@Test
public void testMultipleFontFileReuse() throws IOException,
URISyntaxException
{
URL url = PDFontTest.class.getClassLoader().getResource(
"org/apache/pdfbox/ttf/LiberationSans-Regular.ttf");
File file = new File(url.toURI());
TrueTypeFont ttf = new TTFParser().parse(file);
for (int i = 0; i < 32; ++i)
{
try (PDDocument doc = new PDDocument())
{
PDPage page = new PDPage();
doc.addPage(page);
PDFont font = PDType0Font.load(doc, ttf, true);
try (PDPageContentStream cs = new PDPageContentStream(doc,
page))
{
cs.beginText();
cs.setFont(font, 10);
cs.showText("testMultipleFontFileReuse");
cs.endText();
}
doc.save(new ByteArrayOutputStream());
}
}
}
{code}
This happens only if the TrueTypeFont is created from a file, not when it is
created from a stream (PDFBOX-3337). It worked in 2.0.0 but no longer since
2.0.1.
