Invalid Images Returned
-----------------------
Key: PDFBOX-616
URL: https://issues.apache.org/jira/browse/PDFBOX-616
Project: PDFBox
Issue Type: Bug
Components: PDModel
Affects Versions: 0.8.0-incubator
Environment: Multiple (Windows)
Reporter: James A. Thomas
When getting images from a PDF document using PDXObjectImage (code fragment
below), it returns an image with invalid characteristics. The PDXObjectImage
is not null, but attributes like .getColorSpace() return null. The image has a
height and width, but the getRGBImage() method returns null.
This happens on EVERY image of the attached file. Code fragment and output is
shown below.
Code Fragment:
// Get a list of pages from the input PDF document
List pages = InputDoc.getDocumentCatalog().getAllPages();
// Process each page
int i = 0;
for (Object obj : pages)
{
String Barcode = null;
i++;
PDPage page = (PDPage)obj;
// Get the image on the page and process it
PDResources resources = page.getResources();
Map images = resources.getImages();
System.out.println("Found " + images.size() + " images on
Page " + i);
if( images != null )
{
Iterator imageIter = images.keySet().iterator();
while ( imageIter.hasNext() )
{
String key = (String)imageIter.next();
System.out.println("key = " + key);
PDXObjectImage image = (PDXObjectImage)images.get(
key );
if (image != null)
{
System.out.println("Image subtype = " +
image.SUB_TYPE.toString());
System.out.println("Image suffix = " +
image.getSuffix());
System.out.println("PDX image has height = " +
image.getHeight()
+ " and width " +
image.getWidth());
// Convert image to a Buffered Image, so we can
// look for a barcode and decode it
BufferedImage RGBimage = image.getRGBImage();
if (RGBimage == null)
System.out.println("RGBimage is null");
}
}
}
