special character in pdf

[contiang]

Hi everybody,

 

I need to display mathematical symbols in PDF. Especially superscript and subcript. I am using jasperreports to generate my pdf document. Anyone can tell me how to do it? Thanks.

The styled text attribute offer support for both subscript and superscript. Use isStyledText="true", and then feel free to use tags for your symbols.

 

hth,

Could you please explain how to use tags. For example i want to display e=mc^2 with 2 is the super script.

Hi,

 

There are <sup /> and <sub /> tags for superscript and subscript allowed in a styled text.

You could write your expression as:

Code:

E = mc<sup>2</sup>

For more information, please consult our [url=http://www.jasperforge.org/index.php?option=com_docman&task=doc_details&gid=57]Styled Text Report Sample.

Hi --

 

Of the 14 built-in fonts for PDF, your best bet is probably Symbol for the math fonts. I use ZapfDingbats a lot, but that does not have the math stuff.

 

You might see if you can find what the Symbol fonts are for the various characters, then set your pdfFontName="Symbol" for the characters that you want to output as math symbols.

 

If Symbol does not have what you want, you will need to find a font file and put that in your path and set the pdfFontName to that file, and set isPdfEmbedded="true" to be sure that the font is included with the pdf and everyone opening the PDF will have the font.
