Public bug reported:
Binary package hint: xfig
I discovered, when exporting to ps/eps/pdf (+latex) with xfig/transfig
3.2.5 there is some whitespace introduced between the arrow tips and the
boxes.
A friend of mine reported this to the author and got following reply:
"That bug was just fixed recently in transfig, but hasn't been released yet.
I have attached a patch file to fix the problem. If you need help patching
the source, please write again and I'll explain the process.
Thanks for using xfig."
file: patch.arrows
This fixes the bug where arrow heads fell short of the intended endpoint
This is to be applied to 3.2.5_alpha7 to make alpha8
