Bug ID: 106310
Summary: FILESAVE symmetric transition of Bézier point lost on
save
Product: LibreOffice
Version: 4.2.5.2 release
Hardware: x86 (IA32)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Draw
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: rb.hensc...@t-online.de
Disable any snapping. Create a Bézier curve with three anchor points. Set the
middle anchor point to symmetric transition. Save the document and reload it.
Examine the middle point. Does it still have a symmetric transition? If yes,
move its control points and save and reload again.
Working with such curves often leads to a corner point after reloading. The
reason is, that in that cases the path is not saved with the special path
command "s" for a symmetric transition, but with the generic "c" command.
So this is a weakness in implementation. It seems to use the coordinates to
determine whether it is a symmetric transition or not and fails because of one
off rounding inaccuracy. Instead it should use the state, which was set by the
user to determine a symmetric transition.
