Tilman Hausherr updated BATIK-1109: ----------------------------------- Affects Version/s: 1.7 > svggen.font.SVGFont doesn't always calculate the correct path > ------------------------------------------------------------- > > Key: BATIK-1109 > URL: https://issues.apache.org/jira/browse/BATIK-1109 > Project: Batik > Issue Type: Bug > Components: SVGGraphics2D > Affects Versions: 1.7 > Reporter: Tilman Hausherr > > We at PDFBox have used the code at > https://svn.apache.org/viewvc/xmlgraphics/batik/trunk/sources/org/apache/batik/svggen/font/SVGFont.java?view=markup > for TT font rendering. There've been some problems (see PDFBOX-1435, scroll > to second half), and after bugfixes didn't work (see PDFBOX-1206), I had the > idea to create a SVG file by hand with the calculations mentioned in the file. > I calculated the SVG values for the outer circle of that "o" of PDFBOX-1435 > with the Batik source and added 100 to each y value (before I found out that > svg allows translating). Here's the svg file I get: > {code} > <?xml version="1.0" standalone="no"?> > <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" > "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"> > <svg width="12cm" height="12cm" viewBox="0 0 1200 1200" > xmlns="http://www.w3.org/2000/svg" version="1.1"> > <rect x="1" y="1" width="1000" height="1000" > fill="none" stroke="blue" stroke-width="1" /> > <g transform="scale(7)"> > <path d="M85,53 T74,49 T54,48.5 T39.5,59.5 T35.5,76.5 T44,94 T62,102 > T79.5,97 T89.5,82.5 T88.5,63 Z" > fill="none" stroke="red" stroke-width="5" /> > </g> > </svg> > {code} > This can be displayed with firefox, and this "o" has an angle :-( The reason > is that the Batik algorithm doesn't work for contours made entirely with > off-curve points. > I didn't actually run the Batik code, the calculations were done on paper. > Further thoughts on the TT path drawing algorithm can be found at > PDFBOX-1206. We ended up using the code from PDF.js, and maybe you should too > :-) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: batik-dev-unsubscr...@xmlgraphics.apache.org For additional commands, e-mail: batik-dev-h...@xmlgraphics.apache.org
