Description

When rendering page one of the attached PDF the image does not render.

In the logs, I see the following:

2024-09-24 13:25:56:924 [main] WARN COSParser - The end of the stream doesn't point to the correct offset, using workaround to read the stream, stream start position: 196, length: 0, expected end position: 196
2024-09-24 13:25:56:930 [main] WARN PDFStreamEngine - Image stream is empty
java.io.IOException: Image stream is empty

	at org.apache.pdfbox.rendering.PageDrawer.drawImage(PageDrawer.java:1107)

I assume this is a bad PDF, but Acrobat, Chrome, etc., display it without an issue.

Here's the render code used:

File out = File.createTempFile("test-", ".png");
PDDocument pdDocument = Loader.loadPDF(pdf);
final PDFRenderer pdfRenderer = new PDFRenderer(pdDocument);
ImageIO.write(pdfRenderer.renderImageWithDPI(0, 300), "png", out);
