I am having a problem with writing a Unix-created document to PDF using
iText. Unix output files don't use any fonts and there is minimal spacing
between lines (using the lpr output). My algorithm was to read each line
in from the original file and then write it to PDF landscape document with
the appropriate font (Courier) to preserve the alignment, just using code
like this:
String line;
PdfWriter.getInstance(document, new FileOutputStream(PDFname));
BaseFont bf1 = BaseFont.createFont("Courier", BaseFont.WINANSI,
BaseFont.EMBEDDED);
bf1.setDirectTextToByte(true);
Font font = new Font(bf1, (float)10, Font.NORMAL);
Document document = new Document(PageSize.A4.rotate(), 0, 0, 0, 0);
document.open();
document.setLinesRequired(56);
BufferedReader reader = new BufferedReader(new FileReader(inFile));
while ((line = reader.readLine()) != null) {
document.add(new Paragraph(line,font));
}
This didn't work since each *line* occupied a large height (twice the size
as the text height regardless of font). I wanted to adjust this but
couldn't. I saw a class in the API called com.lowagie.text.pdf.PdfLine
that has a height() method but no "get" methods to adjust the height.
Furthermore, there is no binding between PdfLine objects and the Document
class.
Next I tried mapping each page to a table so that all the cells would "fit".
The number of lines in each page of the unix file was 56. My code for
this looked something like:
String line;
cnt=1;
Document document = new Document(PageSize.A4.rotate(), 0, 0, 0, 0);
document.open();
BufferedReader reader = new BufferedReader(new FileReader(inFile));
Table datatable;
datatable = new Table(1);
datatable.setWidth(160);
datatable.setDefaultCellBorderWidth(0);
atatable.setDefaultHorizontalAlignment(0);
datatable.setDefaultRowspan(1);
datatable.setSpaceBetweenCells(0);
datatable.setBorderWidth(0);
datatable.setCellsFitPage(true);
while ((line = reader.readLine()) != null) {
BaseFont bf1 = BaseFont.createFont("Courier", BaseFont.WINANSI,
BaseFont.EMBEDDED);
bf1.setDirectTextToByte(true);
cell = new Cell(new Phrase(padStringWidth(line, 132), new Font(bf1, 10,
Font.COURIER)));
cell.setHorizontalAlignment(Element.ALIGN_CENTER);
cell.setVerticalAlignment(Element.ALIGN_TOP);
cell.setColspan(1);
cell.setRowspan(1);
cell.setNoWrap(true);
// cell.setBorder(Rectangle.NO_BORDER);
cell.setBorderColor(java.awt.Color.gray);
datatable.addCell(cell);
if (cnt == 56) {
document.add(datatable);
document.newPage();
datatable = new Table(1);
datatable.setWidth(160);
datatable.setDefaultCellBorderWidth(0);
datatable.setDefaultHorizontalAlignment(0);
datatable.setDefaultRowspan(1);
datatable.setBorderWidth(0);
datatable.setSpaceBetweenCells(0);
datatable.setCellsFitPage(true);
cnt=0;
}
cnt++;
}
Please note that I used cell.setBorderColor(java.awt.Color.gray) in order to
display the cell boundaries. In experimenting with different font sizes, I
noted that just as was the case with just lines, the text height only
occupied half the cell (the cell size increased proportionally along with
the font - just as with lines). I used various suggestions I saw previously
such as calling datatable.setBorderWidth(0),
datatable.setSpaceBetweenCells(0) datatable.setCellsFitPage(true) and none
of these worked.
The most promising suggestion I saw was from
http://article.gmane.org/gmane.comp.java.lib.itext.general/1225/match=line+h
eight which suggested using the height method of the Cell class (inherited
from Rectangle). height() is a "get" method so I instead thought of
working with the setBottom() & setTop() methods (inherited by Cell from
Rectangle). It compiled OK, but I got the run-time error:
java.lang.UnsupportedOperationException: Dimensions of a Cell are attributed
aut
omagically. See the FAQ.
at com.lowagie.text.Cell.setBottom(Unknown Source)
at TestPDF.putPDF(TestPDF.java:158)
at TestPDF.run(TestPDF.java:28)
at TestPDF.main(TestPDF.java:17)
Could you give me some suggestions as to how to adjust my application so
that I can reduce the height of a line (or cell) holding text.
Thanks for your attention.
