[iText-questions] Line widths in graphics
I am having a bit of a problem width line widths in graphics. I am using the Graphics2D interface to draw tree diagrams onto a template, which is then included in the PDF document. The diagrams consist of many lines all of the same width, but when viewed in Acrobat viewer the width of the lines is uneven, and varies with zoom level. I assume that this is due to the viewer trying to display lines on the lower resolution of the screen, but I'm wondering if there is any way to improve this? The document also contains tables. The borders on these tables stay an even width at all zoom levels - is there some trick I'm missing here?

[iText-questions] Creating new pages / page numbers
I am current creating PDF documents using absolute positioning of text and graphics, as described in chapter 10. I'm a little confused about how to start a new page, and how to get the current page number. At the moment I am calling: document.newPage(); which works, but only if something was actually written to the previous page. This is not a great problem, but is there anyway to force a new page? Is there a way to get the current page number? document.getPageNumber() always returns 0. I suspect that I'm misunderstanding what this function is supposed to do...

From reading the tutorial, it looks like I not use the Document class, and instead should do the text layout using columns, as this allows me call get/setYLine and thus stop and start text around the graphics. My next question is then how to handle tables. Given that I'll be using absolute position, it sounds like I need to use PdfPTables. What concerns me is how to split PdfPTables across multiple pages where necessary. Presumably, I need to look at each row and call "getRowHeight" to determine what will fit on a page, and then call writeSelectedRows appropriately. Would it be worth me attempting to develop a patch to allow relative link co-ordinates? cheers, Paul ___ Have big pipes? SourceForge.net is looking for download mirrors. We supply the hardware.

[iText-questions] Implementing image maps
Hi,
I am trying to implement image maps in a PDF document, so that areas of
a graphic link to other points in a PDF document.
I am creating the graphics using Graphics2D to create a PDFTemplate (as
per tutorial chapter10). I want to include the graphics inline, so I
then do:
document.add(new ImgTemplate(myPDFTemplate));
This much works very well.
My problem is in creating the link areas. I can use
PDFTemplate.localGoto("name", llx, lly, urx, ury), but these
co-ordinates are relative to the page, not the template. What I really
want to do is use co-ordinates relative to the lower left of the
template.
Is there a way around this? I can't see how to transform the
co-ordinates myself, as I don't know the absolute position where the
ImgTemplate will be placed.
cheers,
Paul

OK. What I was trying to do is make the logical font name "SanSerif"
resolve to be this particular TTF font, without registering that font
with the X server. I am intending to run this under jdk 1.4, running
with the "headless" option - I have yet to investigate how fonts are
registered in this case.

That works - many thanks.
I had tried this previously, but with:
mapper.putName("SanSerif", pp);
Like this, it does not work, with "sansserif" it does. Both ways, I
create the font in AWT using:
new Font("SanSerif", Font.PLAIN, 18);

Unfortunately, the EULA prevents us from redistributing these fonts with
our application. I have just realised that the Lucida font distributed
with Java is a TTF font, and contains a good range of characters, so
that may be suitable.
thanks for your help,
Paul

[iText-questions] Unicode fonts via PDFGraphics2D
I am trying to generate graphics for inclusion in PDFs which contain
the infinity symbol (unicode 0x221E).
I can get this to work in a normal paragraph:
BaseFont myFont = BaseFont.createFont(
"/home/shared/drop/fonts/arialuni.ttf",
BaseFont.IDENTITY_H,
BaseFont.EMBEDDED);
document.add(
new Paragraph(
"Infinity: \u221e",
new com.lowagie.text.Font(myFont, 12, com.lowagie.text.Font.NORMAL)));
but I can't get this to work via the Graphics 2D interface. From
looking at other mails on this list I understand that I need to tweak
the font mapper:
DefaultFontMapper mapper = new DefaultFontMapper();
mapper.insertDirectory("/home/shared/drop/fonts");
DefaultFontMapper.BaseFontParameters pp =
mapper.getBaseFontParameters("Arial Unicode MS");
if (pp != null) {
pp.encoding = BaseFont.IDENTITY_H;
}
What I can't do is actually select and use this font via the Graphics 2D
interface. I found part of a thread in the mailing list archives (which
is where I got the above code) but I couldn't find the beginning of the
thread.
A non-itext related problem that I have is that we will not be able to
distribute the MS Arial Unicode font as part of our application. Can
anyone suggest an alternative source for a font containing the infinity
symbol?
cheers,
Paul
