Description

Generating an image from PDF generated by pdfTeX-1.40.12 creates empty images (transparent images in png format, and black images in jpeg format), see pdf-nok.pdf and pdf-nok1.png files attached.
However, pdfTeX versions 1.40.10 and 1.40.13 generate pdf files that are correctly converted to images, see pdf-ok.pdf and pdf-ok1.png files attached.

The code used to generate the png files is the following:

Test.java

import java.awt.image.BufferedImage;
import java.io.File;

import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFImageWriter;

public class Test {
  public static void main(String[] args) throws Exception {
    PDDocument docOk = PDDocument.load(new File("pdf-ok.pdf"));
    PDDocument docNok = PDDocument.load(new File("pdf-nok.pdf"));

    PDFImageWriter imagewriter = new PDFImageWriter();
    try {
      imagewriter.writeImage(docOk, "png", null, 1, 1, "pdf-ok",
BufferedImage.TYPE_INT_RGB, 100);
      imagewriter.writeImage(docNok, "png", null, 1, 1, "pdf-nok",
BufferedImage.TYPE_INT_RGB, 100);
    } finally {
      docOk.close();
      docNok.close();
    }
  }
}
