Summary: PDPage.convertToImage() throw
java.lang.IndexOutOfBoundsException
Key: PDFBOX-1677
URL: https://issues.apache.org/jira/browse/PDFBOX-1677
Project: PDFBox
Issue Type: Bug
Components: PDFReader, PDModel, Utilities
Affects Versions: 1.8.2, 1.8.1
Environment: JSF1.1+ PdfBox1.8.2+Tomcat (and Weblogic)
Reporter: Javier García Sánchez
Sometimes, a random times, the method PDPage.convertToImage() throw an
exception like java.lang.IndexOutOfBoundsException.
I said sometimes, because is a ramdom process which i cannot understand.
This is my code:
public byte[] getImageOutputStreamFromPdfFile (byte[] inputPDF) throws
IOException,Exception{
logger.info("Utils.getImageOutputStreamFromPdfFile
(byte[] inputPDF)");
//resultado
byte[] result=null;
if (inputPDF!=null && inputPDF.length>0){
long time = System.currentTimeMillis();
InputStream isPDF = null;
//imagen resultado
ByteArrayOutputStream imageOutputStream = null;
try{
isPDF = new
ByteArrayInputStream(inputPDF);
imageOutputStream = new
ByteArrayOutputStream();
//pdf
PDDocument document =
PDDocument.load(isPDF, true);
@SuppressWarnings("unchecked")
List<PDPage> pages =
document.getDocumentCatalog().getAllPages();
List<BufferedImage> imagesList = new
ArrayList<BufferedImage>(
pages.size());
PDPage pDPage = null;
BufferedImage auxImage = null;
// width y height final image
int maxWidth = 0;
int totalHeight = 0;
for (int i = 0; i < pages.size(); i++) {
pDPage = pages.get(i);
// get Image Page
auxImage =
pDPage.convertToImage();
auxImage.flush();
// maxWidth
if (auxImage.getWidth() >
maxWidth) {
maxWidth =
auxImage.getWidth();
}
// totalHeight
totalHeight +=
auxImage.getHeight();
// add image to the list
imagesList.add(i, auxImage);
}
BufferedImage bImageFromConvert = new
BufferedImage(maxWidth,
totalHeight,
BufferedImage.TYPE_INT_ARGB);
Graphics g =
bImageFromConvert.getGraphics();
int auxHeightDraw = 0;
for (BufferedImage img : imagesList) {
g.drawImage(img, 0,
auxHeightDraw, null);
auxHeightDraw +=
img.getHeight();
}
imagesList.clear();
ImageIO.write(bImageFromConvert,
ConstantesProperties.EXTENSION_IMAGE, imageOutputStream);
result=imageOutputStream.toByteArray();
logger.info("Utils.getImageOutputStreamFromPdfFile --> OK: Generation
time:"+(System.currentTimeMillis()-time));
}catch (IOException e) {
logger.error("Utils.getImageOutputStreamFromPdfFile-->"+Utils.stackTraceToString(e));
result=null;
throw e;
}catch (Exception e) {
logger.error("Utils.getImageOutputStreamFromPdfFile-->"+Utils.stackTraceToString(e));
result=null;
throw e;
}finally{
if (isPDF!=null){
isPDF.close();
}
if (imageOutputStream!=null){
imageOutputStream.close();
}
}//end finally
}//end if
return result;
}//end getImageOutputStreamFromPdfFile
