Specify the number of columns of molecules to be displayed
per page. The default value is currently two.
-nrow
Specify the number of rows of molecules to be displayed
per page. The default value is currently three.
-autofit
Automatically magnify small molecules to fill the
display area. By default, small molecules have a default bond length
such that most depictions of medicinal chemistry size molecules appear
at the same relative magnification in the page. With this option,
compounds such as cyclopropane are magnified to fill the available
canvas, rather than appear proportional to benzene (for example).
