Description

I have the following test:

@Test
public void testPDFBoxBug() throws IOException

{ ClassLoader classLoader = getClass().getClassLoader(); File file = new File(classLoader.getResource("PdfBox_Test.pdf").getFile()); byte[] bytes = Files.readAllBytes(file.toPath()); convertPDFToPNG(bytes); }

private List<String> convertPDFToPNGLight(byte[] input) throws IOException {
List<String> convertedPNGs = new ArrayList<>();
PDDocument doc = PDDocument.load(input);
PDFRenderer renderer = new PDFRenderer(doc);

for(int i = 0; i < doc.getNumberOfPages() ; i++) {
BufferedImage img = null;
img = renderer.renderImageWithDPI(i, 96);

ByteArrayOutputStream out2 = new ByteArrayOutputStream();

ImageIO.write(img, "PNG", out2);

out2.size();

convertedPNGs.add(Base64Utils.encodeToString(out2.toByteArray()));
try (OutputStream outputStream = new FileOutputStream("target/thefilename" + i + ".png"))

{ out2.writeTo(outputStream); }

}
doc.close();
return convertedPNGs;
}

 

My input and output are in attachment.
