[iText-questions] RE: spacing between paragraphs
I've some changes to the Paragraph and PdfDocument code in it seems to
work. Is there a set of JUnit tests I can execute to verify everything
is still ok?
In the meantime, I have created a new RFE and I have uploaded the
changed files over there. You can find them at
http://sourceforge.net/tracker/index.php?func=detail&aid=913453&group_id=15255&atid=365255
thanks,
Maarten

you do the code changes we'll consider it's inclusion.

Subject: [iText-questions] spacing between paragraphs
Hi,
Is it possible to extend the Paragraph API to allow users to
define some
empty spacing before and after a paragraph. I know this can
be done by
adding an empty paragraph with some leading before and after
the normal
paragraph, but it's not always that easy. For instance, I
have a method
addParagraph like this:
public void addParagraph(Document doc, String text) {
Paragraph p = new Paragraph(text);
doc.add(p);
}
If I now add an empty paragraph everytime I add a normal paragraph, I
could by accident let the next page start with an empty line if the
empty paragraph doesn't fit on the current page anymore. Or
even worse,
I could by accident add an empty page to the document if the normal
paragraph was the last paragraph of the document and was
placed at the
bottom of the last page. Also simulating spacing before a paragraph
begins by adding empty paragraphs can give similar problems: I don't
want a page to start with an empty line, so if the page starts with a
paragraph, the 'before spacing' of that paragraph should be ignored.
I think I can solve this myself if I could access the currentHeight
property of the PdfDocument class and use it to check if
adding spacing
before/after a paragraph is appropriate. Unfortunately, the
currentHeight property is private and there is no way to retrieve it.
Are there other alternatives to to solve my problem ?
I've seen some similar requests here on the mailinglist, so maybe it
would be nice if such methods could be added to the Paragraph API ??
Should I post a feature request at sourceforge, or doesn't it has a
chance to get accepted?
thanks,
Maarten Coene

Re: [iText-questions] PDF documents created by iText 1.02b doesn't look as good as with 1.00
Hi, JFreeChart was indeed adding some opaque lines to the chart. After removing these lines, the PDF documents looked fine. Thanks!

Re: [iText-questions] PDF documents created by iText 1.02b doesn't look as good as with 1.00
Hi, thanks for your help :-) I still have some problems with these generated PDF's: - is this opacity something of iText, or is it the responsability of JFreeChart and can I put it off with the iText API ? - I can't find a way to make these 2 PDF's look the same with Acrobat Reader 6 (however, they look the same with Acrobat Reader 5 !!!) Is it a specific setting within the reader I have to change, or can I change some PDF settings with the iText API to accomplish this? thanks, Maarten Paulo Soares wrote: There's nothing wrong. Only the text "serie 0" is really text, the other is composed of strokes (this is JfreeChart responsibility). The version 1.02b supports alpha blending in strokes. However, when opacity is present the viewer switches off line smoothing, That's why you see the text more blurred but if you magnify it you'll see that it's the same in both cases.
