Embedding Type1 fonts in PDF documents

2003-10-15 05:51

Hi Teodor.

 

I noticed, that it is not possible to embed type1 fonts in PDF documents. I analyzed the source code and found out, that you only pass the afm-part of the font to BaseFont.createFont. For Type1-fonts you have to pass the pfb-part of the font instead of "null".

 

Therefore I propose this patch for the class JRPdfExporter, which is working well for me:

 

 

patched jasper-reports-version, it now can also embed type1-fonts, which wasn't possible before:

 

modifications:

in class dori.jasper.engine.export.JRPdfExporter

in method exportText

 

at line 1097 added declaration to other declarations:

 

byte[] pfbbytes = null;

 

at line 1107 added after try-segment for loading the font:

 

try

{

n = jrFont.getPdfFontName();

if (n.substring(n.length()-3).equals("afm"))

{

loc=n.substring(0,n.length()-3) + "pfb";

pfbbytes = JRLoader.loadBytesFromLocation(loc);

}

else

pfbbytes = null;

}

catch(JRException e)

{

throw new JRException("Could not load pfb-font from location :

" + loc);

}

 

after that changed creation of BaseFont-object ('pfbbytes' was 'null' before):

 

baseFont =

BaseFont.createFont(

jrFont.getPdfFontName(),

jrFont.getPdfEncoding(),

jrFont.isPdfEmbedded(),

true,

bytes,

pfbbytes

);

 

I hope I could help with my patch ;-)

 

Thomas.
