The American pica measure of 0.013837 ft.

The French pica of 12 Didot points (also called cicéro) generally is: 12 × 0.376 = 4.512 mm (0.177 in).

To date, in printing these three pica measures are used: He replaced the traditional measures of cicéro, Petit-Roman, and Gros-Text with “ten-point”, “twelve-point”, etc. The pica originated around 1785, when François-Ambroise “L'éclat” Didot (1730–1804) refined the typographic measures system created by Pierre Simon Fournier le Jeune (1712–1768). The pica contains 12 point units of measure. Source: WikipediaĪ pica /ˈpaɪkə/ is a typographic unit of measure corresponding to 1⁄72 of its respective foot, and therefore to 1⁄6 of an inch. As a result, the coordinates of (for example) sprites are always multiples of 0.05 (i.e. Sprites, movie clips and any other object on the stage are positioned with twips. They are also used in Rich Text Format from Microsoft for platform-independent exchange and they are the base length unit in and its fork LibreOffice.įlash internally calculates anything that uses pixels with twips (or 1/20 of a point). Twips are a commonly used unit with Symbian OS bitmap images and are also used internally in SWF format. Converting between twips and screen pixels is achieved using functions such as TwipsPerPixelX and TwipsPerPixelY. Twips are the default unit of measurement in Visual Basic (version 6 and earlier, prior to VB.NET). A pixel is a dot that represents the smallest graphical measurement on a screen.

A twip is defined as being 1/1440 of an inch.Ī pixel is a screen-dependent unit, standing for 'picture element'. Twips are screen-independent units to ensure that the proportion of screen elements are the same on all display systems. One twip is 1/1440 inch or 17.639 µm when derived from the PostScript point at 72 to the inch, and 1/1445.4 inch or 17.573 µm based on the printer's point at 72.27 to the inch.
