--------------------------------------
Summary: PDFRendtion : Infinite loop
Key: PDFBOX-4547
URL: https://issues.apache.org/jira/browse/PDFBOX-4547
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.15
Reporter: Bhavesh Kharwa
while processing pdf file for generate rendtion, the following method
_processStreamOperators_ of *org.apache.pdfbox.contentstream.PDFStreamEngine*
class goes into infinite loop. I am using library pdfbox-2.0.15
{code:java}
private void processStreamOperators(PDContentStream contentStream) throws
IOException
{
List<COSBase> arguments = new ArrayList<COSBase>();
PDFStreamParser parser = new PDFStreamParser(contentStream);
Object token = parser.parseNextToken();
while (token != null)
{
if (token instanceof COSObject)
{
arguments.add(((COSObject) token).getObject());
}
else if (token instanceof Operator)
{
processOperator((Operator) token, arguments);
arguments = new ArrayList<COSBase>();
}
else
{
arguments.add((COSBase) token);
}
token = parser.parseNextToken();
}
}
{code}
Generate rendition code for pdf as below:
{code:java}
try (final PDDocument pdf = PDDocument.load(imageBytes)) {
if (pdf != null && pdf.getNumberOfPages() > 0) {
PDFRenderer renderer = new PDFRenderer(pdf);
BufferedImage image = renderer.renderImage(0, 1);
final BufferedImage scaledImage;
if (image.getWidth() > rendition.getWidth()) {
scaledImage =
Thumbnails.of(image).width(rendition.getWidth()).asBufferedImage();
} else {
scaledImage = image;
}
outputBytes =
ImageUtils.writeBufferedImageToBytes(scaledImage, mimeType);
}
}
{code}
