If you need anyway to create something which looks like checkered board,
then the pbm format is your friend.  Once you have created a pbm format
file (easy, and maybe there is already a suitable Perl model), the tools
in the netpbm package can convert it into any desired image format (pbm
and its brothers - pgm, ppm and pnm - was originally created as an
intermediate format for conversion between different image formats).

See also man netpbm.
