Yeah it's tricky. See also the source code of DrawPrintTextLocations
which was written based on showFontGlyph().
I can't tell whether your code is correct because it's all so complex.
The best is to 1) copy some code that works 2) test with many files.

Hello,
I am trying to render PDFs in JavaFX using PDFBox, mostly as an exercise
for myself.
I am extending PDFGraphicsStreamEngine, and I have come across a
predicament in the method showFontGlyph(Matrix textRenderingMatrix, PDFont
font, int code, String unicode, Vector displacement), namely - how do I get
a GeneralPath for the glyph in question.
It seems each PDFont class has a slightly different way for achieving this,
and I couldn't find any succinct summary of all the methods. So far I have
come up with this bit of code:
GeneralPath gp;
if (font instanceof PDVectorFont) {
PDVectorFont vFont = (PDVectorFont) font;
gp = vFont.getPath(code);
} else if (font instanceof PDSimpleFont) {
if (font instanceof PDType1Font) {
PDType1Font t1Font = (PDType1Font) font;
gp = t1Font.getType1Font().getPath(t1Font.codeToName(code));
} else if (font instanceof PDType1CFont) {
PDType1CFont t1cFont = (PDType1CFont) font;
gp = t1cFont.getPath(t1cFont.codeToName(code));
} else {
// Presumably this should only be PDType3Font, as
PDTrueTypeFont is also a PDVectorFont
PDSimpleFont sFont = ((PDSimpleFont) font);
gp = sFont.getPath(unicode);
}
} else {
// Should never happen?
throw new RuntimeException("Unknown font type");
}
My question is - did I cover all possibilities? Am I doing this correctly?
Or is there some built-in method for achieving the same purpose, which is
agnostic to the type of PDFont given?
Thanks,
Itai.
