> 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:
> {code:title=Test.java|borderStyle=solid}
> 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();
>     }
>   }
> }
> {code}
