Cheatsheet

MetaPost

• Go in the relearn folder (for the terminal questions see: http://relearn.be/w/relearn-cheatsheet )
• cd relearn
• Clone (copy) the folder relearn.gesturing-paths and its Git history from OSP website
• git clone git@git.constantvzw.org:/relearn.gesturing-paths.git
• Run the program mpost on the file
• mpost nameoffileinthefolder
• It generates an EPS file: draw.1

• beginfig(1)
• draw (5,5) -- (0,30) --- (15,15) .. (30,30) -- (25,5) --- cycle;
• endfig;
• end

• -- → means a straight line between the coordinates
• .. → means a curved line between the coordinates
• --- → means a curved line with a “round” angle
• ... → aligns horizontally the two points (used for instance to make the bottom of a letter |_| on the baseline)
• cycle → links the last coordinate with the first one
• --- cycle; → means a curved line between the end and the beginning
• 
  

Tools

• fill instead of draw will fill the figure.
• withcolor will change the color.

Pen settings (the brush parameters)

• pen circle (round shape)
• pen square (square shape)
• pen razor (only a line without width)

• xscaled (scales horizontally)
• yscaled (scales vertically)
• rotated (rotates the pen)

• pickup pen circle scaled 0.8pt %(in MetaPost it will be postscript points)

• beginfig(1)
• draw (5,5) -- (0,30) --- (15,15) .. (30,30) -- (25,5) --- cycle;
• endfig;
• end

• pickup pen circle 
• xscaled 0.8pt
• yscaled 0.2pt
• rotated 45
• beginfig(1)
• draw (5,5) -- (0,30) --- (15,15) .. (30,30) -- (25,5) --- cycle;
• endfig;
• end

Using vector points

• draw (02,13)  {dir40}.. {dir20} (10,47);

• git pull
