Draw simple from command line or from file.

This application has been implemented to help generate visualization from debug printouts. Sometimes there are just too much information to see what numbers mean, and then visualization may help to see the big picture.

Requires Gempyre-Python to be installed.

• off x y - set offset of following coordinates. Default is (0,0) helps you centrify/move drawing.

• scale s - scales drawing with a given factor. Default is 1.0.

• line x1 y1 x2 y2 - draw a line.

• ln x y - draw a joint line from a previous line position.

• move x y - move a line start position. I.e. 'line x1 y1 x2 y2' and 'move x1 y1 ln x2 y2' are equal expressions.

• color c - use a given color (HTML color name or HTML color format).

• color c - use a given color (HTML color name or format).

• close - close current line to a polygon.

• circle r x y - draw a circle.

e.g.

$ pen.py off 1000 0 line 1322 12 1350 100 ln 1200 200

is pretty equal with

$ pen.py off 1000 0 move 1322 12 ln 1350 100 ln 1200 200

Read from file:

$ pen.py < lines.txt
