Description ben.a.hetland 2003-04-02 21:26:11 UTC 
Some diagrams use linestyles other than solid, for instance dashed and 
dotted lines in UML diagrams. These look OK on screen, but when they are 
printed _all_ lines become solid. Annoying since this is of semantic 
importance in UML.

My suspicion goes to the use of the Win32 renderer which is used for 
printing. The Win32 API does NOT support linestyles other than for hairline 
width (=0) lines, any lines wider than this silently become solid. A 
limitation in the API I presume, but it means that other linestyles 
actually have to be simulated in the application itself! (Or in this case, 
the renderer.)

For NT based windoze this can be overcome by (PS_GEOMETRIC | PS_USERSTYLE)
and a list of 'dashes' (dash lengths). There is some code of mine which 
does this in gdk/win32.
I'm not sure though, if is such a good idea to make Dia's wmf renderer 
output platform dependent ...

Changed my mind : now platform dependent only when printing

2004-07-04  Hans Breuer  <hans@breuer.org>

	* plug-ins/wmf/wmf.cpp : finally do extended linestyles if the
	windoze platform supports them. This should fix bug #109818, at
	least for the majority running NT or above ...
