TAB. 2 – Default values for colors.
For the almost all the commands, when a position or a length has to be given, two different
ways of giving it are availabel. First of all, of course, it is possible to give an absolut (intager)
value. But you can also provide a fraction. The value of this fraction will depend on the value of
the DrawWidth and DrawHeight constants. For example, 1/2 given for an horizontal position will
return half the value of DrawWidth. The fraction can be whatever you want between 0 and 1/1.
There some exceptions. Particularly for big arrows or circles, where only an absolut value is
necessary.
Moreover, when scaling an object is requested, it is possible to give, for one or both of the
requested dimensions, an integer smaller than 1. This will result in a scalling action keeping the
ratio height/width for the scaled object. If both width and height are integers smaller than 1, the
given object will not be scaled.
7 Rotations
When an angle is requested for a rotation, it must be an integer value between -180 and 360.
Other values will be accepted, but the resulting operation can not be predicted.
8 Positioning an object in relation to a root position
For a great number of graphical operations, both an horizontal position and a vertical position
are requested. Their values can be l, c or r for the horizontal position and t, c, b for the vertical
position. These symboles mean respectively left, center, right, top and bottom. For example, If
{l}{b} is used, the given object will be printed on the left and at the bottom of the root position,
which is equivalent to say that the root position will be located at the top right corner of the object.
If this positionning operation is followed by a rotation, the center of this rotation is the root
position.
