Description
In OpenOffice Draw, draw a single horizontal black line with the default width (0.5).
File -> Export -> WMF.
Run the resulting WMF through WMFTranscoder.
In the resulting SVG there is an extremely small stroke width (0.0378) that makes the line invisibly thin when opened in OpenOffice and in Firefox:
<g font-size="0px" stroke-width="0.0378" stroke-linecap="butt" stroke-linejoin="round"> <path fill="none" d="M90.2173 112.8945 L420.6992 112.8945"/> </g>
If I remove the "stroke-width" attribute, the line appears at its normal thickness.
