public class TestPdfPageImage {

    @Test
    public void testGetPageImage() throws IOException {
        try (PDDocument pdDocument = PDDocument.load(FileUtils.toFile(getClass().getResource("/bad_page_image.pdf")))) {
            final PDFRenderer pdfRenderer = new PDFRenderer(pdDocument);

            final BufferedImage bufferedImage = pdfRenderer.renderImage(0);
            final Path tempPath = Files.createTempFile("es-page-image", ".png");
            try {
                final File tempFile = tempPath.toFile();
                ImageIO.write(bufferedImage, "png", tempFile);

                Assert.assertTrue(Files.size(tempPath) > 0);
            } finally {
                Files.delete(tempPath);
            }
        }
    }
}
{code}
