Perl:Flags with Stars Tutorial
Drawing flags: reusing shapes.
We can move our polygon using the method offset(x,y). For example:
The flag of Vietnam has a yellow five pointed star on a red background. This star is a popular device on many flags, we define the star once and use it many times in later flags.
The given star has a radius of 100, it is centred on 0,0 which is the wrong place. We must translate to put it in the right place.
Bosnia and Herzegovina
The flag of Bosnia and Herzegovina includes 9 white stars. Each star is 38 right and 38 below the previous star.
