I am new to iText and am using version 1.2.
I'm very impressed with iText so far: congratulations to Bruno, Paulo and
the other folks that have helped make this a great package!
I spent a few hours generating a PDF and everything worked pretty much
exactly as I wanted. However, when I tried to generate the same information
in an RTF(2) document using largely the same techniques, except that I am
using Table and Cell in my RTF rather than PdfPTable and PdfPCell, I found
that spacing behaves very differently.
The best way to illustrate this problem is for you to run my program, which
is supplied below. All you need to do is this:
1. Change line 48, which sets OUTPUT_FILE_PATH_RTF, to write the file to a
path of your choice.
2. Ensure that line 35, which sets EXTRA_SPACING, sets the variable to
false.
3. Save the program and run it. This will produce the RTF using only the
standard iText methods to control spacing.
4. Change line 35 to set EXTRA_SPACING to true.
5. Save the program and run it. This will produce the same RTF but will add
extra spacing beyond those created by the standard iText methods.
As you will see, when you run the program with EXTRA_SPACING set to false,
the document is rather cramped and the standard methods like
Paragraph.setSpacingAfter() and Table.setPadding() seem to be completely
ignored. There are no spaces after each paragraph (beyond the fact that the
next paragraph starts on a new line) and there is no visible spacing within
or between the cells of the Table, despite using Table.setPadding(),
Table.setSpacing(), Table.setSpaceInsideCell(), and
Table.setSpaceBetweenCells(). In addition, list items for Recent Education,
Employability, and Experience are all run together on a single line instead
of each being on a line by themselves. Also, no bullets appear in those
lists.
If you run the program with EXTRA_SPACING set to true, the document improves
considerably in terms of the spacing between paragraphs. Also, list items
appear on separate lines, as they should. But no list bullets appear. Also,
I haven't been able to figure out how to change the spacing between the
tables. I'd like the first table to appear on the line immediately below the
EMPLOYMENT HISTORY title, then to have one or two blank lines between each
table, then to have one or two blank lines after the last table.
Also, I'm curious about Table.setWidth(). Initially, I set it to 100,
assuming that it would use the full width of the page. However, it only used
about 2/3 of the available page width. I got it to use the full width of the
page (and maybe even make the page wider?) by using a value of 150. Is that
working the way it is supposed to? When I used Table.setWidth(100) on the
PDF document, it used the full page width. 100 seems like the logical value
for that purpose. In fact, I would think that the setWidth() value should
never be greater than 100, unless perhaps a value of 100 means "use all
space between the Margins" while a value greater than 100 means "use all
space between the edges of the page, ignorning Margins".
Sorry for the long list of questions but they all seem related so I thought
it made more sense to ask them all at once rather than formulate several
smaller questions.
