Dominic Tubach commented on PDFBOX-1928:
----------------------------------------
It's OK for me if it is fixed in 2.0, though 1.8.3 changes the behavior of
prior versions
{code}
PDResources resources = ...;
COSBase fontDictionary1 =
resources.getCOSDictionary().getDictionaryObject(COSName.FONT);
// PDFBox <= 1.8.2: an empty COSDictionary is set at COSName.FONT if it is null,
// otherwise nothing is changed
// PDFBox >= 1.8.3: a new COSDictionary with same content is set at COSName.FONT
resources.getFonts();
COSBase fontDictionary2 =
resources.getCOSDictionary().getDictionaryObject(COSName.FONT);
if (fontDictionary1 == fontsDictionary2) {
// PDFBox <= 1.8.2 if fontDictionary1 is not null
} else {
// PDFBox >= 1.8.3
// PDFBox <= 1.8.2 if fontDictionary1 is null
}
{code}
> PDResources.getFonts() and PDresources.getXObjects() change underlying
> COSDictionary
