3.3.2 SQUAREXT

Syntax: SQUAREXT sidelength [ xoffset yoffset ]

The square extension, SQUAREXT, is the simplest extension. It simply draws a white square outline on a black background. SQUAREXT requires a single positive integer, sidelength, which specifies the size of the square to draw. It can also take the integer position arguments, xoffset and yoffset to move the square from the origin (center of the picture).

In the complete testlist below, each %I command creates one picture, which consists of a square outline drawn in white on a black background with a side length of 30 pixels, in varying positions around the origin.

%X[SQUAREXT.CXR] %M2%C2 %I[1,30,-50,-50] %I[1,30,50,-50] %I[1,30,50,50] %I[1,30,-50,50] #B[1,20]#R #B[2,20]#R #B[3,20]#R #B[4,20]#R

This example creates pictures like these:
