Msc-generator allows you to fine-tune the exact location of the arrow endpoints. There are two kinds of modification after you have selected an arrow end via blocks and ports.
+x<pixels>
or -x<pixels>
after the block and/or port/dir specification. You
can add either or both an X and an Y coordinate offset.
+x<percent>%
or -x<percent>%
. Note that this is a relative shift added to the
endpoint calculated from block and/or port/dir specification. Thus for example
a+x10%->b
will start the arrow from coordinate (a@60%, a@50%)
(a bit to the right
from the center of a
), since in the absence of a port the arrow starts from
the middle of the given block.
+<pixel>
(no x
or y
) or -<pixel>
. Negative values make the arrow shorter,
positive values longer. Lengthening of a curvy arrow is made by continuing it in a
straight line. You can also add a percentage, which is calculated from the
original length of the arrow.
You can mix and match any number of the above modifiers after the block/port/dir
specification - they will be cumulated and their order is irrelevant. The shift
operations will be applied first, then the length modifier ones. They can be combined
with both via
attributes and any routing algorithm.
