Hi all,the following is, what I have found so far, but it might have errors. So please correct me.
If two lines build a corner, the corner-style can be None, Rounded, Beveled or Mitered. That is the property "draw:stroke-linejoin" in ODF and "stroke-linejoin" in SVG. But SVG has the additional property "stroke-miterlimit". Using it, the author can determine how sharp the corner can be before it is turned into kind Beveled. I see no such property in ODF. LibreOffice turns automatically to kind Bevel using the default value of svg:stroke-miterlimit.
The API has the struct "StrokeAttributes" in css::rendering. It has the element "MiterLimit". I do not know any UI for it and don't know, if and how it is usable at all. The service "LineProperties" in css::drawing does not provide such property.
In OOXML it is the attribute "lim" in element a:miter (20.1.8.43).This svg-attribute is read on SVG import. And it could be evaluated by the method basegfx::tools::createAreaGeometry(), if it got a value into the already prepared parameter. But between these two ends there is currently no way to transport the information. The line properties Width, Color, LineCap and LineJoin are transported via class "LineAttribute".
So my question is, how to transport the "Miterlimit"-information? Add a member to class LineAttribute?Add a member to PolygonStrokePrimitive2D and an additional new parameter into the chain of calls and constructions? Only fix svg-import or care for other things too? What would I have to consider?
Kind regards Regina
