Subject [jira] [Commented] (PDFBOX-4645) impossible to use own TrueTypeFonts in acroForm (and font also not embedded)
Date Fri, 06 Sep 2019 14:16:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16924279#comment-16924279
] 

André Hertwig commented on PDFBOX-4645:
---------------------------------------

i created some other tests ... the solution was to set the embedSubset parameter to false
at the "load" method, afterwards it worked ...
{code}
PDResources formResources = acroForm.getDefaultResources();
try (InputStream defaultTTFont1 = new FileInputStream(myFontFile)){
	
	PDFont font2 = PDType0Font.load(pdfDocument, defaultTTFont1, false); // last parameter has
been changed to false
	COSName fontName = formResources.add(font2);
}
acroForm.setDefaultResources(formResources);
{code}

> Hi
> I have a PDF form and want to add additional fonts, because the default fonts does not
allow cyrillic or greek chars for example.
> I add the font as following (LiberationSans-Regular):
> {code}
> PDResources formResources = acroForm.getDefaultResources();
> try (InputStream defaultTTFont1 = new FileInputStream(myFontFile)){
> 	
> 	PDFont font2 = PDType0Font.load(pdfDocument, defaultTTFont1, true);
> 	COSName fontName = formResources.add(font2);
> }
> acroForm.setDefaultResources(formResources);
> {code}
> I debugged it, the valiable ttf is set.
> When filling a text field with for example cyrillic letters an exception occurs, than
I change the defaultAppereance of that field using the initially added font.
> But the original TTF will not really used, instead there wil be created new font classes
with a TTF of null, so it seems to be impossible to use a different TTF.
> Furthermore the font will not be embedded in the resulting PDF.
> {code}
> PDCIDFontType2.<init>(COSDictionary, PDType0Font, TrueTypeFont) line: 75	<-
initialized with TrueTypeFont = null

> As a result of this behavoir I get the following warning:
> {code}
> WARN  org.apache.pdfbox.pdmodel.font.PDCIDFontType2 - Using fallback font LiberationSans
for CID-keyed TrueType font LiberationSans-Regular
> {code}
> When opening the PDF afterwards, I will get an error from AcrobatReader, that the font
"LiberationSans-Regular" could be found, because the font is not embedded... like my own fonts..
> I tried it back to version 2.0.12 - always the same behavior.
