{{#vardefine:pixel|128}}


Syntax

{{Coordinate to Pixel
 | <Value> (0.0 to 102.8)
 | <Direction> (N E S W)
 | <Scale> (128, 256, 512, etc)
 | <Offset> (Half point image width rounded up, minus any border width)
}}

For example: 

{{Coordinate to Pixel|10.5|N|128|3}}

gives the result:

{{#vardefine:pixel|128}}

{{#var:pixel}}



112
