Commutative diagram parameters

The following is a list describing the parameters used in the commutative diagram macros. These dimensions may be changed globally or locally.

\harrowlength

(Default: 60 pt) The length of right or left arrows.

\varrowlength

(Default: 0.618\harrowlength) The length of up or down arrows.

\sarrowlength

(Default: 60 pt) The horizontal length of slanted arrows.

\hmorphposn

(Default: 0 pt) The horizontal position of the morphism with respect to its default position. There are also the dimensions \hmorphposnup, \hmorphposndn, \hmorphposnrt, and \hmorphposnlft for ^/_ or \lft/\rt constructions.

\vmorphposn

(Default: 0 pt) The vertical position of the morphism with respect to its default position. There are also the dimensions \vmorphposnup, \vmorphposndn, \vmorphposnrt, and \vmorphposnlft for ^/_ or \lft/\rt constructions.

\morphdist

(Default: 4 pt) The distance of morphisms from slanted lines or arrows.

\channelwidth

(Default: 3 pt) The distance between double lines or arrows.

\hchannel, \vchannel

(Defaults: 0 pt) Overrides \channelwidth. The horizontal and vertical shifts between double lines or arrows.

\commdiagbaselines

(Default: \baselineskip=15pt \lineskip=3pt \lineskiplimit=3pt ) The parameters used by \commdiag for setting interline glue.

\hgrid

(Default: 15 pt) The horizontal spacing of the grid used by \gridcommdiag.

\vgrid

(Default: 15 pt) The vertical spacing of the grid used by \gridcommdiag.
