Roland Quast updated PDFBOX-1018:
---------------------------------
Component/s: (was: PDModel)
Labels: pdfbox (was: )
Priority: Critical (was: Major)
Description:
This bug has been reported in various other tickets submitted before. I am
attempting to conclusively prove that this is an issue, and it needs to be
attended to since all past tickets regarding this bug have been marked invalid.
I have attached a video showing very basic code that will reproduce the issue.
I have also attached the code that causes the issue, as well as a PDF file that
works (a color one), and a black and white PDF file that doesn't.
The main issue is that when reading a black and white PDF file (see attached
black and white pdf file), the following message is displayed, and the contents
of the output image is completely white.
26/05/2011 3:20:14 PM org.apache.pdfbox.util.operator.pagedrawer.Invoke process
WARNING: getRGBImage returned NULL
We use PDFBox in our program for reading PDF files, and at least 50 percent of
our customer's PDF files (from different scanners) will not read because of
this issue. This is a complete show stopper, and I'd be more than happy to help
in any way I could to resolve it.
was:
When converting a PDPage of this pdf into an image, the resulting file is
always a white image with no contents.
The following message appeared in the log output (It doesn't seem to be a
duplicate of PDFBOX-794.) :
ERROR filter.FlateFilter - Stop reading corrupt stream
Here's the code used to convert the image :
@Test
public void testConvertImage() {
try {
PDDocument pdDocument =
PDDocument.load("pdf_causing_white_pages.pdf");
List<PDPage> documentPageList =
pdDocument.getDocumentCatalog().getAllPages();
TestCase.assertNotNull(documentPageList);
int pageNumber = 1;
for (PDPage tmpPage :documentPageList){
BufferedImage tempImage = tmpPage.convertToImage();
ImageIO.write(tempImage,"jpeg", new
File("result_"+pageNumber+".jpeg"));
pageNumber ++;
}
} catch (FileNotFoundException e) {
TestCase.fail(e.getMessage());
} catch (IOException e) {
TestCase.fail(e.getMessage());
}
}
