Note the irrational aspect ratio of ±1.7477:1, which is slightly different from the more often used 7:4 (1.75:1) given in the "simplified" construction sheet in the same document.Coordinates were computed numerically using a MATLAB script; colors were taken from File:Flag of Iran.svg. The tricolor flag was introduced in 1906, but after the Islamic Revolution of 1979 the Arabic words 'Allahu akbar' ('God is great'), written in the Kufic script of the Qur'an and repeated 22 times, were added to the red and green strips where they border the white central strip.The official ISIRI standard (translation at FotW) gives two slightly different methods of construction for the flag: a compass-and-straightedge construction used for this file and a "simplified" construction sheet with rational numbers used for File:Flag of Iran.svg.
