Inserting Line Breaks into PDF

Is there a way to force line-breaks in pdf acro fields?

It did not work, because the content (input coming from parsed html file) had \r\n in it, but somehow it does only work with \n so I did the following:

content.replaceAll("\\\\r\\\\n", Chunk.NEWLINE.getContent()); // 2nd param is just "\n"

This fixed my issue.

FPDF Python Package to Write PDF Files - Inserting extra line breaks. Does this for Multi_cell and cell. Want to remove extra line breaks

The width in multi cell call, the first parameter is cell size or width. In portrait set that to something like 190. The second value actually controls spacing between lines so set to a value like 1 or 2. Set justification to left.

Generating line break in FPDF

You can use a MultiCell method descrypted in documentation as

This method allows printing text with line breaks. They can be
automatic (as soon as the text reaches the right border of the cell)
or explicit (via the \n character). As many cells as necessary are
output, one below the other. Text can be aligned, centered or
justified. The cell block can be framed and the background painted.

This method can take some argument

MultiCell(float w, float h, string txt [, mixed border [, string align [, boolean fill]]])

More information you can find on the http://www.fpdf.org in manual section.

In your case you can use it with line

//example parameters - use anything that suit your things
$width = 100;
$lineHeight = 4;

$pdf->MultiCell($width, $lineHeight, "{$pdf_observations}");

In this example if your string can't fit to provided width then the rest of the string will be brake into new line when every line have provided height.

How to insert line breaks in a PDF generated with XSL-FO

It should work with the following xml (you should add all the attributes):

<xsl:template match="AddCmt">
    <fo:block keep-together="always"> Additional Comments 
        <fo:block-container border-style="solid" height="20mm" width="170mm" space-after="5mm"> 
            <fo:block wrap-option="wrap" linefeed-treatment="preserve" white-space-collapse="false" white-space-treatment="preserve"> 
                <xsl:attribute name="id"> 
                    <xsl:value-of select="../CMT_ID"/> 
                </xsl:attribute> 
                <xsl:value-of select="../ANS_CMT"/> 
            </fo:block> 
        </fo:block-container> 
    </fo:block> 
</xsl:template> 

But as I mentioned in the comments, if your XML already has no linebreaks, there's no way your PDF will. You mentioned in your question there are no linebreaks in your XML, hence no linebreaks in the PDF.

Try checking out why there are no linebreaks in the XML. If you can provide any more information (a piece of your XML, the code you use to construct the XML, ...), please edit your answer and add the information.

How to Insert a Linefeed with PDFBox drawString

The pdf format doesn't know line breaks. You have to split the string and move the text position to the next line, using moveTextPositionByAmount.

This is not a special "pdfbox-feature", it is due to the pdf format definition; so there is no way for drawString and there are also no other methods to be called that support linefeeds.
