- fixed WmfExtTextOut dx handling for variable text spacing - fixed WmfExtTextOut text position for (0,0) references based on the current/last path location - fixed WmfExtTextOut handling of symbol/wingdings charset (move ascii to unicode private area, because Java font loader maps the glyphs there) - and use existing workaround if the fonts aren't installed, i.e. use corresponding unicode characters of the logcial font then - provide option in PPTX2PNG to use given file input type, if the file magic is unknown - provide option in PPTX2PNG to render text as shapes in SVG, as dx handling (above) implemented via TextAttribute.TRACKING is not supported by batik source of the sample.wmf, which I've used: https://stackoverflow.com/questions/58726194/svg-rendering-with-batik-produce-broken-image git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1876136 13f79535-47bb-0310-9956-ffa450edef68
