Summary: PDFGraphics2D.drawString(AttributedCharacterIterator it,

Product: Fop

PDFGraphics2D.drawString(AttributedCharacterIterator it, float x, float y)

A failing test is attached.
It looks like drawString(AttributedCharacterIterator it, float x, float y) is
not finished. The variable fontState which results in NPE is assigned to null
and never initialized.
If possible, I'd like to have it fixed in FOP 0.95. I would be happy to upload
a patch but my knowledge of PDF is not enough for that :). Please suggest how
it can be fixed.
Shouldn't this method be re-written so that drawString(String str, float x,
float y) is called for each individual text run in the AttributedString? If so,
how can I measure the length of a text run and advance the x co-ordinate?
Regards,
Yegor
