Hi,
thanks, you had a look at it.
You are right, the leading is applied on the paragraph level by either
using my version of the
HtmlWorker (no change here, I think):
private static void setParagraphLeading(Paragraph p, String
leading) {
if (leading == null) {
p.setLeading(0, 1.5f);
return;
}
try {
StringTokenizer tk = new StringTokenizer(leading,
" ,");
String v = tk.nextToken();
float v1 = Float.parseFloat(v);
if (!tk.hasMoreTokens()) {
p.setLeading(v1, 0);
return;
}
v = tk.nextToken();
float v2 = Float.parseFloat(v);
p.setLeading(v1, v2);
} catch (Exception e) {
p.setLeading(0, 1.5f);
}
}
Stylesheet:
...
loadTagStyle(HtmlTags.BODY, ElementTags.LEADING, "0 1.1");
loadTagStyle(HtmlTags.BODY, ElementTags.SIZE, "9.5pt");
...
Title-paragraphs are produced by calling:
Paragraph titlePara = new Paragraph("", aFont);
titlePara.setLeading(aFont.getSize()+1);
Hmm, i would have thought, that the first line after setting a new
rectangle to a columnText would ignore the leading to produce a properly
aligned first line?

Let's assume that you have defined the same Y coordinates for
both columns, and that you didn't apply any transformations
in-between.

OK, I'll take your word for that.

In other words: you're working in composite mode, NOT in text mode.
The leading of the column is ignored.
iText will only look at the properties of the elements.
You already know that because you've read the book.

OK.

Sounds like a problem with the leading of the elements that were added.

Depending on the leading of the elements that were added.

OK.

The images clearly show that the text has a different font size, and
apparently also a different leading.

It doesn't really depend on the fonts.
It depends on the leading.
The leading (sometimes) depends on the font size.
It depends on how you define the leading of the element.

See above: how did you apply the leading?
