Description

Hi,

While we upload some PDF, we encounter an error like this : "Error: Expected operator 'ID' actual='In' at stream offset 142897 []"

 

We used 2.0.25 pdfbox version and we also tried 2.0.26 and it will also work fine in some pdf, but not with others.

 

Code :

public static boolean extractFirstPdfPageAsImageJPEG(final File sourcePdf, final File resultImg,

                                          final Integer maxWidth, final Integer maxHeight) {

                            try (final PDDocument document = PDDocument.load(sourcePdf)) {

                                          final PDFRenderer pdfRenderer = new PDFRenderer(document);

                                          final BufferedImage extractedImage = pdfRenderer.renderImageWithDPI(0, 100, ImageType.RGB);

 

                                          final int originalHeight = extractedImage.getHeight();

                                          final int originalWidth = extractedImage.getWidth();

 

                                          int scaledHeight = originalHeight;

                                          int scaledWidth = originalWidth;

 

                                          if (originalWidth > maxWidth) {

                                                         scaledWidth = maxWidth;

                                                         scaledHeight = scaledWidth * originalHeight / originalWidth;

                                                         if (scaledHeight > maxHeight)

{                                                                        scaledHeight = maxHeight;                                                                        scaledWidth = scaledHeight * originalWidth / originalHeight;                                                          }

                                          } else if (originalHeight > maxHeight)

{                                                          scaledHeight = maxHeight;                                                          scaledWidth = scaledHeight * originalWidth / originalHeight;                                           }

 

                                          // creates output image

                                          final BufferedImage resizedImage = new BufferedImage(scaledWidth, scaledHeight, extractedImage.getType());

 

                                          final Graphics2D g2d = resizedImage.createGraphics();

                                          g2d.drawImage(extractedImage, 0, 0, scaledWidth, scaledHeight, null);

                                          g2d.dispose();

                                          ImageIO.write(resizedImage, "JPEG", resultImg);

                                          return true;

                            } catch (final IOException e)

{                                           LOG.error(e.getMessage(), e);                                           return false;                             }

              }

 

  this pdfRenderer.renderImageWithDPI(0, 100, ImageType.RGB) method will generate error :

 

Error: Expected operator 'ID' actual='In' at stream offset 142897 []

java.io.IOException: Error: Expected operator 'ID' actual='In' at stream offset 142897

Is it a known bug ? Do you know when it will be fixed ? 

Thanks a lot,

Regards.
