angle:This is the average angle of the branch from its stem, and the average angle between each twig, and it's parent bough.
angvar:This is the maximum random variation allowed on the basic angle. Increasing this reduces the tree's symmetry.
depth:This is the number of divisions the tree's trunk makes, to the final twig. Making this larger, gives a more pleasing tree, but is memory hungry, and takes a long time to finish drawing.
pointed:Increasing this, increases the pointedness of the tree's canopy.
twig:This increase the length of branches. This is normally smaller than the canopy pointedness number.
canopy:When this paramater is high the tree's canopy looks fuller, but is more complicated. If this is high it takes a long time to draw and uses a lot of memory.
nol:Tree is drawn without leaves
fol:Tree is drawn with foliage.
pop:This draws a lombardy poplar type tree.
pol:Tree is drawn in a pollarded form.
weep:Hanging foliage is drawn.
stan:This causes the typical, standard type tree to be drawn.
cols:This influences the shades of colour used randomly.
leaf:This influences the leaf size in a random manner.
poplar:This paramater increases the height of this sort of tree.
pollard:This increases the number of main branches on the pollard.
leng:Adds a random factor to each branch.
draw:Creates and renders the DrawFile, of the tree.
