Julien Lacour commented on FOP-3135:
------------------------------------
I've tested with FOP 2.8 with {{fop -fo ..\test\tspan.fo ..\test\tspan.pdf}}
ant the following FO:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<fo:layout-master-set>
<fo:simple-page-master master-name="sample">
<fo:region-body/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="sample">
<fo:flow flow-name="xsl-region-body">
<fo:block>
<fo:external-graphic src="tspan.svg"/>
</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
{code}
But the output seems quite correct, just a little truncated in the bottom part.
I will analyze on my side again to see if I find the problem, maybe I use a
different batik.

> We have found an issue in FOP when transforming PDFs with SVGs containing
> <tspan> with multiple @x and/or @y attributes values.
> The problem is located in
> org.apache.fop.svg.PDFTextPainter.writeGlyphs(FOPGVTGlyphVector,
> GeneralPath), the positions given by x and y are never used when set.
> A possible fix for this issue is the following:
> {code:java}
> for (int i = 0, n = gv.getNumGlyphs(); i < n; i++) {
> int gc = gv.getGlyphCode(i);
> int[] pa = ((i > dp.length) || (dp[i] == null)) ?
> paZero : dp[i];
> if (gv.getGlyphPosition(i) != null) {
> Point2D gp = gv.getGlyphPosition(i);
> double x = gp.getX() - initialPos.getX();
> double y = -(gp.getY() - initialPos.getY());
> double xd = x - xoLast;
> double yd = y - yoLast;
> textUtil.writeTd(xd, yd);
> textUtil.writeTj((char) gc, true, false);
> xc = x + pa[2];
> yc = y + pa[3];
> xoLast = x;
> yoLast = y;
> } else {
> double xo = xc + pa[0];
> double yo = yc + pa[1];
> double xa = f.getWidth(gc);
> double ya = 0;
> double xd = (xo - xoLast) / 1000f;
> double yd = (yo - yoLast) / 1000f;
>
> textUtil.writeTd(xd, yd);
> textUtil.writeTj((char) gc, true, false);
> xc += xa + pa[2];
> yc += ya + pa[3];
> xoLast = xo;
> yoLast = yo;
> }
> }
> {code}
> I also attached an example for testing, it can be opened in Batik for
> comparison.
