Dear Tilman.
I tried to remove the font file item from the font descriptor, but apparently
this has no effect in the generated file
PDFontDescriptor fontDescriptor = pdFont.getFontDescriptor();
COSDictionary cosObj = fontDescriptor.getCOSObject();
Set<COSName> fontNameSet = new HashSet<>();
for(COSName name : cosObj.keySet())
{
if(name.getName().startsWith("FontFile"))
{
fontNameSet.add(name);
}
}
for(COSName name : fontNameSet)
{
cosObj.removeItem(name);
}
Your code looks good. But did you save the file first, reloaded it and
THEN did this, and then resaved the file? I'm not sure if I mentioned
this, if not, sorry.
To get the fonts for each page, get your PDPage objects, from the the
resources, from there the font names, then get the fonts through their
names.

Thank you for you answer, Tilman.
As I would like to try to remove the embedded fonts from the PDF file, Is it
possible to do it using a PDFBox code?
Yes; from a PDFont object, then get the font descriptor, then can call
.getCOSObject() on it and then manipulate from there, i.e. remove FontFile /
FontFile2 / FontFile3 from the font descriptor.

It might be possible to create your own different encoding as
described in page 264 of the PDF specification, and delete the
embedded font later. I haven't tested it and won't do it, and here's
why: you should embed your fonts. Not embedding might result in weird
effects with some viewers, e.g. getting different glyphs, squares or
nothing at all. So it would be several hours of work to create a bad
PDF file with some code that is hard to understand.
Are you aware that you can embed subsets? These are much smaller than
full fonts. Use PDType0Font.load().

Good morning.
I'm currently using PDFBox to build documents for the company I’m
working for, and I need to print strings with generic character, also
non in the WinAnsiEncoding range (e.g. “ł”).
And I shouldn’t embed fonts in the PDF documents.
If I use the internal PDFBox fonts (e.g. PDType1Font.HELVETICA)
apparently no fonts are than embedded in the document.
So I assume that the document, when displayed, refers to Fonts
present in the PC (Arial?); nevertheless
PDPageContentStream.showText() throws an IllegalArgumentException for such
“special” characters.
Using iText I could use the following call:
*Font myFont = com.itextpdf.text.FontFactory.getFont(name, size,
style, color);*
Using variable “myFont”, now I can refer to the font with no font
embedding, and I can use also non-WinAnsiEncoding characters.
Is there any way or workaround in PDFBox to generate a file with no
embedded files and with “special” characters?
If not, will it be possible in one of the next PDFBox releases?
Thank you very much in advance,
Fabio Vassallo
